+# كيفية وضع علامة مائية نصية على صفحات المخطط في Java
+
+في مشاريع البرمجيات الحديثة، أصبح حماية الأصول البصرية التي تشاركها—وخاصة المخططات—أولوية قصوى. **كيفية وضع علامة مائية على المخطط** صفحات بنص في Java هو طلب شائع للشركات التي تحتاج إلى الحفاظ على هوية العلامة التجارية، ومنع إعادة الاستخدام غير المصرح به، وتتبع أصل المستند. يشرح هذا الدليل العملية بالكامل باستخدام **GroupDocs.Watermark for Java**، من إعداد البيئة إلى التحقق النهائي، حتى تتمكن من تأمين مخططاتك بثقة.
+
+## إجابات سريعة
+- **ما المكتبة التي تضيف العلامات المائية؟** GroupDocs.Watermark for Java.
+- **ما نسخة Java المطلوبة؟** JDK 8 أو أحدث.
+- **هل أحتاج إلى ترخيص للاختبار؟** ترخيص مؤقت مجاني يعمل للتقييم.
+- **هل يمكنني وضع علامة مائية على عدة صفحات في آن واحد؟** نعم — تطبيق العلامة المائية على جميع الصفحات في استدعاء واحد.
+- **هل العملية فعّالة في استهلاك الذاكرة؟** الـ API يبث الصفحات، لذا حتى المخططات التي تحتوي على 500 صفحة تبقى تحت 200 ميغابايت من الذاكرة.
+
+## ما هو وضع علامة مائية على صفحات المخطط في Java؟
+يتضمن ذلك إضافة نص (أو صور) شبه شفاف إلى كل صفحة من ملف المخطط—مثل Visio أو SVG أو أي تنسيقات مدعومة أخرى—باستخدام مكتبة Java. تصبح العلامة المائية جزءًا من المحتوى البصري، مما يجعلها مرئية في أي عارض مع الحفاظ على بيانات المخطط الأصلية.
+
+## لماذا نستخدم GroupDocs.Watermark for Java؟
+GroupDocs.Watermark يدعم **أكثر من 50 تنسيق إدخال وإخراج**، يعالج الملفات حتى **1 GB** دون تحميل المستند بالكامل في الذاكرة، ويقدم **OCR مدمج** لاكتشاف العلامات المائية الموجودة. هذه القدرات المرقمة تضمن حماية سريعة وموثوقة لمستودعات المخططات الكبيرة، بينما يبسط الـ API دمجه في تطبيقات Java.
+
+## المتطلبات المسبقة
+- **Java Development Kit (JDK)** 8 أو أعلى مثبت على جهازك.
+- IDE مثل **IntelliJ IDEA** أو **Eclipse** لتحرير وتشغيل كود Java.
+- إلمام أساسي بـ Maven لإدارة التبعيات.
+
+### المكتبات والتبعيات المطلوبة
+سنستخدم GroupDocs.Watermark for Java، والذي يمكنك إضافته إلى مشروع Maven الخاص بك:
+
+```xml
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+إذا كنت تفضل الإعداد اليدوي، قم بتحميل الملفات الثنائية من صفحة الإصدار الرسمية [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/) وأضفها إلى مسار الفئة (classpath) الخاص بمشروعك.
+
+### الحصول على الترخيص
+ابدأ بتجربة مجانية عن طريق الحصول على ترخيص مؤقت من [GroupDocs.Trial Licensing](https://purchase.groupdocs.com/temporary-license/). للاستخدام الإنتاجي، اشترِ ترخيصًا كاملاً وضع ملف `license.json` حيث يمكن لتطبيقك قراءته:
+
+```java
+// Load the temporary or purchased license – keep unchanged
+```java
+License license = new License();
+license.setLicense("path/to/license/file");
+```
+```
+
+## دليل التنفيذ
+فيما يلي شرح خطوة بخطوة يوضح بالضبط كيفية تضمين علامة مائية نصية في كل صفحة من المخطط.
+
+### كيف أضيف علامة مائية نصية إلى صفحة مخطط؟
+حمّل المخطط، أنشئ كائن `TextWatermark`، طبّقها على الصفحات المطلوبة، وأخيرًا احفظ الناتج. يتطلب هذا التدفق من البداية إلى النهاية أربع نداءات API مختصرة فقط ويعمل في أقل من ثانية للملفات النموذجية ذات 10 صفحات، مع إمكانية تخصيص الخط، اللون، الشفافية، والدوران.
+
+#### الخطوة 1: تحميل المخطط الخاص بك
+DiagramLoadOptions يخبر المكتبة كيفية قراءة ملفات المخططات، مثل معالجة كلمات المرور أو خيارات تنسيق محددة. أولاً، أنشئ كائن `Watermarker` باستخدام `DiagramLoadOptions`. يمثل هذا الكائن المخطط المصدر في الذاكرة.
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### الخطوة 2: تهيئة العلامة المائية النصية
+`TextWatermark` يحدد النص الظاهر، الخط، اللون، والدوران. يمكنك أيضًا ضبط الشفافية لجعل العلامة المائية خفيفة.
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### الخطوة 3: إضافة العلامة المائية إلى صفحات المخطط
+DiagramShapeWatermarkOptions يضبط كيفية تطبيق العلامة المائية على أشكال المخطط. DiagramWatermarkPlacementType يحدد ما إذا كانت العلامة المائية تظهر في المقدمة أو الخلفية. طبّق العلامة المائية على جميع الصفحات الخلفية (أو نطاق صفحات مخصص). الـ API يبث كل صفحة، لذا يبقى استهلاك الذاكرة منخفضًا حتى للملفات الكبيرة.
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### الخطوة 4: حفظ وإغلاق
+احفظ المخطط المموج إلى ملف جديد وأفرغ الموارد.
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### المشكلات الشائعة والحلول
+- **مشكلات مسار الملف:** استخدم مسارات مطلقة أو تحقق من أن دليل العمل يطابق موقع ملفات المخطط.
+- **تعارض الإصدارات:** إصدارات GroupDocs.Watermark مرتبطة بإصدارات JDK محددة؛ تأكد من استخدام نسخة JDK 8‑17 متوافقة.
+- **اختناقات الأداء:** للمعالجة الدفعية، أعد استخدام كائن `Watermarker` واحد واستدعِ `close()` فقط بعد إكمال الدفعة.
+
+## التطبيقات العملية
+العلامات المائية النصية مفيدة في العديد من السيناريوهات الواقعية:
+
+1. **أمان المستندات** – منع المنافسين من إعادة استخدام المخططات المملوكة.
+2. **تعزيز العلامة التجارية** – تضمين اسم الشركة أو الشعار مباشرة على كل صفحة.
+3. **تتبع التعاون** – إضافة الأحرف الأولى للمستخدم أو الطوابع الزمنية لتحديد من قام بتحرير المخطط.
+
+## اعتبارات الأداء
+- **إدارة الذاكرة:** المكتبة تعالج الصفحات بشكل كسول؛ استدعِ دائمًا `watermarker.close()` لتحرير الموارد الأصلية.
+- **حجم العلامة المائية:** الأحجام الأكبر للخط تزيد وقت المعالجة خطيًا؛ حجم خط 12 نقطة هو توازن جيد بين القابلية للقراءة والسرعة.
+- **اختبار دفعي:** تشغيل روتين وضع العلامة المائية على عينة تمثيلية قبل التوسع إلى آلاف الملفات.
+
+## الخلاصة
+أصبح لديك الآن طريقة كاملة وجاهزة للإنتاج **كيفية وضع علامة مائية على المخطط** بنص في Java باستخدام GroupDocs.Watermark. هذه القدرة لا تؤمن أصولك البصرية فحسب، بل تعزز أيضًا اتساق العلامة التجارية عبر جميع المخططات المشتركة.
+
+### الخطوات التالية
+- استكشاف العلامات المائية الصورية لتعزيز العلامة البصرية.
+- دمج العلامات المائية النصية والصورية لحماية متعددة الطبقات.
+- دمج تدفق وضع العلامة المائية في خط أنابيب CI/CD الخاص بك لأتمتة أمان المخططات.
+
+## الأسئلة المتكررة
+1. **هل يمكنني استخدام GroupDocs.Watermark لتنسيقات ملفات أخرى؟**
+ نعم — أكثر من 50 تنسيقًا، بما في ذلك PDF و DOCX و PPTX و SVG، مدعومة.
+
+2. **هل هناك حد لعدد العلامات المائية التي يمكنني إضافتها؟**
+ لا حد صريح، لكن إضافة أكثر من 10 علامات مائية لكل صفحة قد يؤثر على سرعة العرض.
+
+3. **كيف أزيل العلامة المائية من المخطط؟**
+ استخدم API `Watermarker.removeWatermarks()` لاكتشاف وحذف العلامات المائية الموجودة.
+
+4. **هل يمكنني استهداف صفحات محددة فقط؟**
+ بالتأكيد — قم بتكوين `WatermarkOptions` بنطاق صفحات أو شرط مخصص.
+
+5. **ماذا أفعل إذا لم تظهر العلامة المائية؟**
+ تحقق من إعدادات الشفافية، وتباين اللون، وزاوية الدوران؛ راجع وثائق الـ API للتصحيح.
+
+### أسئلة وإجابات إضافية
+**س: هل المكتبة تدعم المخططات المحمية بكلمة مرور؟**
+ج: نعم — مرّر كلمة المرور إلى `DiagramLoadOptions` عند تحميل الملف.
+
+**س: هل يمكنني تشغيل هذا على خادم بدون واجهة رسومية؟**
+ج: الـ API يعمل بالكامل على الخادم ولا يتطلب مكونات GUI.
+
+**س: ما إصدارات Java المدعومة رسميًا؟**
+ج: تم اختبار وتوثيق Java 8 حتى Java 17.
+
+**س: كيف يتعامل GroupDocs.Watermark مع الملفات الكبيرة؟**
+ج: يبث الصفحات، مما يحافظ على استهلاك الذاكرة القصوى تحت 200 ميغابايت حتى للرسوم التي حجمها 1 GB.
+
+**س: هل هناك طريقة لمعاينة العلامة المائية قبل الحفظ؟**
+ج: استخدم `Watermarker.getResultImage()` لإنشاء صورة معاينة لأي صفحة.

+
+## كيفية استبدال صور المخطط في Java خطوة بخطوة
+
+### كيف تقوم بتهيئة Watermarker لملف مخطط؟
+Watermarker هو الصف الرئيسي الذي يمثل مستندًا ويوفر طرقًا للتلاعب بالمحتوى. للبدء، أنشئ كائن `Watermarker` يحمل ملف المخطط في الذاكرة. صف `Watermarker` هو نقطة الدخول الأساسية لـ GroupDocs.Watermark، مما يتيح لك قراءة المستندات وتعديلها وحفظها. استخدم `DiagramLoadOptions` لتحديد إعدادات خاصة بالتنسيق مثل DPI أو نطاق الصفحات. `DiagramLoadOptions` يكوّن طريقة تحميل المخطط، على سبيل المثال تحديد DPI أو وضع التحميل.
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### كيف يمكنك الوصول إلى محتوى المخطط لتحديد الأشكال؟
+بعد تحميل الملف، استرجع كائن `DiagramContent` من `Watermarker`. `DiagramContent` يمثل الهيكل الداخلي للمخطط من صفحات وأشكال. هذا النموذج يعرّض مجموعات من الصفحات والأشكال التي يمكنك التنقل خلالها، مما يسهل تحديد العناصر المحددة مثل الصور أو النص.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### كيف تستبدل صور الأشكال في المخطط؟
+تجول عبر كل `DiagramShape` في الصفحة المطلوبة، تحقق مما إذا كان الشكل يحتوي على صورة، واستبدل بايتات الصورة ببايتات ملف جديد. `DiagramShape` هو النموذج لشكل فردي في المخطط، بينما `DiagramWatermarkableImage` يخزن بيانات الصورة التي يمكن تطبيقها على الشكل.
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### كيف تحفظ التغييرات وتغلق Watermarker؟
+عند اكتمال جميع التعديلات، استدعِ `save` على `Watermarker` لكتابة المخطط المحدث إلى ملف، ثم استدعِ `close` لتحرير الموارد الأصلية. هذا يضمن تحرير مقبض الملف ويمنع تسرب الذاكرة، خاصةً عند معالجة عدد كبير من المخططات في مهمة دفعة.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+
+public class FeatureSaveAndCloseWatermarker {
+ public static void run(Watermarker watermarker) throws Exception {
+ String outputPath = "YOUR_OUTPUT_DIRECTORY/output.vsdx";
+ watermarker.save(outputPath);
+ watermarker.close();
+ }
+}
+```
+```
+
+## إضافة علامة مائية إلى نفس المخطط (اختياري)
+
+إذا كنت تحتاج أيضًا إلى تمييز المخطط، يمكنك إضافة علامة مائية قبل أو بعد استبدال الصورة:
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+
+## المشكلات الشائعة واستكشاف الأخطاء
+
+| العَرَض | السبب المحتمل | الحل |
+|---------|--------------|-----|
+| لم يحدث تغيير في الصورة بعد تشغيل الشيفرة | `DiagramShape.hasImage()` أرجع false | تحقق من نوع الشكل؛ بعض الأشكال المتجهية تخزن الصور بطريقة مختلفة. |
+| خطأ OutOfMemoryError في الملفات الكبيرة | تحميل المخطط بالكامل مرة واحدة | استخدم `DiagramLoadOptions.setLoadMode(LoadMode.Stream)` لمعالجة الصفحات بشكل متسلسل. |
+| العلامة المائية غير مرئية | العلامة المائية وضعت خلف المحتوى الموجود | استدعِ `watermarker.setWatermarkPosition(Position.Foreground)` قبل الحفظ. |
+
+## الأسئلة المتكررة
+
+**س: هل يمكنني استبدال الصور في المخططات المحمية بكلمة مرور؟**
+ج: نعم. مرّر كلمة المرور إلى `DiagramLoadOptions` عند إنشاء `Watermarker`.
+
+**س: هل تعمل المكتبة مع ملفات .drawio (XML)؟**
+ج: بالتأكيد – GroupDocs.Watermark يدعم تنسيق Draw.io XML ويعامل كل عقدة كشكل.
+
+**س: كم عدد المخططات التي يمكنني معالجتها بالتوازي؟**
+ج: المكتبة آمنة للقراءة المتعددة الخيوط للعمليات القراءة فقط؛ بالنسبة لعمليات الكتابة، حدّ التوازي بعدد نوى المعالج لتجنب التنافس على مقابض الملفات.
+
+**س: هل هناك حد لحجم الصورة؟**
+ج: تدعم الصور حتى 100 MB؛ يجب تصغير الملفات الأكبر مسبقًا لتقليل استهلاك الذاكرة.
+
+**س: ما خيارات الترخيص المتاحة؟**
+ج: يمكنك البدء بتجربة مجانية لمدة 30 يومًا؛ الاستخدام في الإنتاج يتطلب ترخيصًا مدفوعًا يمكن الحصول عليه من متجر GroupDocs.

+# حماية مخططات الملكية الفكرية باستخدام GroupDocs.Watermark
+
+تعد حماية مخططات الملكية الفكرية خطوة حاسمة لأي منظمة تشارك أصول التصميم أو المخططات الانسيابية أو الرسومات المعمارية. باستخدام GroupDocs.Watermark for Java يمكنك تحميل ملفات المخططات برمجيًا (مثل `.vsdx`)، واكتشاف حالات العلامة المائية للصور، والبحث عن العلامات المائية النصية، وإزالتها بأمان دون إتلاف الرسم الأصلي. يشرح هذا البرنامج التعليمي العملية بالكامل—من إعداد البيئة إلى المعالجة الدفعية لمكتبات المخططات الكبيرة—حتى تتمكن من دمج حماية IP قوية مباشرة في تطبيقات Java الخاصة بك.
+
+## إجابات سريعة
+- **أي مكتبة تتعامل مع علامات مائية للمخططات؟** GroupDocs.Watermark for Java.
+- **هل يمكنني اكتشاف علامة مائية صورة وكذلك نص؟** نعم، توفر API `ImageDctHashSearchCriteria` لاكتشاف الصور و `TextSearchCriteria` للنص.
+- **هل أحتاج إلى ترخيص تجاري لتشغيل الكود؟** ترخيص تجريبي يعمل للتطوير؛ الترخيص المدفوع مطلوب للإنتاج.
+- **هل يدعم المعالجة الدفعية؟** بالتأكيد—تكرار عبر مجلد وتطبيق نفس منطق العلامة المائية على كل ملف.
+- **هل سيبقى تخطيط المخطط الأصلي سليمًا بعد الإزالة؟** المكتبة تمسح فقط كائنات العلامة المائية، مع الحفاظ على جميع الأشكال والموصلات والتنسيق.
+
+## ما هي مخططات الملكية الفكرية؟
+مخططات الملكية الفكرية هي تمثيلات بصرية—مثل المخططات الانسيابية، نماذج UML، المخططات الشبكية، أو الرسومات المعمارية—تحتوي على معلومات مملوكة لفرد أو منظمة. غالبًا ما تنقل هذه المخططات عمليات أو تصاميم أو استراتيجيات سرية، مما يجعلها أصولًا قيمة تتطلب حماية ضد النسخ غير المصرح به أو التوزيع أو التعديل. من خلال اعتبارها ملكية فكرية، يمكنك تطبيق تدابير قانونية وتقنية، بما في ذلك العلامات المائية، للحفاظ على التحكم في استخدامها ونشرها.
+
+## لماذا تستخدم GroupDocs.Watermark for Java؟
+يدعم GroupDocs.Watermark **أكثر من 50** تنسيق إدخال وإخراج (بما في ذلك `.vsdx`، `.vdx`، `.vsx`) ويمكنه معالجة مخططات مئات الصفحات دون تحميل الملف بالكامل في الذاكرة، مما يقلل استهلاك RAM بنسبة تصل إلى **70 %** مقارنةً بأساليب تدفق الملفات البسيطة. كما توفر API مقارنة تجزئة صور بدون OCR مدمجة، مما يتيح عمليات `detect image watermark` موثوقة في أقل من **200 ms** لكل مخطط على خادم عادي بسرعة 2.5 GHz.
+
+## المتطلبات المسبقة
+قبل البدء، تأكد من وجود ما يلي:
+
+1. **Java Development Kit (JDK) 8+** – يستخدم الكود واجهات برمجة تطبيقات Java 8 القياسية.
+2. **IDE** – IntelliJ IDEA أو Eclipse أو أي محرر تفضله.
+3. **GroupDocs.Watermark for Java** – إما عبر Maven أو تحميل JAR يدويًا.
+
+### المكتبات والاعتمادات المطلوبة

+
+## كيف تقوم بتهيئة Watermarker؟
+إنشاء مثيل `Watermarker` هو الخطوة الأولى في أي سير عمل للعلامات المائية. تقوم فئة `Watermarker` بتحميل ملف المخطط إلى الذاكرة وتوفر طرقًا للبحث، الإضافة، والإزالة. بتمرير مسار المخطط و`DiagramLoadOptions` الاختيارية، تحصل على كائن يُعد النقطة المركزية لجميع العمليات اللاحقة، مما يضمن معالجة متسقة للمستند طوال العملية.
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## كيف تقوم بتحميل مستند مخطط؟
+يمنحك تحميل مخطط باستخدام `DiagramLoadOptions` تحكمًا دقيقًا في طريقة تحليل الملف. تسمح لك `DiagramLoadOptions` بتحديد ما إذا كنت تريد تحميل الصفحات المرئية فقط، أو الحفاظ على الطبقات المخفية، وكيفية التعامل مع الخطوط المدمجة. يمكن لضبط هذه الخيارات تحسين الأداء بشكل كبير للمخططات الكبيرة ويضمن معالجة الأجزاء الضرورية فقط من الملف، مما يقلل استهلاك الذاكرة ويسرع اكتشاف العلامات المائية.
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## كيف تكتشف علامة مائية صورة في مخطط؟
+يعتمد اكتشاف العلامات المائية للصور على الفئة `ImageDctHashSearchCriteria`، التي تحسب تجزئة إدراكية لصورة مرجعية وتقارنها مع كل صورة مدمجة في المخطط. هذه الطريقة سريعة وتتحمل الاختلافات البصرية الطفيفة، مما يتيح لك تحديد الشعارات أو العلامات الرسومية حتى وإن تم تغيير حجمها أو تعديلها قليلاً. من خلال ضبط عتبة التشابه، يمكنك موازنة حساسية الاكتشاف مع تقليل الإيجابيات الزائفة.
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## كيف تبحث عن علامات مائية نصية؟
+يستخدم البحث عن العلامات المائية النصية الفئة `TextSearchCriteria`. تقوم هذه الفئة بمسح جميع الطبقات النصية داخل المخطط، بما في ذلك تلك داخل الأشكال والموصلات والمجموعات، وتعيد أي تطابق يحتوي على السلسلة أو النمط المحدد. البحث غير حساس لحالة الأحرف بشكل افتراضي ويمكن تحسينه باستخدام تعبيرات منتظمة، مما يتيح لك العثور على العلامات المائية التي قد تكون مائلة أو مخفية جزئيًا أو مدمجة في هياكل مخططات معقدة.
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## كيف تزيل العلامات المائية من مخطط؟
+يتم إزالة العلامات المائية عن طريق استدعاء طريقة `clear()` على كل كائن `Watermark` تم إرجاعه من عملية البحث. تحذف طريقة `clear()` فقط العناصر البصرية للعلامة المائية مع ترك كائنات المخطط الأساسية—مثل الأشكال والموصلات والتنسيق—سليمة. بعد الإزالة، احفظ المستند باستخدام طريقة `save`، لتنتج نسخة نظيفة من المخطط تحتفظ بتخطيطه ووظائفه الأصلية.
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## التطبيقات العملية
+- **تكامل برمجيات المؤسسات:** دمج التحقق من العلامة المائية في أنظمة إدارة المستندات لفرض سياسات الملكية الفكرية تلقائيًا.
+- **أنظمة إدارة المحتوى (CMS):** فحص المخططات التي يرفعها المستخدمون للبحث عن شعارات غير مصرح بها قبل النشر.
+- **معالجة المستندات القانونية:** اكتشاف وإزالة العلامات المائية السرية عند إعداد حزم الأدلة.
+
+## الأخطاء الشائعة واستكشاف الأخطاء وإصلاحها
+- **استثناء الترخيص المفقود:** تأكد من أن ملف الترخيص التجريبي أو المدفوع مُشار إليه بشكل صحيح عبر `License.setLicense("license_path")`.
+- **تباطؤ المخططات الكبيرة:** فعّل `loadOptions.setLoadHiddenLayers(false)` وفكّر في معالجة المخططات عبر تدفقات متوازية.
+- **مطابقات صور زائفة:** اضبط تسامح تجزئة DCT باستخدام `criteria.setSimilarityThreshold(0.85)` لتقليل المطابقات غير المقصودة.
+
+## الأسئلة المتكررة
+
+**س: هل يمكنني البحث عن كل من العلامات المائية النصية والصورية في استدعاء واحد؟**
+ج: نعم، اجمع المعايير باستخدام `OrSearchCriteria` (مثال: `new OrSearchCriteria(textCriteria, imageCriteria)`) لاسترجاع النوعين في آن واحد.
+
+**س: هل سيؤدي إزالة العلامات المائية إلى إتلاف تخطيط المخطط؟**
+ج: لا. تقوم المكتبة بعزل كائنات العلامة المائية، لذا تبقى الأشكال والموصلات والتنسيق دون تغيير بعد `clear()`.
+
+**س: ما هي صيغ المخططات المدعومة؟**
+ج: يدعم GroupDocs.Watermark `.vsdx`، `.vdx`، `.vsx`، والعديد من صيغ Visio القديمة، ما يغطي أكثر من **30** نوعًا من المخططات.
+
+**س: كيف يمكنني معالجة آلاف المخططات بكفاءة؟**
+ج: استخدم `ExecutorService` في Java لتشغيل اكتشاف/إزالة العلامات المائية في دفعات متوازية، وأعد استخدام كائن تكوين `Watermarker` واحد لتقليل الحمل.
+
+**س: هل يمكن دمجه في خط أنابيب CI/CD؟**
+ج: بالتأكيد. أضف مقتطفات Java إلى سكريبتات البناء (Maven/Gradle) وشغّلها كخطوة تحقق قبل النشر لضمان عدم وجود علامات مائية محظورة.

+DiagramLoadOptions 告诉库如何读取图表文件，例如处理密码或特定格式选项。首先，用 `DiagramLoadOptions` 实例化一个 `Watermarker`。该对象在内存中表示源图表。
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### 步骤 2：初始化文字水印
+`TextWatermark` 定义可见的文本、字体、颜色和旋转。您还可以设置不透明度，使水印更为柔和。
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### 步骤 3：将水印添加到图表页面
+DiagramShapeWatermarkOptions 配置水印在图表形状上的应用方式。DiagramWatermarkPlacementType 指定水印是显示在前景还是背景。将水印应用于所有背景页面（或自定义页面范围）。API 会流式处理每一页，即使是大文件也能保持低内存使用。
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### 步骤 4：保存并关闭
+将带水印的图表持久化到新文件并释放资源。
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### 常见问题及解决方案
+- **文件路径问题：** 使用绝对路径或确认工作目录与图表文件所在位置匹配。
+- **版本不匹配：** GroupDocs.Watermark 的发布与特定 JDK 版本绑定；请确保使用兼容的 JDK 8‑17 构建。
+- **性能瓶颈：** 对于批量处理，复用单个 `Watermarker` 实例，并在批处理完成后才调用 `close()`。
+
+## 实际应用
+文字水印在许多实际场景中非常有用：
+
+1. **文档安全** – 防止竞争对手重新使用专有图表。
+2. **品牌强化** – 将公司名称或口号直接嵌入每一页。
+3. **协作追踪** – 添加用户首字母或时间戳，以指示谁编辑了图表。
+
+## 性能考虑因素
+- **内存管理：** 库懒加载页面；始终调用 `watermarker.close()` 以释放本地资源。
+- **水印大小：** 更大的字体会线性增加处理时间；12 pt 字体在可读性和速度之间取得良好平衡。
+- **批量测试：** 在扩展到数千个文件之前，在代表性样本上运行水印例程。
+
+## 结论
+现在，您已经拥有使用 GroupDocs.Watermark 在 Java 中为图表页面添加文字水印的完整、可投入生产的方法。此功能不仅保护了您的视觉资产，还在所有共享的图表中强化了品牌一致性。
+
+### 后续步骤
+- 探索图像水印，以实现额外的视觉品牌化。
+- 将文字和图像水印结合，实现多层保护。
+- 将水印流程集成到 CI/CD 流水线中，实现图表安全的自动化。
+

+手动更新图表文件中的图像既耗时又容易出错。在本教程中，您将学习如何仅用几行代码 **在 Java 中替换图表图像**，并且在需要时了解如何 **向图表添加水印**。完成后，您将拥有一个可在任何使用 Visio、Draw.io 或其他受支持图表格式的 Java 项目中直接使用的可复用代码片段。
+
+## 快速答案
+- **什么库处理图表图像替换？** GroupDocs.Watermark for Java.
+- **基本替换需要多少行代码？** 在创建 Watermarker 后仅需三行代码。
+- **我可以同时添加水印吗？** 可以——使用相同的 Watermarker 实例并配合水印对象。
+- **需要哪个 Java 版本？** JDK 8 或更高。
+- **生产使用是否需要许可证？** 需要有效的 GroupDocs.Watermark 许可证；提供免费试用。
+
+## 什么是 Java 中的图表图像替换？
+在 Java 中替换图表图像是指通过编程方式在图表文件（如 .vsdx、.drawio 或 .svg）中查找包含位图的形状，并使用 GroupDocs.Watermark API 将这些嵌入的图像替换为新的图像。这可以自动化本需在图表编辑器中手动编辑的更新工作。
+
+## 为什么使用 GroupDocs.Watermark 进行图表图像替换？
+GroupDocs.Watermark 支持 **50 多种输入和输出格式**——包括 Visio、Draw.io 和 SVG——并且能够在不将整个文档加载到内存中的情况下处理 **最高达 500 MB 的文件**，相较于传统的文件流方式可实现 **30 % 的 CPU 使用率降低**。
+
+## 前提条件
+- JDK 8 或更高版本已安装。
+- 用于 Java 开发的 IDE（IntelliJ IDEA、Eclipse 或 VS Code）。
+- Maven（或手动添加 JAR 的能力）。
+- 有效的 GroupDocs.Watermark 许可证（试用或永久）。您可以从 [GroupDocs](https://purchase.groupdocs.com/temporary-license/) 获取许可证。
+
+### 必需的库、版本和依赖项
+在您的 `pom.xml` 中添加 GroupDocs.Watermark 仓库和依赖项：
+
+```xml
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+如果您更喜欢手动管理 JAR，请从官方网站下载最新发布版本：[GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/).
+
+## 如何在 Java 中逐步替换图表图像
+
+### 如何为图表文件初始化 Watermarker？
+Watermarker 是表示文档并提供内容操作方法的主要类。首先，创建一个加载图表文件到内存的 `Watermarker` 对象。`Watermarker` 类是 GroupDocs.Watermark 的核心入口，允许您读取、修改和保存文档。使用 `DiagramLoadOptions` 指定特定格式的设置，例如 DPI 或页面范围。`DiagramLoadOptions` 配置图表的加载方式，例如设置 DPI 或加载模式。
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### 如何访问图表内容以定位形状？
+加载文件后，从 `Watermarker` 中获取 `DiagramContent` 对象。`DiagramContent` 表示图表的页面和形状的内部层次结构。该模型公开页面和形状的集合，您可以遍历它们，从而轻松定位图像或文本等特定元素。
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### 如何在图表中替换形状图像？
+遍历目标页面上的每个 `DiagramShape`，检查该形状是否包含图像，并将图像字节替换为新文件的字节。`DiagramShape` 是图表中单个形状的模型，而 `DiagramWatermarkableImage` 存储可应用于形状的图像数据。
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### 如何保存更改并关闭 Watermarker？
+当所有修改完成后，调用 `Watermarker` 的 `save` 方法将更新后的图表写入文件，然后调用 `close` 释放本地资源。这可确保文件句柄被释放，防止内存泄漏，尤其是在批量处理大量图表时。
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+
+public class FeatureSaveAndCloseWatermarker {
+ public static void run(Watermarker watermarker) throws Exception {
+ String outputPath = "YOUR_OUTPUT_DIRECTORY/output.vsdx";
+ watermarker.save(outputPath);
+ watermarker.close();
+ }
+}
+```
+```
+
+## 向同一图表添加水印（可选）
+
+如果您还需要对图表进行品牌化，可以在图像替换前后添加水印：
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+
+## 常见问题和故障排除
+
+| 症状 | 可能原因 | 解决办法 |
+|---------|--------------|-----|
+| 运行代码后图像未变化 | `DiagramShape.hasImage()` 返回 false | 验证形状类型；某些矢量形状的图像存储方式不同。 |
+| 大文件出现 OutOfMemoryError | 一次性加载整个图表 | 使用 `DiagramLoadOptions.setLoadMode(LoadMode.Stream)` 逐页顺序处理。 |
+| 水印不可见 | 水印被放置在现有内容之后 | 在保存前调用 `watermarker.setWatermarkPosition(Position.Foreground)`。 |
+
+## 常见问答
+
+**问：我可以替换受密码保护的图表中的图像吗？**
+答：可以。在创建 `Watermarker` 时将密码传递给 `DiagramLoadOptions`。
+
+**问：该库是否支持 .drawio（XML）文件？**
+答：完全支持——GroupDocs.Watermark 支持 Draw.io XML 格式，并将每个节点视为形状。
+
+**问：我可以并行处理多少个图表？**
+答：该库对只读操作是线程安全的；对于写操作，请将并发数限制在 CPU 核心数，以避免文件句柄争用。
+
+**问：图像大小有上限吗？**
+答：支持最高 100 MB 的图像；更大的文件应在使用前进行缩放，以保持低内存占用。
+
+**问：有哪些授权选项？**
+答：您可以先使用免费 30 天试用；生产使用需要付费许可证，可从 GroupDocs 商店获取。

+# 使用 GroupDocs.Watermark 保护知识产权图表
+
+保护知识产权图表是任何共享设计资产、流程图或架构图的组织必须采取的关键步骤。使用 GroupDocs.Watermark for Java，您可以以编程方式加载图表文件（如 `.vsdx`），检测图像水印实例，搜索文本水印，并在不损坏原始图纸的情况下安全地将其移除。本教程将带您完成整个过程——从环境搭建到批量处理大型图表库——让您能够直接在 Java 应用程序中嵌入强大的 IP 保护。
+
+## 快速答案
+- **哪个库处理图表水印？** GroupDocs.Watermark for Java。
+- **我可以同时检测图像水印和文本水印吗？** 可以，API 提供 `ImageDctHashSearchCriteria` 用于图像检测，`TextSearchCriteria` 用于文本。
+- **运行代码是否需要商业许可证？** 试用许可证可用于开发；生产环境需要付费许可证。
+- **支持批量处理吗？** 当然——遍历文件夹，对每个文件应用相同的水印逻辑。
+- **移除后原始图表布局会保持完整吗？** 库仅清除水印对象，保留所有形状、连接线和格式。
+
+## 什么是知识产权图表？
+知识产权图表是指包含个人或组织拥有的专有信息的可视化表示——如流程图、UML 模型、网络示意图或建筑图纸。这些图表通常传达机密的流程、设计或策略，是需要防止未经授权复制、分发或篡改的宝贵资产。将其视为知识产权后，您可以采用法律和技术手段（包括水印）来维护对其使用和传播的控制。
+
+## 为什么使用 GroupDocs.Watermark for Java？
+GroupDocs.Watermark 支持 **50+ 输入和输出格式**（包括 `.vsdx`、`.vdx`、`.vsx`），并且能够在不将整个文件加载到内存中的情况下处理数百页的图表，相比传统文件流方式可将 RAM 消耗降低 **70 %**。API 还内置 OCR‑free 图像哈希比较，能够在典型 2.5 GHz 服务器上以 **200 ms** 以下的时间完成 `detect image watermark` 操作。
+
+## 前置条件
+在开始之前，请确保您已具备：
+
+1. **Java Development Kit (JDK) 8+** – 代码使用标准 Java 8 API。
+2. **IDE** – IntelliJ IDEA、Eclipse 或您喜欢的任何编辑器。
+3. **GroupDocs.Watermark for Java** – 可通过 Maven 或手动下载 JAR 获得。
+
+### 必需的库和依赖
+您可以通过 Maven 添加库，也可以直接下载 JAR。
+
+#### Maven 设置
+在 `pom.xml` 文件中添加仓库和依赖项：
+
+```xml
+
+

+
+## 如何初始化 Watermarker？
+创建 `Watermarker` 实例是任何水印工作流的第一步。`Watermarker` 类将图表文件加载到内存，并提供搜索、添加和移除水印的方法。通过传入图表路径和可选的 `DiagramLoadOptions`，您即可获得一个对象，作为后续所有操作的中心点，确保在整个流程中对文档进行一致处理。
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## 如何加载图表文档？
+使用 `DiagramLoadOptions` 加载图表可让您细粒度控制文件的解析方式。`DiagramLoadOptions` 允许您指定是否仅加载可见页面、是否保留隐藏图层以及如何处理嵌入字体。调整这些选项可以显著提升大图表的性能，并确保仅处理文件的必要部分，从而降低内存使用并加快水印检测速度。
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## 如何在图表中检测图像水印？
+检测图像水印依赖 `ImageDctHashSearchCriteria` 类，该类计算参考图像的感知哈希，并将其与图表中每个嵌入图像进行比较。此方法快速且容忍轻微的视觉差异，能够定位即使被缩放或略微修改的徽标或其他图形水印。通过配置相似度阈值，您可以在检测灵敏度与误报之间取得平衡。
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## 如何搜索文本水印？
+搜索文本水印使用 `TextSearchCriteria` 类。该类会扫描图表中的所有文本层，包括形状、连接线和分组内部的文本，并返回包含指定字符串或模式的匹配项。搜索默认不区分大小写，并可通过正则表达式进一步细化，使您能够定位可能被旋转、部分隐藏或嵌入复杂图表结构中的水印。
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## 如何从图表中移除水印？
+移除水印通过对搜索操作返回的每个 `Watermark` 对象调用 `clear()` 方法来完成。`clear()` 方法仅删除可视的水印元素，而保留底层的图表对象——如形状、连接线和格式——保持完整。清除后，使用 `save` 方法保存文档，即可得到一个保持原始布局和功能的干净图表版本。
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## 实际应用场景
+- **企业软件集成：** 将水印验证嵌入文档管理系统，自动执行 IP 策略。
+- **内容管理系统 (CMS)：** 在发布前扫描用户上传的图表，检测未经授权的徽标。
+- **法律文档处理：** 在准备证据包时检测并剥离机密水印。
+
+## 常见问题与故障排除
+- **缺少许可证异常：** 确保通过 `License.setLicense("license_path")` 正确引用试用或付费许可证文件。
+- **大型图表性能下降：** 启用 `loadOptions.setLoadHiddenLayers(false)`，并考虑使用并行流处理图表。
+- **图像误报匹配：** 使用 `criteria.setSimilarityThreshold(0.85)` 调整 DCT 哈希容差，以减少意外匹配。
+
+## 常见问答
+
+**问：我可以在一次调用中同时搜索文本和图像水印吗？**
+答：可以，使用 `OrSearchCriteria`（例如 `new OrSearchCriteria(textCriteria, imageCriteria)`）一次性检索两种类型。
+
+**问：移除水印会破坏图表布局吗？**
+答：不会。库会隔离水印对象，`clear()` 后形状、连接线和格式保持不变。
+
+**问：支持哪些图表格式？**
+答：GroupDocs.Watermark 支持 `.vsdx`、`.vdx`、`.vsx` 以及多种旧版 Visio 格式，覆盖超过 **30** 种图表类型。
+
+**问：如何高效处理成千上万的图表？**
+答：使用 Java 的 `ExecutorService` 并行批处理水印检测/移除，并复用单个 `Watermarker` 配置对象以降低开销。
+
+**问：能否将其集成到 CI/CD 流水线中？**
+答：完全可以。将 Java 代码片段加入构建脚本（Maven/Gradle），在部署前作为验证步骤运行，确保不存在禁止的水印。

+# Jak v Java vodoznakovat stránky diagramu textem
+
+V moderních softwarových projektech se ochrana vizuálních aktiv, které sdílíte — zejména diagramů — stala prioritou číslo jedna. **How to watermark diagram** stránky s textem v Javě jsou běžnou požadavkem pro společnosti, které potřebují zachovat identitu značky, zabránit neoprávněnému opětovnému použití a sledovat původ dokumentu. Tento tutoriál vás provede celým procesem pomocí **GroupDocs.Watermark for Java**, od přípravy prostředí až po finální ověření, abyste mohli sebejistě zabezpečit své diagramy.
+
+## Rychlé odpovědi
+- **Která knihovna přidává vodoznaky?** GroupDocs.Watermark for Java.
+- **Která verze Javy je požadována?** JDK 8 nebo novější.
+- **Potřebuji licenci pro testování?** Bezplatná dočasná licence funguje pro hodnocení.
+- **Mohu vodoznakovat více stránek najednou?** Ano — aplikujte vodoznak na všechny stránky jedním voláním.
+- **Je proces paměťově efektivní?** API streamuje stránky, takže i diagramy o 500 stránkách zůstávají pod 200 MB RAM.
+
+## Co je vodoznakování stránek diagramu v Javě?
+Jedná se o programové překrytí poloprůhledným textem (nebo obrázky) na každou stránku souboru diagramu — například Visio, SVG nebo jiné podporované formáty — pomocí Java knihovny. Vodoznak se stane součástí vizuálního obsahu, je viditelný v jakémkoli prohlížeči a zároveň zachovává původní data diagramu.
+
+## Proč používat GroupDocs.Watermark pro Java?
+GroupDocs.Watermark podporuje **50+ vstupních a výstupních formátů**, zpracovává soubory až do **1 GB** bez načítání celého dokumentu do paměti a nabízí **vestavěné OCR** pro detekci existujících vodoznaků. Tyto kvantifikované schopnosti zajišťují rychlou, spolehlivou ochranu pro rozsáhlé repozitáře diagramů, zatímco jeho API zjednodušuje integraci do Java aplikací.
+
+## Požadavky
+- **Java Development Kit (JDK)** 8 nebo vyšší nainstalovaný na vašem počítači.
+- IDE jako **IntelliJ IDEA** nebo **Eclipse** pro úpravu a spouštění Java kódu.
+- Základní znalost Maven pro správu závislostí.
+
+### Požadované knihovny a závislosti
+Použijeme GroupDocs.Watermark pro Java, který můžete přidat do svého Maven projektu:
+
+```xml
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Pokud dáváte přednost ručnímu nastavení, stáhněte binární soubory z oficiální stránky vydání [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/) a přidejte je do classpath vašeho projektu.
+
+### Získání licence
+Začněte s bezplatnou zkušební verzí získáním dočasné licence z [GroupDocs.Trial Licensing](https://purchase.groupdocs.com/temporary-license/). Pro produkční použití zakupte plnou licenci a umístěte soubor `license.json` tam, kde ji vaše aplikace může načíst:
+
+```java
+// Load the temporary or purchased license – keep unchanged
+```java
+License license = new License();
+license.setLicense("path/to/license/file");
+```
+```
+
+## Průvodce implementací
+Níže je podrobný průvodce, který ukazuje, jak přesně vložit textový vodoznak na každou stránku diagramu.
+
+### Jak přidat textový vodoznak na stránku diagramu?
+Načtěte diagram, vytvořte objekt `TextWatermark`, aplikujte jej na požadované stránky a nakonec uložte výstup. Tento end‑to‑end tok vyžaduje pouze čtyři stručná volání API a běží za méně než sekundu pro typické soubory o 10 stránkách, přičemž umožňuje přizpůsobení písma, barvy, opacity a rotace.
+
+#### Krok 1: načtěte svůj diagram
+DiagramLoadOptions říká knihovně, jak číst soubory diagramu, například jak zacházet s hesly nebo specifickými možnostmi formátu. Nejprve vytvořte instanci `Watermarker` s `DiagramLoadOptions`. Tento objekt představuje zdrojový diagram v paměti.
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### Krok 2: inicializujte textový vodoznak
+`TextWatermark` definuje viditelný text, písmo, barvu a rotaci. Můžete také nastavit opacity, aby byl vodoznak nenápadný.
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### Krok 3: přidejte vodoznak na stránky diagramu
+DiagramShapeWatermarkOptions konfiguruje, jak je vodoznak aplikován na tvary diagramu. DiagramWatermarkPlacementType určuje, zda se vodoznak zobrazí v popředí nebo pozadí. Aplikujte vodoznak na všechny stránky v pozadí (nebo na vlastní rozsah stránek). API streamuje každou stránku, takže využití paměti zůstává nízké i u velkých souborů.
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### Krok 4: uložte a zavřete
+Uložte vodoznakovaný diagram do nového souboru a uvolněte prostředky.
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### Časté problémy a řešení
+- **Problémy s cestou k souboru:** Používejte absolutní cesty nebo ověřte, že pracovní adresář odpovídá umístění vašich souborů diagramu.
+- **Neshody verzí:** Vydání GroupDocs.Watermark jsou svázána s konkrétními verzemi JDK; ujistěte se, že používáte kompatibilní build JDK 8‑17.
+- **Úzká místa výkonu:** Pro dávkové zpracování znovu použijte jedinou instanci `Watermarker` a volání `close()` proveďte až po dokončení dávky.
+
+## Praktické aplikace
+Textové vodoznaky jsou užitečné v mnoha reálných scénářích:
+
+1. **Zabezpečení dokumentů** – Zabránit konkurenci v opětovném využití proprietárních diagramů.
+2. **Posílení značky** – Vložte název společnosti nebo slogan přímo na každou stránku.
+3. **Sledování spolupráce** – Přidejte iniciály uživatele nebo časové razítko, aby bylo jasné, kdo diagram upravil.
+
+## Úvahy o výkonu
+- **Správa paměti:** Knihovna zpracovává stránky líně; vždy zavolejte `watermarker.close()`, aby se uvolnily nativní zdroje.
+- **Velikost vodoznaku:** Větší velikosti písma zvyšují dobu zpracování lineárně; písmo 12 pt je dobrá rovnováha mezi čitelností a rychlostí.
+- **Testování dávky:** Spusťte rutinu vodoznakování na reprezentativním vzorku před rozšířením na tisíce souborů.
+
+## Závěr
+Nyní máte kompletní, připravenou metodu pro **how to watermark diagram** stránky s textem v Javě pomocí GroupDocs.Watermark. Tato schopnost nejen zabezpečuje vaše vizuální aktiva, ale také posiluje konzistenci značky napříč všemi sdílenými diagramy.
+
+### Další kroky
+- Prozkoumejte obrázkové vodoznaky pro další vizuální branding.
+- Kombinujte textové a obrázkové vodoznaky pro vícevrstvou ochranu.
+- Integrovat tok vodoznakování do vašeho CI/CD pipeline pro automatizaci zabezpečení diagramů.
+
+## Často kladené otázky
+1. **Mohu použít GroupDocs.Watermark pro jiné formáty souborů?**
+ Ano — podporováno je více než 50 formátů, včetně PDF, DOCX, PPTX a SVG.
+2. **Existuje limit, kolik vodoznaků mohu přidat?**
+ Žádný pevný limit, ale přidání více než 10 vodoznaků na stránku může ovlivnit rychlost vykreslování.
+3. **Jak odebrat vodoznak z diagramu?**
+ Použijte API `Watermarker.removeWatermarks()` k detekci a smazání existujících vodoznaků.
+4. **Mohu cílit pouze na konkrétní stránky?**
+ Rozhodně — nakonfigurujte `WatermarkOptions` s rozsahem stránek nebo vlastním predikátem.
+5. **Co mám dělat, pokud vodoznak není viditelný?**
+ Ověřte nastavení opacity, kontrastu barev a rotace; pro řešení problémů konzultujte dokumentaci API.
+
+### Další otázky a odpovědi
+**Q: Podporuje knihovna diagramy chráněné heslem?**
+A: Ano — předávejte heslo do `DiagramLoadOptions` při načítání souboru.
+
+**Q: Můžu to spustit na serveru bez grafického rozhraní?**
+A: API je plně server‑side a nevyžaduje žádné GUI komponenty.
+
+**Q: Které verze Javy jsou oficiálně podporovány?**
+A: Java 8 až Java 17 jsou testovány a dokumentovány.

+# Nahradit obrázky diagramu v Javě pomocí GroupDocs.Watermark
+
+Aktualizace obrázků v souborech diagramů ručně je časově náročná a náchylná k chybám. V tomto tutoriálu se naučíte, jak **nahradit obrázky diagramu v Javě** pomocí několika řádků kódu, a také uvidíte, jak **přidat vodoznak do diagramu**, pokud je potřeba. Na konci budete mít znovupoužitelný úryvek, který můžete vložit do libovolného Java projektu pracujícího s Visio, Draw.io nebo jinými podporovanými formáty diagramů.
+
+## Rychlé odpovědi
+- **Jaká knihovna provádí nahrazení obrázků diagramu?** GroupDocs.Watermark pro Javu.
+- **Kolik řádků kódu je potřeba pro základní nahrazení?** Pouze tři řádky po vytvoření Watermarkeru.
+- **Mohu přidat vodoznak současně?** Ano – použijte stejnou instanci Watermarker s objektem vodoznaku.
+- **Jaká verze Javy je vyžadována?** JDK 8 nebo vyšší.
+- **Potřebuji licenci pro produkční použití?** Je vyžadována platná licence GroupDocs.Watermark; je k dispozici bezplatná zkušební verze.

+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Pokud dáváte přednost ruční správě JAR souborů, stáhněte si nejnovější verzi z oficiální stránky: [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/).
+
+## Jak nahradit obrázky diagramu v Javě krok za krokem
+
+### Jak inicializovat Watermarker pro soubor diagramu?
+Watermarker je hlavní třída, která představuje dokument a poskytuje metody pro manipulaci s obsahem. Pro začátek vytvořte objekt `Watermarker`, který načte soubor diagramu do paměti. Třída `Watermarker` je hlavní vstupní bod GroupDocs.Watermark, který vám umožňuje číst, upravovat a ukládat dokumenty. Použijte `DiagramLoadOptions` k zadání nastavení specifických pro formát, jako je DPI nebo rozsah stránek. `DiagramLoadOptions` konfiguruje, jak je diagram načten, např. nastavení DPI nebo režimu načítání.
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### Jak získat přístup k obsahu diagramu pro vyhledání tvarů?
+Po načtení souboru získejte objekt `DiagramContent` z `Watermarker`. `DiagramContent` představuje vnitřní hierarchii diagramu – stránky a tvary. Tento model poskytuje kolekce stránek a tvarů, přes které můžete iterovat, což usnadňuje vyhledání konkrétních prvků, jako jsou obrázky nebo text.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### Jak nahradit obrázky tvarů v diagramu?
+Projděte smyčkou každou `DiagramShape` na požadované stránce, zkontrolujte, zda tvar obsahuje obrázek, a nahraďte bajty obrázku těmi z nového souboru. `DiagramShape` je model pro jednotlivý tvar v diagramu, zatímco `DiagramWatermarkableImage` ukládá data obrázku, která lze aplikovat na tvar.
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### Jak uložit změny a zavřít Watermarker?
+Po dokončení všech úprav zavolejte `save` na `Watermarker`, aby se aktualizovaný diagram zapsal do souboru, a poté vyvolejte `close` pro uvolnění nativních zdrojů. Tím se zajistí uvolnění souborových handle a zabrání se únikům paměti, zejména při zpracování mnoha diagramů v dávkovém úkolu.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+
+public class FeatureSaveAndCloseWatermarker {
+ public static void run(Watermarker watermarker) throws Exception {
+ String outputPath = "YOUR_OUTPUT_DIRECTORY/output.vsdx";
+ watermarker.save(outputPath);
+ watermarker.close();
+ }
+}
+```
+```
+
+## Přidání vodoznaku do stejného diagramu (volitelné)
+
+Pokud také potřebujete diagram označit, můžete přidat vodoznak před nebo po nahrazení obrázku:
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+
+## Časté problémy a řešení
+
+| Příznak | Předpokládaná příčina | Řešení |
+|---------|-----------------------|--------|
+| Žádná změna obrázku po spuštění kódu | `DiagramShape.hasImage()` vrátil false | Ověřte typ tvaru; některé vektorové tvary ukládají obrázky jinak. |
+| OutOfMemoryError u velkých souborů | Načítání celého diagramu najednou | Použijte `DiagramLoadOptions.setLoadMode(LoadMode.Stream)` pro sekvenční zpracování stránek. |
+| Vodoznak není viditelný | Vodoznak umístěn za existující obsah | Zavolejte `watermarker.setWatermarkPosition(Position.Foreground)` před uložením. |
+
+## Často kladené otázky
+
+**Q: Mohu nahradit obrázky v diagramu chráněném heslem?**
+A: Ano. Předávejte heslo do `DiagramLoadOptions` při vytváření `Watermarker`.
+
+**Q: Pracuje knihovna s .drawio (XML) soubory?**
+A: Rozhodně – GroupDocs.Watermark podporuje formát Draw.io XML a zachází s každým uzlem jako s tvarem.
+
+**Q: Kolik diagramů mohu zpracovávat paralelně?**
+A: Knihovna je vlákny‑bezpečná pro operace jen pro čtení; pro zápis omezte souběžnost na počet CPU jader, aby nedošlo ke konfliktům s souborovými handle.
+
+**Q: Existuje limit velikosti obrázku?**
+A: Obrázky až do 100 MB jsou podporovány; větší soubory by měly být předem zmenšeny, aby se udržovala nízká spotřeba paměti.
+
+**Q: Jaké licenční možnosti jsou k dispozici?**
+A: Můžete začít s bezplatnou 30‑denní zkušební verzí; pro produkční použití je vyžadována placená licence, kterou lze získat v obchodě GroupDocs.

+# Chraňte diagramy duševního vlastnictví pomocí GroupDocs.Watermark
+
+Ochrana diagramů duševního vlastnictví je kritickým krokem pro každou organizaci, která sdílí designové artefakty, vývojové diagramy nebo architektonické výkresy. S GroupDocs.Watermark pro Java můžete programově načíst soubory diagramů (např. `.vsdx`), detekovat instance vodoznaků v obrazech, vyhledávat textové vodoznaky a bezpečně je odstranit, aniž byste poškozovali původní výkres. Tento tutoriál vás provede celým procesem – od nastavení prostředí po dávkové zpracování velkých knihoven diagramů – abyste mohli vložit robustní ochranu IP přímo do svých Java aplikací.
+
+## Rychlé odpovědi
+- **Která knihovna zpracovává vodoznaky diagramů?** GroupDocs.Watermark for Java.
+- **Mohu detekovat vodoznak v obraze i text?** Ano, API poskytuje `ImageDctHashSearchCriteria` pro detekci obrazu a `TextSearchCriteria` pro text.
+- **Potřebuji komerční licenci pro spuštění kódu?** Zkušební licence funguje pro vývoj; pro produkci je vyžadována placená licence.
+- **Je podporováno dávkové zpracování?** Rozhodně – projděte složku a aplikujte stejnou logiku vodoznaku na každý soubor.
+- **Zůstane původní rozvržení diagramu po odstranění nedotčeno?** Knihovna vymaže pouze objekty vodoznaku a zachová všechny tvary, spojnice a formátování.
+
+## Co jsou diagramy duševního vlastnictví?
+Diagramy duševního vlastnictví jsou vizuální reprezentace – například vývojové diagramy, UML modely, síťové schémata nebo architektonické výkresy – které obsahují proprietární informace vlastněné jednotlivcem nebo organizací. Tyto diagramy často předávají důvěrné procesy, návrhy nebo strategie, což z nich činí cenná aktiva vyžadující ochranu proti neoprávněnému kopírování, distribuci nebo úpravám. Považováním těchto diagramů za duševní vlastnictví můžete aplikovat právní a technická opatření, včetně vodoznakování, aby byl zachován kontrola nad jejich používáním a šířením.
+
+## Proč používat GroupDocs.Watermark pro Java?
+GroupDocs.Watermark podporuje **více než 50 vstupních a výstupních formátů** (včetně `.vsdx`, `.vdx`, `.vsx`) a může zpracovávat diagramy o stovkách stránek, aniž by načítal celý soubor do paměti, čímž snižuje spotřebu RAM až o **70 %** ve srovnání s naivními přístupy pomocí file‑streamu. API také nabízí vestavěné porovnání obrazových hashů bez OCR, což umožňuje spolehlivé operace `detect image watermark` za méně než **200 ms** na diagram na typickém 2,5 GHz serveru.
+
+## Předpoklady
+1. **Java Development Kit (JDK) 8+** – kód používá standardní Java 8 API.
+2. **IDE** – IntelliJ IDEA, Eclipse nebo jakýkoli editor, který preferujete.
+3. **GroupDocs.Watermark for Java** – buď přes Maven, nebo ruční stažení JAR.
+
+### Požadované knihovny a závislosti
+Knihovnu můžete přidat přes Maven nebo stáhnout JAR soubory přímo.
+
+#### Nastavení Maven
+Přidejte repozitář a závislosti do souboru `pom.xml`:

+
+## Jak inicializovat Watermarker?
+Vytvoření instance `Watermarker` je prvním krokem v jakémkoli workflow vodoznaku. Třída `Watermarker` načte soubor diagramu do paměti a poskytuje metody pro vyhledávání, přidávání a odstraňování vodoznaků. Předáním cesty k diagramu a volitelných `DiagramLoadOptions` získáte objekt, který slouží jako centrální bod pro všechny následné operace, což zajišťuje konzistentní zpracování dokumentu během celého procesu.
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## Jak načíst dokument diagramu?
+Načtení diagramu s `DiagramLoadOptions` vám dává jemnozrnné řízení toho, jak je soubor parsován. `DiagramLoadOptions` umožňuje specifikovat, zda načíst pouze viditelné stránky, zda zachovat skryté vrstvy a jak zacházet s vloženými fonty. Úprava těchto možností může dramaticky zlepšit výkon u velkých diagramů a zajistit, že budou zpracovány pouze nezbytné části souboru, čímž se sníží využití paměti a urychlí detekce vodoznaků.
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## Jak detekovat vodoznak v obraze v diagramu?
+Detekce obrazových vodoznaků využívá třídu `ImageDctHashSearchCriteria`, která vypočítá percepční hash referenčního obrázku a porovná jej se všemi vloženými obrázky v diagramu. Tato metoda je rychlá a tolerantní k menším vizuálním odchylkám, což vám umožní najít loga nebo jiné grafické vodoznaky i v případě, že byly změněny velikostí nebo mírně upraveny. Nastavením prahu podobnosti můžete vyvážit citlivost detekce proti falešně pozitivním shodám.
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## Jak vyhledat textové vodoznaky?
+Vyhledávání textových vodoznaků používá třídu `TextSearchCriteria`. Tato třída prohledává všechny textové vrstvy v diagramu, včetně těch uvnitř tvarů, spojnic a seskupení, a vrací shody, které obsahují zadaný řetězec nebo vzor. Vyhledávání je ve výchozím nastavení necitlivé na velikost písmen a může být upřesněno regulárními výrazy, což vám umožní najít vodoznaky, které mohou být otočené, částečně skryté nebo vložené do složitých struktur diagramu.
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## Jak odstranit vodoznaky z diagramu?
+Odstraňování vodoznaků se provádí voláním metody `clear()` na každém objektu `Watermark` vráceném vyhledávací operací. Metoda `clear()` smaže pouze vizuální prvky vodoznaku, zatímco podkladové objekty diagramu – jako tvary, spojnice a formátování – zůstávají nedotčeny. Po vyčištění dokument uložíte pomocí metody `save`, čímž získáte čistou verzi diagramu, která zachovává původní rozvržení a funkčnost.
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## Praktické aplikace
+- **Integrace podnikového softwaru:** Vložte validaci vodoznaku do systémů pro správu dokumentů, aby automaticky vynucovaly IP politiky.
+- **Systémy pro správu obsahu (CMS):** Prohledejte diagramy nahrané uživateli na neautorizované loga před publikací.
+- **Zpracování právních dokumentů:** Detekujte a odstraňte důvěrné vodoznaky při přípravě balíčků důkazů.
+
+## Časté úskalí a řešení problémů
+- **Výjimka chybějící licence:** Ujistěte se, že soubor zkušební nebo placené licence je správně odkazován pomocí `License.setLicense("license_path")`.
+- **Zpomalení u velkých diagramů:** Povolením `loadOptions.setLoadHiddenLayers(false)` a zvážením zpracování diagramů v paralelních streamech.
+- **Falešně pozitivní shody obrázků:** Upravte toleranci DCT hash pomocí `criteria.setSimilarityThreshold(0.85)`, aby se snížil počet nechtěných shod.
+
+## Často kladené otázky
+
+**Q: Mohu vyhledat jak textové, tak obrazové vodoznaky v jednom volání?**
+A: Ano, kombinujte kritéria pomocí `OrSearchCriteria` (např. `new OrSearchCriteria(textCriteria, imageCriteria)`) a získáte oba typy najednou.
+
+**Q: Způsobí odstranění vodoznaků poškození rozvržení diagramu?**
+A: Ne. Knihovna izoluje objekty vodoznaku, takže tvary, spojnice a formátování zůstávají po `clear()` beze změny.
+
+**Q: Jaké formáty diagramů jsou podporovány?**
+A: GroupDocs.Watermark zpracovává `.vsdx`, `.vdx`, `.vsx` a několik starších Visio formátů, což pokrývá více než **30** typů diagramů.
+
+**Q: Jak efektivně zpracovat tisíce diagramů?**
+A: Použijte `ExecutorService` v Javě k paralelnímu spouštění detekce/odstraňování vodoznaků ve skupinách a znovu použijte jediný konfigurační objekt `Watermarker` ke snížení režie.
+
+**Q: Je možné integrovat toto do CI/CD pipeline?**
+A: Rozhodně. Přidejte Java úryvky do svých build skriptů (Maven/Gradle) a spusťte je jako krok před nasazením, abyste zajistili, že žádné zakázané vodoznaky nejsou přítomny.

+```
+```
+
+## Implementatie‑gids
+Hieronder vindt u een stap‑voor‑stap walkthrough die precies laat zien hoe u een tekstwatermerk in elke pagina van een diagram kunt insluiten.
+
+### Hoe voeg ik een tekstwatermerk toe aan een diagrampagina?
+Laad het diagram, maak een `TextWatermark`‑object, pas het toe op de gewenste pagina's en sla tenslotte de output op. Deze end‑to‑end flow vereist slechts vier beknopte API‑calls en draait in minder dan een seconde voor typische 10‑pagina bestanden, terwijl u lettertype, kleur, opacity en rotatie kunt aanpassen.
+
+#### Stap 1: laad uw diagram
+DiagramLoadOptions vertelt de bibliotheek hoe diagrambestanden gelezen moeten worden, bijvoorbeeld bij het verwerken van wachtwoorden of specifieke formaatopties. Maak eerst een `Watermarker` aan met `DiagramLoadOptions`. Dit object vertegenwoordigt het bron‑diagram in het geheugen.
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### Stap 2: initialiseert het tekstwatermerk
+`TextWatermark` definieert de zichtbare tekst, het lettertype, de kleur en de rotatie. U kunt ook opacity instellen om het watermerk subtiel te maken.
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### Stap 3: voeg watermerk toe aan diagrampagina's
+DiagramShapeWatermarkOptions configureert hoe een watermerk wordt toegepast op diagramvormen. DiagramWatermarkPlacementType geeft aan of het watermerk in de voorgrond of achtergrond verschijnt. Pas het watermerk toe op alle achtergrondpagina's (of een aangepast paginabereik). De API streamt elke pagina, waardoor het geheugenverbruik laag blijft, zelfs bij grote bestanden.
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### Stap 4: opslaan en sluiten
+Sla het watergemerkte diagram op in een nieuw bestand en maak bronnen vrij.
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### Veelvoorkomende problemen en oplossingen
+- **Problemen met bestands‑paden:** Gebruik absolute paden of controleer of de werkmap overeenkomt met de locatie van uw diagram‑bestanden.
+- **Versiemismatchen:** GroupDocs.Watermark‑releases zijn gekoppeld aan specifieke JDK‑versies; zorg ervoor dat u een compatibele JDK 8‑17‑build gebruikt.
+- **Prestatie‑knelpunten:** Hergebruik een enkele `Watermarker`‑instantie voor batchverwerking en roep `close()` pas aan nadat de batch is voltooid.
+
+## Praktische toepassingen
+Tekstwatermerken zijn nuttig in veel real‑world scenario's:
+
+1. **Documentbeveiliging** – Voorkom dat concurrenten propriëtaire diagrammen hergebruiken.
+2. **Merkversterking** – Integreer de bedrijfsnaam of slogan direct op elke pagina.
+3. **Samenwerkings‑tracking** – Voeg gebruikersinitialen of tijdstempels toe om aan te geven wie een diagram heeft bewerkt.
+
+## Prestatie‑overwegingen
+- **Geheugenbeheer:** De bibliotheek verwerkt pagina's lui; roep altijd `watermarker.close()` aan om native resources vrij te geven.
+- **Watermerk‑grootte:** Grotere lettergroottes verhogen de verwerkingstijd lineair; een 12‑pt lettertype is een goede balans tussen leesbaarheid en snelheid.
+- **Batch‑testen:** Voer de watermerk‑routine uit op een representatieve steekproef voordat u opschaalt naar duizenden bestanden.
+
+## Conclusie
+U heeft nu een complete, productie‑klare methode voor **hoe diagrampagina's watermerken** met tekst in Java met behulp van GroupDocs.Watermark. Deze mogelijkheid beveiligt niet alleen uw visuele assets, maar versterkt ook de merkconsistentie over alle gedeelde diagrammen.
+
+### Volgende stappen
+- Verken afbeeldingswatermerken voor extra visuele branding.
+- Combineer tekst‑ en afbeeldingswatermerken voor meerlagige bescherming.
+- Integreer de watermerk‑stroom in uw CI/CD‑pipeline om diagrambeveiliging te automatiseren.
+
+## Veelgestelde vragen
+1. **Kan ik GroupDocs.Watermark voor andere bestandsformaten gebruiken?**
+ Ja—meer dan 50 formaten, waaronder PDF, DOCX, PPTX en SVG, worden ondersteund.
+
+2. **Is er een limiet aan hoeveel watermerken ik kan toevoegen?**
+ Geen harde limiet, maar meer dan 10 per pagina kan de weergavesnelheid beïnvloeden.
+
+3. **Hoe verwijder ik een watermerk uit een diagram?**
+ Gebruik de `Watermarker.removeWatermarks()`‑API om bestaande watermerken te detecteren en te verwijderen.
+
+4. **Kan ik alleen specifieke pagina's targeten?**
+ Absoluut—configureer `WatermarkOptions` met een paginabereik of een aangepaste predicate.
+
+5. **Wat moet ik doen als het watermerk niet zichtbaar is?**
+ Controleer de opacity, kleurcontrast en rotatie‑instellingen; raadpleeg de API‑documentatie voor probleemoplossing.
+
+### Extra V&A
+**Q: Ondersteunt de bibliotheek wachtwoord‑beveiligde diagrammen?**
+A: Ja—geef het wachtwoord door aan `DiagramLoadOptions` bij het laden van het bestand.
+
+**Q: Kan ik dit op een headless server draaien?**
+A: De API werkt volledig server‑side en vereist geen GUI‑componenten.
+
+**Q: Welke Java‑versies worden officieel ondersteund?**
+A: Java 8 tot en met Java 17 zijn getest en gedocumenteerd.
+
+**Q: Hoe gaat GroupDocs.Watermark om met grote bestanden?**
+A: Het streamt pagina's, waardoor het piekgeheugen onder 200 MB blijft, zelfs voor diagrammen van 1 GB.
+
+**Q: Is er een manier om het watermerk te previewen vóór het opslaan?**
+A: Gebruik `Watermarker.getResultImage()` om een preview‑bitmap van een pagina te genereren.

+# Vervang diagramafbeeldingen in Java met GroupDocs.Watermark
+
+Het handmatig bijwerken van afbeeldingen in diagrambestanden is tijdrovend en foutgevoelig. In deze tutorial leer je hoe je **diagramafbeeldingen in Java** kunt vervangen met slechts een paar regels code, en zie je ook hoe je **een watermerk aan een diagram** kunt toevoegen wanneer nodig. Aan het einde heb je een herbruikbare codefragment die je in elk Java‑project kunt gebruiken dat werkt met Visio, Draw.io of andere ondersteunde diagramformaten.
+
+## Snelle antwoorden
+- **Welke bibliotheek behandelt het vervangen van diagramafbeeldingen?** GroupDocs.Watermark voor Java.
+- **Hoeveel regels code zijn nodig voor een eenvoudige vervanging?** Slechts drie regels nadat de Watermarker is aangemaakt.
+- **Kan ik tegelijkertijd een watermerk toevoegen?** Ja – gebruik dezelfde Watermarker‑instantie met een watermerk‑object.
+- **Welke Java‑versie is vereist?** JDK 8 of hoger.
+- **Heb ik een licentie nodig voor productiegebruik?** Een geldige GroupDocs.Watermark‑licentie is vereist; een gratis proefversie is beschikbaar.
+
+## Wat is diagramafbeeldingen vervangen in Java?
+Diagramafbeeldingen vervangen in Java betekent programmatisch zoeken naar vormen die bitmap‑graphics bevatten binnen een diagrambestand (zoals .vsdx, .drawio of .svg) en die ingebedde afbeeldingen vervangen door nieuwe met behulp van de GroupDocs.Watermark API. Dit automatiseert updates die anders handmatig in een diagrameditor bewerkt moeten worden.
+
+## Waarom GroupDocs.Watermark gebruiken voor het vervangen van diagramafbeeldingen?
+GroupDocs.Watermark ondersteunt **meer dan 50 invoer‑ en uitvoerformaten** – waaronder Visio, Draw.io en SVG – en kan **bestanden tot 500 MB** verwerken zonder het volledige document in het geheugen te laden, waardoor je een **30 % vermindering van CPU‑gebruik** krijgt vergeleken met naïeve bestands‑stream benaderingen.
+
+## Voorvereisten
+- JDK 8 of nieuwer geïnstalleerd.
+- Een IDE (IntelliJ IDEA, Eclipse of VS Code) voor Java‑ontwikkeling.
+- Maven (of de mogelijkheid om JAR‑bestanden handmatig toe te voegen).
+- Een geldige GroupDocs.Watermark‑licentie (proef of permanent). Je kunt een licentie verkrijgen via [GroupDocs](https://purchase.groupdocs.com/temporary-license/).
+
+### Vereiste bibliotheken, versies en afhankelijkheden
+Voeg de GroupDocs.Watermark‑repository en afhankelijkheid toe aan je `pom.xml`:
+
+```xml
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Als je de JAR‑bestanden handmatig wilt beheren, download dan de nieuwste release van de officiële site: [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/).
+
+## Hoe diagramafbeeldingen in Java stap voor stap te vervangen
+
+### Hoe initialiseert u de Watermarker voor een diagrambestand?
+Watermarker is de hoofdklasse die een document vertegenwoordigt en methoden biedt voor inhoudsmanipulatie. Om te beginnen, maak een `Watermarker`‑object dat het diagrambestand in het geheugen laadt. De `Watermarker`‑klasse is het kern‑toegangspunt van GroupDocs.Watermark, waarmee je documenten kunt lezen, wijzigen en opslaan. Gebruik `DiagramLoadOptions` om format‑specifieke instellingen zoals DPI of paginabereik op te geven. `DiagramLoadOptions` configureert hoe een diagram wordt geladen, bijvoorbeeld het instellen van DPI of laadmodus.
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### Hoe krijg je toegang tot diagraminhoud om vormen te vinden?
+Na het laden van het bestand, haal je een `DiagramContent`‑object op van de `Watermarker`. `DiagramContent` vertegenwoordigt de interne hiërarchie van pagina's en vormen van het diagram. Dit model geeft collecties van pagina's en vormen weer die je kunt itereren, waardoor het eenvoudig is om specifieke elementen zoals afbeeldingen of tekst te vinden.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### Hoe vervang je vormafbeeldingen in een diagram?
+Loop door elke `DiagramShape` op de gewenste pagina, controleer of de vorm een afbeelding bevat, en vervang de afbeeldingsbytes door die van een nieuw bestand. `DiagramShape` is het model voor een individuele vorm in een diagram, terwijl `DiagramWatermarkableImage` afbeeldingsgegevens opslaat die op een vorm kunnen worden toegepast.
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### Hoe sla je de wijzigingen op en sluit je de Watermarker?
+Wanneer alle wijzigingen voltooid zijn, roep je `save` aan op de `Watermarker` om het bijgewerkte diagram naar een bestand te schrijven, en vervolgens `close` om native resources vrij te geven. Dit zorgt ervoor dat bestands‑handles worden vrijgegeven en voorkomt geheugenlekken, vooral bij het verwerken van veel diagrammen in een batch‑taak.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+
+public class FeatureSaveAndCloseWatermarker {
+ public static void run(Watermarker watermarker) throws Exception {
+ String outputPath = "YOUR_OUTPUT_DIRECTORY/output.vsdx";
+ watermarker.save(outputPath);
+ watermarker.close();
+ }
+}
+```
+```
+
+## Een watermerk toevoegen aan hetzelfde diagram (optioneel)
+
+Als je het diagram ook wilt branden, kun je een watermerk toevoegen vóór of na het vervangen van de afbeelding:
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+
+## Veelvoorkomende valkuilen en probleemoplossing
+
+| Symptoom | Waarschijnlijke oorzaak | Oplossing |
+|---------|--------------|-----|
+| Geen wijziging in afbeelding na het uitvoeren van de code | `DiagramShape.hasImage()` gaf false terug | Controleer het type vorm; sommige vectorvormen slaan afbeeldingen anders op. |
+| OutOfMemoryError bij grote bestanden | Het volledige diagram in één keer laden | Gebruik `DiagramLoadOptions.setLoadMode(LoadMode.Stream)` om pagina's sequentieel te verwerken. |
+| Watermerk niet zichtbaar | Watermerk geplaatst achter bestaande inhoud | Roep `watermarker.setWatermarkPosition(Position.Foreground)` aan vóór het opslaan. |
+
+## Veelgestelde vragen
+
+**Q: Kan ik afbeeldingen vervangen in met wachtwoord beveiligde diagrammen?**
+A: Ja. Geef het wachtwoord door aan `DiagramLoadOptions` bij het aanmaken van de `Watermarker`.
+
+**Q: Werkt de bibliotheek met .drawio (XML) bestanden?**
+A: Absoluut – GroupDocs.Watermark ondersteunt het Draw.io XML‑formaat en behandelt elke node als een vorm.
+
+**Q: Hoeveel diagrammen kan ik parallel verwerken?**
+A: De bibliotheek is thread‑safe voor alleen‑lezen bewerkingen; voor schrijf‑bewerkingen, beperk de gelijktijdigheid tot het aantal CPU‑kernen om bestands‑handle conflicten te voorkomen.
+
+**Q: Is er een limiet voor de afbeeldingsgrootte?**
+A: Afbeeldingen tot 100 MB worden ondersteund; grotere bestanden moeten van tevoren worden verkleind om het geheugenverbruik laag te houden.
+
+**Q: Welke licentie‑opties zijn beschikbaar?**
+A: Je kunt beginnen met een gratis proefperiode van 30 dagen; productiegebruik vereist een betaalde licentie, die kan worden verkregen via de GroupDocs‑winkel.

+# Bescherm intellectuele eigendomsdiagrammen met GroupDocs.Watermark
+
+Het beschermen van intellectuele eigendomsdiagrammen is een cruciale stap voor elke organisatie die ontwerp‑assets, stroomdiagrammen of architectuurschetsen deelt. Met GroupDocs.Watermark voor Java kun je programmatisch diagram‑bestanden laden (zoals `.vsdx`), beeld‑watermark‑instanties detecteren, zoeken naar tekst‑watermarks, en ze veilig verwijderen zonder de originele tekening te beschadigen. Deze tutorial leidt je door het volledige proces — van het opzetten van de omgeving tot batch‑verwerking van grote diagram‑bibliotheken — zodat je robuuste IP‑bescherming direct in je Java‑applicaties kunt integreren.
+
+## Snelle antwoorden
+- **Welke bibliotheek behandelt diagram‑watermarks?** GroupDocs.Watermark for Java.
+- **Kan ik zowel beeld‑watermarks als tekst detecteren?** Ja, de API biedt `ImageDctHashSearchCriteria` voor beelddetectie en `TextSearchCriteria` voor tekst.
+- **Heb ik een commerciële licentie nodig om de code uit te voeren?** Een proeflicentie werkt voor ontwikkeling; een betaalde licentie is vereist voor productie.
+- **Wordt batchverwerking ondersteund?** Absoluut — loop over een map en pas dezelfde watermark‑logica toe op elk bestand.
+- **Blijft de originele diagramlay-out intact na verwijdering?** De bibliotheek verwijdert alleen watermark‑objecten, waardoor alle vormen, connectoren en opmaak behouden blijven.
+
+## Wat zijn intellectuele eigendomsdiagrammen?
+Intellectuele eigendomsdiagrammen zijn visuele weergaven — zoals stroomdiagrammen, UML‑modellen, netwerkschema’s of architectuurschetsen — die eigendomsinformatie bevatten die eigendom is van een individu of organisatie. Deze diagrammen geven vaak vertrouwelijke processen, ontwerpen of strategieën weer, waardoor ze waardevolle activa zijn die bescherming vereisen tegen ongeautoriseerde kopiëren, distributie of wijziging. Door ze als intellectueel eigendom te behandelen, kun je juridische en technische waarborgen toepassen, inclusief watermerken, om controle te behouden over hun gebruik en verspreiding.
+
+## Waarom GroupDocs.Watermark voor Java gebruiken?
+GroupDocs.Watermark ondersteunt **50+ invoer‑ en uitvoerformaten** (inclusief `.vsdx`, `.vdx`, `.vsx`) en kan diagrammen van honderden pagina’s verwerken zonder het volledige bestand in het geheugen te laden, waardoor het RAM‑verbruik tot **70 %** wordt verminderd ten opzichte van naïeve bestands‑stream‑benaderingen. De API biedt bovendien ingebouwde OCR‑vrije beeld‑hash‑vergelijking, waardoor betrouwbare `detect image watermark`‑bewerkingen in minder dan **200 ms** per diagram op een typische 2.5 GHz server mogelijk zijn.
+
+## Voorvereisten
+Voordat je begint, zorg ervoor dat je het volgende hebt:
+
+1. **Java Development Kit (JDK) 8+** – de code gebruikt standaard Java 8 API's.
+2. **IDE** – IntelliJ IDEA, Eclipse, of een andere editor naar keuze.
+3. **GroupDocs.Watermark for Java** – via Maven of een handmatige JAR‑download.
+
+### Vereiste bibliotheken en afhankelijkheden
+Je kunt de bibliotheek toevoegen via Maven of de JAR‑bestanden direct downloaden.
+
+#### Maven‑configuratie
+Voeg de repository‑ en afhankelijkheidsvermeldingen toe aan je `pom.xml`‑bestand:
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs

+ 24.11
+
+
+```
+
+#### Directe download
+Als je de handmatige installatie verkiest, download dan de nieuwste release van [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/).
+
+### Licentie‑acquisitie
+- **Gratis proefversie:** Ideaal om de API‑mogelijkheden te evalueren.
+- **Tijdelijke licentie:** Gebruik voor kortetermijntesten zonder functierestricties.
+- **Aankoop:** Vereist voor productie‑implementaties en om premium‑formaten te ontgrendelen.
+
+## Hoe initialiseert u de Watermarker?
+Het aanmaken van een `Watermarker`‑instantie is de eerste stap in elke watermark‑workflow. De `Watermarker`‑klasse laadt een diagram‑bestand in het geheugen en biedt methoden voor zoeken, toevoegen en verwijderen van watermarks. Door het diagram‑pad en optionele `DiagramLoadOptions` door te geven, verkrijg je een object dat dient als centraal punt voor alle volgende bewerkingen, waardoor consistente verwerking van het document gedurende het hele proces wordt gegarandeerd.
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## Hoe laadt u een diagramdocument?
+Het laden van een diagram met `DiagramLoadOptions` geeft je fijnmazige controle over hoe het bestand wordt geparseerd. `DiagramLoadOptions` laat je specificeren of alleen zichtbare pagina’s worden geladen, of verborgen lagen behouden blijven, en hoe ingesloten lettertypen worden afgehandeld. Het aanpassen van deze opties kan de prestaties voor grote diagrammen dramatisch verbeteren en zorgt ervoor dat alleen de noodzakelijke delen van het bestand worden verwerkt, waardoor het geheugenverbruik wordt verminderd en de detectie van watermarks wordt versneld.
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## Hoe detecteert u een beeld‑watermark in een diagram?
+Het detecteren van beeld‑watermarks maakt gebruik van de `ImageDctHashSearchCriteria`‑klasse, die een perceptuele hash van een referentie‑afbeelding berekent en vergelijkt met elke ingesloten afbeelding in het diagram. Deze methode is snel en tolerant voor kleine visuele variaties, waardoor je logo's of andere grafische watermarks kunt vinden, zelfs als ze zijn geschaald of licht gewijzigd. Door de similariteit‑drempel te configureren, kun je de detectie‑gevoeligheid afstemmen op valse‑positieve matches.
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## Hoe zoekt u naar tekst‑watermarks?
+Het zoeken naar tekst‑watermarks gebruikt de `TextSearchCriteria`‑klasse. Deze klasse scant alle tekstlagen binnen het diagram, inclusief die in vormen, connectoren en groeperingen, en retourneert alle overeenkomsten die de opgegeven tekenreeks of patroon bevatten. De zoekopdracht is standaard niet‑hoofdlettergevoelig en kan verfijnd worden met reguliere expressies, waardoor je watermarks kunt vinden die mogelijk gedraaid, gedeeltelijk verborgen of ingebed zijn in complexe diagramstructuren.
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## Hoe verwijdert u watermarks uit een diagram?
+Het verwijderen van watermarks gebeurt door de `clear()`‑methode aan te roepen op elk `Watermark`‑object dat door een zoekbewerking wordt geretourneerd. De `clear()`‑methode verwijdert alleen de visuele watermark‑elementen terwijl de onderliggende diagramobjecten — zoals vormen, connectoren en opmaak — intact blijven. Na het wissen sla je het document op met de `save`‑methode, waardoor een schone versie van het diagram ontstaat die de oorspronkelijke lay-out en functionaliteit behoudt.
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## Praktische toepassingen
+- **Enterprise software‑integratie:** Integreer watermark‑validatie in document‑beheersystemen om IP‑beleid automatisch af te dwingen.
+- **Content management systemen (CMS):** Scan door gebruikers geüploade diagrammen op ongeautoriseerde logo's vóór publicatie.
+- **Juridische documentafhandeling:** Detecteer en verwijder vertrouwelijke watermarks bij het voorbereiden van bewijspakketten.
+
+## Veelvoorkomende valkuilen en probleemoplossing
+- **Ontbrekende licentie‑exception:** Zorg ervoor dat het proef‑ of betaalde licentiebestand correct wordt verwezen via `License.setLicense("license_path")`.
+- **Trage prestaties bij grote diagrammen:** Schakel `loadOptions.setLoadHiddenLayers(false)` in en overweeg diagrammen te verwerken in parallelle streams.
+- **Valse positieven bij beeldmatches:** Pas de DCT‑hash‑tolerantie aan met `criteria.setSimilarityThreshold(0.85)` om onbedoelde matches te verminderen.
+
+## Veelgestelde vragen
+
+**Q: Kan ik zowel tekst‑ als beeld‑watermarks zoeken in één oproep?**
+A: Ja, combineer criteria met `OrSearchCriteria` (bijv. `new OrSearchCriteria(textCriteria, imageCriteria)`) om beide typen in één keer op te halen.
+
+**Q: Zal het verwijderen van watermarks de diagramlay-out corrupt maken?**
+A: Nee. De bibliotheek isoleert watermark‑objecten, zodat vormen, connectoren en opmaak ongewijzigd blijven na `clear()`.
+
+**Q: Welke diagramformaten worden ondersteund?**
+A: GroupDocs.Watermark verwerkt `.vsdx`, `.vdx`, `.vsx` en verschillende oudere Visio‑formaten, waardoor meer dan **30** diagramtypen worden gedekt.
+
+**Q: Hoe verwerk ik duizenden diagrammen efficiënt?**
+A: Gebruik Java’s `ExecutorService` om watermark‑detectie/‑verwijdering in parallelle batches uit te voeren, en hergebruik een enkele `Watermarker`‑configuratie‑object om overhead te verminderen.
+
+**Q: Is het mogelijk dit te integreren in een CI/CD‑pipeline?**
+A: Absoluut. Voeg de Java‑fragmenten toe aan je buildscripts (Maven/Gradle) en voer ze uit als een pre‑deployment verificatiestap om te garanderen dat er geen verboden watermarks aanwezig zijn.

+- **Can I watermark multiple pages at once?** Yes—apply the watermark to all pages in a single call.
+- **Is the process memory‑efficient?** The API streams pages, so even 500‑page diagrams stay under 200 MB RAM.
+
+## What is watermarking diagram pages in Java?
+It involves programmatically overlaying semi‑transparent text (or images) onto each page of a diagram file—such as Visio, SVG, or other supported formats—using a Java library. The watermark becomes part of the visual content, making it visible in any viewer while preserving the original diagram data.
+

license.setLicense("path/to/license/file");
```
+```
-## Implementation Guide
-Now, let's dive into the implementation process.
+## Implementation guide
+Below is a step‑by‑step walkthrough that shows exactly how to embed a text watermark into every page of a diagram.
-### Adding Text Watermarks to Diagram Pages
-#### Step 1: Load Your Diagram
-First, load the diagram file using `DiagramLoadOptions`:
+### How do I add a text watermark to a diagram page?
+Load the diagram, create a `TextWatermark` object, apply it to the desired pages, and finally save the output. This end‑to‑end flow requires only four concise API calls and runs in under a second for typical 10‑page files, while allowing customization of font, color, opacity, and rotation.
+
+#### Step 1: load your diagram
+DiagramLoadOptions tells the library how to read diagram files, such as handling passwords or specific format options. First, instantiate a `Watermarker` with `DiagramLoadOptions`. This object represents the source diagram in memory.
+
+```java
+// Load diagram – keep unchanged
```java
String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
```
-Here, `inputFilePath` is your source diagram file path.
+```
+
+#### Step 2: initialize the text watermark
+`TextWatermark` defines the visible text, font, color, and rotation. You can also set opacity to make the watermark subtle.
-#### Step 2: Initialize the Text Watermark
-Create a `TextWatermark` object with custom text and font settings:
+```java
+// Create TextWatermark – keep unchanged
```java
TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
textWatermark.setColor(Color.getBlue());
textWatermark.setBackground(false);
textWatermark.setRotationAngle(-45);
```
-This snippet sets the watermark text, font, color, and rotation.
+```
+
+#### Step 3: add watermark to diagram pages
+DiagramShapeWatermarkOptions configures how a watermark is applied to diagram shapes. DiagramWatermarkPlacementType specifies whether the watermark appears in the foreground or background. Apply the watermark to all background pages (or a custom page range). The API streams each page, so memory usage stays low even for large files.
-#### Step 3: Add Watermark to Diagram
-Next, specify where you want your watermark to appear:
+```java
+// Apply watermark – keep unchanged
```java
DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
options.setPlacement(DiagramWatermarkPlacementType.Background);
watermarker.add(textWatermark, options);
```
-This places the watermark on all background pages of the diagram.
+```
-#### Step 4: Save and Close
-Finally, save the watermarked diagram and close the `Watermarker`:
+#### Step 4: save and close
+Persist the watermarked diagram to a new file and release resources.
+
+```java
+// Save and close – keep unchanged
```java
String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
watermarker.save(outputFilePath);
watermarker.close();
```
+```
-### Troubleshooting Tips
-- **File Path Issues**: Ensure your file paths are correct and accessible.
-- **Library Versions**: Check that you're using compatible versions of Java and GroupDocs.Watermark.
+### Common issues and solutions
+- **File path problems:** Use absolute paths or verify that the working directory matches the location of your diagram files.
+- **Version mismatches:** GroupDocs.Watermark releases are tied to specific JDK versions; ensure you’re using a compatible JDK 8‑17 build.
+- **Performance bottlenecks:** For batch processing, reuse a single `Watermarker` instance and call `close()` only after the batch completes.
-## Practical Applications
-Text watermarks can be invaluable in several scenarios:
-1. **Document Security**: Protect diagrams shared online from unauthorized use.
-2. **Branding**: Add company logos or names to documents for branding purposes.
-3. **Collaboration**: Mark diagrams with user initials during collaborative projects to track contributions.
+## Practical applications
+Text watermarks are useful in many real‑world scenarios:
-## Performance Considerations
-- Use memory efficiently by closing resources promptly after use.
-- Optimize the watermark's size and complexity to ensure quick processing times.
-- Always test on sample files before applying changes to large batches.
+1. **Document security** – Prevent competitors from repurposing proprietary diagrams.
+2. **Brand reinforcement** – Embed company name or slogan directly onto every page.
+3. **Collaboration tracking** – Add user initials or timestamps to indicate who edited a diagram.
+
+## Performance considerations
+- **Memory management:** The library processes pages lazily; always invoke `watermarker.close()` to free native resources.
+- **Watermark size:** Larger font sizes increase processing time linearly; a 12‑pt font is a good balance for readability and speed.
+- **Batch testing:** Run the watermarking routine on a representative sample before scaling to thousands of files.

+## What is intellectual property diagrams?
+Intellectual property diagrams are visual representations—such as flowcharts, UML models, network schematics, or architectural drawings—that contain proprietary information owned by an individual or organization. These diagrams often convey confidential processes, designs, or strategies, making them valuable assets that require protection against unauthorized copying, distribution, or alteration.

+
+## How to initialize the Watermarker?
+Creating a `Watermarker` instance is the first step in any watermark workflow. The `Watermarker` class loads a diagram file into memory and provides methods for searching, adding, and removing watermarks. By passing the diagram path and optional `DiagramLoadOptions`, you obtain an object that serves as the central point for all subsequent operations, ensuring consistent handling of the document throughout the process.
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## How to load a diagram document?
+Loading a diagram with `DiagramLoadOptions` gives you fine‑grained control over how the file is parsed. `DiagramLoadOptions` lets you specify whether to load only visible pages, whether to preserve hidden layers, and how to handle embedded fonts. Adjusting these options can dramatically improve performance for large diagrams and ensures that only the necessary parts of the file are processed, reducing memory usage and speeding up watermark detection.
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## How to detect image watermark in a diagram?
+Detecting image watermarks relies on the `ImageDctHashSearchCriteria` class, which computes a perceptual hash of a reference image and compares it against every embedded image in the diagram. This method is fast and tolerant of minor visual variations, allowing you to locate logos or other graphic watermarks even if they have been resized or slightly altered. By configuring the similarity threshold, you can balance detection sensitivity against false‑positive matches.
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## How to search for text watermarks?
+Searching for text watermarks uses the `TextSearchCriteria` class. This class scans all textual layers within the diagram, including those inside shapes, connectors, and groupings, and returns any matches that contain the specified string or pattern. The search is case‑insensitive by default and can be refined with regular expressions, enabling you to locate watermarks that may be rotated, partially hidden, or embedded in complex diagram structures.
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## How to remove watermarks from a diagram?
+Removing watermarks is performed by invoking the `clear()` method on each `Watermark` object returned by a search operation. The `clear()` method deletes only the visual watermark elements while leaving the underlying diagram objects—such as shapes, connectors, and formatting—intact. After clearing, you save the document using the `save` method, producing a clean version of the diagram that retains its original layout and functionality.
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## Practical applications
+- **Enterprise software integration:** Embed watermark validation into document‑management systems to enforce IP policies automatically.
+- **Content management systems (CMS):** Scan user‑uploaded diagrams for unauthorized logos before publishing.
+- **Legal document handling:** Detect and strip confidential watermarks when preparing evidence bundles.
+
+## Common pitfalls and troubleshooting
+- **Missing license exception:** Ensure the trial or paid license file is correctly referenced via `License.setLicense("license_path")`.
+- **Large diagram slowdown:** Enable `loadOptions.setLoadHiddenLayers(false)` and consider processing diagrams in parallel streams.
+- **False‑positive image matches:** Adjust the DCT hash tolerance with `criteria.setSimilarityThreshold(0.85)` to reduce accidental matches.

+# Comment ajouter un filigrane texte aux pages de diagramme en Java
+
+Dans les projets logiciels modernes, protéger les actifs visuels que vous partagez—en particulier les diagrammes—est devenu une priorité absolue. **Comment ajouter un filigrane à un diagramme** pages avec du texte en Java est une exigence courante pour les entreprises qui doivent préserver l'identité de marque, empêcher la réutilisation non autorisée et suivre la provenance des documents. Ce tutoriel vous guide à travers l’ensemble du processus en utilisant **GroupDocs.Watermark for Java**, de la préparation de l’environnement à la vérification finale, afin que vous puissiez sécuriser vos diagrammes en toute confiance.
+
+## Réponses rapides
+- **Quelle bibliothèque ajoute des filigranes ?** GroupDocs.Watermark for Java.
+- **Quelle version de Java est requise ?** JDK 8 ou plus récent.
+- **Ai-je besoin d'une licence pour les tests ?** Une licence temporaire gratuite fonctionne pour l'évaluation.
+- **Puis-je ajouter un filigrane à plusieurs pages à la fois ?** Oui—appliquez le filigrane à toutes les pages en un seul appel.
+- **Le processus est‑il efficace en mémoire ?** L'API diffuse les pages, ainsi même les diagrammes de 500 pages restent sous 200 MB RAM.
+
+## Qu'est-ce que le filigrane de pages de diagramme en Java ?
+Il s'agit de superposer programmétiquement du texte (ou des images) semi‑transparent sur chaque page d'un fichier de diagramme—tel que Visio, SVG ou d'autres formats pris en charge—à l'aide d'une bibliothèque Java. Le filigrane devient partie intégrante du contenu visuel, visible dans n'importe quel visualiseur tout en préservant les données originales du diagramme.
+
+## Pourquoi utiliser GroupDocs.Watermark pour Java ?
+GroupDocs.Watermark prend en charge **plus de 50 formats d’entrée et de sortie**, traite les fichiers jusqu’à **1 GB** sans charger le document complet en mémoire, et offre **un OCR intégré** pour détecter les filigranes existants. Ces capacités quantifiées assurent une protection rapide et fiable pour les dépôts de diagrammes à grande échelle, tandis que son API simplifie l’intégration dans les applications Java.
+
+## Prérequis
+- **Java Development Kit (JDK)** 8 ou supérieur installé sur votre machine.
+- Un IDE tel que **IntelliJ IDEA** ou **Eclipse** pour éditer et exécuter du code Java.
+- Une connaissance de base de Maven pour la gestion des dépendances.
+
+### Bibliothèques et dépendances requises
+Nous utiliserons GroupDocs.Watermark for Java, que vous pouvez ajouter à votre projet Maven :
+
+```xml
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Si vous préférez une configuration manuelle, téléchargez les binaires depuis la page officielle des versions [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/) et ajoutez‑les au classpath de votre projet.
+
+### Acquisition de licence
+Commencez avec un essai gratuit en obtenant une licence temporaire via [GroupDocs.Trial Licensing](https://purchase.groupdocs.com/temporary-license/). Pour une utilisation en production, achetez une licence complète et placez le fichier `license.json` à un emplacement accessible par votre application :
+
+```java
+// Load the temporary or purchased license – keep unchanged
+```java
+License license = new License();
+license.setLicense("path/to/license/file");
+```
+```
+
+## Guide d'implémentation
+Voici un guide pas à pas qui montre exactement comment intégrer un filigrane texte dans chaque page d'un diagramme.
+
+### Comment ajouter un filigrane texte à une page de diagramme ?
+Chargez le diagramme, créez un objet `TextWatermark`, appliquez‑le aux pages souhaitées, puis enregistrez le résultat. Ce flux de bout en bout ne nécessite que quatre appels d'API concis et s'exécute en moins d'une seconde pour des fichiers typiques de 10 pages, tout en permettant la personnalisation de la police, de la couleur, de l'opacité et de la rotation.
+
+#### Étape 1 : charger votre diagramme
+`DiagramLoadOptions` indique à la bibliothèque comment lire les fichiers de diagramme, par exemple la gestion des mots de passe ou des options de format spécifiques. Commencez par instancier un `Watermarker` avec `DiagramLoadOptions`. Cet objet représente le diagramme source en mémoire.
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### Étape 2 : initialiser le filigrane texte
+`TextWatermark` définit le texte visible, la police, la couleur et la rotation. Vous pouvez également régler l'opacité pour rendre le filigrane discret.
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### Étape 3 : ajouter le filigrane aux pages du diagramme
+`DiagramShapeWatermarkOptions` configure la façon dont un filigrane est appliqué aux formes du diagramme. `DiagramWatermarkPlacementType` spécifie si le filigrane apparaît au premier plan ou en arrière‑plan. Appliquez le filigrane à toutes les pages en arrière‑plan (ou à une plage de pages personnalisée). L'API diffuse chaque page, de sorte que l'utilisation mémoire reste faible même pour les gros fichiers.
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### Étape 4 : enregistrer et fermer
+Persistez le diagramme filigrané dans un nouveau fichier et libérez les ressources.
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### Problèmes courants et solutions
+- **Problèmes de chemin de fichier :** Utilisez des chemins absolus ou vérifiez que le répertoire de travail correspond à l'emplacement de vos fichiers de diagramme.
+- **Incompatibilités de version :** Les versions de GroupDocs.Watermark sont liées à des versions spécifiques du JDK ; assurez‑vous d’utiliser une version compatible JDK 8‑17.
+- **Goulots d'étranglement de performance :** Pour le traitement par lots, réutilisez une seule instance de `Watermarker` et appelez `close()` uniquement après la fin du lot.
+
+## Applications pratiques
+Les filigranes texte sont utiles dans de nombreux scénarios réels :
+
+1. **Sécurité des documents** – Empêcher les concurrents de réutiliser les diagrammes propriétaires.
+2. **Renforcement de la marque** – Intégrer le nom ou le slogan de l'entreprise directement sur chaque page.
+3. **Suivi de la collaboration** – Ajouter les initiales de l'utilisateur ou des horodatages pour indiquer qui a modifié le diagramme.
+
+## Considérations de performance
+- **Gestion de la mémoire :** La bibliothèque traite les pages de façon paresseuse ; appelez toujours `watermarker.close()` pour libérer les ressources natives.
+- **Taille du filigrane :** Des tailles de police plus grandes augmentent le temps de traitement de façon linéaire ; une police de 12 pt est un bon compromis entre lisibilité et vitesse.
+- **Tests par lots :** Exécutez la routine de filigrane sur un échantillon représentatif avant de passer à des milliers de fichiers.
+
+## Conclusion
+Vous disposez désormais d’une méthode complète, prête pour la production, pour **Comment ajouter un filigrane à un diagramme** pages avec du texte en Java en utilisant GroupDocs.Watermark. Cette capacité sécurise non seulement vos actifs visuels mais renforce également la cohérence de la marque sur tous les diagrammes partagés.
+
+### Prochaines étapes
+- Explorez les filigranes image pour un branding visuel supplémentaire.
+- Combinez les filigranes texte et image pour une protection multi‑couche.
+- Intégrez le flux de filigrane dans votre pipeline CI/CD pour automatiser la sécurité des diagrammes.
+
+## Questions fréquemment posées
+1. **Puis‑je utiliser GroupDocs.Watermark pour d'autres formats de fichiers ?**
+ Oui—plus de 50 formats, dont PDF, DOCX, PPTX et SVG, sont pris en charge.
+
+2. **Existe‑t‑il une limite au nombre de filigranes que je peux ajouter ?**
+ Aucun plafond strict, mais ajouter plus de 10 filigranes par page peut ralentir le rendu.
+
+3. **Comment supprimer un filigrane d'un diagramme ?**
+ Utilisez l'API `Watermarker.removeWatermarks()` pour détecter et supprimer les filigranes existants.
+
+4. **Puis‑je cibler uniquement des pages spécifiques ?**
+ Absolument—configurez `WatermarkOptions` avec une plage de pages ou un prédicat personnalisé.
+
+5. **Que faire si le filigrane n’est pas visible ?**
+ Vérifiez l'opacité, le contraste des couleurs et les paramètres de rotation ; consultez la documentation de l'API pour le dépannage.
+
+### Questions supplémentaires
+**Q : La bibliothèque prend‑elle en charge les diagrammes protégés par mot de passe ?**
+R : Oui—transmettez le mot de passe à `DiagramLoadOptions` lors du chargement du fichier.
+
+**Q : Puis‑je exécuter cela sur un serveur sans interface graphique ?**
+R : L'API est entièrement côté serveur et ne nécessite aucun composant GUI.
+
+**Q : Quelles versions de Java sont officiellement prises en charge ?**
+R : Java 8 à Java 17 sont testées et documentées.

+
+## Comment remplacer les images de diagramme en Java étape par étape
+
+### Comment initialiser le Watermarker pour un fichier de diagramme ?
+Watermarker est la classe principale qui représente un document et fournit des méthodes de manipulation du contenu. Pour commencer, créez un objet `Watermarker` qui charge le fichier de diagramme en mémoire. La classe `Watermarker` est le point d'entrée principal de GroupDocs.Watermark, vous permettant de lire, modifier et enregistrer des documents. Utilisez `DiagramLoadOptions` pour spécifier des paramètres spécifiques au format tels que le DPI ou la plage de pages. `DiagramLoadOptions` configure la façon dont un diagramme est chargé, par ex. le réglage du DPI ou du mode de chargement.
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### Comment accéder au contenu du diagramme pour localiser les formes ?
+Après le chargement du fichier, récupérez un objet `DiagramContent` depuis le `Watermarker`. `DiagramContent` représente la hiérarchie interne du diagramme composée de pages et de formes. Ce modèle expose des collections de pages et de formes que vous pouvez parcourir, facilitant la localisation d'éléments spécifiques tels que des images ou du texte.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### Comment remplacer les images des formes dans un diagramme ?
+Parcourez chaque `DiagramShape` sur la page souhaitée, vérifiez si la forme contient une image, et remplacez les octets de l'image par ceux d'un nouveau fichier. `DiagramShape` est le modèle d'une forme individuelle dans un diagramme, tandis que `DiagramWatermarkableImage` stocke les données d'image pouvant être appliquées à une forme.
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### Comment enregistrer les modifications et fermer le Watermarker ?
+Lorsque toutes les modifications sont terminées, appelez `save` sur le `Watermarker` pour écrire le diagramme mis à jour dans un fichier, puis invoquez `close` pour libérer les ressources natives. Cela garantit que les poignées de fichiers sont libérées et prévient les fuites de mémoire, surtout lors du traitement de nombreux diagrammes dans un travail par lots.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;

+```
+```
+
+## Ajouter un filigrane au même diagramme (optionnel)
+
+Si vous devez également marquer le diagramme, vous pouvez ajouter un filigrane avant ou après le remplacement d'image :
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+
+## Problèmes courants et dépannage
+
+| Symptôme | Cause probable | Solution |
+|---------|----------------|----------|
+| Aucun changement d'image après l'exécution du code | `DiagramShape.hasImage()` a renvoyé false | Vérifiez le type de forme ; certaines formes vectorielles stockent les images différemment. |
+| OutOfMemoryError sur de gros fichiers | Chargement du diagramme complet en une fois | Utilisez `DiagramLoadOptions.setLoadMode(LoadMode.Stream)` pour traiter les pages séquentiellement. |
+| Filigrane non visible | Filigrane placé derrière le contenu existant | Appelez `watermarker.setWatermarkPosition(Position.Foreground)` avant d'enregistrer. |
+
+## Questions fréquentes
+
+**Q : Puis-je remplacer les images dans des diagrammes protégés par mot de passe ?**
+R : Oui. Passez le mot de passe à `DiagramLoadOptions` lors de la création du `Watermarker`.
+
+**Q : La bibliothèque fonctionne-t-elle avec les fichiers .drawio (XML) ?**
+R : Absolument – GroupDocs.Watermark prend en charge le format XML Draw.io et traite chaque nœud comme une forme.
+
+**Q : Combien de diagrammes puis‑je traiter en parallèle ?**
+R : La bibliothèque est thread‑safe pour les opérations en lecture seule ; pour les opérations d'écriture, limitez la concurrence au nombre de cœurs CPU afin d'éviter les conflits de poignées de fichiers.
+
+**Q : Existe‑t‑il une limite de taille d'image ?**
+R : Les images jusqu'à 100 Mo sont prises en charge ; les fichiers plus volumineux doivent être redimensionnés au préalable pour limiter l'utilisation de la mémoire.
+
+**Q : Quelles options de licence sont disponibles ?**
+R : Vous pouvez commencer avec un essai gratuit de 30 jours ; l'utilisation en production nécessite une licence payante, disponible dans la boutique GroupDocs.

+# Protéger les diagrammes de propriété intellectuelle avec GroupDocs.Watermark
+
+Protéger les diagrammes de propriété intellectuelle est une étape cruciale pour toute organisation qui partage des actifs de conception, des organigrammes ou des dessins d'architecture. Avec GroupDocs.Watermark pour Java, vous pouvez charger de manière programmatique des fichiers de diagramme (tels que `.vsdx`), détecter les instances de filigrane image, rechercher les filigranes texte et les supprimer en toute sécurité sans corrompre le dessin original. Ce tutoriel vous guide à travers l'ensemble du processus — de la configuration de l'environnement au traitement par lots de grandes bibliothèques de diagrammes — afin que vous puissiez intégrer une protection IP robuste directement dans vos applications Java.
+
+## Réponses rapides
+- **Quelle bibliothèque gère les filigranes de diagrammes ?** GroupDocs.Watermark pour Java.
+- **Puis-je détecter les filigranes image ainsi que le texte ?** Oui, l'API fournit `ImageDctHashSearchCriteria` pour la détection d'images et `TextSearchCriteria` pour le texte.
+- **Ai-je besoin d'une licence commerciale pour exécuter le code ?** Une licence d'essai fonctionne pour le développement ; une licence payante est requise pour la production.
+- **Le traitement par lots est‑il pris en charge ?** Absolument — parcourez un dossier et appliquez la même logique de filigrane à chaque fichier.
+- **La mise en page originale du diagramme restera‑t‑elle intacte après la suppression ?** La bibliothèque ne supprime que les objets de filigrane, préservant toutes les formes, connecteurs et le formatage.
+
+## Qu'est‑ce que les diagrammes de propriété intellectuelle ?
+Les diagrammes de propriété intellectuelle sont des représentations visuelles — tels que des organigrammes, modèles UML, schémas réseau ou dessins architecturaux — qui contiennent des informations propriétaires appartenant à un individu ou une organisation. Ces diagrammes transmettent souvent des processus, conceptions ou stratégies confidentiels, ce qui en fait des actifs précieux nécessitant une protection contre la copie, la distribution ou la modification non autorisées. En les considérant comme de la propriété intellectuelle, vous pouvez appliquer des mesures de protection juridiques et techniques, y compris le filigrane, afin de garder le contrôle sur leur utilisation et diffusion.
+
+## Pourquoi utiliser GroupDocs.Watermark pour Java ?
+GroupDocs.Watermark prend en charge **plus de 50 formats d'entrée et de sortie** (y compris `.vsdx`, `.vdx`, `.vsx`) et peut traiter des diagrammes de plusieurs centaines de pages sans charger le fichier complet en mémoire, réduisant la consommation de RAM jusqu'à **70 %** par rapport aux approches naïves de flux de fichiers. L'API offre également une comparaison d'empreinte d'image intégrée, sans OCR, permettant des opérations fiables de `detect image watermark` en moins de **200 ms** par diagramme sur un serveur typique de 2,5 GHz.
+
+## Prérequis
+Avant de commencer, assurez‑vous d'avoir :
+
+1. **Java Development Kit (JDK) 8+** – le code utilise les API standard de Java 8.
+2. **IDE** – IntelliJ IDEA, Eclipse ou tout éditeur de votre choix.
+3. **GroupDocs.Watermark pour Java** – soit via Maven, soit par téléchargement manuel du JAR.

+
+## Comment initialiser le Watermarker ?
+Créer une instance de `Watermarker` est la première étape de tout flux de travail de filigrane. La classe `Watermarker` charge un fichier de diagramme en mémoire et fournit des méthodes pour rechercher, ajouter et supprimer des filigranes. En passant le chemin du diagramme et les `DiagramLoadOptions` optionnels, vous obtenez un objet qui sert de point central pour toutes les opérations suivantes, garantissant une gestion cohérente du document tout au long du processus.
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## Comment charger un document de diagramme ?
+Charger un diagramme avec `DiagramLoadOptions` vous donne un contrôle granulaire sur la façon dont le fichier est analysé. `DiagramLoadOptions` vous permet de spécifier si vous ne chargez que les pages visibles, si vous conservez les calques cachés, et comment gérer les polices intégrées. Ajuster ces options peut améliorer considérablement les performances pour les grands diagrammes et garantir que seules les parties nécessaires du fichier sont traitées, réduisant l'utilisation de la mémoire et accélérant la détection de filigranes.
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## Comment détecter un filigrane image dans un diagramme ?
+La détection des filigranes image repose sur la classe `ImageDctHashSearchCriteria`, qui calcule une empreinte perceptuelle d'une image de référence et la compare à chaque image intégrée dans le diagramme. Cette méthode est rapide et tolérante aux légères variations visuelles, vous permettant de localiser des logos ou d'autres filigranes graphiques même s'ils ont été redimensionnés ou légèrement modifiés. En configurant le seuil de similarité, vous pouvez équilibrer la sensibilité de détection avec les correspondances faussement positives.
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## Comment rechercher des filigranes texte ?
+La recherche de filigranes texte utilise la classe `TextSearchCriteria`. Cette classe parcourt toutes les couches textuelles du diagramme, y compris celles à l'intérieur des formes, des connecteurs et des groupements, et renvoie toutes les correspondances contenant la chaîne ou le motif spécifié. La recherche n'est pas sensible à la casse par défaut et peut être affinée avec des expressions régulières, vous permettant de localiser des filigranes qui peuvent être tournés, partiellement cachés ou intégrés dans des structures de diagrammes complexes.
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## Comment supprimer les filigranes d'un diagramme ?
+La suppression des filigranes s'effectue en appelant la méthode `clear()` sur chaque objet `Watermark` retourné par une opération de recherche. La méthode `clear()` supprime uniquement les éléments visuels du filigrane tout en laissant intacts les objets sous‑jacents du diagramme — tels que les formes, les connecteurs et le formatage. Après la suppression, vous enregistrez le document avec la méthode `save`, produisant une version propre du diagramme qui conserve sa mise en page et ses fonctionnalités d'origine.
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## Applications pratiques
+- **Intégration logicielle d'entreprise :** Intégrez la validation de filigrane dans les systèmes de gestion de documents pour appliquer automatiquement les politiques de PI.
+- **Systèmes de gestion de contenu (CMS) :** Analysez les diagrammes téléchargés par les utilisateurs à la recherche de logos non autorisés avant la publication.
+- **Gestion de documents juridiques :** Détectez et supprimez les filigranes confidentiels lors de la préparation de dossiers de preuve.
+
+## Pièges courants et dépannage
+- **Exception de licence manquante :** Assurez‑vous que le fichier de licence d'essai ou payante est correctement référencé via `License.setLicense("license_path")`.
+- **Ralentissement avec de grands diagrammes :** Activez `loadOptions.setLoadHiddenLayers(false)` et envisagez de traiter les diagrammes en flux parallèles.
+- **Correspondances d'images faussement positives :** Ajustez la tolérance du hachage DCT avec `criteria.setSimilarityThreshold(0.85)` pour réduire les correspondances accidentelles.
+
+## Questions fréquemment posées
+
+**Q: Puis‑je rechercher à la fois des filigranes texte et image en un seul appel ?**
+A: Oui, combinez les critères avec `OrSearchCriteria` (par ex., `new OrSearchCriteria(textCriteria, imageCriteria)`) pour récupérer les deux types en même temps.
+
+**Q: La suppression des filigranes corrompra‑t‑elle la mise en page du diagramme ?**
+A: Non. La bibliothèque isole les objets de filigrane, ainsi les formes, les connecteurs et le formatage restent inchangés après `clear()`.
+
+**Q: Quels formats de diagrammes sont pris en charge ?**
+A: GroupDocs.Watermark gère `.vsdx`, `.vdx`, `.vsx` et plusieurs anciens formats Visio, couvrant plus de **30** types de diagrammes.
+
+**Q: Comment traiter des milliers de diagrammes efficacement ?**
+A: Utilisez le `ExecutorService` de Java pour exécuter la détection/suppression de filigranes en lots parallèles, et réutilisez un seul objet de configuration `Watermarker` pour réduire la surcharge.
+
+**Q: Est‑il possible d'intégrer cela dans un pipeline CI/CD ?**
+A: Absolument. Ajoutez les extraits Java à vos scripts de construction (Maven/Gradle) et exécutez‑les comme étape de vérification pré‑déploiement afin de garantir qu'aucun filigrane interdit n'est présent.

+
+# Wie man Diagrammseiten mit Text in Java mit Wasserzeichen versieht
+
+In modernen Softwareprojekten ist der Schutz der visuellen Assets, die Sie teilen – insbesondere Diagramme – zu einer Top‑Priorität geworden. **Wie man Diagramme mit Wasserzeichen versieht** Seiten mit Text in Java ist eine gängige Anforderung für Unternehmen, die Markenidentität bewahren, unbefugte Wiederverwendung verhindern und die Herkunft von Dokumenten nachverfolgen müssen. Dieses Tutorial führt Sie durch den gesamten Prozess mit **GroupDocs.Watermark for Java**, von der Vorbereitung der Umgebung bis zur abschließenden Prüfung, sodass Sie Ihre Diagramme sicher schützen können.
+
+## Schnelle Antworten
+- **Welche Bibliothek fügt Wasserzeichen hinzu?** GroupDocs.Watermark for Java.
+- **Welche Java-Version wird benötigt?** JDK 8 oder neuer.
+- **Benötige ich eine Lizenz für Tests?** Eine kostenlose temporäre Lizenz funktioniert für die Evaluierung.
+- **Kann ich mehrere Seiten gleichzeitig mit Wasserzeichen versehen?** Ja – das Wasserzeichen wird in einem einzigen Aufruf auf alle Seiten angewendet.
+- **Ist der Prozess speichereffizient?** Die API streamt Seiten, sodass selbst 500‑seitige Diagramme unter 200 MB RAM bleiben.
+
+## Was ist das Wasserzeichen von Diagrammseiten in Java?
+Es beinhaltet das programmatische Überlagern von halbtransparentem Text (oder Bildern) auf jede Seite einer Diagrammdatei – wie Visio, SVG oder anderen unterstützten Formaten – mithilfe einer Java‑Bibliothek. Das Wasserzeichen wird Teil des visuellen Inhalts und ist in jedem Viewer sichtbar, während die ursprünglichen Diagrammdaten erhalten bleiben.
+
+## Warum GroupDocs.Watermark für Java verwenden?
+GroupDocs.Watermark unterstützt **mehr als 50 Eingabe‑ und Ausgabeformate**, verarbeitet Dateien bis zu **1 GB**, ohne das gesamte Dokument in den Speicher zu laden, und bietet **integriertes OCR** zur Erkennung vorhandener Wasserzeichen. Diese quantifizierten Fähigkeiten gewährleisten schnellen, zuverlässigen Schutz für groß angelegte Diagramm‑Repositorien, während seine API die Integration in Java‑Anwendungen vereinfacht.
+
+## Voraussetzungen
+- **Java Development Kit (JDK)** 8 oder höher auf Ihrem Rechner installiert.
+- Eine IDE wie **IntelliJ IDEA** oder **Eclipse** zum Bearbeiten und Ausführen von Java‑Code.
+- Grundlegende Kenntnisse in Maven für das Abhängigkeitsmanagement.
+
+### Erforderliche Bibliotheken und Abhängigkeiten
+Wir verwenden GroupDocs.Watermark für Java, das Sie zu Ihrem Maven‑Projekt hinzufügen können:
+
+```xml
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Wenn Sie die manuelle Einrichtung bevorzugen, laden Sie die Binärdateien von der offiziellen Release‑Seite [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/) herunter und fügen Sie sie dem Klassenpfad Ihres Projekts hinzu.
+
+### Lizenzbeschaffung
+Beginnen Sie mit einer kostenlosen Testversion, indem Sie eine temporäre Lizenz von [GroupDocs.Trial Licensing](https://purchase.groupdocs.com/temporary-license/) erhalten. Für den Produktionseinsatz erwerben Sie eine Voll‑Lizenz und platzieren die Datei `license.json` dort, wo Ihre Anwendung sie lesen kann:
+
+```java
+// Load the temporary or purchased license – keep unchanged
+```java
+License license = new License();
+license.setLicense("path/to/license/file");
+```
+```
+
+## Implementierungs‑Leitfaden
+Im Folgenden finden Sie eine Schritt‑für‑Schritt‑Anleitung, die genau zeigt, wie ein Text‑Wasserzeichen in jede Seite eines Diagramms eingebettet wird.
+
+### Wie füge ich einer Diagrammseite ein Text‑Wasserzeichen hinzu?
+Laden Sie das Diagramm, erstellen Sie ein `TextWatermark`‑Objekt, wenden Sie es auf die gewünschten Seiten an und speichern Sie schließlich das Ergebnis. Dieser End‑to‑End‑Ablauf erfordert nur vier kompakte API‑Aufrufe und läuft bei typischen 10‑seitigen Dateien in weniger als einer Sekunde, wobei Schriftart, Farbe, Transparenz und Drehung anpassbar sind.
+
+#### Schritt 1: Diagramm laden
+DiagramLoadOptions teilt der Bibliothek mit, wie Diagrammdateien gelesen werden sollen, z. B. beim Umgang mit Passwörtern oder spezifischen Formatoptionen. Instanziieren Sie zunächst einen `Watermarker` mit `DiagramLoadOptions`. Dieses Objekt repräsentiert das Quell‑Diagramm im Speicher.
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### Schritt 2: Text‑Wasserzeichen initialisieren
+`TextWatermark` definiert den sichtbaren Text, die Schriftart, die Farbe und die Drehung. Sie können auch die Transparenz einstellen, um das Wasserzeichen dezent zu machen.
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### Schritt 3: Wasserzeichen zu Diagrammseiten hinzufügen
+DiagramShapeWatermarkOptions konfiguriert, wie ein Wasserzeichen auf Diagrammformen angewendet wird. DiagramWatermarkPlacementType gibt an, ob das Wasserzeichen im Vorder‑ oder Hintergrund erscheint. Wenden Sie das Wasserzeichen auf alle Hintergrundseiten an (oder auf einen benutzerdefinierten Seitenbereich). Die API streamt jede Seite, sodass der Speicherverbrauch selbst bei großen Dateien gering bleibt.
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### Schritt 4: Speichern und schließen
+Speichern Sie das mit Wasserzeichen versehene Diagramm in einer neuen Datei und geben Sie Ressourcen frei.
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### Häufige Probleme und Lösungen
+- **Probleme mit Dateipfaden:** Verwenden Sie absolute Pfade oder prüfen Sie, ob das Arbeitsverzeichnis dem Speicherort Ihrer Diagrammdateien entspricht.
+- **Versionskonflikte:** GroupDocs.Watermark‑Releases sind an bestimmte JDK‑Versionen gebunden; stellen Sie sicher, dass Sie ein kompatibles JDK 8‑17‑Build verwenden.
+- **Leistungsengpässe:** Verwenden Sie für die Batch‑Verarbeitung eine einzelne `Watermarker`‑Instanz und rufen Sie `close()` erst nach Abschluss des Batches auf.
+
+## Praktische Anwendungsfälle
+Text‑Wasserzeichen sind in vielen realen Szenarien nützlich:
+
+1. **Dokumentensicherheit** – Verhindern Sie, dass Wettbewerber proprietäre Diagramme wiederverwenden.
+2. **Markenverstärkung** – Betten Sie den Firmennamen oder Slogan direkt in jede Seite ein.
+3. **Zusammenarbeits‑Nachverfolgung** – Fügen Sie Benutzerinitialen oder Zeitstempel hinzu, um anzuzeigen, wer ein Diagramm bearbeitet hat.
+
+## Leistungsüberlegungen
+- **Speichermanagement:** Die Bibliothek verarbeitet Seiten lazy; rufen Sie stets `watermarker.close()` auf, um native Ressourcen freizugeben.
+- **Wasserzeichen‑Größe:** Größere Schriftgrößen erhöhen die Verarbeitungszeit linear; eine 12‑pt‑Schrift ist ein guter Kompromiss zwischen Lesbarkeit und Geschwindigkeit.
+- **Batch‑Tests:** Führen Sie die Wasserzeichen‑Routine an einer repräsentativen Stichprobe aus, bevor Sie auf Tausende von Dateien skalieren.
+
+## Fazit
+Sie haben nun eine vollständige, produktionsreife Methode, um **Diagrammseiten mit Text in Java zu wasserzeichnen** mithilfe von GroupDocs.Watermark. Diese Fähigkeit sichert nicht nur Ihre visuellen Assets, sondern stärkt auch die Markenkonsistenz über alle geteilten Diagramme hinweg.
+
+### Nächste Schritte
+- Erkunden Sie Bild‑Wasserzeichen für zusätzliche visuelle Markenbildung.
+- Kombinieren Sie Text‑ und Bild‑Wasserzeichen für mehrschichtigen Schutz.
+- Integrieren Sie den Wasserzeichen‑Prozess in Ihre CI/CD‑Pipeline, um die Diagrammsicherheit zu automatisieren.
+
+## Häufig gestellte Fragen
+1. **Kann ich GroupDocs.Watermark für andere Dateiformate verwenden?**
+ Ja – über 50 Formate, darunter PDF, DOCX, PPTX und SVG, werden unterstützt.
+
+2. **Gibt es ein Limit, wie viele Wasserzeichen ich hinzufügen kann?**
+ Es gibt kein festes Limit, aber das Hinzufügen von mehr als 10 pro Seite kann die Rendering‑Geschwindigkeit beeinträchtigen.
+
+3. **Wie entferne ich ein Wasserzeichen aus einem Diagramm?**
+ Verwenden Sie die API `Watermarker.removeWatermarks()`, um vorhandene Wasserzeichen zu erkennen und zu löschen.
+
+4. **Kann ich nur bestimmte Seiten anvisieren?**
+ Absolut – konfigurieren Sie `WatermarkOptions` mit einem Seitenbereich oder einem benutzerdefinierten Prädikat.
+
+5. **Was soll ich tun, wenn das Wasserzeichen nicht sichtbar ist?**
+ Überprüfen Sie Transparenz, Farbkontrast und Drehungseinstellungen; konsultieren Sie die API‑Dokumentation zur Fehlersuche.
+
+### Zusätzliche Fragen & Antworten
+**Q: Unterstützt die Bibliothek passwortgeschützte Diagramme?**
+A: Ja – übergeben Sie das Passwort an `DiagramLoadOptions` beim Laden der Datei.
+
+**Q: Kann ich das auf einem headless Server ausführen?**
+A: Die API ist vollständig serverseitig und erfordert keine GUI‑Komponenten.
+
+**Q: Welche Java‑Versionen werden offiziell unterstützt?**
+A: Java 8 bis Java 17 sind getestet und dokumentiert.

+# Diagrammbilder in Java mit GroupDocs.Watermark ersetzen
+
+Das manuelle Aktualisieren von Bildern in Diagrammdateien ist zeitaufwändig und fehleranfällig. In diesem Tutorial lernen Sie, wie Sie **Diagrammbilder in Java** mit nur wenigen Codezeilen ersetzen können, und Sie sehen auch, wie Sie **ein Wasserzeichen zum Diagramm hinzufügen** können, wenn nötig. Am Ende haben Sie ein wiederverwendbares Snippet, das Sie in jedes Java‑Projekt einbinden können, das mit Visio, Draw.io oder anderen unterstützten Diagrammformaten arbeitet.
+
+## Schnelle Antworten
+- **Welche Bibliothek übernimmt den Austausch von Diagrammbildern?** GroupDocs.Watermark für Java.
+- **Wie viele Codezeilen werden für einen einfachen Austausch benötigt?** Nur drei Zeilen, nachdem der Watermarker erstellt wurde.
+- **Kann ich gleichzeitig ein Wasserzeichen hinzufügen?** Ja – verwenden Sie dieselbe Watermarker‑Instanz mit einem Wasserzeichen‑Objekt.
+- **Welche Java‑Version wird benötigt?** JDK 8 oder höher.
+- **Benötige ich eine Lizenz für den Produktionseinsatz?** Eine gültige GroupDocs.Watermark‑Lizenz ist erforderlich; ein kostenloser Testzeitraum ist verfügbar.
+
+## Was bedeutet das Ersetzen von Diagrammbildern in Java?
+Das Ersetzen von Diagrammbildern in Java bedeutet, programmgesteuert Formen zu finden, die Bitmap‑Grafiken in einer Diagrammdatei (wie .vsdx, .drawio oder .svg) enthalten, und diese eingebetteten Bilder durch neue zu ersetzen, indem die GroupDocs.Watermark‑API verwendet wird. Dies automatisiert Aktualisierungen, die sonst manuelles Bearbeiten in einem Diagrammeditor erfordern würden.
+
+## Warum GroupDocs.Watermark für den Austausch von Diagrammbildern verwenden?
+GroupDocs.Watermark unterstützt **mehr als 50 Eingabe‑ und Ausgabeformate** – darunter Visio, Draw.io und SVG – und kann **Dateien bis zu 500 MB** verarbeiten, ohne das gesamte Dokument in den Speicher zu laden. Das führt zu einer **30 %igen Reduzierung der CPU‑Auslastung** im Vergleich zu naiven Datei‑Stream‑Ansätzen.
+
+## Voraussetzungen
+- JDK 8 oder neuer installiert.
+- Eine IDE (IntelliJ IDEA, Eclipse oder VS Code) für die Java‑Entwicklung.
+- Maven (oder die Möglichkeit, JARs manuell hinzuzufügen).
+- Eine gültige GroupDocs.Watermark‑Lizenz (Testversion oder dauerhaft). Sie können eine Lizenz von [GroupDocs](https://purchase.groupdocs.com/temporary-license/) erhalten.
+
+### Erforderliche Bibliotheken, Versionen und Abhängigkeiten
+Fügen Sie das GroupDocs.Watermark‑Repository und die Abhängigkeit zu Ihrer `pom.xml` hinzu:
+
+```xml
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Wenn Sie die JAR‑Verwaltung manuell bevorzugen, laden Sie das neueste Release von der offiziellen Seite herunter: [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/).
+
+## Wie man Diagrammbilder in Java Schritt für Schritt ersetzt
+
+### Wie initialisiert man den Watermarker für eine Diagrammdatei?
+Watermarker ist die Hauptklasse, die ein Dokument repräsentiert und Methoden zur Inhaltsmanipulation bereitstellt. Erstellen Sie zunächst ein `Watermarker`‑Objekt, das die Diagrammdatei in den Speicher lädt. Die Klasse `Watermarker` ist der zentrale Einstiegspunkt von GroupDocs.Watermark und ermöglicht das Lesen, Ändern und Speichern von Dokumenten. Verwenden Sie `DiagramLoadOptions`, um format‑spezifische Einstellungen wie DPI oder Seitenbereich festzulegen. `DiagramLoadOptions` konfiguriert, wie ein Diagramm geladen wird, z. B. DPI‑Einstellung oder Lademodus.
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### Wie greift man auf den Diagramminhalt zu, um Formen zu finden?
+Nach dem Laden der Datei rufen Sie ein `DiagramContent`‑Objekt vom `Watermarker` ab. `DiagramContent` stellt die interne Hierarchie von Seiten und Formen des Diagramms dar. Dieses Modell bietet Sammlungen von Seiten und Formen, über die Sie iterieren können, sodass das Auffinden bestimmter Elemente wie Bilder oder Text einfach ist.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### Wie ersetzt man Formbilder in einem Diagramm?
+Durchlaufen Sie jede `DiagramShape` auf der gewünschten Seite, prüfen Sie, ob die Form ein Bild enthält, und ersetzen Sie die Bildbytes durch die eines neuen Bildes. `DiagramShape` ist das Modell für eine einzelne Form im Diagramm, während `DiagramWatermarkableImage` Bilddaten speichert, die auf eine Form angewendet werden können.
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### Wie speichert man die Änderungen und schließt den Watermarker?
+Wenn alle Änderungen abgeschlossen sind, rufen Sie `save` auf dem `Watermarker` auf, um das aktualisierte Diagramm in eine Datei zu schreiben, und anschließend `close`, um native Ressourcen freizugeben. Dadurch werden Dateihandles geschlossen und Speicherlecks vermieden, insbesondere bei der Stapelverarbeitung vieler Diagramme.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+
+public class FeatureSaveAndCloseWatermarker {
+ public static void run(Watermarker watermarker) throws Exception {
+ String outputPath = "YOUR_OUTPUT_DIRECTORY/output.vsdx";
+ watermarker.save(outputPath);
+ watermarker.close();
+ }
+}
+```
+```
+
+## Hinzufügen eines Wasserzeichens zum selben Diagramm (optional)
+
+Falls Sie das Diagramm zusätzlich branden möchten, können Sie ein Wasserzeichen vor oder nach dem Bildaustausch hinzufügen:
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+
+## Häufige Fallstricke und Fehlersuche
+
+| Symptom | Wahrscheinliche Ursache | Lösung |
+|---------|--------------------------|--------|
+| Keine Bildänderung nach Ausführen des Codes | `DiagramShape.hasImage()` gab false zurück | Überprüfen Sie den Formtyp; einige Vektorformen speichern Bilder anders. |
+| OutOfMemoryError bei großen Dateien | Laden des gesamten Diagramms auf einmal | Verwenden Sie `DiagramLoadOptions.setLoadMode(LoadMode.Stream)`, um Seiten sequenziell zu verarbeiten. |
+| Wasserzeichen nicht sichtbar | Wasserzeichen hinter bestehendem Inhalt platziert | Rufen Sie `watermarker.setWatermarkPosition(Position.Foreground)` vor dem Speichern auf. |
+
+## Häufig gestellte Fragen
+
+**Q: Kann ich Bilder in passwortgeschützten Diagrammen ersetzen?**
+A: Ja. Übergeben Sie das Passwort an `DiagramLoadOptions`, wenn Sie den `Watermarker` erstellen.
+
+**Q: Unterstützt die Bibliothek .drawio (XML)-Dateien?**
+A: Absolut – GroupDocs.Watermark unterstützt das Draw.io‑XML‑Format und behandelt jeden Knoten als Form.
+
+**Q: Wie viele Diagramme kann ich parallel verarbeiten?**
+A: Die Bibliothek ist für Lese‑Only‑Operationen thread‑sicher; bei Schreiboperationen sollten Sie die Parallelität auf die Anzahl der CPU‑Kerne beschränken, um Dateihandle‑Konflikte zu vermeiden.
+
+**Q: Gibt es ein Limit für die Bildgröße?**
+A: Bilder bis zu 100 MB werden unterstützt; größere Dateien sollten vorher verkleinert werden, um den Speicherverbrauch gering zu halten.
+
+**Q: Welche Lizenzierungsoptionen gibt es?**
+A: Sie können mit einer kostenlosen 30‑Tage‑Testversion beginnen; für den Produktionseinsatz ist eine kostenpflichtige Lizenz erforderlich, die Sie im GroupDocs‑Store erhalten können.

+# Schützen Sie Diagramme des geistigen Eigentums mit GroupDocs.Watermark
+
+Das Schützen von Diagrammen des geistigen Eigentums ist ein kritischer Schritt für jede Organisation, die Design‑Assets, Flussdiagramme oder Architekturzeichnungen teilt. Mit GroupDocs.Watermark für Java können Sie programmgesteuert Diagrammdateien (wie `.vsdx`) laden, Bildwasserzeichen‑Instanzen erkennen, nach Textwasserzeichen suchen und sie sicher entfernen, ohne die ursprüngliche Zeichnung zu beschädigen. Dieses Tutorial führt Sie durch den gesamten Prozess – von der Einrichtung der Umgebung bis zur Stapelverarbeitung großer Diagrammbibliotheken – sodass Sie einen robusten IP‑Schutz direkt in Ihre Java‑Anwendungen einbetten können.
+
+## Schnelle Antworten
+- **Welche Bibliothek verarbeitet Diagramm‑Wasserzeichen?** GroupDocs.Watermark for Java.
+- **Kann ich Bildwasserzeichen ebenso wie Text erkennen?** Ja, die API bietet `ImageDctHashSearchCriteria` für die Bilderkennung und `TextSearchCriteria` für Text.
+- **Benötige ich eine kommerzielle Lizenz, um den Code auszuführen?** Eine Testlizenz funktioniert für die Entwicklung; für die Produktion ist eine kostenpflichtige Lizenz erforderlich.
+- **Wird die Stapelverarbeitung unterstützt?** Absolut – iterieren Sie über einen Ordner und wenden Sie die gleiche Wasserzeichen‑Logik auf jede Datei an.
+- **Bleibt das ursprüngliche Diagrammlayout nach dem Entfernen erhalten?** Die Bibliothek entfernt nur Wasserzeichen‑Objekte und bewahrt alle Formen, Verbindungen und Formatierungen.
+
+## Was sind Diagramme des geistigen Eigentums?
+Diagramme des geistigen Eigentums sind visuelle Darstellungen – wie Flussdiagramme, UML‑Modelle, Netzwerkschemata oder Architekturzeichnungen – die proprietäre Informationen enthalten, die einer Person oder Organisation gehören. Diese Diagramme vermitteln häufig vertrauliche Prozesse, Designs oder Strategien und stellen wertvolle Assets dar, die vor unbefugtem Kopieren, Verteilen oder Ändern geschützt werden müssen. Indem man sie als geistiges Eigentum behandelt, kann man rechtliche und technische Schutzmaßnahmen, einschließlich Wasserzeichen, anwenden, um die Kontrolle über ihre Nutzung und Verbreitung zu behalten.
+
+## Warum GroupDocs.Watermark für Java verwenden?
+GroupDocs.Watermark unterstützt **mehr als 50 Eingabe‑ und Ausgabeformate** (einschließlich `.vsdx`, `.vdx`, `.vsx`) und kann Diagramme mit mehreren hundert Seiten verarbeiten, ohne die gesamte Datei in den Speicher zu laden, wodurch der RAM‑Verbrauch im Vergleich zu naiven Datei‑Stream‑Ansätzen um bis zu **70 %** reduziert wird. Die API bietet zudem einen integrierten, OCR‑freien Bild‑Hash‑Vergleich, der zuverlässige `detect image watermark`‑Operationen in weniger als **200 ms** pro Diagramm auf einem typischen 2,5 GHz‑Server ermöglicht.
+
+## Voraussetzungen
+1. **Java Development Kit (JDK) 8+** – Der Code verwendet die Standard‑Java 8‑APIs.
+2. **IDE** – IntelliJ IDEA, Eclipse oder ein beliebiger Editor Ihrer Wahl.
+3. **GroupDocs.Watermark für Java** – entweder über Maven oder einen manuellen JAR‑Download.
+
+### Erforderliche Bibliotheken und Abhängigkeiten
+Sie können die Bibliothek über Maven hinzufügen oder die JARs direkt herunterladen.
+
+#### Maven‑Einrichtung
+Fügen Sie die Repository‑ und Abhängigkeits‑Einträge zu Ihrer `pom.xml`‑Datei hinzu:
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+
+#### Direkter Download
+Wenn Sie eine manuelle Installation bevorzugen, laden Sie das neueste Release von [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/) herunter.
+
+### Lizenzbeschaffung

+
+## Wie initialisiert man den Watermarker?
+Das Erstellen einer `Watermarker`‑Instanz ist der erste Schritt in jedem Wasserzeichen‑Workflow. Die Klasse `Watermarker` lädt eine Diagrammdatei in den Speicher und stellt Methoden zum Suchen, Hinzufügen und Entfernen von Wasserzeichen bereit. Durch Übergabe des Diagrammpfads und optionaler `DiagramLoadOptions` erhalten Sie ein Objekt, das als zentrale Anlaufstelle für alle nachfolgenden Vorgänge dient und eine konsistente Handhabung des Dokuments während des gesamten Prozesses gewährleistet.
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## Wie lädt man ein Diagrammdokument?
+Das Laden eines Diagramms mit `DiagramLoadOptions` bietet Ihnen eine feinkörnige Kontrolle darüber, wie die Datei geparst wird. `DiagramLoadOptions` ermöglicht es, festzulegen, ob nur sichtbare Seiten geladen werden sollen, ob versteckte Ebenen erhalten bleiben und wie eingebettete Schriftarten behandelt werden. Die Anpassung dieser Optionen kann die Leistung bei großen Diagrammen erheblich verbessern und stellt sicher, dass nur die notwendigen Teile der Datei verarbeitet werden, wodurch der Speicherverbrauch reduziert und die Wasserzeichen‑Erkennung beschleunigt wird.
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## Wie erkennt man Bildwasserzeichen in einem Diagramm?
+Die Erkennung von Bildwasserzeichen basiert auf der Klasse `ImageDctHashSearchCriteria`, die einen perceptual‑Hash eines Referenzbildes berechnet und diesen mit jedem eingebetteten Bild im Diagramm vergleicht. Diese Methode ist schnell und tolerant gegenüber kleinen visuellen Abweichungen, sodass Sie Logos oder andere grafische Wasserzeichen selbst dann finden können, wenn sie skaliert oder leicht verändert wurden. Durch Konfiguration des Ähnlichkeitsschwellenwerts können Sie die Empfindlichkeit der Erkennung gegen Fehl‑Positiv‑Treffer abwägen.
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## Wie sucht man nach Textwasserzeichen?
+Die Suche nach Textwasserzeichen verwendet die Klasse `TextSearchCriteria`. Diese Klasse durchsucht alle Textebenen im Diagramm, einschließlich derjenigen in Formen, Verbindungen und Gruppierungen, und gibt alle Treffer zurück, die die angegebene Zeichenkette oder das Muster enthalten. Die Suche ist standardmäßig case‑insensitive und kann mit regulären Ausdrücken verfeinert werden, sodass Sie Wasserzeichen finden können, die gedreht, teilweise verborgen oder in komplexen Diagrammstrukturen eingebettet sind.
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## Wie entfernt man Wasserzeichen aus einem Diagramm?
+Das Entfernen von Wasserzeichen erfolgt durch Aufruf der `clear()`‑Methode auf jedem `Watermark`‑Objekt, das von einer Suchoperation zurückgegeben wird. Die `clear()`‑Methode löscht nur die visuellen Wasserzeichen‑Elemente, während die zugrunde liegenden Diagrammobjekte – wie Formen, Verbindungen und Formatierungen – unverändert bleiben. Nach dem Löschen speichern Sie das Dokument mit der `save`‑Methode, wodurch eine bereinigte Version des Diagramms entsteht, die das ursprüngliche Layout und die Funktionalität beibehält.
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## Praktische Anwendungen
+- **Integration in Unternehmenssoftware:** Wasserzeichen‑Validierung in Dokumenten‑Management‑Systeme einbetten, um IP‑Richtlinien automatisch durchzusetzen.
+- **Content‑Management‑Systeme (CMS):** Benutzer‑hochgeladene Diagramme auf unautorisierte Logos prüfen, bevor sie veröffentlicht werden.
+- **Umgang mit juristischen Dokumenten:** Vertrauliche Wasserzeichen erkennen und entfernen, wenn Beweismaterialien zusammengestellt werden.
+
+## Häufige Fallstricke und Fehlersuche
+- **Fehlende Lizenz‑Ausnahme:** Stellen Sie sicher, dass die Test‑ oder kostenpflichtige Lizenzdatei korrekt über `License.setLicense("license_path")` referenziert wird.
+- **Verlangsamung bei großen Diagrammen:** Aktivieren Sie `loadOptions.setLoadHiddenLayers(false)` und erwägen Sie die Verarbeitung von Diagrammen in parallelen Streams.
+- **Falsch‑positive Bild‑Übereinstimmungen:** Passen Sie die DCT‑Hash‑Toleranz mit `criteria.setSimilarityThreshold(0.85)` an, um versehentliche Treffer zu reduzieren.
+
+## Häufig gestellte Fragen
+
+**F: Kann ich sowohl Text‑ als auch Bildwasserzeichen in einem einzigen Aufruf suchen?**
+A: Ja, kombinieren Sie Kriterien mit `OrSearchCriteria` (z. B. `new OrSearchCriteria(textCriteria, imageCriteria)`), um beide Typen gleichzeitig abzurufen.
+
+**F: Wird das Entfernen von Wasserzeichen das Diagrammlayout beschädigen?**
+A: Nein. Die Bibliothek isoliert Wasserzeichen‑Objekte, sodass Formen, Verbindungen und Formatierungen nach `clear()` unverändert bleiben.
+
+**F: Welche Diagrammformate werden unterstützt?**
+A: GroupDocs.Watermark verarbeitet `.vsdx`, `.vdx`, `.vsx` und mehrere ältere Visio‑Formate und deckt über **30** Diagrammtypen ab.
+
+**F: Wie verarbeite ich Tausende von Diagrammen effizient?**
+A: Nutzen Sie Java’s `ExecutorService`, um die Wasserzeichen‑Erkennung/‑Entfernung in parallelen Stapeln auszuführen, und verwenden Sie ein einzelnes `Watermarker`‑Konfigurationsobjekt wieder, um den Overhead zu reduzieren.
+
+**F: Ist es möglich, dies in eine CI/CD‑Pipeline zu integrieren?**
+A: Absolut. Fügen Sie die Java‑Snippets zu Ihren Build‑Skripten (Maven/Gradle) hinzu und führen Sie sie als Vor‑Deployment‑Verifizierungsschritt aus, um sicherzustellen, dass keine verbotenen Wasserzeichen vorhanden sind.

+# Πώς να προσθέσετε υδατογράφημα σε σελίδες διαγράμματος με κείμενο σε Java
+
+Σε σύγχρονα έργα λογισμικού, η προστασία των οπτικών περιουσιακών στοιχείων που μοιράζεστε—ιδιαίτερα των διαγραμμάτων—έχει γίνει κορυφαία προτεραιότητα. **How to watermark diagram** pages with text in Java είναι μια κοινή απαίτηση για εταιρείες που χρειάζονται να διατηρήσουν την ταυτότητα της μάρκας, να αποτρέψουν την μη εξουσιοδοτημένη επαναχρησιμοποίηση και να παρακολουθούν την προέλευση των εγγράφων. Αυτό το σεμινάριο σας καθοδηγεί μέσω όλης της διαδικασίας χρησιμοποιώντας το **GroupDocs.Watermark for Java**, από την προετοιμασία του περιβάλλοντος μέχρι την τελική επαλήθευση, ώστε να μπορείτε με σιγουριά να ασφαλίσετε τα διαγράμματά σας.
+
+## Γρήγορες απαντήσεις
+- **Ποια βιβλιοθήκη προσθέτει υδατογραφήματα;** GroupDocs.Watermark for Java.
+- **Ποια έκδοση Java απαιτείται;** JDK 8 ή νεότερο.
+- **Χρειάζομαι άδεια για δοκιμή;** Μια δωρεάν προσωρινή άδεια λειτουργεί για αξιολόγηση.
+- **Μπορώ να προσθέσω υδατογράφημα σε πολλές σελίδες ταυτόχρονα;** Ναι—εφαρμόστε το υδατογράφημα σε όλες τις σελίδες με μία κλήση.
+- **Είναι η διαδικασία αποδοτική στη μνήμη;** Το API μεταδίδει τις σελίδες, έτσι ακόμη και διαγράμματα 500 σελίδων παραμένουν κάτω από 200 MB RAM.
+
+## Τι είναι η τοποθέτηση υδατογραφήματος σε σελίδες διαγράμματος σε Java;
+Περιλαμβάνει την προγραμματιστική επικάλυψη ημιδιαφανούς κειμένου (ή εικόνων) πάνω σε κάθε σελίδα ενός αρχείου διαγράμματος—όπως Visio, SVG ή άλλες υποστηριζόμενες μορφές—χρησιμοποιώντας μια βιβλιοθήκη Java. Το υδατογράφημα γίνεται μέρος του οπτικού περιεχομένου, καθιστώντας το ορατό σε οποιονδήποτε προβολέα ενώ διατηρεί τα αρχικά δεδομένα του διαγράμματος.
+
+## Γιατί να χρησιμοποιήσετε το GroupDocs.Watermark for Java;
+Το GroupDocs.Watermark υποστηρίζει **50+ μορφές εισόδου και εξόδου**, επεξεργάζεται αρχεία έως **1 GB** χωρίς να φορτώνει ολόκληρο το έγγραφο στη μνήμη, και προσφέρει **ενσωματωμένο OCR** για την ανίχνευση υπαρχόντων υδατογραφημάτων. Αυτές οι μετρήσιμες δυνατότητες εξασφαλίζουν γρήγορη, αξιόπιστη προστασία για μεγάλης κλίμακας αποθετήρια διαγραμμάτων, ενώ το API του απλοποιεί την ενσωμάτωση σε εφαρμογές Java.
+
+## Προαπαιτούμενα
+- **Java Development Kit (JDK)** 8 ή νεότερο εγκατεστημένο στον υπολογιστή σας.
+- Ένα IDE όπως **IntelliJ IDEA** ή **Eclipse** για επεξεργασία και εκτέλεση κώδικα Java.
+- Βασική εξοικείωση με το Maven για διαχείριση εξαρτήσεων.
+
+### Απαιτούμενες βιβλιοθήκες και εξαρτήσεις
+Θα χρησιμοποιήσουμε το GroupDocs.Watermark for Java, το οποίο μπορείτε να προσθέσετε στο Maven project σας:
+
+```xml
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Αν προτιμάτε χειροκίνητη εγκατάσταση, κατεβάστε τα binaries από τη σελίδα επίσημης έκδοσης [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/) και προσθέστε τα στο classpath του project σας.
+
+### Απόκτηση άδειας
+Ξεκινήστε με δωρεάν δοκιμή αποκτώντας προσωρινή άδεια από [GroupDocs.Trial Licensing](https://purchase.groupdocs.com/temporary-license/). Για παραγωγική χρήση, αγοράστε πλήρη άδεια και τοποθετήστε το αρχείο `license.json` σε θέση όπου η εφαρμογή σας μπορεί να το διαβάσει:
+
+```java
+// Load the temporary or purchased license – keep unchanged
+```java
+License license = new License();
+license.setLicense("path/to/license/file");
+```
+```
+
+## Οδηγός υλοποίησης
+Παρακάτω υπάρχει ένας βήμα‑βήμα οδηγός που δείχνει ακριβώς πώς να ενσωματώσετε ένα κειμενικό υδατογράφημα σε κάθε σελίδα ενός διαγράμματος.
+
+### Πώς να προσθέσω κειμενικό υδατογράφημα σε σελίδα διαγράμματος;
+Φορτώστε το διάγραμμα, δημιουργήστε ένα αντικείμενο `TextWatermark`, εφαρμόστε το στις επιθυμητές σελίδες και τέλος αποθηκεύστε το αποτέλεσμα. Αυτή η ολοκληρωμένη ροή απαιτεί μόνο τέσσερις σύντομες κλήσεις API και εκτελείται σε λιγότερο από ένα δευτερόλεπτο για τυπικά αρχεία 10 σελίδων, ενώ επιτρέπει προσαρμογή γραμματοσειράς, χρώματος, διαφάνειας και περιστροφής.
+
+#### Βήμα 1: φορτώστε το διάγραμμά σας
+Το DiagramLoadOptions καθορίζει στη βιβλιοθήκη πώς να διαβάσει αρχεία διαγράμματος, όπως η διαχείριση κωδικών πρόσβασης ή συγκεκριμένων επιλογών μορφής. Πρώτα, δημιουργήστε ένα `Watermarker` με `DiagramLoadOptions`. Αυτό το αντικείμενο αντιπροσωπεύει το πηγαίο διάγραμμα στη μνήμη.
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### Βήμα 2: αρχικοποιήστε το κειμενικό υδατογράφημα
+`TextWatermark` ορίζει το ορατό κείμενο, τη γραμματοσειρά, το χρώμα και την περιστροφή. Μπορείτε επίσης να ορίσετε τη διαφάνεια για να κάνετε το υδατογράφημα διακριτικό.
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### Βήμα 3: προσθέστε υδατογράφημα σε σελίδες διαγράμματος
+Το DiagramShapeWatermarkOptions διαμορφώνει πώς εφαρμόζεται ένα υδατογράφημα σε σχήματα διαγράμματος. Το DiagramWatermarkPlacementType καθορίζει αν το υδατογράφημα εμφανίζεται στο προσκήνιο ή στο παρασκήνιο. Εφαρμόστε το υδατογράφημα σε όλες τις σελίδες παρασκηνίου (ή σε προσαρμοσμένο εύρος σελίδων). Το API μεταδίδει κάθε σελίδα, έτσι η χρήση μνήμης παραμένει χαμηλή ακόμη και για μεγάλα αρχεία.
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### Βήμα 4: αποθήκευση και κλείσιμο
+Αποθηκεύστε το υδατογραφημένο διάγραμμα σε νέο αρχείο και απελευθερώστε τους πόρους.
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### Συχνά προβλήματα και λύσεις
+- **Προβλήματα διαδρομής αρχείου:** Χρησιμοποιήστε απόλυτες διαδρομές ή επαληθεύστε ότι ο τρέχων φάκελος ταιριάζει με τη θέση των αρχείων διαγράμματος.
+- **Ασυμφωνίες εκδόσεων:** Οι εκδόσεις του GroupDocs.Watermark συνδέονται με συγκεκριμένες εκδόσεις JDK· βεβαιωθείτε ότι χρησιμοποιείτε συμβατή έκδοση JDK 8‑17.
+- **Σημεία συμφόρησης απόδοσης:** Για επεξεργασία σε παρτίδες, επαναχρησιμοποιήστε ένα μόνο αντικείμενο `Watermarker` και καλέστε `close()` μόνο μετά την ολοκλήρωση της παρτίδας.
+
+## Πρακτικές εφαρμογές
+Τα κειμενικά υδατογραφήματα είναι χρήσιμα σε πολλές πραγματικές περιπτώσεις:
+
+1. **Ασφάλεια εγγράφων** – Αποτρέπει τους ανταγωνιστές από την επαναχρησιμοποίηση ιδιόκτητων διαγραμμάτων.
+2. **Ενίσχυση μάρκας** – Ενσωματώνει το όνομα ή το σλόγκαν της εταιρείας απευθείας σε κάθε σελίδα.
+3. **Παρακολούθηση συνεργασίας** – Προσθέτει αρχικά χρήστη ή χρονικές σημάνσεις για να υποδείξει ποιος επεξεργάστηκε το διάγραμμα.
+
+## Σκέψεις για την απόδοση
+- **Διαχείριση μνήμης:** Η βιβλιοθήκη επεξεργάζεται τις σελίδες αργά· πάντα καλέστε `watermarker.close()` για να ελευθερώσετε τους εγγενείς πόρους.
+- **Μέγεθος υδατογραφήματος:** Μεγαλύτερες γραμματοσειρές αυξάνουν τον χρόνο επεξεργασίας γραμμικά· μια γραμματοσειρά 12 pt είναι καλή ισορροπία για αναγνωσιμότητα και ταχύτητα.
+- **Δοκιμή παρτίδας:** Εκτελέστε τη ρουτίνα υδατογράφησης σε αντιπροσωπευτικό δείγμα πριν την κλιμάκωση σε χιλιάδες αρχεία.
+
+## Συμπέρασμα
+Τώρα έχετε μια πλήρη, έτοιμη για παραγωγή μέθοδο για **how to watermark diagram** σελίδες με κείμενο σε Java χρησιμοποιώντας το GroupDocs.Watermark. Αυτή η δυνατότητα όχι μόνο ασφαλίζει τα οπτικά σας περιουσιακά στοιχεία αλλά και ενισχύει τη συνέπεια της μάρκας σε όλα τα κοινόχρηστα διαγράμματα.
+
+### Επόμενα βήματα
+- Εξερευνήστε υδατογραφήματα εικόνας για πρόσθετη οπτική επωνυμία.
+- Συνδυάστε κειμενικά και εικόνα υδατογραφήματα για πολυεπίπεδη προστασία.
+- Ενσωματώστε τη ροή υδατογράφησης στο CI/CD pipeline σας για αυτοματοποίηση της ασφάλειας διαγραμμάτων.
+
+## Συχνές ερωτήσεις
+1. **Μπορώ να χρησιμοποιήσω το GroupDocs.Watermark για άλλες μορφές αρχείων;**
+ Ναι—υποστηρίζονται πάνω από 50 μορφές, συμπεριλαμβανομένων PDF, DOCX, PPTX και SVG.
+
+2. **Υπάρχει όριο στον αριθμό των υδατογραφημάτων που μπορώ να προσθέσω;**
+ Δεν υπάρχει σκληρό όριο, αλλά η προσθήκη περισσότερων από 10 ανά σελίδα μπορεί να επηρεάσει την ταχύτητα απόδοσης.
+
+3. **Πώς αφαιρώ ένα υδατογράφημα από ένα διάγραμμα;**
+ Χρησιμοποιήστε το API `Watermarker.removeWatermarks()` για να εντοπίσετε και να διαγράψετε υπάρχοντα υδατογραφήματα.
+
+4. **Μπορώ να στοχεύσω μόνο συγκεκριμένες σελίδες;**
+ Απόλυτα—ρυθμίστε το `WatermarkOptions` με εύρος σελίδων ή προσαρμοσμένο πρότυπο.
+
+5. **Τι πρέπει να κάνω αν το υδατογράφημα δεν είναι ορατό;**
+ Επαληθεύστε τις ρυθμίσεις διαφάνειας, αντίθεσης χρώματος και περιστροφής· συμβουλευτείτε την τεκμηρίωση του API για αντιμετώπιση προβλημάτων.
+
+### Πρόσθετες ερωτήσεις & απαντήσεις
+**Q: Υποστηρίζει η βιβλιοθήκη διαγράμματα με κωδικό πρόσβασης;**
+A: Ναι—περάστε τον κωδικό στο `DiagramLoadOptions` κατά τη φόρτωση του αρχείου.
+
+**Q: Μπορώ να το τρέξω σε headless server;**
+A: Το API είναι πλήρως server‑side και δεν απαιτεί στοιχεία GUI.

+# Αντικατάσταση εικόνων διαγράμματος σε Java χρησιμοποιώντας το GroupDocs.Watermark
+
+Η ενημέρωση εικόνων μέσα σε αρχεία διαγράμματος με το χέρι είναι χρονοβόρα και επιρρεπής σε σφάλματα. Σε αυτό το σεμινάριο θα μάθετε πώς να **αντικαταστήσετε εικόνες διαγράμματος σε Java** με λίγες μόνο γραμμές κώδικα, και επίσης θα δείτε πώς να **προσθέσετε υδατογράφημα σε διάγραμμα** όταν χρειάζεται. Στο τέλος θα έχετε ένα επαναχρησιμοποιήσιμο απόσπασμα κώδικα που μπορείτε να ενσωματώσετε σε οποιοδήποτε έργο Java που λειτουργεί με Visio, Draw.io ή άλλες υποστηριζόμενες μορφές διαγράμματος.
+
+## Γρήγορες απαντήσεις
+- **Ποια βιβλιοθήκη διαχειρίζεται την αντικατάσταση εικόνων διαγράμματος;** GroupDocs.Watermark for Java.
+- **Πόσες γραμμές κώδικα απαιτούνται για μια βασική αντικατάσταση;** Only three lines after the Watermarker is created.
+- **Μπορώ να προσθέσω υδατογράφημα ταυτόχρονα;** Yes – use the same Watermarker instance with a watermark object.
+- **Ποια έκδοση της Java απαιτείται;** JDK 8 or higher.
+- **Χρειάζομαι άδεια για χρήση σε παραγωγή;** A valid GroupDocs.Watermark license is required; a free trial is available.
+
+## Τι είναι η αντικατάσταση εικόνων διαγράμματος σε Java;
+Η αντικατάσταση εικόνων διαγράμματος σε Java σημαίνει τον προγραμματιστικό εντοπισμό σχημάτων που περιέχουν bitmap γραφικά μέσα σε ένα αρχείο διαγράμματος (όπως .vsdx, .drawio ή .svg) και την ανταλλαγή αυτών των ενσωματωμένων εικόνων με νέες χρησιμοποιώντας το GroupDocs.Watermark API. Αυτό αυτοματοποιεί τις ενημερώσεις που διαφορετικά θα απαιτούσαν χειροκίνητη επεξεργασία σε έναν επεξεργαστή διαγράμματος.
+
+## Γιατί να χρησιμοποιήσετε το GroupDocs.Watermark για την αντικατάσταση εικόνων διαγράμματος;
+Το GroupDocs.Watermark υποστηρίζει **50+ μορφές εισόδου και εξόδου** – συμπεριλαμβανομένων των Visio, Draw.io και SVG – και μπορεί να επεξεργαστεί **αρχεία έως 500 MB** χωρίς να φορτώνει ολόκληρο το έγγραφο στη μνήμη, παρέχοντάς σας **μείωση 30 % στη χρήση CPU** σε σύγκριση με τις απλές προσεγγίσεις ροής αρχείων.
+
+## Προαπαιτούμενα
+- JDK 8 ή νεότερο εγκατεστημένο.
+- Ένα IDE (IntelliJ IDEA, Eclipse ή VS Code) για ανάπτυξη Java.
+- Maven (ή η δυνατότητα προσθήκης JAR χειροκίνητα).
+- Ένα έγκυρο άδεια GroupDocs.Watermark (δοκιμαστική ή μόνιμη). Μπορείτε να αποκτήσετε άδεια από [GroupDocs](https://purchase.groupdocs.com/temporary-license/).
+
+### Απαιτούμενες βιβλιοθήκες, εκδόσεις και εξαρτήσεις
+Προσθέστε το αποθετήριο και την εξάρτηση GroupDocs.Watermark στο `pom.xml` σας:
+
+```xml
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Αν προτιμάτε τη χειροκίνητη διαχείριση JAR, κατεβάστε την πιο πρόσφατη έκδοση από την επίσημη ιστοσελίδα: [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/).
+
+## Πώς να αντικαταστήσετε εικόνες διαγράμματος σε Java βήμα προς βήμα
+
+### Πώς να αρχικοποιήσετε το Watermarker για ένα αρχείο διαγράμματος;
+Το Watermarker είναι η κύρια κλάση που αντιπροσωπεύει ένα έγγραφο και παρέχει μεθόδους για την επεξεργασία περιεχομένου. Για να ξεκινήσετε, δημιουργήστε ένα αντικείμενο `Watermarker` που φορτώνει το αρχείο διαγράμματος στη μνήμη. Η κλάση `Watermarker` είναι το κεντρικό σημείο εισόδου του GroupDocs.Watermark, επιτρέποντάς σας να διαβάζετε, να τροποποιείτε και να αποθηκεύετε έγγραφα. Χρησιμοποιήστε το `DiagramLoadOptions` για να καθορίσετε ρυθμίσεις ειδικές για τη μορφή, όπως DPI ή εύρος σελίδων. Το `DiagramLoadOptions` διαμορφώνει πώς φορτώνεται ένα διάγραμμα, π.χ., ορίζοντας DPI ή τρόπο φόρτωσης.
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### Πώς μπορείτε να αποκτήσετε πρόσβαση στο περιεχόμενο του διαγράμματος για να εντοπίσετε σχήματα;
+Μετά τη φόρτωση του αρχείου, ανακτήστε ένα αντικείμενο `DiagramContent` από το `Watermarker`. Το `DiagramContent` αντιπροσωπεύει την εσωτερική ιεραρχία του διαγράμματος με σελίδες και σχήματα. Αυτό το μοντέλο εκθέτει συλλογές σελίδων και σχημάτων που μπορείτε να διασχίσετε, διευκολύνοντας τον εντοπισμό συγκεκριμένων στοιχείων όπως εικόνες ή κείμενο.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### Πώς να αντικαταστήσετε τις εικόνες σχήματος σε ένα διάγραμμα;
+Επανάληψη σε κάθε `DiagramShape` στην επιθυμητή σελίδα, έλεγχος εάν το σχήμα περιέχει εικόνα, και αντικατάσταση των bytes της εικόνας με αυτά ενός νέου αρχείου. Το `DiagramShape` είναι το μοντέλο για ένα μεμονωμένο σχήμα σε ένα διάγραμμα, ενώ το `DiagramWatermarkableImage` αποθηκεύει τα δεδομένα εικόνας που μπορούν να εφαρμοστούν σε ένα σχήμα.
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### Πώς να αποθηκεύσετε τις αλλαγές και να κλείσετε το Watermarker;
+Όταν ολοκληρωθούν όλες οι τροποποιήσεις, καλέστε `save` στο `Watermarker` για να γράψετε το ενημερωμένο διάγραμμα σε αρχείο, στη συνέχεια καλέστε `close` για να απελευθερώσετε τους εγγενείς πόρους. Αυτό εξασφαλίζει ότι τα handles των αρχείων ελευθερώνονται και αποτρέπει διαρροές μνήμης, ειδικά όταν επεξεργάζεστε πολλά διαγράμματα σε μια παρτίδα εργασίας.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+
+public class FeatureSaveAndCloseWatermarker {
+ public static void run(Watermarker watermarker) throws Exception {
+ String outputPath = "YOUR_OUTPUT_DIRECTORY/output.vsdx";
+ watermarker.save(outputPath);
+ watermarker.close();
+ }
+}
+```
+```
+
+## Προσθήκη υδατογραφήματος στο ίδιο διάγραμμα (προαιρετικό)
+
+Αν χρειάζεστε επίσης να επισημάνετε το διάγραμμα, μπορείτε να προσθέσετε υδατογράφημα πριν ή μετά την αντικατάσταση της εικόνας:
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+
+## Συνηθισμένα προβλήματα και αντιμετώπιση
+
+| Σύμπτωμα | Πιθανή αιτία | Διόρθωση |
+|----------|--------------|----------|
+| Καμία αλλαγή εικόνας μετά την εκτέλεση του κώδικα | `DiagramShape.hasImage()` επέστρεψε false | Επαληθεύστε τον τύπο του σχήματος· ορισμένα διανυσματικά σχήματα αποθηκεύουν εικόνες διαφορετικά. |
+| OutOfMemoryError σε μεγάλα αρχεία | Φόρτωση ολόκληρου του διαγράμματος ταυτόχρονα | Χρησιμοποιήστε `DiagramLoadOptions.setLoadMode(LoadMode.Stream)` για επεξεργασία σελίδων διαδοχικά. |
+| Το υδατογράφημα δεν είναι ορατό | Το υδατογράφημα τοποθετήθηκε πίσω από το υπάρχον περιεχόμενο | Καλέστε `watermarker.setWatermarkPosition(Position.Foreground)` πριν την αποθήκευση. |
+
+## Συχνές ερωτήσεις
+
+**Q: Μπορώ να αντικαταστήσω εικόνες σε διαγράμματα με προστασία κωδικού;**
+A: Yes. Pass the password to `DiagramLoadOptions` when creating the `Watermarker`.
+
+**Q: Η βιβλιοθήκη λειτουργεί με αρχεία .drawio (XML);**
+A: Absolutely – GroupDocs.Watermark supports the Draw.io XML format and treats each node as a shape.
+
+**Q: Πόσα διαγράμματα μπορώ να επεξεργαστώ παράλληλα;**
+A: The library is thread‑safe for read‑only operations; for write operations, limit concurrency to the number of CPU cores to avoid file‑handle contention.
+
+**Q: Υπάρχει όριο στο μέγεθος της εικόνας;**
+A: Images up to 100 MB are supported; larger files should be resized beforehand to keep memory usage low.
+
+**Q: Ποιες επιλογές αδειοδότησης είναι διαθέσιμες;**
+A: You can start with a free 30‑day trial; production use requires a paid license, which can be obtained from the GroupDocs store.

+
+# Προστασία διαγραμμάτων πνευματικής ιδιοκτησίας με το GroupDocs.Watermark
+
+Η προστασία διαγραμμάτων πνευματικής ιδιοκτησίας είναι ένα κρίσιμο βήμα για κάθε οργανισμό που μοιράζεται περιουσιακά στοιχεία σχεδίασης, διαγράμματα ροής ή αρχιτεκτονικά σχέδια. Με το GroupDocs.Watermark για Java μπορείτε προγραμματιστικά να φορτώσετε αρχεία διαγράμματος (όπως `.vsdx`), να εντοπίσετε περιπτώσεις υδατογραφημάτων εικόνας, να αναζητήσετε υδατογραφήματα κειμένου και να τα αφαιρέσετε με ασφάλεια χωρίς να καταστρέψετε το αρχικό σχέδιο. Αυτό το σεμινάριο σας καθοδηγεί σε όλη τη διαδικασία—από τη ρύθμιση του περιβάλλοντος μέχρι την επεξεργασία μεγάλων βιβλιοθηκών διαγραμμάτων σε παρτίδες—ώστε να ενσωματώσετε αξιόπιστη προστασία IP απευθείας στις εφαρμογές Java.
+
+## Γρήγορες απαντήσεις
+- **Ποια βιβλιοθήκη διαχειρίζεται τα υδατογραφήματα διαγραμμάτων;** GroupDocs.Watermark για Java.
+- **Μπορώ να εντοπίσω υδατογράφημα εικόνας καθώς και κειμένου;** Ναι, το API παρέχει `ImageDctHashSearchCriteria` για εντοπισμό εικόνας και `TextSearchCriteria` για κείμενο.
+- **Χρειάζομαι εμπορική άδεια για την εκτέλεση του κώδικα;** Μια δοκιμαστική άδεια λειτουργεί για ανάπτυξη· απαιτείται πληρωμένη άδεια για παραγωγή.
+- **Υποστηρίζεται η επεξεργασία σε παρτίδες;** Απόλυτα—επαναλάβετε τη διαδικασία σε έναν φάκελο και εφαρμόστε την ίδια λογική υδατογραφημάτων σε κάθε αρχείο.
+- **Θα παραμείνει αμετάβλητη η αρχική διάταξη του διαγράμματος μετά την αφαίρεση;** Η βιβλιοθήκη διαγράφει μόνο τα αντικείμενα υδατογραφημάτων, διατηρώντας όλα τα σχήματα, συνδέσμους και μορφοποίηση.
+
+## Τι είναι τα διαγράμματα πνευματικής ιδιοκτησίας;
+Τα διαγράμματα πνευματικής ιδιοκτησίας είναι οπτικές αναπαραστάσεις—όπως διαγράμματα ροής, μοντέλα UML, σχήματα δικτύων ή αρχιτεκτονικά σχέδια—που περιέχουν ιδιόκτητες πληροφορίες που ανήκουν σε άτομο ή οργανισμό. Αυτά τα διαγράμματα συχνά μεταφέρουν εμπιστευτικές διαδικασίες, σχέδια ή στρατηγικές, καθιστώντας τα πολύτιμα περιουσιακά στοιχεία που απαιτούν προστασία έναντι μη εξουσιοδοτημένων αντιγραφών, διανομής ή τροποποίησης. Θεωρώντας τα ως πνευματική ιδιοκτησία, μπορείτε να εφαρμόσετε νομικές και τεχνικές προστασίες, συμπεριλαμβανομένου του υδατογραφημένου, για να διατηρήσετε τον έλεγχο της χρήσης και διάδοσής τους.
+
+## Γιατί να χρησιμοποιήσετε το GroupDocs.Watermark για Java;
+Το GroupDocs.Watermark υποστηρίζει **50+ μορφές εισόδου και εξόδου** (συμπεριλαμβανομένων `.vsdx`, `.vdx`, `.vsx`) και μπορεί να επεξεργαστεί διαγράμματα εκατοντάδων σελίδων χωρίς να φορτώνει ολόκληρο το αρχείο στη μνήμη, μειώνοντας την κατανάλωση RAM έως **70 %** σε σύγκριση με απλές προσεγγίσεις ροής αρχείου. Το API προσφέρει επίσης ενσωματωμένη σύγκριση εικόνας‑hash χωρίς OCR, επιτρέποντας αξιόπιστες λειτουργίες `detect image watermark` σε λιγότερο από **200 ms** ανά διάγραμμα σε έναν τυπικό διακομιστή 2.5 GHz.

+
+## Πώς να αρχικοποιήσετε το Watermarker;
+Η δημιουργία ενός αντικειμένου `Watermarker` είναι το πρώτο βήμα σε οποιαδήποτε ροή εργασίας υδατογραφημάτων. Η κλάση `Watermarker` φορτώνει ένα αρχείο διαγράμματος στη μνήμη και παρέχει μεθόδους για αναζήτηση, προσθήκη και αφαίρεση υδατογραφημάτων. Με τη διόρθωση της διαδρομής του διαγράμματος και προαιρετικά `DiagramLoadOptions`, λαμβάνετε ένα αντικείμενο που λειτουργεί ως κεντρικό σημείο για όλες τις επόμενες λειτουργίες, εξασφαλίζοντας συνεπή διαχείριση του εγγράφου καθ' όλη τη διαδικασία.
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## Πώς να φορτώσετε ένα έγγραφο διαγράμματος;
+Η φόρτωση ενός διαγράμματος με `DiagramLoadOptions` σας δίνει λεπτομερή έλεγχο του τρόπου ανάλυσης του αρχείου. Το `DiagramLoadOptions` επιτρέπει να καθορίσετε αν θα φορτωθούν μόνο οι ορατές σελίδες, αν θα διατηρηθούν κρυφά στρώματα και πώς θα διαχειριστούν οι ενσωματωμένες γραμματοσειρές. Η ρύθμιση αυτών των επιλογών μπορεί να βελτιώσει δραστικά την απόδοση για μεγάλα διαγράμματα και εξασφαλίζει ότι μόνο τα απαραίτητα τμήματα του αρχείου θα υποβληθούν σε επεξεργασία, μειώνοντας τη χρήση μνήμης και επιταχύνοντας τον εντοπισμό υδατογραφημάτων.
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## Πώς να εντοπίσετε υδατογράφημα εικόνας σε ένα διάγραμμα;
+Η ανίχνευση υδατογραφημάτων εικόνας βασίζεται στην κλάση `ImageDctHashSearchCriteria`, η οποία υπολογίζει ένα αντιληπτικό hash μιας εικόνας αναφοράς και το συγκρίνει με κάθε ενσωματωμένη εικόνα στο διάγραμμα. Αυτή η μέθοδος είναι γρήγορη και ανεκτική σε μικρές οπτικές διαφορές, επιτρέποντας τον εντοπισμό λογοτύπων ή άλλων γραφικών υδατογραφημάτων ακόμη και αν έχουν αλλάξει το μέγεθος ή τροποποιηθεί ελαφρώς. Ρυθμίζοντας το όριο ομοιότητας, μπορείτε να ισορροπήσετε την ευαισθησία εντοπισμού με τα ψευδώς θετικά αποτελέσματα.
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## Πώς να αναζητήσετε υδατογραφήματα κειμένου;
+Η αναζήτηση υδατογραφημάτων κειμένου χρησιμοποιεί την κλάση `TextSearchCriteria`. Αυτή η κλάση σαρώει όλα τα κειμενικά στρώματα του διαγράμματος, συμπεριλαμβανομένων εκείνων μέσα σε σχήματα, συνδέσμους και ομάδες, και επιστρέφει τυχόν αντιστοιχίες που περιέχουν τη συγκεκριμένη συμβολοσειρά ή το μοτίβο. Η αναζήτηση είναι εξ ορισμού μη ευαίσθητη σε πεζά/κεφαλαία και μπορεί να βελτιωθεί με κανονικές εκφράσεις, επιτρέποντάς σας να εντοπίσετε υδατογραφήματα που μπορεί να είναι περιστρεφόμενα, μερικώς κρυμμένα ή ενσωματωμένα σε σύνθετες δομές διαγράμματος.
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## Πώς να αφαιρέσετε υδατογραφήματα από ένα διάγραμμα;
+Η αφαίρεση υδατογραφημάτων πραγματοποιείται καλώντας τη μέθοδο `clear()` σε κάθε αντικείμενο `Watermark` που επιστρέφεται από μια λειτουργία αναζήτησης. Η μέθοδος `clear()` διαγράφει μόνο τα οπτικά στοιχεία του υδατογραφήματος, αφήνοντας ανέπαφα τα υποκείμενα αντικείμενα του διαγράμματος—όπως σχήματα, συνδέσμους και μορφοποίηση. Μετά τον καθαρισμό, αποθηκεύετε το έγγραφο χρησιμοποιώντας τη μέθοδο `save`, παράγοντας μια καθαρή έκδοση του διαγράμματος που διατηρεί την αρχική του διάταξη και λειτουργικότητα.
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## Πρακτικές εφαρμογές
+- **Ενσωμάτωση λογισμικού επιχείρησης:** Ενσωματώστε την επικύρωση υδατογραφημάτων σε συστήματα διαχείρισης εγγράφων για αυτόματη επιβολή πολιτικών IP.
+- **Συστήματα διαχείρισης περιεχομένου (CMS):** Σαρώστε διαγράμματα που ανεβάζουν χρήστες για μη εξουσιοδοτημένα λογότυπα πριν από τη δημοσίευση.
+- **Διαχείριση νομικών εγγράφων:** Εντοπίστε και αφαιρέστε εμπιστευτικά υδατογραφήματα κατά την προετοιμασία πακέτων αποδεικτικών στοιχείων.
+
+## Συχνά προβλήματα και αντιμετώπιση
+- **Εξαίρεση έλλειψης άδειας:** Βεβαιωθείτε ότι το αρχείο δοκιμαστικής ή πληρωμένης άδειας έχει αναφερθεί σωστά μέσω `License.setLicense("license_path")`.
+- **Μείωση ταχύτητας σε μεγάλα διαγράμματα:** Ενεργοποιήστε `loadOptions.setLoadHiddenLayers(false)` και εξετάστε την επεξεργασία διαγραμμάτων σε παράλληλα streams.
+- **Ψευδώς θετικά αποτελέσματα εικόνας:** Ρυθμίστε την ανοχή του DCT hash με `criteria.setSimilarityThreshold(0.85)` για μείωση τυχαίων αντιστοιχίσεων.
+
+## Συχνές ερωτήσεις
+
+**Ε: Μπορώ να αναζητήσω τόσο κείμενο όσο και υδατογράφημα εικόνας με μία κλήση;**
+Α: Ναι, συνδυάστε κριτήρια με `OrSearchCriteria` (π.χ., `new OrSearchCriteria(textCriteria, imageCriteria)`) για να λάβετε και τους δύο τύπους ταυτόχρονα.
+
+**Ε: Θα καταστρέψει η αφαίρεση των υδατογραφημάτων τη διάταξη του διαγράμματος;**
+Α: Όχι. Η βιβλιοθήκη απομονώνει τα αντικείμενα υδατογραφημάτων, έτσι σχήματα, συνδέσμοι και μορφοποίηση παραμένουν αμετάβλητα μετά το `clear()`.
+
+**Ε: Ποιες μορφές διαγραμμάτων υποστηρίζονται;**
+Α: Το GroupDocs.Watermark διαχειρίζεται `.vsdx`, `.vdx`, `.vsx` και αρκετές παλαιότερες μορφές Visio, καλύπτοντας πάνω από **30** τύπους διαγραμμάτων.
+
+**Ε: Πώς μπορώ να επεξεργαστώ χιλιάδες διαγράμματα αποδοτικά;**
+Α: Χρησιμοποιήστε το `ExecutorService` της Java για να εκτελέσετε τον εντοπισμό/αφαίρεση υδατογραφημάτων σε παράλληλες παρτίδες και επαναχρησιμοποιήστε ένα ενιαίο αντικείμενο ρύθμισης `Watermarker` για μείωση του κόστους.
+
+**Ε: Είναι δυνατόν να ενσωματωθεί αυτό σε μια διαδικασία CI/CD;**
+Α: Απόλυτα. Προσθέστε τα αποσπάσματα Java στα σενάρια κατασκευής (Maven/Gradle) και εκτελέστε τα ως βήμα προ-ανάπτυξης για να διασφαλίσετε ότι δεν υπάρχουν απαγορευμένα υδατογραφήματα.

+# डायग्राम पृष्ठों पर टेक्स्ट के साथ वॉटरमार्क कैसे जोड़ें जावा में
+
+आधुनिक सॉफ़्टवेयर प्रोजेक्ट्स में, आप जो दृश्य संपत्तियां साझा करते हैं—विशेषकर डायग्राम—की सुरक्षा अब शीर्ष प्राथमिकता बन गई है। **डायग्राम में वॉटरमार्क कैसे जोड़ें** पृष्ठों पर टेक्स्ट के साथ जावा में एक सामान्य आवश्यकता है उन कंपनियों के लिए जिन्हें ब्रांड पहचान बनाए रखनी है, अनधिकृत पुन: उपयोग को रोकना है, और दस्तावेज़ की उत्पत्ति को ट्रैक करना है। यह ट्यूटोरियल आपको **GroupDocs.Watermark for Java** का उपयोग करके पूरी प्रक्रिया के माध्यम से ले जाता है, पर्यावरण तैयारी से लेकर अंतिम सत्यापन तक, ताकि आप अपने डायग्राम को आत्मविश्वास से सुरक्षित कर सकें।
+
+## त्वरित उत्तर
+- **वॉटरमार्क जोड़ने वाली लाइब्रेरी कौन सी है?** GroupDocs.Watermark for Java.
+- **कौन सा जावा संस्करण आवश्यक है?** JDK 8 या नया.
+- **परीक्षण के लिए लाइसेंस चाहिए?** मूल्यांकन के लिए एक मुफ्त अस्थायी लाइसेंस काम करता है.
+- **क्या मैं एक साथ कई पृष्ठों पर वॉटरमार्क लगा सकता हूँ?** हाँ—एक ही कॉल में सभी पृष्ठों पर वॉटरमार्क लागू करें.
+- **क्या प्रक्रिया मेमोरी‑कुशल है?** API पृष्ठों को स्ट्रीम करता है, इसलिए 500‑पृष्ठीय डायग्राम भी 200 MB RAM से कम में रहता है.
+
+## जावा में डायग्राम पृष्ठों पर वॉटरमार्किंग क्या है?
+यह जावा लाइब्रेरी का उपयोग करके प्रत्येक डायग्राम फ़ाइल (जैसे Visio, SVG, या अन्य समर्थित फ़ॉर्मैट) के प्रत्येक पृष्ठ पर अर्ध‑पारदर्शी टेक्स्ट (या छवियां) को प्रोग्रामेटिक रूप से ओवरले करने को शामिल करता है। वॉटरमार्क दृश्य सामग्री का हिस्सा बन जाता है, जिससे यह किसी भी व्यूअर में दिखाई देता है जबकि मूल डायग्राम डेटा संरक्षित रहता है।
+
+## GroupDocs.Watermark for Java का उपयोग क्यों करें?
+GroupDocs.Watermark **50+ इनपुट और आउटपुट फ़ॉर्मैट** का समर्थन करता है, **1 GB** तक की फ़ाइलों को पूरी दस्तावेज़ को मेमोरी में लोड किए बिना प्रोसेस करता है, और मौजूदा वॉटरमार्क का पता लगाने के लिए **बिल्ट‑इन OCR** प्रदान करता है। ये मापनीय क्षमताएं बड़े‑पैमाने के डायग्राम रिपॉज़िटरी के लिए तेज़, विश्वसनीय सुरक्षा सुनिश्चित करती हैं, जबकि इसका API जावा एप्लिकेशन में एकीकरण को सरल बनाता है।
+
+## पूर्वापेक्षाएँ
+- **Java Development Kit (JDK)** 8 या उससे ऊपर आपके मशीन पर स्थापित होना चाहिए.
+- **IntelliJ IDEA** या **Eclipse** जैसे IDE का उपयोग जावा कोड को संपादित और चलाने के लिए करें.
+- डिपेंडेंसी प्रबंधन के लिए Maven की बुनियादी जानकारी.
+
+### आवश्यक लाइब्रेरी और डिपेंडेंसीज़
+हम GroupDocs.Watermark for Java का उपयोग करेंगे, जिसे आप अपने Maven प्रोजेक्ट में जोड़ सकते हैं:
+
+```xml
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+यदि आप मैनुअल सेटअप पसंद करते हैं, तो आधिकारिक रिलीज़ पेज [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/) से बाइनरीज़ डाउनलोड करें और उन्हें अपने प्रोजेक्ट की क्लासपाथ में जोड़ें।
+
+### लाइसेंस प्राप्ति
+एक मुफ्त ट्रायल के साथ शुरू करें, अस्थायी लाइसेंस प्राप्त करने के लिए [GroupDocs.Trial Licensing](https://purchase.groupdocs.com/temporary-license/) पर जाएँ। प्रोडक्शन उपयोग के लिए, पूर्ण लाइसेंस खरीदें और `license.json` फ़ाइल को उस स्थान पर रखें जहाँ आपका एप्लिकेशन इसे पढ़ सके:
+
+```java
+// Load the temporary or purchased license – keep unchanged
+```java
+License license = new License();
+license.setLicense("path/to/license/file");
+```
+```
+
+## कार्यान्वयन गाइड
+नीचे एक चरण‑दर‑चरण मार्गदर्शिका है जो दिखाती है कि कैसे एक टेक्स्ट वॉटरमार्क को प्रत्येक डायग्राम पृष्ठ में एम्बेड किया जाए।
+
+### मैं एक डायग्राम पृष्ठ पर टेक्स्ट वॉटरमार्क कैसे जोड़ूँ?
+डायग्राम लोड करें, एक `TextWatermark` ऑब्जेक्ट बनाएं, इसे इच्छित पृष्ठों पर लागू करें, और अंत में आउटपुट सहेजें। यह एंड‑टू‑एंड फ्लो केवल चार संक्षिप्त API कॉल्स की आवश्यकता रखता है और सामान्य 10‑पृष्ठीय फ़ाइलों के लिए एक सेकंड से कम समय में चलता है, जबकि फ़ॉन्ट, रंग, अपारदर्शिता, और घूर्णन को अनुकूलित करने की अनुमति देता है।
+
+#### चरण 1: अपना डायग्राम लोड करें
+DiagramLoadOptions लाइब्रेरी को बताता है कि डायग्राम फ़ाइलों को कैसे पढ़ा जाए, जैसे पासवर्ड संभालना या विशिष्ट फ़ॉर्मैट विकल्प। सबसे पहले, `DiagramLoadOptions` के साथ एक `Watermarker` इंस्टैंसिएट करें। यह ऑब्जेक्ट मेमोरी में स्रोत डायग्राम को दर्शाता है।
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### चरण 2: टेक्स्ट वॉटरमार्क को इनिशियलाइज़ करें
+`TextWatermark` दृश्यमान टेक्स्ट, फ़ॉन्ट, रंग, और घूर्णन को परिभाषित करता है। आप वॉटरमार्क को सूक्ष्म बनाने के लिए अपारदर्शिता भी सेट कर सकते हैं।
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### चरण 3: डायग्राम पृष्ठों पर वॉटरमार्क जोड़ें
+DiagramShapeWatermarkOptions निर्धारित करता है कि वॉटरमार्क को डायग्राम शैप्स पर कैसे लागू किया जाए। DiagramWatermarkPlacementType यह निर्दिष्ट करता है कि वॉटरमार्क अग्रभूमि में दिखेगा या पृष्ठभूमि में। वॉटरमार्क को सभी पृष्ठभूमि पृष्ठों (या कस्टम पेज रेंज) पर लागू करें। API प्रत्येक पृष्ठ को स्ट्रीम करता है, इसलिए बड़े फ़ाइलों के लिए भी मेमोरी उपयोग कम रहता है।
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### चरण 4: सहेजें और बंद करें
+वॉटरमार्क किए गए डायग्राम को नई फ़ाइल में सहेजें और संसाधनों को रिलीज़ करें।
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### सामान्य समस्याएँ और समाधान
+- **फ़ाइल पाथ समस्याएँ:** पूर्ण पाथ का उपयोग करें या सत्यापित करें कि कार्य निर्देशिका आपके डायग्राम फ़ाइलों के स्थान से मेल खाती है.
+- **संस्करण असंगतता:** GroupDocs.Watermark रिलीज़ विशिष्ट JDK संस्करणों से जुड़ी होती हैं; सुनिश्चित करें कि आप संगत JDK 8‑17 बिल्ड का उपयोग कर रहे हैं.
+- **प्रदर्शन बाधाएँ:** बैच प्रोसेसिंग के लिए, एक ही `Watermarker` इंस्टेंस को पुन: उपयोग करें और बैच समाप्त होने के बाद ही `close()` कॉल करें.
+
+## व्यावहारिक अनुप्रयोग
+टेक्स्ट वॉटरमार्क कई वास्तविक‑दुनिया परिदृश्यों में उपयोगी होते हैं:
+1. **दस्तावेज़ सुरक्षा** – प्रतिस्पर्धियों को स्वामित्व वाले डायग्राम को पुनः उपयोग करने से रोकें.
+2. **ब्रांड सुदृढ़ीकरण** – कंपनी का नाम या स्लोगन सीधे प्रत्येक पृष्ठ पर एम्बेड करें.
+3. **सहयोग ट्रैकिंग** – उपयोगकर्ता के प्रारंभिक अक्षर या टाइमस्टैम्प जोड़ें जिससे पता चले कि किसने डायग्राम संपादित किया.
+
+## प्रदर्शन विचार
+- **मेमोरी प्रबंधन:** लाइब्रेरी पृष्ठों को लेज़ीली प्रोसेस करती है; हमेशा `watermarker.close()` को कॉल करके नेटिव रिसोर्सेज़ को मुक्त करें.
+- **वॉटरमार्क आकार:** बड़े फ़ॉन्ट आकार प्रोसेसिंग समय को रैखिक रूप से बढ़ाते हैं; 12‑pt फ़ॉन्ट पढ़ने योग्यता और गति के लिए अच्छा संतुलन है.
+- **बैच परीक्षण:** हजारों फ़ाइलों पर स्केल करने से पहले एक प्रतिनिधि नमूने पर वॉटरमार्किंग रूटीन चलाएँ.
+
+## निष्कर्ष
+अब आपके पास **डायग्राम में वॉटरमार्क कैसे जोड़ें** पृष्ठों पर टेक्स्ट के साथ जावा में GroupDocs.Watermark का उपयोग करके एक पूर्ण, प्रोडक्शन‑रेडी विधि है। यह क्षमता न केवल आपके दृश्य संपत्तियों को सुरक्षित करती है बल्कि सभी साझा किए गए डायग्राम में ब्रांड स्थिरता को भी सुदृढ़ करती है।
+
+### अगले कदम
+- अतिरिक्त दृश्य ब्रांडिंग के लिए इमेज वॉटरमार्क का अन्वेषण करें.
+- मल्टी‑लेयर सुरक्षा के लिए टेक्स्ट और इमेज वॉटरमार्क को मिलाएँ.
+- डायग्राम सुरक्षा को स्वचालित करने के लिए वॉटरमार्किंग फ्लो को अपने CI/CD पाइपलाइन में एकीकृत करें.
+
+## अक्सर पूछे जाने वाले प्रश्न
+1. **क्या मैं GroupDocs.Watermark को अन्य फ़ाइल फ़ॉर्मैट्स के लिए उपयोग कर सकता हूँ?**
+ हाँ—PDF, DOCX, PPTX, और SVG सहित 50 से अधिक फ़ॉर्मैट समर्थित हैं.
+
+2. **मैं कितने वॉटरमार्क जोड़ सकता हूँ, इसमें कोई सीमा है?**
+ कोई कठोर सीमा नहीं है, लेकिन प्रति पृष्ठ 10 से अधिक जोड़ने से रेंडरिंग गति प्रभावित हो सकती है.
+
+3. **डायग्राम से वॉटरमार्क कैसे हटाएँ?**
+ मौजूदा वॉटरमार्क को खोजने और हटाने के लिए `Watermarker.removeWatermarks()` API का उपयोग करें.
+
+4. **क्या मैं केवल विशिष्ट पृष्ठों को लक्षित कर सकता हूँ?**
+ बिल्कुल—`WatermarkOptions` को पेज रेंज या कस्टम प्रेडिकेट के साथ कॉन्फ़िगर करें.
+
+5. **यदि वॉटरमार्क दिखाई नहीं दे रहा है तो क्या करें?**
+ अपारदर्शिता, रंग कंट्रास्ट, और घूर्णन सेटिंग्स की जाँच करें; समस्या निवारण के लिए API दस्तावेज़ देखें.
+
+### अतिरिक्त प्रश्न‑उत्तर
+**प्र: क्या लाइब्रेरी पासवर्ड‑सुरक्षित डायग्राम का समर्थन करती है?**
+उ: हाँ—फ़ाइल लोड करते समय पासवर्ड को `DiagramLoadOptions` में पास करें.
+
+**प्र: क्या मैं इसे हेडलेस सर्वर पर चला सकता हूँ?**
+उ: API पूरी तरह से सर्वर‑साइड है और किसी GUI घटक की आवश्यकता नहीं है.
+
+**प्र: कौन से जावा संस्करण आधिकारिक रूप से समर्थित हैं?**
+उ: Java 8 से लेकर Java 17 तक परीक्षणित और दस्तावेज़ित हैं.
+
+**प्र: GroupDocs.Watermark बड़े फ़ाइलों को कैसे संभालता है?**
+उ: यह पृष्ठों को स्ट्रीम करता है, जिससे 1 GB डायग्राम के लिए भी अधिकतम मेमोरी उपयोग 200 MB से कम रहता है.
+
+**प्र: सहेजने से पहले वॉटरमार्क का पूर्वावलोकन कैसे देखें?**
+उ: किसी भी पृष्ठ का प्रीव्यू बिटमैप बनाने के लिए `Watermarker.getResultImage()` का उपयोग करें.

+Java में आरेख छवियों को बदलना मतलब प्रोग्रामेटिक रूप से एक आरेख फ़ाइल (जैसे .vsdx, .drawio, या .svg) के भीतर बिटमैप ग्राफिक्स वाली शैप्स को ढूँढना और उन एम्बेडेड छवियों को GroupDocs.Watermark API का उपयोग करके नई छवियों से बदलना है। यह उन अपडेट्स को स्वचालित करता है जो अन्यथा आरेख संपादक में मैन्युअल संपादन की आवश्यकता होती।
+
+## आरेख छवि प्रतिस्थापन के लिए GroupDocs.Watermark का उपयोग क्यों करें?
+GroupDocs.Watermark **50+ इनपुट और आउटपुट फ़ॉर्मैट्स** का समर्थन करता है – जिसमें Visio, Draw.io, और SVG शामिल हैं – और **फ़ाइलों को 500 MB तक** बिना पूरे दस्तावेज़ को मेमोरी में लोड किए प्रोसेस कर सकता है, जिससे आपको **CPU उपयोग में 30 % की कमी** मिलती है, जो साधारण फ़ाइल‑स्ट्रीम तरीकों की तुलना में बेहतर है।
+
+## पूर्वापेक्षाएँ
+- JDK 8 या नया स्थापित हो।
+- Java विकास के लिए एक IDE (IntelliJ IDEA, Eclipse, या VS Code)।

+
+## Java में आरेख छवियों को चरण-दर-चरण कैसे बदलें
+
+### डायग्राम फ़ाइल के लिए Watermarker को कैसे प्रारम्भ करें?
+Watermarker मुख्य क्लास है जो दस्तावेज़ का प्रतिनिधित्व करता है और सामग्री हेरफेर के लिए मेथड्स प्रदान करता है। शुरू करने के लिए, एक `Watermarker` ऑब्जेक्ट बनाएं जो डायग्राम फ़ाइल को मेमोरी में लोड करता है। `Watermarker` क्लास GroupDocs.Watermark का मुख्य एंट्री पॉइंट है, जिससे आप दस्तावेज़ पढ़, संशोधित, और सहेज सकते हैं। `DiagramLoadOptions` का उपयोग फ़ॉर्मेट‑विशिष्ट सेटिंग्स जैसे DPI या पेज रेंज निर्दिष्ट करने के लिए करें। `DiagramLoadOptions` निर्धारित करता है कि डायग्राम कैसे लोड किया जाता है, जैसे DPI या लोड मोड सेट करना।
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### शैप्स को खोजने के लिए डायग्राम सामग्री तक कैसे पहुँचें?
+फ़ाइल लोड करने के बाद, `Watermarker` से एक `DiagramContent` ऑब्जेक्ट प्राप्त करें। `DiagramContent` डायग्राम की पेजों और शैप्स की आंतरिक पदानुक्रम को दर्शाता है। यह मॉडल पेजों और शैप्स के संग्रह को उजागर करता है जिन्हें आप इटररेट कर सकते हैं, जिससे छवियों या टेक्स्ट जैसे विशिष्ट तत्वों को ढूँढना आसान हो जाता है।
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### डायग्राम में शैप छवियों को कैसे बदलें?
+वांछित पेज पर प्रत्येक `DiagramShape` के माध्यम से लूप करें, जांचें कि शैप में छवि है या नहीं, और छवि बाइट्स को नई फ़ाइल के बाइट्स से बदलें। `DiagramShape` डायग्राम में व्यक्तिगत शैप का मॉडल है, जबकि `DiagramWatermarkableImage` वह छवि डेटा संग्रहीत करता है जिसे शैप पर लागू किया जा सकता है।
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### परिवर्तनों को सहेजें और Watermarker को बंद कैसे करें?
+जब सभी संशोधन पूर्ण हो जाएँ, तो अपडेटेड डायग्राम को फ़ाइल में लिखने के लिए `Watermarker` पर `save` कॉल करें, फिर नेटीव संसाधनों को रिलीज़ करने के लिए `close` को बुलाएँ। यह सुनिश्चित करता है कि फ़ाइल हैंडल मुक्त हो जाएँ और मेमोरी लीक से बचा जा सके, विशेष रूप से जब बैच जॉब में कई डायग्राम प्रोसेस किए जा रहे हों।
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+
+public class FeatureSaveAndCloseWatermarker {
+ public static void run(Watermarker watermarker) throws Exception {
+ String outputPath = "YOUR_OUTPUT_DIRECTORY/output.vsdx";
+ watermarker.save(outputPath);
+ watermarker.close();
+ }
+}
+```
+```
+
+## एक ही डायग्राम में वॉटरमार्क जोड़ना (वैकल्पिक)
+
+यदि आपको डायग्राम को ब्रांड करना भी आवश्यक है, तो आप छवि प्रतिस्थापन से पहले या बाद में वॉटरमार्क जोड़ सकते हैं:
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+
+## सामान्य समस्याएँ और समस्या निवारण
+
+| लक्षण | संभावित कारण | समाधान |
+|---------|--------------|-----|
+| कोड चलाने के बाद कोई छवि परिवर्तन नहीं हुआ | `DiagramShape.hasImage()` ने false लौटाया | शैप प्रकार की जाँच करें; कुछ वेक्टर शैप्स छवियों को अलग तरीके से संग्रहीत करते हैं। |
+| बड़ी फ़ाइलों पर OutOfMemoryError | डायग्राम को एक बार में पूरी लोड करना | पृष्ठों को क्रमिक रूप से प्रोसेस करने के लिए `DiagramLoadOptions.setLoadMode(LoadMode.Stream)` का उपयोग करें। |
+| वॉटरमार्क दिखाई नहीं दे रहा | वॉटरमार्क मौजूदा सामग्री के पीछे रखा गया | सहेजने से पहले `watermarker.setWatermarkPosition(Position.Foreground)` कॉल करें। |
+
+## अक्सर पूछे जाने वाले प्रश्न
+
+**Q: क्या मैं पासवर्ड‑सुरक्षित डायग्राम में छवियों को बदल सकता हूँ?**
+A: हाँ। `Watermarker` बनाते समय पासवर्ड को `DiagramLoadOptions` में पास करें।
+
+**Q: क्या लाइब्रेरी .drawio (XML) फ़ाइलों के साथ काम करती है?**
+A: बिल्कुल – GroupDocs.Watermark Draw.io XML फ़ॉर्मेट का समर्थन करता है और प्रत्येक नोड को शैप मानता है।
+
+**Q: मैं समानांतर में कितने डायग्राम प्रोसेस कर सकता हूँ?**
+A: लाइब्रेरी पढ़ने‑के‑लिए थ्रेड‑सेफ़ है; लिखने‑के‑लिए, फ़ाइल‑हैंडल संघर्ष से बचने के लिए समवर्तीता को CPU कोर की संख्या तक सीमित रखें।
+
+**Q: छवि आकार पर कोई सीमा है?**
+A: 100 MB तक की छवियों का समर्थन किया जाता है; बड़े फ़ाइलों को पहले री‑साइज़ करना चाहिए ताकि मेमोरी उपयोग कम रहे।
+
+**Q: कौन से लाइसेंस विकल्प उपलब्ध हैं?**
+A: आप मुफ्त 30‑दिन के ट्रायल से शुरू कर सकते हैं; उत्पादन उपयोग के लिए भुगतान वाला लाइसेंस आवश्यक है, जिसे GroupDocs स्टोर से प्राप्त किया जा सकता है।

+# GroupDocs.Watermark के साथ बौद्धिक संपदा आरेखों की सुरक्षा करें
+
+बौद्धिक संपदा आरेखों की सुरक्षा किसी भी संगठन के लिए एक महत्वपूर्ण कदम है जो डिज़ाइन एसेट्स, फ्लोचार्ट या आर्किटेक्चर ड्रॉइंग्स साझा करता है। GroupDocs.Watermark for Java के साथ आप प्रोग्रामेटिक रूप से आरेख फ़ाइलें (जैसे `.vsdx`) लोड कर सकते हैं, इमेज वॉटरमार्क इंस्टेंस का पता लगा सकते हैं, टेक्स्ट वॉटरमार्क खोज सकते हैं, और मूल ड्रॉइंग को भ्रष्ट किए बिना उन्हें सुरक्षित रूप से हटा सकते हैं। यह ट्यूटोरियल आपको पूरी प्रक्रिया के माध्यम से ले जाता है—पर्यावरण सेटअप से लेकर बड़े आरेख लाइब्रेरीज़ के बैच‑प्रोसेसिंग तक—ताकि आप अपने Java एप्लिकेशन में सीधे मजबूत IP सुरक्षा एम्बेड कर सकें।
+
+## त्वरित उत्तर
+- **कौन सी लाइब्रेरी आरेख वॉटरमार्क को संभालती है?** GroupDocs.Watermark for Java.
+- **क्या मैं इमेज वॉटरमार्क के साथ टेक्स्ट भी detect कर सकता हूँ?** हाँ, the API provides `ImageDctHashSearchCriteria` for image detection and `TextSearchCriteria` for text.
+- **क्या कोड चलाने के लिए मुझे व्यावसायिक लाइसेंस की आवश्यकता है?** एक ट्रायल लाइसेंस विकास के लिए काम करता है; उत्पादन के लिए एक पेड लाइसेंस आवश्यक है।
+- **क्या बैच प्रोसेसिंग समर्थित है?** बिल्कुल—एक फ़ोल्डर पर लूप करें और प्रत्येक फ़ाइल पर समान वॉटरमार्क लॉजिक लागू करें।
+- **क्या हटाने के बाद मूल आरेख लेआउट अपरिवर्तित रहेगा?** लाइब्रेरी केवल वॉटरमार्क ऑब्जेक्ट्स को साफ़ करती है, सभी शैप्स, कनेक्टर्स और फ़ॉर्मेटिंग को संरक्षित रखती है।
+
+## बौद्धिक संपदा आरेख क्या हैं?
+बौद्धिक संपदा आरेख दृश्य प्रतिनिधित्व होते हैं—जैसे फ्लोचार्ट, UML मॉडल, नेटवर्क स्कीमैटिक, या आर्किटेक्चरल ड्रॉइंग्स—जो किसी व्यक्ति या संगठन के स्वामित्व वाले स्वामित्व जानकारी को समाहित करते हैं। ये आरेख अक्सर गोपनीय प्रक्रियाओं, डिज़ाइनों या रणनीतियों को दर्शाते हैं, जिससे वे अनधिकृत कॉपी, वितरण या परिवर्तन से बचाने के लिए मूल्यवान संपत्तियां बन जाते हैं। इन्हें बौद्धिक संपदा के रूप में मानकर आप कानूनी और तकनीकी सुरक्षा उपाय, जैसे वॉटरमार्किंग, लागू कर सकते हैं ताकि उनके उपयोग और प्रसार पर नियंत्रण बना रहे।
+
+## GroupDocs.Watermark for Java का उपयोग क्यों करें?
+GroupDocs.Watermark **50+ इनपुट और आउटपुट फ़ॉर्मैट्स** (जैसे `.vsdx`, `.vdx`, `.vsx`) का समर्थन करता है और पूरे फ़ाइल को मेमोरी में लोड किए बिना सैकड़ों‑पृष्ठों वाले आरेखों को प्रोसेस कर सकता है, जिससे RAM उपयोग में **70 %** तक की कमी आती है, तुलना में साधारण फ़ाइल‑स्ट्रीम तरीकों के। API में बिल्ट‑इन OCR‑फ़्री इमेज‑हैश तुलना भी उपलब्ध है, जिससे **200 ms** से कम समय में `detect image watermark` ऑपरेशन संभव होता है, एक सामान्य 2.5 GHz सर्वर पर।
+
+## पूर्वापेक्षाएँ

+
+## Watermarker को कैसे इनिशियलाइज़ करें?
+Creating a `Watermarker` instance is the first step in any watermark workflow. The `Watermarker` class loads a diagram file into memory and provides methods for searching, adding, and removing watermarks. By passing the diagram path and optional `DiagramLoadOptions`, you obtain an object that serves as the central point for all subsequent operations, ensuring consistent handling of the document throughout the process.
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## आरेख दस्तावेज़ को कैसे लोड करें?
+Loading a diagram with `DiagramLoadOptions` gives you fine‑grained control over how the file is parsed. `DiagramLoadOptions` lets you specify whether to load only visible pages, whether to preserve hidden layers, and how to handle embedded fonts. Adjusting these options can dramatically improve performance for large diagrams and ensures that only the necessary parts of the file are processed, reducing memory usage and speeding up watermark detection.
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## आरेख में इमेज वॉटरमार्क कैसे detect करें?
+Detecting image watermarks relies on the `ImageDctHashSearchCriteria` class, which computes a perceptual hash of a reference image and compares it against every embedded image in the diagram. This method is fast and tolerant of minor visual variations, allowing you to locate logos or other graphic watermarks even if they have been resized or slightly altered. By configuring the similarity threshold, you can balance detection sensitivity against false‑positive matches.
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## टेक्स्ट वॉटरमार्क कैसे खोजें?
+Searching for text watermarks uses the `TextSearchCriteria` class. This class scans all textual layers within the diagram, including those inside shapes, connectors, and groupings, and returns any matches that contain the specified string or pattern. The search is case‑insensitive by default and can be refined with regular expressions, enabling you to locate watermarks that may be rotated, partially hidden, or embedded in complex diagram structures.
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## आरेख से वॉटरमार्क कैसे हटाएँ?
+Removing watermarks is performed by invoking the `clear()` method on each `Watermark` object returned by a search operation. The `clear()` method deletes only the visual watermark elements while leaving the underlying diagram objects—such as shapes, connectors, and formatting—intact. After clearing, you save the document using the `save` method, producing a clean version of the diagram that retains its original layout and functionality.
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## व्यावहारिक अनुप्रयोग
+- **Enterprise software integration:** वॉटरमार्क वैधता को दस्तावेज़‑प्रबंधन सिस्टम में एम्बेड करें ताकि IP नीतियों को स्वचालित रूप से लागू किया जा सके।
+- **Content management systems (CMS):** प्रकाशित करने से पहले उपयोगकर्ता‑अपलोडेड आरेखों को अनधिकृत लोगो के लिए स्कैन करें।
+- **Legal document handling:** साक्ष्य बंडल तैयार करते समय गोपनीय वॉटरमार्क को detect और हटाएँ।
+
+## सामान्य समस्याएँ और ट्रबलशूटिंग
+- **Missing license exception:** सुनिश्चित करें कि ट्रायल या पेड लाइसेंस फ़ाइल को `License.setLicense("license_path")` के माध्यम से सही ढंग से संदर्भित किया गया है।
+- **Large diagram slowdown:** `loadOptions.setLoadHiddenLayers(false)` को सक्षम करें और आरेखों को पैरेलल स्ट्रीम्स में प्रोसेस करने पर विचार करें।
+- **False‑positive image matches:** आकस्मिक मैचों को कम करने के लिए `criteria.setSimilarityThreshold(0.85)` के साथ DCT हैश टॉलरेंस को समायोजित करें।
+
+## अक्सर पूछे जाने वाले प्रश्न
+
+**Q: क्या मैं एक ही कॉल में टेक्स्ट और इमेज दोनों वॉटरमार्क खोज सकता हूँ?**
+A: हाँ, `OrSearchCriteria` के साथ मानदंडों को संयोजित करें (जैसे, `new OrSearchCriteria(textCriteria, imageCriteria)`) ताकि दोनों प्रकार एक साथ प्राप्त हों।
+
+**Q: क्या वॉटरमार्क हटाने से आरेख लेआउट भ्रष्ट हो जाएगा?**
+A: नहीं। लाइब्रेरी वॉटरमार्क ऑब्जेक्ट्स को अलग करती है, इसलिए `clear()` के बाद शैप्स, कनेक्टर्स और फ़ॉर्मेटिंग अपरिवर्तित रहती है।
+
+**Q: कौन से आरेख फ़ॉर्मैट्स समर्थित हैं?**
+A: GroupDocs.Watermark `.vsdx`, `.vdx`, `.vsx` और कई पुराने Visio फ़ॉर्मैट्स को संभालता है, कुल मिलाकर **30** से अधिक आरेख प्रकारों को कवर करता है।
+
+**Q: मैं हजारों आरेखों को प्रभावी ढंग से कैसे प्रोसेस करूँ?**
+A: Java के `ExecutorService` का उपयोग करके वॉटरमार्क detection/removal को पैरेलल बैच में चलाएँ, और ओवरहेड कम करने के लिए एक ही `Watermarker` कॉन्फ़िगरेशन ऑब्जेक्ट को पुन: उपयोग करें।
+
+**Q: क्या इसे CI/CD पाइपलाइन में इंटीग्रेट करना संभव है?**
+A: बिल्कुल। Java स्निपेट्स को अपने बिल्ड स्क्रिप्ट्स (Maven/Gradle) में जोड़ें और उन्हें प्री‑डिप्लॉयमेंट वेरिफिकेशन स्टेप के रूप में चलाएँ ताकि यह सुनिश्चित हो सके कि कोई प्रतिबंधित वॉटरमार्क मौजूद न हो।

+# 如何在 Java 中為圖表頁面添加文字浮水印
+
+在現代軟件項目中，保護您分享的視覺資產——尤其是圖表——已成為首要任務。**How to watermark diagram** 在 Java 中使用文字浮水印是公司需要保留品牌識別、防止未經授權使用以及追蹤文件來源的常見需求。本教程將使用 **GroupDocs.Watermark for Java**，從環境準備到最終驗證，完整說明整個流程，讓您能自信地保護圖表。
+
+## 快速解答
+- **哪個函式庫可添加浮水印？** GroupDocs.Watermark for Java.
+- **需要哪個 Java 版本？** JDK 8 或更新版本。
+- **測試是否需要授權？** 免費的臨時授權可用於評估。
+- **可以一次為多個頁面添加浮水印嗎？** 可以——在一次呼叫中將浮水印套用至所有頁面。
+- **此過程記憶體效能如何？** API 會串流頁面，即使是 500 頁的圖表也能保持在 200 MB 以內的記憶體使用。
+
+## 在 Java 中為圖表頁面添加浮水印是什麼？
+它是指使用 Java 函式庫，以程式方式在圖表檔案（如 Visio、SVG 或其他支援格式）的每一頁上覆蓋半透明的文字（或圖像）。浮水印會成為視覺內容的一部分，於任何檢視器中皆可見，同時保留原始圖表資料。
+
+## 為什麼使用 GroupDocs.Watermark for Java？
+GroupDocs.Watermark 支援 **50 多種輸入與輸出格式**，可處理高達 **1 GB** 的檔案而無需將整個文件載入記憶體，並提供 **內建 OCR** 以偵測現有浮水印。這些具體功能確保對大型圖表庫提供快速且可靠的保護，同時其 API 簡化了在 Java 應用程式中的整合。
+
+## 前置條件
+- **Java Development Kit (JDK)** 8 或更高版本已安裝於您的機器上。
+- 具備如 **IntelliJ IDEA** 或 **Eclipse** 等 IDE，以編輯與執行 Java 程式碼。
+- 具備 Maven 依賴管理的基本認識。
+
+### 必要的函式庫與相依性
+我們將使用 GroupDocs.Watermark for Java，您可以將其加入 Maven 專案：
+
+```xml
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+如果您偏好手動設定，請從官方發行頁面 [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/) 下載二進位檔，並將其加入專案的 classpath。
+
+### 取得授權
+先透過 [GroupDocs.Trial Licensing](https://purchase.groupdocs.com/temporary-license/) 取得臨時授權以開始免費試用。正式使用時，請購買完整授權，並將 `license.json` 檔案放置於應用程式可讀取的位置：
+
+```java
+// Load the temporary or purchased license – keep unchanged
+```java
+License license = new License();
+license.setLicense("path/to/license/file");
+```
+```
+
+## 實作指南
+以下是逐步說明，展示如何將文字浮水印嵌入圖表的每一頁。
+
+### 如何為圖表頁面添加文字浮水印？
+載入圖表，建立 `TextWatermark` 物件，將其套用至目標頁面，最後儲存輸出。此端對端流程僅需四個簡潔的 API 呼叫，對於一般 10 頁檔案執行時間不到一秒，同時支援字型、顏色、不透明度與旋轉角度的自訂。
+
+#### 步驟 1：載入圖表
+DiagramLoadOptions 告訴函式庫如何讀取圖表檔案，例如處理密碼或特定格式選項。首先，以 `DiagramLoadOptions` 建立 `Watermarker` 實例。此物件在記憶體中代表來源圖表。
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### 步驟 2：初始化文字浮水印
+`TextWatermark` 定義可見的文字、字型、顏色與旋轉。您亦可設定不透明度，使浮水印更為淡化。
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### 步驟 3：將浮水印加入圖表頁面
+DiagramShapeWatermarkOptions 設定浮水印在圖表形狀上的套用方式。DiagramWatermarkPlacementType 指定浮水印是顯示於前景還是背景。將浮水印套用至所有背景頁面（或自訂頁面範圍）。API 會串流每一頁，因此即使是大型檔案，記憶體使用仍保持低位。
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### 步驟 4：儲存並關閉
+將加了浮水印的圖表持久化為新檔案，並釋放資源。
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### 常見問題與解決方案
+- **檔案路徑問題：** 使用絕對路徑或確認工作目錄與圖表檔案所在位置相符。
+- **版本不匹配：** GroupDocs.Watermark 的發行版與特定 JDK 版本相對應；請確保使用相容的 JDK 8‑17 版本。
+- **效能瓶頸：** 批次處理時，重複使用單一 `Watermarker` 實例，並於批次完成後才呼叫 `close()`。
+
+## 實務應用
+文字浮水印在許多實務情境中都很有用：
+1. **文件安全** – 防止競爭對手重新利用專有圖表。
+2. **品牌強化** – 將公司名稱或口號直接嵌入每一頁。
+3. **協作追蹤** – 加入使用者縮寫或時間戳記，以標示誰編輯了圖表。
+
+## 效能考量
+- **記憶體管理：** 函式庫以延遲方式處理頁面；務必呼叫 `watermarker.close()` 以釋放原生資源。
+- **浮水印大小：** 較大的字型會線性增加處理時間；12 點字型在可讀性與速度間取得良好平衡。
+- **批次測試：** 在擴展至上千檔案前，先於具代表性的樣本上執行浮水印流程。
+
+## 結論
+您現在已掌握使用 GroupDocs.Watermark 在 Java 中為圖表頁面添加文字浮水印的完整、可投入生產的方式。此功能不僅保護您的視覺資產，亦加強所有共享圖表的品牌一致性。
+
+### 後續步驟
+- 探索圖像浮水印，以增添視覺品牌元素。
+- 結合文字與圖像浮水印，實現多層保護。
+- 將浮水印流程整合至 CI/CD 管線，自動化圖表安全。
+
+## 常見問答
+1. **我可以將 GroupDocs.Watermark 用於其他檔案格式嗎？**
+ 是的——支援超過 50 種格式，包括 PDF、DOCX、PPTX 與 SVG。
+2. **我可以添加多少個浮水印？**
+ 沒有硬性上限，但每頁超過 10 個可能影響渲染速度。
+3. **如何從圖表中移除浮水印？**
+ 使用 `Watermarker.removeWatermarks()` API 來偵測並刪除現有浮水印。
+4. **我可以只針對特定頁面嗎？**
+ 當然可以——透過設定 `WatermarkOptions` 的頁面範圍或自訂條件。
+5. **如果浮水印看不見該怎麼辦？**
+ 檢查不透明度、顏色對比度與旋轉設定；參考 API 文件進行故障排除。
+
+### 其他問答
+**Q: 函式庫支援受密碼保護的圖表嗎？**
+A: 支援——在載入檔案時將密碼傳遞給 `DiagramLoadOptions`。
+

+# 使用 GroupDocs.Watermark 在 Java 中取代圖表圖像
+
+手動在圖表檔案中更新圖像既耗時又容易出錯。在本教學中，您將學會如何僅用幾行程式碼 **在 Java 中取代圖表圖像**，同時也會看到在需要時 **為圖表加入浮水印** 的方法。完成後，您將擁有一段可直接放入任何使用 Visio、Draw.io 或其他支援圖表格式的 Java 專案的可重用程式碼片段。
+
+## 快速解答
+- **什麼程式庫負責圖表圖像取代？** GroupDocs.Watermark for Java.
+- **基本取代需要多少行程式碼？** 只需在建立 Watermarker 後的三行程式碼。
+- **我可以同時加入浮水印嗎？** 可以 – 使用相同的 Watermarker 實例搭配浮水印物件。
+- **需要哪個 Java 版本？** JDK 8 或更高。
+- **生產環境需要授權嗎？** 需要有效的 GroupDocs.Watermark 授權；可使用免費試用版。
+
+## 什麼是 Java 圖表圖像取代？
+在 Java 中取代圖表圖像指的是以程式方式在圖表檔案（如 .vsdx、.drawio 或 .svg）中尋找包含位圖圖形的形狀，並使用 GroupDocs.Watermark API 將這些內嵌圖像換成新圖像。此方式可自動化原本需要在圖表編輯器中手動編輯的更新工作。
+
+## 為什麼使用 GroupDocs.Watermark 進行圖表圖像取代？
+GroupDocs.Watermark 支援 **超過 50 種輸入與輸出格式**，包括 Visio、Draw.io 與 SVG，且可在不將整個文件載入記憶體的情況下處理 **最高 500 MB 的檔案**，相較於傳統檔案串流方式可減少 **30 % 的 CPU 使用率**。
+
+## 前置條件
+- 已安裝 JDK 8 或更新版本。
+- Java 開發的 IDE（IntelliJ IDEA、Eclipse 或 VS Code）。
+- Maven（或手動加入 JAR 的能力）。
+- 有效的 GroupDocs.Watermark 授權（試用或永久）。可從 [GroupDocs](https://purchase.groupdocs.com/temporary-license/) 取得授權。
+
+### 必要的函式庫、版本與相依性
+將 GroupDocs.Watermark 的儲存庫與相依性加入您的 `pom.xml`：
+
+```xml
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+如果您偏好手動管理 JAR，請從官方網站下載最新發行版： [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/)。
+
+## 如何在 Java 中逐步取代圖表圖像
+
+### 如何為圖表檔案初始化 Watermarker？
+Watermarker 是代表文件並提供內容操作方法的主要類別。首先，建立一個 `Watermarker` 物件將圖表檔案載入記憶體。`Watermarker` 類別是 GroupDocs.Watermark 的核心入口，允許您讀取、修改與儲存文件。使用 `DiagramLoadOptions` 可指定格式特定的設定，例如 DPI 或頁面範圍。`DiagramLoadOptions` 會設定圖表的載入方式，例如 DPI 或載入模式。
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### 如何存取圖表內容以定位圖形？
+載入檔案後，從 `Watermarker` 取得 `DiagramContent` 物件。`DiagramContent` 代表圖表內部的頁面與圖形層級結構。此模型會公開頁面與圖形的集合，讓您可以遍歷，輕鬆定位圖像或文字等特定元素。
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### 如何在圖表中取代圖形圖像？
+遍歷目標頁面的每個 `DiagramShape`，檢查該圖形是否包含圖像，若有則以新檔案的位元組取代圖像。`DiagramShape` 是圖表中單一圖形的模型，而 `DiagramWatermarkableImage` 則儲存可套用於圖形的圖像資料。
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### 如何儲存變更並關閉 Watermarker？
+完成所有修改後，呼叫 `Watermarker` 的 `save` 方法將更新後的圖表寫入檔案，然後呼叫 `close` 釋放原生資源。這可確保檔案句柄被釋放，避免在批次處理大量圖表時產生記憶體洩漏。
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+
+public class FeatureSaveAndCloseWatermarker {
+ public static void run(Watermarker watermarker) throws Exception {
+ String outputPath = "YOUR_OUTPUT_DIRECTORY/output.vsdx";
+ watermarker.save(outputPath);
+ watermarker.close();
+ }
+}
+```
+```
+
+## 為相同圖表加入浮水印（可選）
+
+如果您也需要為圖表加上品牌標記，可在圖像取代前或之後加入浮水印：
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+
+## 常見陷阱與疑難排解
+
+| 症狀 | 可能原因 | 解決方法 |
+|---------|--------------|-----|
+| 執行程式碼後圖像未變更 | `DiagramShape.hasImage()` 回傳 false | 確認圖形類型；某些向量圖形以不同方式儲存圖像。 |
+| 大型檔案發生 OutOfMemoryError | 一次載入整個圖表 | 使用 `DiagramLoadOptions.setLoadMode(LoadMode.Stream)` 以逐頁串流方式處理。 |
+| 浮水印未顯示 | 浮水印被放在現有內容之後 | 在儲存前呼叫 `watermarker.setWatermarkPosition(Position.Foreground)`。 |
+
+## 常見問答
+
+**問：我可以取代受密碼保護的圖表圖像嗎？**
+答：可以。建立 `Watermarker` 時，將密碼傳入 `DiagramLoadOptions`。
+
+**問：此程式庫支援 .drawio（XML）檔案嗎？**
+答：當然支援 – GroupDocs.Watermark 支援 Draw.io XML 格式，並將每個節點視為圖形。
+
+**問：我可以平行處理多少個圖表？**
+答：程式庫對唯讀操作是執行緒安全的；寫入操作時，請將併發數限制在 CPU 核心數，以避免檔案句柄衝突。
+
+**問：圖像大小有上限嗎？**
+答：支援最高 100 MB 的圖像；較大的檔案請事先調整大小，以降低記憶體使用。
+
+**問：有哪些授權方案可供選擇？**
+答：可先使用 30 天免費試用；正式使用需購買授權，可從 GroupDocs 商店取得。

+ question: Can I search for both text and image watermarks in a single call?
+ - answer: No. The library isolates watermark objects, so shapes, connectors, and
+ formatting remain unchanged after `clear()`.
+ question: Will removing watermarks corrupt the diagram layout?
+ - answer: GroupDocs.Watermark handles `.vsdx`, `.vdx`, `.vsx`, and several older
+ Visio formats, covering over **30** diagram types.
+ question: Which diagram formats are supported?
+ - answer: Use Java’s `ExecutorService` to run watermark detection/removal in parallel
+ batches, and reuse a single `Watermarker` configuration object to reduce overhead.
+ question: How do I process thousands of diagrams efficiently?
+ - answer: Absolutely. Add the Java snippets to your build scripts (Maven/Gradle)
+ and run them as a pre‑deployment verification step to ensure no prohibited watermarks
+ are present.
+ question: Is it possible to integrate this into a CI/CD pipeline?

+
+# 保護智慧財產圖表與 GroupDocs.Watermark
+
+保護智慧財產圖表是任何分享設計資產、流程圖或建築圖紙的組織必須執行的關鍵步驟。使用 GroupDocs.Watermark for Java，您可以以程式方式載入圖表檔案（例如 `.vsdx`），偵測影像浮水印實例、搜尋文字浮水印，並在不損壞原始圖紙的前提下安全移除它們。本教學將帶您完成整個流程——從環境設定到批次處理大型圖表庫——讓您能將強大的智慧財產保護直接嵌入 Java 應用程式中。
+
+## 快速答案
+- **哪個函式庫處理圖表浮水印？** GroupDocs.Watermark for Java.
+- **我可以同時偵測影像浮水印與文字嗎？** 可以，API 提供 `ImageDctHashSearchCriteria` 用於影像偵測，`TextSearchCriteria` 用於文字。
+- **執行程式碼是否需要商業授權？** 試用授權可用於開發；正式環境需購買授權。
+- **是否支援批次處理？** 當然可以——遍歷資料夾，對每個檔案套用相同的浮水印邏輯。
+- **移除後原始圖表版面會保持完整嗎？** 函式庫僅清除浮水印物件，保留所有形狀、連接線與格式。
+
+## 什麼是智慧財產圖表？
+智慧財產圖表是指以視覺方式呈現的資料——例如流程圖、UML 模型、網路拓撲圖或建築圖紙——其中包含個人或組織擁有的專有資訊。這類圖表常傳遞機密的流程、設計或策略，因而成為需要防止未授權複製、散布或修改的寶貴資產。將它們視為智慧財產，即可採取法律與技術的保護措施，包括浮水印，以維持對其使用與散布的控制。
+
+## 為什麼使用 GroupDocs.Watermark for Java？
+GroupDocs.Watermark 支援 **50+** 輸入與輸出格式（包含 `.vsdx`、`.vdx`、`.vsx`），且可在不將整個檔案載入記憶體的情況下處理上百頁的圖表，將 RAM 使用量降低至 **70 %**，相較於傳統檔案串流方式更為有效。API 亦內建無需 OCR 的影像雜湊比較，能在一般 2.5 GHz 伺服器上於每張圖表 **200 ms** 內完成可靠的 `detect image watermark` 作業。
+
+## 前置條件
+在開始之前，請確保您已具備：
+
+1. **Java Development Kit (JDK) 8+** – 程式碼使用標準 Java 8 API。
+2. **IDE** – IntelliJ IDEA、Eclipse，或您慣用的任何編輯器。
+3. **GroupDocs.Watermark for Java** – 透過 Maven 或手動下載 JAR 取得。

+
+## 如何初始化 Watermarker？
+建立 `Watermarker` 實例是任何浮水印工作流程的第一步。`Watermarker` 類別會將圖表檔案載入記憶體，並提供搜尋、添加與移除浮水印的方法。只要傳入圖表路徑與可選的 `DiagramLoadOptions`，即可取得作為後續所有操作中心點的物件，確保文件在整個流程中得到一致處理。
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## 如何載入圖表文件？
+使用 `DiagramLoadOptions` 載入圖表可讓您精細控制檔案的解析方式。`DiagramLoadOptions` 允許您指定是否僅載入可見頁面、是否保留隱藏圖層，以及如何處理內嵌字型。調整這些選項可顯著提升大型圖表的效能，並確保僅處理必要的檔案部分，減少記憶體使用並加速浮水印偵測。
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## 如何在圖表中偵測影像浮水印？
+偵測影像浮水印依賴 `ImageDctHashSearchCriteria` 類別，該類別會計算參考影像的感知雜湊，並與圖表中每個嵌入影像進行比較。此方法快速且能容忍細微的視覺變化，讓您即使在影像被重新調整大小或稍作修改後仍能定位商標或其他圖形浮水印。透過設定相似度閾值，您可以在偵測靈敏度與誤報之間取得平衡。
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## 如何搜尋文字浮水印？
+搜尋文字浮水印使用 `TextSearchCriteria` 類別。此類別會掃描圖表內所有文字層，包括形狀、連接線與群組內的文字，並回傳任何包含指定字串或模式的匹配項目。預設情況下搜尋不區分大小寫，且可透過正規表達式進一步精煉，讓您能找出可能被旋轉、部分隱藏或嵌入於複雜圖表結構中的浮水印。
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## 如何從圖表中移除浮水印？
+移除浮水印的方式是對搜尋結果回傳的每個 `Watermark` 物件呼叫 `clear()` 方法。`clear()` 只會刪除視覺上的浮水印元素，並保留底層的圖表物件——如形狀、連接線與格式——不受影響。清除後，使用 `save` 方法儲存文件，即可得到保留原始版面與功能的乾淨圖表版本。
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## 實務應用
+- **企業軟體整合：** 將浮水印驗證嵌入文件管理系統，自動執行智慧財產政策。
+- **內容管理系統 (CMS)：** 在發布前掃描使用者上傳的圖表，檢測未授權的商標。
+- **法律文件處理：** 在製作證據包時偵測並剝除機密浮水印。
+
+## 常見陷阱與疑難排解
+- **缺少授權例外：** 確認已透過 `License.setLicense("license_path")` 正確引用試用或付費授權檔。
+- **大型圖表效能下降：** 啟用 `loadOptions.setLoadHiddenLayers(false)`，並考慮使用平行串流處理圖表。
+- **影像誤報匹配：** 使用 `criteria.setSimilarityThreshold(0.85)` 調整 DCT 雜湊容忍度，以減少意外匹配。
+
+## 常見問與答
+
+**Q: 我可以在一次呼叫中同時搜尋文字與影像浮水印嗎？**
+A: 可以，將條件以 `OrSearchCriteria` 結合（例如 `new OrSearchCriteria(textCriteria, imageCriteria)`）即可一次取得兩種結果。
+
+**Q: 移除浮水印會破壞圖表版面嗎？**
+A: 不會。函式庫會將浮水印物件隔離，`clear()` 後形狀、連接線與格式皆保持不變。
+
+**Q: 支援哪些圖表格式？**
+A: GroupDocs.Watermark 支援 `.vsdx`、`.vdx`、`.vsx` 以及多種舊版 Visio 格式，涵蓋超過 **30** 種圖表類型。
+
+**Q: 如何有效處理數千個圖表？**
+A: 使用 Java 的 `ExecutorService` 以平行批次執行浮水印偵測/移除，並重複使用單一 `Watermarker` 設定物件以降低開銷。
+
+**Q: 能否將此整合至 CI/CD 流程？**
+A: 完全可以。將 Java 程式碼片段加入建置腳本（Maven/Gradle），於部署前執行驗證步驟，確保不存在禁止的浮水印。

+# Hogyan lehet szöveges vízjelet elhelyezni diagram oldalakra Java-ban
+
+A modern szoftverprojektekben a megosztott vizuális eszközök, különösen a diagramok védelme elsődleges prioritássá vált. A **How to watermark diagram** oldalak szöveggel Java-ban egy gyakori igény a vállalatok számára, amelyeknek meg kell őrizniük a márkaidentitást, meg kell akadályozniuk az illetéktelen újrafelhasználást, és nyomon kell követniük a dokumentum eredetét. Ez a bemutató végigvezeti Önt a teljes folyamaton a **GroupDocs.Watermark for Java** használatával, a környezet előkészítésétől a végső ellenőrzésig, hogy magabiztosan védhesse diagramjait.
+
+## Gyors válaszok
+- **Melyik könyvtár ad hozzá vízjeleket?** GroupDocs.Watermark for Java.
+- **Melyik Java verzió szükséges?** JDK 8 vagy újabb.
+- **Szükségem van licencre a teszteléshez?** Egy ingyenes ideiglenes licenc működik értékeléshez.
+- **Lehet egyszerre több oldalt vízjelezni?** Igen—alkalmazza a vízjelet az összes oldalra egyetlen hívásban.
+- **Memóriahatékony a folyamat?** Az API oldalakat streamel, így még 500‑oldalas diagramok is 200 MB RAM alatt maradnak.
+
+## Mi a diagram oldalak vízjelezése Java-ban?
+Ez magában foglalja a félig átlátszó szöveg (vagy képek) programozott átfedését egy diagramfájl minden oldalára – például Visio, SVG vagy más támogatott formátum – egy Java könyvtár segítségével. A vízjel a vizuális tartalom részévé válik, így bármely megjelenítőben látható, miközben megőrzi az eredeti diagram adatait.
+
+## Miért használjuk a GroupDocs.Watermark for Java-t?
+A GroupDocs.Watermark **50+ bemeneti és kimeneti formátumot** támogat, **1 GB**-ig terjedő fájlokat dolgoz fel anélkül, hogy a teljes dokumentumot memóriába töltené, és **beépített OCR**-t kínál a meglévő vízjelek felismeréséhez. Ezek a számszerű képességek gyors, megbízható védelmet biztosítanak a nagyméretű diagramtárak számára, miközben az API egyszerűsíti a Java alkalmazásokba való integrációt.
+
+## Előfeltételek
+- **Java Development Kit (JDK)** 8 vagy újabb telepítve a gépén.
+- Egy IDE, például **IntelliJ IDEA** vagy **Eclipse** a Java kód szerkesztéséhez és futtatásához.
+- Alapvető ismeretek a Maven használatáról a függőségkezeléshez.
+
+### Szükséges könyvtárak és függőségek
+A GroupDocs.Watermark for Java-t fogjuk használni, amelyet hozzáadhat a Maven projektjéhez:
+
+```xml
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Ha a kézi beállítást részesíti előnyben, töltse le a bináris fájlokat a hivatalos kiadási oldalról [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/), és adja hozzá a projekt osztályútvonalához.
+
+### Licenc beszerzése
+Kezdje egy ingyenes próbaverzióval, ideiglenes licencet szerezve a [GroupDocs.Trial Licensing](https://purchase.groupdocs.com/temporary-license/) oldalról. Termelésben való használathoz vásároljon teljes licencet, és helyezze el a `license.json` fájlt olyan helyre, ahonnan az alkalmazás olvashatja:
+
+```java
+// Load the temporary or purchased license – keep unchanged
+```java
+License license = new License();
+license.setLicense("path/to/license/file");
+```
+```
+
+## Implementációs útmutató
+Az alábbi lépésről‑lépésre útmutató pontosan bemutatja, hogyan ágyazhat be szöveges vízjelet a diagram minden oldalára.
+
+### Hogyan adhatok szöveges vízjelet egy diagram oldalához?
+Töltse be a diagramot, hozza létre a `TextWatermark` objektumot, alkalmazza a kívánt oldalakon, majd végül mentse el a kimenetet. Ez az vég‑végi folyamat csak négy tömör API‑hívást igényel, és tipikus 10‑oldalas fájlok esetén egy másodpercnél gyorsabban fut, miközben lehetővé teszi a betűtípus, szín, átlátszóság és forgatás testreszabását.
+
+#### 1. lépés: töltse be a diagramot
+A DiagramLoadOptions megmondja a könyvtárnak, hogyan olvassa be a diagramfájlokat, például jelszavak vagy egyedi formátumbeállítások kezelése esetén. Először hozzon létre egy `Watermarker` példányt `DiagramLoadOptions`‑szal. Ez az objektum a forrásdiagramot reprezentálja a memóriában.
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### 2. lépés: inicializálja a szöveges vízjelet
+`TextWatermark` határozza meg a látható szöveget, betűtípust, színt és forgatást. Átlátszóságot is beállíthat a vízjel finomabbá tételéhez.
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### 3. lépés: adja hozzá a vízjelet a diagram oldalakhoz
+A DiagramShapeWatermarkOptions beállítja, hogyan kerül a vízjel a diagram alakzatokra. A DiagramWatermarkPlacementType meghatározza, hogy a vízjel az előtérben vagy a háttérben jelenik meg. Alkalmazza a vízjelet az összes háttéroldalra (vagy egy egyéni oldaltartományra). Az API minden oldalt streamel, így a memóriahasználat nagy fájlok esetén is alacsony marad.
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### 4. lépés: mentés és bezárás
+Mentse el a vízjelezett diagramot egy új fájlba, és szabadítsa fel az erőforrásokat.
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### Gyakori problémák és megoldások
+- **Fájlútvonal problémák:** Használjon abszolút útvonalakat, vagy ellenőrizze, hogy a munkakönyvtár megegyezik-e a diagramfájlok helyével.
+- **Verzióeltérések:** A GroupDocs.Watermark kiadások konkrét JDK verziókhoz vannak kötve; győződjön meg róla, hogy kompatibilis JDK 8‑17 buildet használ.
+- **Teljesítménybottleneckek:** Kötegelt feldolgozás esetén használja újra egyetlen `Watermarker` példányt, és csak a köteg befejezése után hívja meg a `close()` metódust.
+
+## Gyakorlati alkalmazások
+A szöveges vízjelek számos valós helyzetben hasznosak:
+
+1. **Dokumentumbiztonság** – Megakadályozza, hogy a versenytársak újra felhasználják a tulajdonosi diagramokat.
+2. **Márka megerősítése** – A cég nevét vagy szlogenjét közvetlenül minden oldalra ágyazza be.
+3. **Együttműködés nyomon követése** – Felhasználói monogramot vagy időbélyeget ad hozzá, hogy jelezze, ki szerkesztette a diagramot.
+
+## Teljesítmény szempontok
+- **Memóriakezelés:** A könyvtár lusta módon dolgozza fel az oldalakat; mindig hívja meg a `watermarker.close()`‑t a natív erőforrások felszabadításához.
+- **Vízjel mérete:** A nagyobb betűméretek lineárisan növelik a feldolgozási időt; egy 12‑pt betűméret jó egyensúlyt nyújt az olvashatóság és a sebesség között.
+- **Kötegelt tesztelés:** Futtassa a vízjelezési rutinot egy reprezentatív mintán, mielőtt több ezer fájlra skálázná.
+
+## Következtetés
+Most már rendelkezik egy teljes, termelésre kész módszerrel a **how to watermark diagram** oldalak szöveges vízjelezésére Java-ban a GroupDocs.Watermark segítségével. Ez a képesség nem csak a vizuális eszközeit védi, hanem erősíti a márka konzisztenciáját az összes megosztott diagramon.
+
+### Következő lépések
+- Fedezze fel a képi vízjeleket a további vizuális márkázás érdekében.
+- Kombinálja a szöveges és képi vízjeleket a több rétegű védelemhez.
+- Integrálja a vízjelezési folyamatot a CI/CD csővezetékébe a diagrambiztonság automatizálásához.
+

+# Diagram képek cseréje Java-ban a GroupDocs.Watermark használatával
+
+A diagramfájlokban lévő képek manuális frissítése időigényes és hibára hajlamos. Ebben az útmutatóban megtanulja, hogyan **cseréljen diagram képeket Java-ban** néhány kódsorral, és azt is megmutatjuk, hogyan **adhat hozzá vízjelet a diagramhoz** szükség esetén. A végére egy újrahasználható kódrészletet kap, amelyet bármely Java projekthez beilleszthet, amely Visio, Draw.io vagy más támogatott diagramformátumokkal dolgozik.
+
+## Gyors válaszok
+- **Melyik könyvtár kezeli a diagram képek cseréjét?** GroupDocs.Watermark for Java.
+- **Hány sor kódra van szükség egy alapvető cserehez?** Csak három sor a Watermarker létrehozása után.
+- **Hozzáadhatok vízjelet egyszerre?** Igen – használja ugyanazt a Watermarker példányt egy vízjel objektummal.
+- **Melyik Java verzió szükséges?** JDK 8 vagy újabb.
+- **Szükségem van licencre a termeléshez?** Érvényes GroupDocs.Watermark licenc szükséges; ingyenes próba elérhető.
+
+## Mi az a diagram képek cseréje Java-ban?
+A diagram képek cseréje Java-ban azt jelenti, hogy programozottan megtaláljuk azokat a formákat, amelyek bitmap grafikát tartalmaznak egy diagramfájlban (például .vsdx, .drawio vagy .svg), és ezeket a beágyazott képeket újakkal cseréljük a GroupDocs.Watermark API használatával. Ez automatizálja a frissítéseket, amelyek egyébként manuális szerkesztést igényelnének egy diagram szerkesztőben.
+
+## Miért használja a GroupDocs.Watermark-ot diagram képek cseréjéhez?
+A GroupDocs.Watermark **50+ bemeneti és kimeneti formátumot** támogat – beleértve a Visio, Draw.io és SVG formátumokat – és **akár 500 MB‑os fájlokat** képes feldolgozni anélkül, hogy a teljes dokumentumot a memóriába töltené, így **30 % CPU‑használat csökkenést** eredményez a naív fájl‑stream megközelítésekkel szemben.
+
+## Előfeltételek
+- JDK 8 vagy újabb telepítve.
+- IDE (IntelliJ IDEA, Eclipse vagy VS Code) a Java fejlesztéshez.
+- Maven (vagy a lehetőség, hogy a JAR-okat manuálisan adja hozzá).
+- Érvényes GroupDocs.Watermark licenc (próba vagy állandó). Licencet a [GroupDocs](https://purchase.groupdocs.com/temporary-license/) oldalról szerezhet.
+
+### Szükséges könyvtárak, verziók és függőségek
+Add the GroupDocs.Watermark repository and dependency to your `pom.xml`:
+
+```xml
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+If you prefer manual JAR management, download the latest release from the official site: [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/).
+
+## Hogyan cserélje ki a diagram képeket Java-ban lépésről lépésre
+
+### Hogyan inicializálja a Watermarker-t egy diagram fájlhoz?
+A Watermarker a fő osztály, amely egy dokumentumot képvisel és módszereket biztosít a tartalom manipulálásához. Kezdésként hozzon létre egy `Watermarker` objektumot, amely betölti a diagramfájlt a memóriába. A `Watermarker` osztály a GroupDocs.Watermark központi belépési pontja, lehetővé téve a dokumentumok olvasását, módosítását és mentését. Használja a `DiagramLoadOptions`‑t a formátumspecifikus beállítások, például DPI vagy oldaltartomány megadásához. A `DiagramLoadOptions` konfigurálja, hogyan töltődik be a diagram, például DPI vagy betöltési mód beállításával.
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### Hogyan érheti el a diagram tartalmát a formák megtalálásához?
+A fájl betöltése után szerezzen be egy `DiagramContent` objektumot a `Watermarker`‑ből. A `DiagramContent` a diagram belső hierarchiáját (oldalak és formák) képviseli. Ez a modell gyűjteményeket biztosít az oldalakról és formákról, amelyeken iterálhat, így könnyen megtalálhatja a képeket vagy szöveget tartalmazó elemeket.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### Hogyan cserélje le a formák képeit egy diagramon?
+Iteráljon végig minden `DiagramShape`‑on a kívánt oldalon, ellenőrizze, hogy a forma tartalmaz-e képet, és cserélje le a kép bájtjait egy új fájl bájtjaival. A `DiagramShape` egy egyedi forma modellje a diagramon, míg a `DiagramWatermarkableImage` tárolja a képadatokat, amelyeket egy formára lehet alkalmazni.
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### Hogyan mentse a módosításokat és zárja be a Watermarker-t?
+Amikor minden módosítás befejeződött, hívja meg a `save`‑t a `Watermarker`‑en, hogy az frissített diagramot egy fájlba írja, majd hívja meg a `close`‑t a natív erőforrások felszabadításához. Ez biztosítja, hogy a fájlkezelők felszabaduljanak, és megakadályozza a memória szivárgást, különösen nagy mennyiségű diagram kötegelt feldolgozása esetén.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+
+public class FeatureSaveAndCloseWatermarker {
+ public static void run(Watermarker watermarker) throws Exception {
+ String outputPath = "YOUR_OUTPUT_DIRECTORY/output.vsdx";
+ watermarker.save(outputPath);
+ watermarker.close();
+ }
+}
+```
+```
+
+## Vízjel hozzáadása ugyanahhoz a diagramhoz (opcionális)
+
+Ha a diagramot is márkázni szeretné, hozzáadhat egy vízjelet a képcsere előtt vagy után:
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+
+## Gyakori hibák és hibaelhárítás
+
+| Tünet | Valószínű ok | Megoldás |
+|---------|--------------|-----|
+| A kód futtatása után nem változik a kép | `DiagramShape.hasImage()` hamis értéket adott vissza | Ellenőrizze a forma típusát; egyes vektorformák másként tárolják a képeket. |
+| OutOfMemoryError nagy fájlok esetén | A teljes diagram egyszerre történő betöltése | Használja a `DiagramLoadOptions.setLoadMode(LoadMode.Stream)`-et az oldalak sorozatos feldolgozásához. |
+| A vízjel nem látható | A vízjel a meglévő tartalom mögött helyezkedik el | Hívja meg a `watermarker.setWatermarkPosition(Position.Foreground)`-t a mentés előtt. |
+
+## Gyakran feltett kérdések
+
+**Q: Cserélhetek képeket jelszóval védett diagramokban?**
+A: Igen. Adja meg a jelszót a `DiagramLoadOptions`-nek a `Watermarker` létrehozásakor.
+
+**Q: A könyvtár működik .drawio (XML) fájlokkal?**
+A: Teljesen – a GroupDocs.Watermark támogatja a Draw.io XML formátumot, és minden csomópontot formaként kezel.
+
+**Q: Hány diagramot dolgozhatok fel párhuzamosan?**
+A: A könyvtár szálbiztos csak olvasási műveletekhez; írási műveletek esetén korlátozza a párhuzamosságot a CPU‑magok számához, hogy elkerülje a fájlkezelő ütközéseket.
+
+**Q: Van korlátozás a kép méretére?**
+A: Legfeljebb 100 MB‑os képek támogatottak; nagyobb fájlokat előzetesen méretezze át a memóriahasználat alacsonyan tartása érdekében.
+
+**Q: Milyen licencelési lehetőségek állnak rendelkezésre?**
+A: Kezdhet egy ingyenes 30‑napos próbaidőszakkal; termelési használathoz fizetős licenc szükséges, amelyet a GroupDocs áruházból szerezhet be.

+# Szellemi tulajdon diagramok védelme a GroupDocs.Watermark segítségével
+
+A szellemi tulajdon diagramok védelme kritikus lépés minden olyan szervezet számára, amely tervezési eszközöket, folyamatábrákat vagy építészeti rajzokat oszt meg. A GroupDocs.Watermark for Java segítségével programozottan betöltheti a diagramfájlokat (például `.vsdx`), észlelheti a képi vízjelpéldányokat, kereshet szöveges vízjeleket, és biztonságosan eltávolíthatja azokat anélkül, hogy a eredeti rajzot megsértené. Ez az útmutató végigvezeti Önt a teljes folyamaton – a környezet beállításától a nagyméretű diagramkönyvtárak kötegelt feldolgozásáig – hogy közvetlenül Java‑alkalmazásaiba ágyazhassa a robusztus IP‑védelmet.
+
+## Gyors válaszok
+- **Melyik könyvtár kezeli a diagramok vízjeleit?** GroupDocs.Watermark for Java.
+- **Képes vagyok képi vízjelet és szövegeset is észlelni?** Igen, az API biztosítja az `ImageDctHashSearchCriteria`‑t a képek észleléséhez, valamint a `TextSearchCriteria`‑t a szöveghez.
+- **Szükség van kereskedelmi licencre a kód futtatásához?** A próbaverzió licenc fejlesztéshez működik; a termeléshez fizetett licenc szükséges.
+- **Támogatott a kötegelt feldolgozás?** Teljes mértékben – egyszerűen bejárhat egy mappát, és ugyanazt a vízjellogikát alkalmazhatja minden fájlra.
+- **A diagram eredeti elrendezése megmarad az eltávolítás után?** A könyvtár csak a vízjelobjektumokat törli, megőrizve az összes alakzatot, kapcsolatot és formázást.
+
+## Mi az a szellemi tulajdon diagram?
+A szellemi tulajdon diagramok vizuális ábrázolások – például folyamatábrák, UML‑modellek, hálózati vázlatok vagy építészeti rajzok –, amelyek olyan tulajdonosi információkat tartalmaznak, amelyeket egy egyén vagy szervezet birtokol. Ezek a diagramok gyakran bizalmas folyamatokat, terveket vagy stratégiákat közvetítenek, ezért értékes eszközök, amelyeket védeni kell az illetéktelen másolás, terjesztés vagy módosítás ellen. Szellemi tulajdonként kezelve jogi és technikai védelmet, köztük vízjelezést, alkalmazhat a felhasználás és terjesztés ellenőrzésére.
+
+## Miért használjuk a GroupDocs.Watermark for Java‑t?
+A GroupDocs.Watermark **50+ bemeneti és kimeneti formátumot** támogat (beleértve `.vsdx`, `.vdx`, `.vsx`‑t) és képes több száz oldalas diagramok feldolgozására anélkül, hogy a teljes fájlt a memóriába töltené, ezáltal a RAM‑használatot akár **70 %**‑kal csökkentve a hagyományos fájl‑stream megközelítésekhez képest. Az API beépített OCR‑mentes képhash‑összehasonlítást is kínál, lehetővé téve a megbízható `detect image watermark` műveleteket **200 ms**‑nél kevesebb idő alatt egy tipikus 2,5 GHz‑es szerveren.
+
+## Előfeltételek
+Mielőtt elkezdené, győződjön meg róla, hogy rendelkezik:
+
+1. **Java Development Kit (JDK) 8+** – a kód a standard Java 8 API‑kat használja.
+2. **IDE** – IntelliJ IDEA, Eclipse vagy bármely kedvenc szerkesztő.
+3. **GroupDocs.Watermark for Java** – Maven‑en vagy manuális JAR‑letöltésen keresztül.
+
+### Szükséges könyvtárak és függőségek
+A könyvtárat hozzáadhatja Maven‑en vagy közvetlenül letöltheti a JAR‑okat.
+
+#### Maven beállítás
+Adja hozzá a tárolót és a függőségi bejegyzéseket a `pom.xml` fájlhoz:
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+
+#### Közvetlen letöltés
+Ha a manuális telepítést részesíti előnyben, töltse le a legújabb kiadást a [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/) oldalról.
+
+### Licenc beszerzése
+- **Ingyenes próba:** Ideális az API képességeinek kiértékeléséhez.
+- **Ideiglenes licenc:** Rövid távú teszteléshez használható korlátozások nélkül.
+- **Vásárlás:** Szükséges a termelési környezethez és a prémium formátumok feloldásához.
+
+## Hogyan inicializáljuk a Watermarker‑t?
+A `Watermarker` példány létrehozása az első lépés minden vízjel‑munkafolyamatban. A `Watermarker` osztály betölti a diagramfájlt a memóriába, és módszereket biztosít a vízjelek keresésére, hozzáadására és eltávolítására. A diagram útvonalának és opcionális `DiagramLoadOptions`‑nek a megadásával egy olyan objektumot kap, amely a további műveletek központi pontjaként szolgál, biztosítva a dokumentum egységes kezelését a teljes folyamat során.
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## Hogyan töltsünk be egy diagramdokumentumot?
+A `DiagramLoadOptions` használatával finomhangolt vezérlést kap a fájl feldolgozásához. A `DiagramLoadOptions` lehetővé teszi, hogy meghatározza, csak a látható oldalakat töltse-e be, megőrizze‑e a rejtett rétegeket, illetve hogyan kezelje a beágyazott betűtípusokat. Ezeknek a beállításoknak a módosítása jelentősen javíthatja a nagy diagramok teljesítményét, és biztosítja, hogy csak a szükséges fájlrészek kerüljenek feldolgozásra, csökkentve a memóriahasználatot és felgyorsítva a vízjel‑észlelést.
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## Hogyan észleljük a képi vízjelet egy diagramon?
+A képi vízjelek észlelése az `ImageDctHashSearchCriteria` osztályra támaszkodik, amely egy referencia kép perceptuális hash‑ét számítja ki, majd összehasonlítja a diagramben beágyazott összes képpel. Ez a módszer gyors és toleráns a kisebb vizuális eltérésekre, lehetővé téve logók vagy egyéb grafikus vízjelek megtalálását még akkor is, ha azok átméreteződtek vagy enyhén módosultak. A hasonlósági küszöb beállításával egyensúlyba hozhatja az észlelés érzékenységét a hamis pozitív találatokkal szemben.
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## Hogyan keressünk szöveges vízjelekre?
+A szöveges vízjelek keresése a `TextSearchCriteria` osztályt használja. Ez az osztály bejárja a diagram összes szövegrétegét, beleértve az alakzatok, kapcsolók és csoportok belsejében lévőket, és visszaadja azokat a találatokat, amelyek tartalmazzák a megadott karakterláncot vagy mintát. A keresés alapértelmezés szerint nem érzékeny a kis‑ és nagybetűkre, és finomítható reguláris kifejezésekkel, így megtalálhatók a forgatott, részben rejtett vagy összetett diagramstruktúrákba ágyazott vízjelek.
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## Hogyan távolítsuk el a vízjeleket egy diagramról?
+A vízjelek eltávolítása a keresési művelet által visszaadott `Watermark` objektumok `clear()` metódusának meghívásával történik. A `clear()` csak a vizuális vízjelelemeket törli, míg az alapul szolgáló diagramobjektumok – például alakzatok, kapcsolók és formázás – érintetlenek maradnak. A törlés után a dokumentumot a `save` metódussal mentheti, így egy tiszta verziót kap, amely megőrzi az eredeti elrendezést és funkcionalitást.
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+

+- **Vállalati szoftverintegráció:** Vízjel‑ellenőrzés beágyazása dokumentumkezelő rendszerekbe az IP‑szabályzatok automatikus érvényesítéséhez.
+- **Tartalomkezelő rendszerek (CMS):** Felhasználók által feltöltött diagramok átvizsgálása jogosulatlan logók után a közzététel előtt.
+- **Jogi dokumentumkezelés:** Bizalmas vízjelek felismerése és eltávolítása bizonyítékcsomagok előkészítésekor.
+
+## Gyakori hibák és hibaelhárítás
+- **Hiányzó licenc kivétel:** Győződjön meg róla, hogy a próbaverzió vagy a fizetett licenc fájl helyesen van hivatkozva a `License.setLicense("license_path")` segítségével.
+- **Nagy diagramok lassulása:** Engedélyezze a `loadOptions.setLoadHiddenLayers(false)` beállítást, és fontolja meg a diagramok párhuzamos stream‑ekben történő feldolgozását.
+- **Hamisan pozitív képi egyezések:** Állítsa be a DCT‑hash toleranciát a `criteria.setSimilarityThreshold(0.85)` értékkel a véletlen egyezések csökkentése érdekében.
+
+## Gyakran feltett kérdések
+
+**K: Kereshetek egyszerre szöveges és képi vízjelekre?**
+V: Igen, kombinálhatja a kritériumokat az `OrSearchCriteria`‑vel (például `new OrSearchCriteria(textCriteria, imageCriteria)`) a két típus egyidejű lekérdezéséhez.
+
+**K: Az eltávolítás megsérti a diagram elrendezését?**
+V: Nem. A könyvtár csak a vízjelobjektumokat izolálja, így az alakzatok, kapcsolók és formázás változatlan marad a `clear()` után.
+
+**K: Mely diagramformátumok támogatottak?**
+V: A GroupDocs.Watermark kezeli a `.vsdx`, `.vdx`, `.vsx` és több régebbi Visio formátumot, összesen több mint **30** diagramtípust.
+
+**K: Hogyan dolgozzam fel hatékonyan több ezer diagramot?**
+V: Használja a Java `ExecutorService`‑t a vízjel‑észlelés/eltávolítás párhuzamos kötegekben történő futtatásához, és egyetlen `Watermarker` konfigurációs objektumot újrahasználva csökkentse a terhelést.
+
+**K: Integrálható ez CI/CD pipeline‑ba?**
+V: Teljes mértékben. Adja hozzá a Java‑kódrészleteket a build‑szkriptekhez (Maven/Gradle), és futtassa őket elő‑telepítési ellenőrzésként, hogy biztosítsa a tiltott vízjelek hiányát.

+# Cara menambahkan watermark teks pada halaman diagram dengan Java
+
+Dalam proyek perangkat lunak modern, melindungi aset visual yang Anda bagikan—terutama diagram—telah menjadi prioritas utama. **Cara menambahkan watermark pada diagram** dengan teks di Java adalah kebutuhan umum bagi perusahaan yang perlu mempertahankan identitas merek, mencegah penggunaan tidak sah, dan melacak asal dokumen. Tutorial ini memandu Anda melalui seluruh proses menggunakan **GroupDocs.Watermark for Java**, mulai dari persiapan lingkungan hingga verifikasi akhir, sehingga Anda dapat dengan yakin mengamankan diagram Anda.
+
+## Jawaban Cepat
+- **Perpustakaan apa yang menambahkan watermark?** GroupDocs.Watermark for Java.
+- **Versi Java mana yang diperlukan?** JDK 8 atau lebih baru.
+- **Apakah saya memerlukan lisensi untuk pengujian?** Lisensi sementara gratis dapat digunakan untuk evaluasi.
+- **Bisakah saya menambahkan watermark pada beberapa halaman sekaligus?** Ya—terapkan watermark ke semua halaman dalam satu panggilan.
+- **Apakah proses ini efisien memori?** API mem-stream halaman, sehingga bahkan diagram dengan 500 halaman tetap di bawah 200 MB RAM.
+
+## Apa itu watermark pada halaman diagram di Java?
+Ini melibatkan penimpalan teks (atau gambar) semi‑transparan secara programatik pada setiap halaman file diagram—seperti Visio, SVG, atau format lain yang didukung—menggunakan perpustakaan Java. Watermark menjadi bagian dari konten visual, sehingga terlihat di semua penampil sambil mempertahankan data diagram asli.
+
+## Mengapa menggunakan GroupDocs.Watermark untuk Java?
+GroupDocs.Watermark mendukung **lebih dari 50 format input dan output**, memproses file hingga **1 GB** tanpa memuat seluruh dokumen ke memori, dan menawarkan **OCR bawaan** untuk mendeteksi watermark yang sudah ada. Kemampuan terukur ini memastikan perlindungan yang cepat dan andal untuk repositori diagram berskala besar, sementara API-nya menyederhanakan integrasi ke dalam aplikasi Java.
+
+## Prasyarat
+- **Java Development Kit (JDK)** 8 atau lebih tinggi terpasang di mesin Anda.
+- IDE seperti **IntelliJ IDEA** atau **Eclipse** untuk mengedit dan menjalankan kode Java.
+- Familiaritas dasar dengan Maven untuk manajemen dependensi.
+
+### Perpustakaan dan dependensi yang diperlukan
+Kami akan menggunakan GroupDocs.Watermark untuk Java, yang dapat Anda tambahkan ke proyek Maven Anda:
+
+```xml
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Jika Anda lebih suka penyiapan manual, unduh binary dari halaman rilis resmi [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/) dan tambahkan ke classpath proyek Anda.
+
+### Akuisisi lisensi
+Mulailah dengan percobaan gratis dengan memperoleh lisensi sementara dari [GroupDocs.Trial Licensing](https://purchase.groupdocs.com/temporary-license/). Untuk penggunaan produksi, beli lisensi penuh dan letakkan file `license.json` di lokasi yang dapat dibaca aplikasi Anda:
+
+```java
+// Load the temporary or purchased license – keep unchanged
+```java
+License license = new License();
+license.setLicense("path/to/license/file");
+```
+```
+
+## Panduan Implementasi
+Berikut adalah panduan langkah demi langkah yang menunjukkan cara menyisipkan watermark teks ke setiap halaman diagram.
+
+### Bagaimana cara menambahkan watermark teks ke halaman diagram?
+Muat diagram, buat objek `TextWatermark`, terapkan ke halaman yang diinginkan, dan akhirnya simpan outputnya. Alur end‑to‑end ini hanya memerlukan empat panggilan API singkat dan berjalan dalam kurang dari satu detik untuk file 10‑halaman tipikal, sambil memungkinkan penyesuaian font, warna, opasitas, dan rotasi.
+
+#### Langkah 1: muat diagram Anda
+DiagramLoadOptions memberi tahu perpustakaan cara membaca file diagram, seperti menangani kata sandi atau opsi format tertentu. Pertama, buat instance `Watermarker` dengan `DiagramLoadOptions`. Objek ini mewakili diagram sumber dalam memori.
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### Langkah 2: inisialisasi watermark teks
+`TextWatermark` mendefinisikan teks yang terlihat, font, warna, dan rotasi. Anda juga dapat mengatur opasitas untuk membuat watermark lebih halus.
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### Langkah 3: tambahkan watermark ke halaman diagram
+DiagramShapeWatermarkOptions mengonfigurasi cara watermark diterapkan pada bentuk diagram. DiagramWatermarkPlacementType menentukan apakah watermark muncul di latar depan atau latar belakang. Terapkan watermark ke semua halaman latar belakang (atau rentang halaman khusus). API mem-stream setiap halaman, sehingga penggunaan memori tetap rendah bahkan untuk file besar.
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### Langkah 4: simpan dan tutup
+Simpan diagram yang telah diberi watermark ke file baru dan bebaskan sumber daya.
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### Masalah umum dan solusi
+- **Masalah jalur file:** Gunakan jalur absolut atau pastikan direktori kerja sesuai dengan lokasi file diagram Anda.
+- **Ketidaksesuaian versi:** Rilis GroupDocs.Watermark terikat pada versi JDK tertentu; pastikan Anda menggunakan build JDK 8‑17 yang kompatibel.
+- **Kendala kinerja:** Untuk pemrosesan batch, gunakan kembali satu instance `Watermarker` dan panggil `close()` hanya setelah batch selesai.
+
+## Aplikasi praktis
+Watermark teks berguna dalam banyak skenario dunia nyata:
+
+1. **Keamanan dokumen** – Mencegah pesaing menggunakan kembali diagram proprietari.
+2. **Penguatan merek** – Menyematkan nama perusahaan atau slogan langsung pada setiap halaman.
+3. **Pelacakan kolaborasi** – Tambahkan inisial pengguna atau cap waktu untuk menunjukkan siapa yang mengedit diagram.
+
+## Pertimbangan kinerja
+- **Manajemen memori:** Perpustakaan memproses halaman secara malas; selalu panggil `watermarker.close()` untuk membebaskan sumber daya native.
+- **Ukuran watermark:** Ukuran font yang lebih besar meningkatkan waktu pemrosesan secara linear; font 12‑pt merupakan keseimbangan yang baik antara keterbacaan dan kecepatan.
+- **Pengujian batch:** Jalankan rutin watermark pada sampel representatif sebelum memperluas ke ribuan file.
+
+## Kesimpulan
+Anda kini memiliki metode lengkap dan siap produksi untuk **cara menambahkan watermark pada diagram** dengan teks di Java menggunakan GroupDocs.Watermark. Kemampuan ini tidak hanya mengamankan aset visual Anda tetapi juga memperkuat konsistensi merek di semua diagram yang dibagikan.
+
+### Langkah selanjutnya
+- Jelajahi watermark gambar untuk branding visual tambahan.
+- Gabungkan watermark teks dan gambar untuk perlindungan berlapis.
+- Integrasikan alur watermark ke dalam pipeline CI/CD Anda untuk mengotomatisasi keamanan diagram.
+
+## Pertanyaan yang sering diajukan
+1. **Bisakah saya menggunakan GroupDocs.Watermark untuk format file lain?**
+ Ya—lebih dari 50 format, termasuk PDF, DOCX, PPTX, dan SVG, didukung.
+
+2. **Apakah ada batas berapa banyak watermark yang dapat saya tambahkan?**
+ Tidak ada batas keras, tetapi menambahkan lebih dari 10 per halaman dapat memengaruhi kecepatan rendering.
+
+3. **Bagaimana cara menghapus watermark dari diagram?**
+ Gunakan API `Watermarker.removeWatermarks()` untuk mendeteksi dan menghapus watermark yang ada.
+
+4. **Bisakah saya menargetkan halaman tertentu saja?**
+ Tentu—konfigurasikan `WatermarkOptions` dengan rentang halaman atau predikat khusus.
+
+5. **Apa yang harus saya lakukan jika watermark tidak terlihat?**
+ Periksa opasitas, kontras warna, dan pengaturan rotasi; lihat dokumentasi API untuk pemecahan masalah.
+
+### Tambahan Q&A
+**T: Apakah perpustakaan mendukung diagram yang dilindungi kata sandi?**
+**J:** Ya—lewatkan kata sandi ke `DiagramLoadOptions` saat memuat file.
+
+**T: Bisakah saya menjalankannya di server tanpa tampilan (headless)?**
+**J:** API sepenuhnya sisi server dan tidak memerlukan komponen GUI.
+
+**T: Versi Java mana yang secara resmi didukung?**
+**J:** Java 8 hingga Java 17 telah diuji dan didokumentasikan.
+
+**T: Bagaimana GroupDocs.Watermark menangani file besar?**
+**J:** Ia mem-stream halaman, menjaga penggunaan memori puncak di bawah 200 MB bahkan untuk diagram 1 GB.
+
+**T: Apakah ada cara untuk melihat pratinjau watermark sebelum menyimpan?**
+**J:** Gunakan `Watermarker.getResultImage()` untuk menghasilkan bitmap pratinjau dari halaman mana pun.

+# Ganti gambar diagram di Java menggunakan GroupDocs.Watermark
+
+Memperbarui gambar di dalam file diagram secara manual memakan waktu dan rawan kesalahan. Dalam tutorial ini Anda akan belajar cara **mengganti gambar diagram di Java** dengan hanya beberapa baris kode, dan Anda juga akan melihat cara **menambahkan watermark ke diagram** bila diperlukan. Pada akhir tutorial Anda akan memiliki potongan kode yang dapat digunakan kembali dan dapat dimasukkan ke dalam proyek Java apa pun yang bekerja dengan Visio, Draw.io, atau format diagram lain yang didukung.
+
+## Jawaban Cepat
+- **Library apa yang menangani penggantian gambar diagram?** GroupDocs.Watermark untuk Java.
+- **Berapa banyak baris kode yang diperlukan untuk penggantian dasar?** Hanya tiga baris setelah Watermarker dibuat.
+- **Bisakah saya menambahkan watermark sekaligus?** Ya – gunakan instance Watermarker yang sama dengan objek watermark.
+- **Versi Java apa yang diperlukan?** JDK 8 atau lebih tinggi.
+- **Apakah saya memerlukan lisensi untuk penggunaan produksi?** Lisensi GroupDocs.Watermark yang valid diperlukan; percobaan gratis tersedia.
+
+## Apa itu mengganti gambar diagram di Java?
+Mengganti gambar diagram di Java berarti secara programatis menemukan bentuk yang berisi grafik bitmap di dalam file diagram (seperti .vsdx, .drawio, atau .svg) dan menukar gambar yang tertanam tersebut dengan gambar baru menggunakan API GroupDocs.Watermark. Ini mengotomatiskan pembaruan yang sebaliknya memerlukan penyuntingan manual di editor diagram.
+
+## Mengapa menggunakan GroupDocs.Watermark untuk penggantian gambar diagram?
+GroupDocs.Watermark mendukung **lebih dari 50 format input dan output** – termasuk Visio, Draw.io, dan SVG – dan dapat memproses **file hingga 500 MB** tanpa memuat seluruh dokumen ke memori, memberikan **pengurangan penggunaan CPU sebesar 30 %** dibandingkan pendekatan aliran file yang sederhana.

+
+## Cara mengganti gambar diagram di Java langkah demi langkah
+
+### Bagaimana cara menginisialisasi Watermarker untuk file diagram?
+Watermarker adalah kelas utama yang mewakili dokumen dan menyediakan metode untuk manipulasi konten. Untuk memulai, buat objek `Watermarker` yang memuat file diagram ke memori. Kelas `Watermarker` adalah titik masuk inti GroupDocs.Watermark, memungkinkan Anda membaca, memodifikasi, dan menyimpan dokumen. Gunakan `DiagramLoadOptions` untuk menentukan pengaturan khusus format seperti DPI atau rentang halaman. `DiagramLoadOptions` mengonfigurasi cara diagram dimuat, misalnya mengatur DPI atau mode pemuatan.
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### Bagaimana cara mengakses konten diagram untuk menemukan bentuk?
+Setelah memuat file, ambil objek `DiagramContent` dari `Watermarker`. `DiagramContent` mewakili hierarki internal diagram berupa halaman dan bentuk. Model ini menampilkan koleksi halaman dan bentuk yang dapat Anda iterasi, memudahkan menemukan elemen spesifik seperti gambar atau teks.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### Bagaimana cara mengganti gambar bentuk dalam diagram?
+Lakukan perulangan pada setiap `DiagramShape` pada halaman yang diinginkan, periksa apakah bentuk tersebut berisi gambar, dan ganti byte gambar dengan byte file baru. `DiagramShape` adalah model untuk bentuk individual dalam diagram, sementara `DiagramWatermarkableImage` menyimpan data gambar yang dapat diterapkan pada bentuk.
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### Bagaimana cara menyimpan perubahan dan menutup Watermarker?
+Setelah semua modifikasi selesai, panggil `save` pada `Watermarker` untuk menulis diagram yang diperbarui ke file, lalu panggil `close` untuk melepaskan sumber daya native. Ini memastikan handle file dibebaskan dan mencegah kebocoran memori, terutama saat memproses banyak diagram dalam pekerjaan batch.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+
+public class FeatureSaveAndCloseWatermarker {
+ public static void run(Watermarker watermarker) throws Exception {
+ String outputPath = "YOUR_OUTPUT_DIRECTORY/output.vsdx";
+ watermarker.save(outputPath);
+ watermarker.close();
+ }
+}
+```
+```
+
+## Menambahkan watermark ke diagram yang sama (opsional)
+
+Jika Anda juga perlu memberi merek pada diagram, Anda dapat menambahkan watermark sebelum atau setelah penggantian gambar:
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+
+## Kesalahan umum dan pemecahan masalah
+
+| Gejala | Penyebab kemungkinan | Solusi |
+|---------|--------------|-----|
+| Tidak ada perubahan gambar setelah menjalankan kode | `DiagramShape.hasImage()` mengembalikan false | Verifikasi tipe bentuk; beberapa bentuk vektor menyimpan gambar secara berbeda. |
+| OutOfMemoryError pada file besar | Memuat seluruh diagram sekaligus | Gunakan `DiagramLoadOptions.setLoadMode(LoadMode.Stream)` untuk memproses halaman secara berurutan. |
+| Watermark tidak terlihat | Watermark ditempatkan di belakang konten yang ada | Panggil `watermarker.setWatermarkPosition(Position.Foreground)` sebelum menyimpan. |
+
+## Pertanyaan yang sering diajukan
+
+**Q: Bisakah saya mengganti gambar dalam diagram yang dilindungi kata sandi?**
+A: Ya. Berikan kata sandi ke `DiagramLoadOptions` saat membuat `Watermarker`.
+
+**Q: Apakah perpustakaan ini bekerja dengan file .drawio (XML)?**
+A: Tentu – GroupDocs.Watermark mendukung format XML Draw.io dan memperlakukan setiap node sebagai bentuk.
+
+**Q: Berapa banyak diagram yang dapat saya proses secara paralel?**
+A: Perpustakaan ini aman untuk thread pada operasi baca‑saja; untuk operasi tulis, batasi konkruensi hingga jumlah inti CPU untuk menghindari kontensi handle file.
+
+**Q: Apakah ada batas ukuran gambar?**
+A: Gambar hingga 100 MB didukung; file yang lebih besar harus diubah ukurannya terlebih dahulu untuk menjaga penggunaan memori tetap rendah.
+
+**Q: Opsi lisensi apa yang tersedia?**
+A: Anda dapat memulai dengan percobaan gratis selama 30 hari; penggunaan produksi memerlukan lisensi berbayar, yang dapat diperoleh dari toko GroupDocs.

+# Melindungi diagram properti intelektual dengan GroupDocs.Watermark
+
+Melindungi diagram properti intelektual adalah langkah penting bagi setiap organisasi yang berbagi aset desain, diagram alur, atau gambar arsitektur. Dengan GroupDocs.Watermark untuk Java Anda dapat memuat file diagram secara programatik (seperti `.vsdx`), mendeteksi instance watermark gambar, mencari watermark teks, dan menghapusnya dengan aman tanpa merusak gambar asli. Tutorial ini memandu Anda melalui seluruh proses—dari penyiapan lingkungan hingga pemrosesan batch perpustakaan diagram besar—sehingga Anda dapat menyematkan perlindungan IP yang kuat langsung ke dalam aplikasi Java Anda.
+
+## Jawaban Cepat
+- **Library mana yang menangani watermark diagram?** GroupDocs.Watermark for Java.
+- **Apakah saya dapat mendeteksi watermark gambar serta teks?** Ya, API menyediakan `ImageDctHashSearchCriteria` untuk deteksi gambar dan `TextSearchCriteria` untuk teks.
+- **Apakah saya memerlukan lisensi komersial untuk menjalankan kode?** Lisensi percobaan dapat digunakan untuk pengembangan; lisensi berbayar diperlukan untuk produksi.
+- **Apakah pemrosesan batch didukung?** Tentu—loop melalui folder dan terapkan logika watermark yang sama pada setiap file.
+- **Apakah tata letak diagram asli tetap utuh setelah penghapusan?** Library hanya menghapus objek watermark, mempertahankan semua bentuk, konektor, dan format.
+
+## Apa itu diagram properti intelektual?
+Diagram properti intelektual adalah representasi visual—seperti diagram alur, model UML, skema jaringan, atau gambar arsitektur—yang berisi informasi kepemilikan yang dimiliki oleh individu atau organisasi. Diagram ini sering menyampaikan proses, desain, atau strategi rahasia, menjadikannya aset berharga yang memerlukan perlindungan terhadap penyalinan, distribusi, atau perubahan tanpa izin. Dengan memperlakukan mereka sebagai properti intelektual, Anda dapat menerapkan perlindungan hukum dan teknis, termasuk watermarking, untuk menjaga kontrol atas penggunaan dan penyebarannya.
+
+## Mengapa menggunakan GroupDocs.Watermark untuk Java?
+GroupDocs.Watermark mendukung **lebih dari 50 format input dan output** (termasuk `.vsdx`, `.vdx`, `.vsx`) dan dapat memproses diagram ratusan halaman tanpa memuat seluruh file ke memori, mengurangi konsumsi RAM hingga **70 %** dibandingkan pendekatan aliran file naïf. API juga menawarkan perbandingan hash‑gambar tanpa OCR bawaan, memungkinkan operasi `detect image watermark` yang andal dalam waktu kurang dari **200 ms** per diagram pada server 2.5 GHz tipikal.
+
+## Prasyarat
+Sebelum memulai, pastikan Anda memiliki:
+
+1. **Java Development Kit (JDK) 8+** – kode menggunakan API standar Java 8.
+2. **IDE** – IntelliJ IDEA, Eclipse, atau editor apa pun yang Anda suka.
+3. **GroupDocs.Watermark untuk Java** – dapat melalui Maven atau unduhan JAR manual.
+
+### Perpustakaan dan dependensi yang diperlukan
+Anda dapat menambahkan perpustakaan melalui Maven atau mengunduh JAR secara langsung.
+
+#### Pengaturan Maven
+Tambahkan entri repositori dan dependensi ke file `pom.xml` Anda:
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+
+#### Unduhan langsung
+Jika Anda lebih suka instalasi manual, unduh rilis terbaru dari [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/).
+
+### Akuisisi lisensi
+- **Uji coba gratis:** Ideal untuk mengevaluasi kemampuan API.
+- **Lisensi sementara:** Digunakan untuk pengujian jangka pendek tanpa pembatasan fitur.
+- **Pembelian:** Diperlukan untuk penerapan produksi dan membuka format premium.
+
+## Cara menginisialisasi Watermarker?
+Membuat instance `Watermarker` adalah langkah pertama dalam setiap alur kerja watermark. Kelas `Watermarker` memuat file diagram ke memori dan menyediakan metode untuk mencari, menambah, dan menghapus watermark. Dengan memberikan path diagram dan opsional `DiagramLoadOptions`, Anda memperoleh objek yang berfungsi sebagai titik sentral untuk semua operasi selanjutnya, memastikan penanganan dokumen yang konsisten sepanjang proses.
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## Cara memuat dokumen diagram?
+Memuat diagram dengan `DiagramLoadOptions` memberi Anda kontrol terperinci tentang cara file diparsing. `DiagramLoadOptions` memungkinkan Anda menentukan apakah hanya memuat halaman yang terlihat, apakah mempertahankan lapisan tersembunyi, dan bagaimana menangani font yang disematkan. Menyesuaikan opsi-opsi ini dapat secara dramatis meningkatkan kinerja untuk diagram besar dan memastikan hanya bagian yang diperlukan dari file yang diproses, mengurangi penggunaan memori dan mempercepat deteksi watermark.
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## Cara mendeteksi watermark gambar dalam diagram?
+Mendeteksi watermark gambar bergantung pada kelas `ImageDctHashSearchCriteria`, yang menghitung hash perseptual dari gambar referensi dan membandingkannya dengan setiap gambar yang disematkan dalam diagram. Metode ini cepat dan toleran terhadap variasi visual kecil, memungkinkan Anda menemukan logo atau watermark grafis lainnya meskipun telah diubah ukuran atau sedikit dimodifikasi. Dengan mengonfigurasi ambang kesamaan, Anda dapat menyeimbangkan sensitivitas deteksi dengan kemungkinan positif palsu.
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## Cara mencari watermark teks?
+Mencari watermark teks menggunakan kelas `TextSearchCriteria`. Kelas ini memindai semua lapisan teks dalam diagram, termasuk yang berada di dalam bentuk, konektor, dan grup, serta mengembalikan kecocokan yang berisi string atau pola yang ditentukan. Pencarian bersifat tidak sensitif huruf besar/kecil secara default dan dapat diperkaya dengan ekspresi reguler, memungkinkan Anda menemukan watermark yang mungkin diputar, sebagian tersembunyi, atau disematkan dalam struktur diagram yang kompleks.
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## Cara menghapus watermark dari diagram?
+Menghapus watermark dilakukan dengan memanggil metode `clear()` pada setiap objek `Watermark` yang dikembalikan oleh operasi pencarian. Metode `clear()` menghapus hanya elemen visual watermark sementara meninggalkan objek diagram yang mendasarinya—seperti bentuk, konektor, dan format—tetap utuh. Setelah dibersihkan, Anda menyimpan dokumen menggunakan metode `save`, menghasilkan versi bersih diagram yang mempertahankan tata letak dan fungsionalitas aslinya.
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## Aplikasi praktis
+- **Integrasi perangkat lunak perusahaan:** Tanamkan validasi watermark ke dalam sistem manajemen dokumen untuk menegakkan kebijakan IP secara otomatis.
+- **Sistem manajemen konten (CMS):** Pindai diagram yang diunggah pengguna untuk logo tidak sah sebelum dipublikasikan.
+- **Penanganan dokumen hukum:** Deteksi dan hapus watermark rahasia saat menyiapkan paket bukti.
+
+## Kesulitan umum dan pemecahan masalah
+- **Pengecualian lisensi hilang:** Pastikan file lisensi percobaan atau berbayar direferensikan dengan benar melalui `License.setLicense("license_path")`.
+- **Penurunan kinerja pada diagram besar:** Aktifkan `loadOptions.setLoadHiddenLayers(false)` dan pertimbangkan memproses diagram dalam aliran paralel.
+- **Kecocokan gambar positif palsu:** Sesuaikan toleransi hash DCT dengan `criteria.setSimilarityThreshold(0.85)` untuk mengurangi kecocokan yang tidak diinginkan.
+
+## Pertanyaan yang sering diajukan
+
+**Q: Apakah saya dapat mencari kedua jenis watermark, teks dan gambar, dalam satu panggilan?**
+A: Ya, gabungkan kriteria dengan `OrSearchCriteria` (mis., `new OrSearchCriteria(textCriteria, imageCriteria)`) untuk mengambil kedua tipe sekaligus.
+
+**Q: Apakah menghapus watermark merusak tata letak diagram?**
+A: Tidak. Library mengisolasi objek watermark, sehingga bentuk, konektor, dan format tetap tidak berubah setelah `clear()`.
+
+**Q: Format diagram apa saja yang didukung?**
+A: GroupDocs.Watermark menangani `.vsdx`, `.vdx`, `.vsx`, dan beberapa format Visio lama, mencakup lebih dari **30** tipe diagram.
+
+**Q: Bagaimana cara memproses ribuan diagram secara efisien?**
+A: Gunakan `ExecutorService` Java untuk menjalankan deteksi/penghapusan watermark dalam batch paralel, dan gunakan satu objek konfigurasi `Watermarker` secara berulang untuk mengurangi overhead.
+
+**Q: Apakah memungkinkan mengintegrasikannya ke dalam pipeline CI/CD?**
+A: Tentu. Tambahkan cuplikan Java ke dalam skrip build Anda (Maven/Gradle) dan jalankan sebagai langkah verifikasi pra‑deployment untuk memastikan tidak ada watermark terlarang yang ada.

+# Come aggiungere filigrane di testo alle pagine di diagrammi in Java
+
+In progetti software moderni, proteggere le risorse visive che condividi—soprattutto i diagrammi—è diventata una priorità assoluta. **Come aggiungere filigrane a diagrammi** è una necessità comune per le aziende che devono preservare l'identità del brand, impedire il riutilizzo non autorizzato e tracciare la provenienza dei documenti. Questo tutorial ti guida attraverso l'intero processo usando **GroupDocs.Watermark for Java**, dalla preparazione dell'ambiente alla verifica finale, così potrai proteggere i tuoi diagrammi con sicurezza.
+
+## Risposte rapide
+- **Quale libreria aggiunge filigrane?** GroupDocs.Watermark for Java.
+- **Quale versione di Java è richiesta?** JDK 8 o successiva.
+- **Ho bisogno di una licenza per i test?** Una licenza temporanea gratuita funziona per la valutazione.
+- **Posso aggiungere filigrane a più pagine contemporaneamente?** Sì—applica la filigrana a tutte le pagine in una singola chiamata.
+- **Il processo è efficiente in termini di memoria?** L'API trasmette le pagine, quindi anche diagrammi di 500 pagine rimangono sotto i 200 MB di RAM.
+
+## Cos'è la filigrana delle pagine di diagrammi in Java?
+Consiste nel sovrapporre programmaticamente testo semi‑trasparente (o immagini) su ogni pagina di un file di diagramma—come Visio, SVG o altri formati supportati—utilizzando una libreria Java. La filigrana diventa parte del contenuto visivo, rendendola visibile in qualsiasi visualizzatore mantenendo intatti i dati originali del diagramma.
+
+## Perché usare GroupDocs.Watermark per Java?
+GroupDocs.Watermark supporta **50+ input and output formats**, elabora file fino a **1 GB** senza caricare l'intero documento in memoria e offre **built‑in OCR** per rilevare filigrane esistenti. Queste capacità quantificate garantiscono protezione rapida e affidabile per repository di diagrammi su larga scala, mentre la sua API semplifica l'integrazione nelle applicazioni Java.
+
+## Prerequisiti
+- **Java Development Kit (JDK)** 8 o superiore installato sulla tua macchina.
+- Un IDE come **IntelliJ IDEA** o **Eclipse** per modificare ed eseguire codice Java.
+- Familiarità di base con Maven per la gestione delle dipendenze.
+
+### Librerie e dipendenze richieste
+Useremo GroupDocs.Watermark for Java, che puoi aggiungere al tuo progetto Maven:
+
+```xml
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Se preferisci una configurazione manuale, scarica i binari dalla pagina ufficiale [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/) e aggiungili al classpath del tuo progetto.
+
+### Acquisizione della licenza
+Inizia con una prova gratuita ottenendo una licenza temporanea da [GroupDocs.Trial Licensing](https://purchase.groupdocs.com/temporary-license/). Per l'uso in produzione, acquista una licenza completa e posiziona il file `license.json` dove la tua applicazione può leggerlo:
+
+```java
+// Load the temporary or purchased license – keep unchanged
+```java
+License license = new License();
+license.setLicense("path/to/license/file");
+```
+```
+
+## Guida all'implementazione
+Di seguito trovi una procedura passo‑a‑passo che mostra esattamente come incorporare una filigrana di testo in ogni pagina di un diagramma.
+
+### Come aggiungere una filigrana di testo a una pagina di diagramma?
+Carica il diagramma, crea un oggetto `TextWatermark`, applicalo alle pagine desiderate e infine salva il risultato. Questo flusso end‑to‑end richiede solo quattro chiamate API concise e si completa in meno di un secondo per file tipici di 10 pagine, consentendo la personalizzazione di font, colore, opacità e rotazione.
+
+#### Passo 1: carica il tuo diagramma
+`DiagramLoadOptions` indica alla libreria come leggere i file di diagramma, gestendo password o opzioni di formato specifiche. Prima, istanzia un `Watermarker` con `DiagramLoadOptions`. Questo oggetto rappresenta il diagramma sorgente in memoria.
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### Passo 2: inizializza la filigrana di testo
+`TextWatermark` definisce il testo visibile, il font, il colore e la rotazione. Puoi anche impostare l'opacità per rendere la filigrana più discreta.
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### Passo 3: aggiungi la filigrana alle pagine del diagramma
+`DiagramShapeWatermarkOptions` configura come una filigrana viene applicata alle forme del diagramma. `DiagramWatermarkPlacementType` specifica se la filigrana appare in primo piano o sullo sfondo. Applica la filigrana a tutte le pagine di sfondo (o a un intervallo di pagine personalizzato). L'API trasmette ogni pagina, mantenendo basso l'uso di memoria anche per file di grandi dimensioni.
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### Passo 4: salva e chiudi
+Persisti il diagramma filigranato in un nuovo file e rilascia le risorse.
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### Problemi comuni e soluzioni
+- **Problemi di percorso file:** Usa percorsi assoluti o verifica che la directory di lavoro corrisponda alla posizione dei tuoi file di diagramma.
+- **Incompatibilità di versione:** Le versioni di GroupDocs.Watermark sono legate a specifiche versioni JDK; assicurati di usare una build JDK 8‑17 compatibile.
+- **Colli di bottiglia delle prestazioni:** Per l'elaborazione batch, riutilizza una singola istanza `Watermarker` e chiama `close()` solo al termine del batch.
+
+## Applicazioni pratiche
+I watermark di testo sono utili in molti scenari reali:
+
+1. **Sicurezza dei documenti** – Impedire ai concorrenti di riutilizzare diagrammi proprietari.
+2. **Rinforzo del brand** – Inserire il nome o lo slogan dell'azienda direttamente su ogni pagina.
+3. **Tracciamento della collaborazione** – Aggiungere le iniziali dell'utente o timestamp per indicare chi ha modificato il diagramma.
+
+## Considerazioni sulle prestazioni
+- **Gestione della memoria:** La libreria elabora le pagine in modo lazy; invoca sempre `watermarker.close()` per liberare le risorse native.
+- **Dimensione della filigrana:** Font più grandi aumentano il tempo di elaborazione linearmente; un font da 12 pt è un buon compromesso tra leggibilità e velocità.
+- **Test batch:** Esegui la routine di filigrana su un campione rappresentativo prima di scalare a migliaia di file.
+
+## Conclusione
+Ora disponi di un metodo completo, pronto per la produzione, per **come aggiungere filigrane a diagrammi** con testo in Java usando GroupDocs.Watermark. Questa funzionalità non solo protegge le tue risorse visive, ma rafforza anche la coerenza del brand su tutti i diagrammi condivisi.
+
+### Prossimi passi
+- Esplora le filigrane immagine per un ulteriore branding visivo.
+- Combina filigrane di testo e immagine per una protezione a più livelli.
+- Integra il flusso di filigrana nel tuo pipeline CI/CD per automatizzare la sicurezza dei diagrammi.
+
+## Domande frequenti
+1. **Posso usare GroupDocs.Watermark per altri formati di file?**
+ Sì—sono supportati oltre 50 formati, inclusi PDF, DOCX, PPTX e SVG.
+
+2. **Esiste un limite al numero di filigrane che posso aggiungere?**
+ Nessun limite rigido, ma aggiungere più di 10 filigrane per pagina può influire sulla velocità di rendering.
+
+3. **Come rimuovo una filigrana da un diagramma?**
+ Usa l'API `Watermarker.removeWatermarks()` per rilevare e cancellare le filigrane esistenti.
+
+4. **Posso mirare solo a pagine specifiche?**
+ Assolutamente—configura `WatermarkOptions` con un intervallo di pagine o un predicato personalizzato.
+
+5. **Cosa fare se la filigrana non è visibile?**
+ Verifica opacità, contrasto di colore e impostazioni di rotazione; consulta la documentazione API per la risoluzione dei problemi.
+
+### Domande aggiuntive
+**Q: La libreria supporta diagrammi protetti da password?**
+A: Sì—passa la password a `DiagramLoadOptions` durante il caricamento del file.
+
+**Q: Posso eseguire questo su un server headless?**
+A: L'API è completamente server‑side e non richiede componenti GUI.
+
+**Q: Quali versioni di Java sono ufficialmente supportate?**
+A: Java 8 fino a Java 17 sono testate e documentate.

+# Sostituire le immagini del diagramma in Java usando GroupDocs.Watermark
+
+Aggiornare manualmente le immagini all'interno dei file di diagramma richiede tempo e può generare errori. In questo tutorial imparerai come **sostituire le immagini del diagramma in Java** con poche righe di codice, e vedrai anche come **aggiungere una filigrana al diagramma** quando necessario. Alla fine avrai uno snippet riutilizzabile da inserire in qualsiasi progetto Java che lavori con Visio, Draw.io o altri formati di diagramma supportati.
+
+## Risposte rapide
+- **Quale libreria gestisce la sostituzione delle immagini del diagramma?** GroupDocs.Watermark for Java.
+- **Quante righe di codice sono necessarie per una sostituzione di base?** Solo tre righe dopo la creazione del Watermarker.
+- **Posso aggiungere una filigrana allo stesso tempo?** Sì – usa la stessa istanza di Watermarker con un oggetto filigrana.
+- **Quale versione di Java è richiesta?** JDK 8 o superiore.
+- **È necessaria una licenza per l'uso in produzione?** È richiesta una licenza valida di GroupDocs.Watermark; è disponibile una prova gratuita.
+
+## Cos'è la sostituzione delle immagini del diagramma in Java?
+Sostituire le immagini del diagramma in Java significa trovare programmaticamente le forme che contengono grafica bitmap all'interno di un file di diagramma (come .vsdx, .drawio o .svg) e scambiare quelle immagini incorporate con nuove utilizzando l'API di GroupDocs.Watermark. Questo automatizza gli aggiornamenti che altrimenti richiederebbero una modifica manuale in un editor di diagrammi.
+
+## Perché usare GroupDocs.Watermark per la sostituzione delle immagini del diagramma?
+GroupDocs.Watermark supporta **oltre 50 formati di input e output** – inclusi Visio, Draw.io e SVG – e può elaborare **file fino a 500 MB** senza caricare l'intero documento in memoria, fornendo una **riduzione del 30 % dell'utilizzo della CPU** rispetto agli approcci naïve di streaming dei file.
+
+## Prerequisiti
+- JDK 8 o versioni successive installato.
+- Un IDE (IntelliJ IDEA, Eclipse o VS Code) per lo sviluppo Java.
+- Maven (o la possibilità di aggiungere JAR manualmente).
+- Una licenza valida di GroupDocs.Watermark (trial o permanente). Puoi ottenere una licenza da [GroupDocs](https://purchase.groupdocs.com/temporary-license/).
+
+### Librerie, versioni e dipendenze richieste
+Aggiungi il repository e la dipendenza di GroupDocs.Watermark al tuo `pom.xml`:
+
+```xml
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Se preferisci gestire i JAR manualmente, scarica l'ultima versione dal sito ufficiale: [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/).
+
+## Come sostituire le immagini del diagramma in Java passo dopo passo
+
+### Come si inizializza il Watermarker per un file di diagramma?
+Watermarker è la classe principale che rappresenta un documento e fornisce metodi per la manipolazione del contenuto. Per iniziare, crea un oggetto `Watermarker` che carica il file di diagramma in memoria. La classe `Watermarker` è il punto di ingresso principale di GroupDocs.Watermark, consentendo di leggere, modificare e salvare i documenti. Usa `DiagramLoadOptions` per specificare impostazioni specifiche del formato, come DPI o intervallo di pagine. `DiagramLoadOptions` configura come viene caricato un diagramma, ad esempio impostando DPI o modalità di caricamento.
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### Come accedere al contenuto del diagramma per individuare le forme?
+Dopo aver caricato il file, recupera un oggetto `DiagramContent` dal `Watermarker`. `DiagramContent` rappresenta la gerarchia interna del diagramma di pagine e forme. Questo modello espone collezioni di pagine e forme che puoi iterare, facilitando l'individuazione di elementi specifici come immagini o testo.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### Come sostituire le immagini delle forme in un diagramma?
+Itera su ogni `DiagramShape` nella pagina desiderata, verifica se la forma contiene un'immagine e sostituisci i byte dell'immagine con quelli di un nuovo file. `DiagramShape` è il modello per una singola forma in un diagramma, mentre `DiagramWatermarkableImage` memorizza i dati dell'immagine che possono essere applicati a una forma.
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### Come salvare le modifiche e chiudere il Watermarker?
+Quando tutte le modifiche sono complete, chiama `save` sul `Watermarker` per scrivere il diagramma aggiornato su un file, quindi invoca `close` per rilasciare le risorse native. Questo garantisce che i handle dei file vengano liberati e previene perdite di memoria, specialmente durante l'elaborazione di molti diagrammi in un lavoro batch.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+
+public class FeatureSaveAndCloseWatermarker {
+ public static void run(Watermarker watermarker) throws Exception {
+ String outputPath = "YOUR_OUTPUT_DIRECTORY/output.vsdx";
+ watermarker.save(outputPath);
+ watermarker.close();
+ }
+}
+```
+```
+
+## Aggiungere una filigrana allo stesso diagramma (opzionale)
+
+Se hai anche bisogno di marchiare il diagramma, puoi aggiungere una filigrana prima o dopo la sostituzione dell'immagine:
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+
+## Problemi comuni e risoluzione
+
+| Sintomo | Probabile causa | Correzione |
+|---------|----------------|------------|
+| Nessuna modifica dell'immagine dopo l'esecuzione del codice | `DiagramShape.hasImage()` restituito false | Verifica il tipo di forma; alcune forme vettoriali memorizzano le immagini in modo diverso. |
+| OutOfMemoryError su file di grandi dimensioni | Caricamento dell'intero diagramma in una volta | Usa `DiagramLoadOptions.setLoadMode(LoadMode.Stream)` per elaborare le pagine in sequenza. |
+| Filigrana non visibile | Filigrana posizionata dietro il contenuto esistente | Chiama `watermarker.setWatermarkPosition(Position.Foreground)` prima di salvare. |
+
+## Domande frequenti
+
+**Q: Posso sostituire le immagini nei diagrammi protetti da password?**
+A: Sì. Passa la password a `DiagramLoadOptions` quando crei il `Watermarker`.
+
+**Q: La libreria funziona con file .drawio (XML)?**
+A: Assolutamente – GroupDocs.Watermark supporta il formato XML di Draw.io e tratta ogni nodo come una forma.
+
+**Q: Quanti diagrammi posso elaborare in parallelo?**
+A: La libreria è thread‑safe per operazioni di sola lettura; per operazioni di scrittura, limita la concorrenza al numero di core CPU per evitare conflitti di handle dei file.
+
+**Q: Esiste un limite alle dimensioni dell'immagine?**
+A: Sono supportate immagini fino a 100 MB; i file più grandi dovrebbero essere ridimensionati in anticipo per mantenere basso l'uso della memoria.
+
+**Q: Quali opzioni di licenza sono disponibili?**
+A: Puoi iniziare con una prova gratuita di 30 giorni; l'uso in produzione richiede una licenza a pagamento, che può essere ottenuta dallo store di GroupDocs.

+# Proteggi i diagrammi di proprietà intellettuale con GroupDocs.Watermark
+
+La protezione dei diagrammi di proprietà intellettuale è un passaggio critico per qualsiasi organizzazione che condivide risorse di design, flowchart o disegni architettonici. Con GroupDocs.Watermark per Java è possibile caricare programmaticamente file di diagrammi (come `.vsdx`), rilevare istanze di watermark immagine, cercare watermark testuali e rimuoverli in modo sicuro senza corrompere il disegno originale. Questo tutorial ti guida attraverso l’intero processo—dalla configurazione dell’ambiente all’elaborazione batch di grandi librerie di diagrammi—così da poter integrare una protezione IP robusta direttamente nelle tue applicazioni Java.
+
+## Risposte rapide
+- **Quale libreria gestisce i watermark dei diagrammi?** GroupDocs.Watermark for Java.
+- **Posso rilevare watermark immagine così come testo?** Sì, l'API fornisce `ImageDctHashSearchCriteria` per il rilevamento delle immagini e `TextSearchCriteria` per il testo.
+- **È necessaria una licenza commerciale per eseguire il codice?** Una licenza di prova funziona per lo sviluppo; è richiesta una licenza a pagamento per la produzione.
+- **È supportata l'elaborazione batch?** Assolutamente—itera su una cartella e applica la stessa logica di watermark a ciascun file.
+- **Il layout originale del diagramma rimarrà intatto dopo la rimozione?** La libreria elimina solo gli oggetti watermark, preservando tutte le forme, i connettori e la formattazione.
+
+## Cosa sono i diagrammi di proprietà intellettuale?
+I diagrammi di proprietà intellettuale sono rappresentazioni visive—come flowchart, modelli UML, schemi di rete o disegni architettonici—che contengono informazioni proprietarie di proprietà di un individuo o di un’organizzazione. Questi diagrammi spesso trasmettono processi, progetti o strategie confidenziali, rendendoli risorse preziose che richiedono protezione contro copie, distribuzioni o modifiche non autorizzate. Trattandoli come proprietà intellettuale, è possibile applicare misure di tutela legali e tecniche, incluso il watermarking, per mantenere il controllo sul loro utilizzo e diffusione.
+
+## Perché usare GroupDocs.Watermark per Java?
+GroupDocs.Watermark supporta **oltre 50 formati di input e output** (inclusi `.vsdx`, `.vdx`, `.vsx`) e può elaborare diagrammi di centinaia di pagine senza caricare l’intero file in memoria, riducendo il consumo di RAM fino al **70 %** rispetto agli approcci naïve di streaming dei file. L'API offre inoltre un confronto di hash immagine integrato, senza OCR, consentendo operazioni affidabili di `detect image watermark` in meno di **200 ms** per diagramma su un tipico server da 2,5 GHz.
+
+## Prerequisiti
+Prima di iniziare, assicurati di avere:
+
+1. **Java Development Kit (JDK) 8+** – il codice utilizza le API standard di Java 8.
+2. **IDE** – IntelliJ IDEA, Eclipse o qualsiasi editor tu preferisca.
+3. **GroupDocs.Watermark per Java** – sia tramite Maven sia tramite download manuale del JAR.
+
+### Librerie e dipendenze richieste
+Puoi aggiungere la libreria tramite Maven o scaricare direttamente i JAR.
+
+#### Configurazione Maven
+Aggiungi il repository e le dipendenze al tuo file `pom.xml`:
+
+```xml

+
+## Come inizializzare il Watermarker?
+Creare un'istanza di `Watermarker` è il primo passo in qualsiasi flusso di lavoro di watermark. La classe `Watermarker` carica un file di diagramma in memoria e fornisce metodi per cercare, aggiungere e rimuovere watermark. Passando il percorso del diagramma e opzionalmente `DiagramLoadOptions`, ottieni un oggetto che funge da punto centrale per tutte le operazioni successive, garantendo una gestione coerente del documento durante l'intero processo.
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## Come caricare un documento diagramma?
+Caricare un diagramma con `DiagramLoadOptions` ti offre un controllo granulare su come il file viene analizzato. `DiagramLoadOptions` consente di specificare se caricare solo le pagine visibili, se preservare i livelli nascosti e come gestire i font incorporati. Regolare queste opzioni può migliorare notevolmente le prestazioni per diagrammi di grandi dimensioni e garantisce che vengano elaborati solo i componenti necessari del file, riducendo l'uso di memoria e accelerando il rilevamento dei watermark.
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## Come rilevare watermark immagine in un diagramma?
+Il rilevamento dei watermark immagine si basa sulla classe `ImageDctHashSearchCriteria`, che calcola un hash percettivo di un'immagine di riferimento e lo confronta con ogni immagine incorporata nel diagramma. Questo metodo è veloce e tollerante alle piccole variazioni visive, consentendo di individuare loghi o altri watermark grafici anche se sono stati ridimensionati o leggermente modificati. Configurando la soglia di similarità, è possibile bilanciare la sensibilità del rilevamento rispetto a corrispondenze false‑positive.
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## Come cercare watermark testuali?
+La ricerca dei watermark testuali utilizza la classe `TextSearchCriteria`. Questa classe scandisce tutti gli strati testuali all'interno del diagramma, inclusi quelli all'interno di forme, connettori e raggruppamenti, e restituisce le corrispondenze che contengono la stringa o il pattern specificato. La ricerca è insensibile al maiuscolo/minuscolo per impostazione predefinita e può essere affinata con espressioni regolari, consentendo di individuare watermark che potrebbero essere ruotati, parzialmente nascosti o incorporati in strutture di diagrammi complesse.
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## Come rimuovere i watermark da un diagramma?
+La rimozione dei watermark avviene invocando il metodo `clear()` su ogni oggetto `Watermark` restituito da un'operazione di ricerca. Il metodo `clear()` elimina solo gli elementi visuali del watermark lasciando intatti gli oggetti sottostanti del diagramma—come forme, connettori e formattazione. Dopo la pulizia, si salva il documento usando il metodo `save`, producendo una versione pulita del diagramma che mantiene il layout e le funzionalità originali.
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## Applicazioni pratiche
+- **Integrazione software aziendale:** Integra la convalida dei watermark nei sistemi di gestione documentale per applicare automaticamente le politiche IP.
+- **Sistemi di gestione dei contenuti (CMS):** Scansiona i diagrammi caricati dagli utenti alla ricerca di loghi non autorizzati prima della pubblicazione.
+- **Gestione di documenti legali:** Rileva e rimuovi i watermark confidenziali durante la preparazione di pacchetti di prove.
+
+## Problemi comuni e risoluzione
+- **Eccezione licenza mancante:** Assicurati che il file di licenza di prova o a pagamento sia correttamente referenziato tramite `License.setLicense("license_path")`.
+- **Rallentamento con diagrammi grandi:** Abilita `loadOptions.setLoadHiddenLayers(false)` e considera l'elaborazione dei diagrammi in flussi paralleli.
+- **Corrispondenze immagine false‑positive:** Regola la tolleranza dell'hash DCT con `criteria.setSimilarityThreshold(0.85)` per ridurre le corrispondenze accidentali.
+

+**Q: Posso cercare sia watermark testuali che immagine in una singola chiamata?**
+A: Sì, combina i criteri con `OrSearchCriteria` (ad esempio, `new OrSearchCriteria(textCriteria, imageCriteria)`) per recuperare entrambi i tipi contemporaneamente.
+
+**Q: La rimozione dei watermark corromperà il layout del diagramma?**
+A: No. La libreria isola gli oggetti watermark, quindi forme, connettori e formattazione rimangono invariati dopo `clear()`.
+
+**Q: Quali formati di diagramma sono supportati?**
+A: GroupDocs.Watermark gestisce `.vsdx`, `.vdx`, `.vsx` e diversi formati Visio più vecchi, coprendo oltre **30** tipologie di diagrammi.
+
+**Q: Come elaborare migliaia di diagrammi in modo efficiente?**
+A: Usa `ExecutorService` di Java per eseguire il rilevamento/rimozione dei watermark in batch paralleli e riutilizza un unico oggetto di configurazione `Watermarker` per ridurre l'overhead.
+
+**Q: È possibile integrare questo in una pipeline CI/CD?**
+A: Assolutamente. Aggiungi gli snippet Java ai tuoi script di build (Maven/Gradle) ed eseguili come passo di verifica pre‑deployment per garantire che non siano presenti watermark proibiti.

+現代のソフトウェアプロジェクトでは、共有するビジュアル資産、特に図の保護が最重要課題となっています。**How to watermark diagram** pages with text in Java は、ブランドアイデンティティを維持し、無断再利用を防止し、文書の出所を追跡する必要がある企業にとって一般的な要件です。このチュートリアルでは、**GroupDocs.Watermark for Java** を使用して、環境の準備から最終確認までの全プロセスを順を追って解説し、図を自信を持って保護できるようにします。
+
+## クイック回答
+- **どのライブラリが透かしを追加しますか？** GroupDocs.Watermark for Java.
+- **必要なJavaバージョンはどれですか？** JDK 8以上。
+- **テストにライセンスは必要ですか？** 評価用に無料の一時ライセンスが使用できます。
+- **複数ページに一度に透かしを入れられますか？** はい—単一の呼び出しで全ページに透かしを適用します。
+- **このプロセスはメモリ効率が良いですか？** APIはページをストリーミングするため、500ページの図でも200 MB以下のRAMで処理できます。
+
+## Javaで図ページに透かしを入れるとは何ですか？
+これは、Javaライブラリを使用して、Visio、SVG、またはその他のサポートされている形式の図ファイルの各ページに半透明のテキスト（または画像）をプログラムで重ね合わせることを指します。透かしはビジュアルコンテンツの一部となり、任意のビューアで表示されると同時に、元の図データは保持されます。
+
+## なぜ GroupDocs.Watermark for Java を使用するのか？
+GroupDocs.Watermark は **50以上の入力および出力フォーマット** をサポートし、**1 GB** までのファイルをドキュメント全体をメモリに読み込まずに処理し、既存の透かしを検出するための **組み込みOCR** を提供します。これらの定量的な機能により、大規模な図リポジトリに対して高速で信頼性の高い保護が実現でき、APIにより Java アプリケーションへの統合が簡素化されます。
+
+## 前提条件
+- **Java Development Kit (JDK)** 8 以上がマシンにインストールされていること。
+- **IntelliJ IDEA** や **Eclipse** などの IDE が、Javaコードの編集と実行に使用できること。
+- 依存関係管理のための Maven に関する基本的な知識。
+
+### 必要なライブラリと依存関係
+Maven プロジェクトに追加できる GroupDocs.Watermark for Java を使用します。
+
+```xml
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+手動で設定したい場合は、公式リリースページ [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/) からバイナリをダウンロードし、プロジェクトのクラスパスに追加してください。
+
+### ライセンス取得
+まずは無料トライアルとして、[GroupDocs.Trial Licensing](https://purchase.groupdocs.com/temporary-license/) から一時ライセンスを取得してください。本番環境で使用する場合は、フルライセンスを購入し、アプリケーションが読み取れる場所に `license.json` ファイルを配置します。
+
+```java
+// Load the temporary or purchased license – keep unchanged
+```java
+License license = new License();
+license.setLicense("path/to/license/file");
+```
+```
+
+## 実装ガイド
+以下は、図の各ページにテキスト透かしを埋め込む方法をステップバイステップで示す手順です。
+
+### 図ページにテキスト透かしを追加するには？
+図をロードし、`TextWatermark` オブジェクトを作成し、目的のページに適用し、最後に出力を保存します。このエンドツーエンドのフローは、4つの簡潔な API 呼び出しだけで済み、典型的な 10 ページのファイルでは1秒未満で実行され、フォント、色、不透明度、回転のカスタマイズが可能です。
+
+#### 手順 1: 図をロードする
+DiagramLoadOptions は、パスワード処理や特定のフォーマットオプションなど、図ファイルの読み取り方法をライブラリに指示します。まず、`DiagramLoadOptions` を使用して `Watermarker` をインスタンス化します。このオブジェクトはメモリ上のソース図を表します。
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### 手順 2: テキスト透かしを初期化する
+`TextWatermark` は表示テキスト、フォント、色、回転を定義します。透かしを控えめにするために不透明度を設定することもできます。
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### 手順 3: 図ページに透かしを追加する
+DiagramShapeWatermarkOptions は、透かしが図のシェイプにどのように適用されるかを設定します。DiagramWatermarkPlacementType は、透かしが前景に表示されるか背景に表示されるかを指定します。透かしをすべての背景ページ（またはカスタムページ範囲）に適用します。APIは各ページをストリーミングするため、大きなファイルでもメモリ使用量は低く抑えられます。
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### 手順 4: 保存してクローズする
+透かし付きの図を新しいファイルに保存し、リソースを解放します。
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### よくある問題と解決策
+- **File path problems:** 絶対パスを使用するか、作業ディレクトリが図ファイルの場所と一致していることを確認してください。
+- **Version mismatches:** GroupDocs.Watermark のリリースは特定の JDK バージョンに紐付いているため、JDK 8‑17 の互換ビルドを使用していることを確認してください。
+- **Performance bottlenecks:** バッチ処理の場合、単一の `Watermarker` インスタンスを再利用し、バッチ完了後にのみ `close()` を呼び出してください。
+
+## 実用的な応用例
+テキスト透かしは、さまざまな実務シーンで有用です：
+
+1. **Document security** – 競合他社が自社の専有図を再利用するのを防止します。
+2. **Brand reinforcement** – 会社名やスローガンを各ページに直接埋め込みます。
+3. **Collaboration tracking** – ユーザーのイニシャルやタイムスタンプを追加し、誰が図を編集したかを示します。
+
+## パフォーマンス上の考慮点
+- **Memory management:** ライブラリはページを遅延処理するため、常に `watermarker.close()` を呼び出してネイティブリソースを解放してください。
+- **Watermark size:** フォントサイズが大きくなると処理時間が線形に増加します。12pt フォントは可読性と速度のバランスが取れたサイズです。
+- **Batch testing:** 数千ファイルに拡張する前に、代表的なサンプルで透かし処理を実行してテストしてください。
+
+## 結論
+これで、GroupDocs.Watermark を使用して Java で **how to watermark diagram** ページにテキスト透かしを入れるための、完全な本番対応手法が手に入りました。この機能は、ビジュアル資産を保護するだけでなく、共有するすべての図でブランドの一貫性を強化します。
+
+### 次のステップ
+- 追加のビジュアルブランディングとして画像透かしを検討してください。
+- テキストと画像の透かしを組み合わせて多層保護を実現します。
+- 透かし処理フローを CI/CD パイプラインに統合し、図のセキュリティを自動化します。
+
+## よくある質問
+1. **他のファイル形式でも GroupDocs.Watermark を使用できますか？**
+ はい—PDF、DOCX、PPTX、SVG など、50 以上の形式がサポートされています。
+
+2. **透かしを追加できる数に制限はありますか？**
+ 明確な上限はありませんが、ページあたり 10 個以上追加すると描画速度に影響する可能性があります。
+
+3. **図から透かしを削除するには？**
+ `Watermarker.removeWatermarks()` API を使用して既存の透かしを検出し、削除します。
+
+4. **特定のページだけを対象にできますか？**
+ もちろんです—`WatermarkOptions` をページ範囲またはカスタム述語で設定します。
+
+5. **透かしが表示されない場合はどうすればよいですか？**
+ 不透明度、色のコントラスト、回転設定を確認し、トラブルシューティングは API ドキュメントを参照してください。
+
+### 追加の Q&A
+**Q: ライブラリはパスワード保護された図をサポートしていますか？**
+A: はい—ファイルをロードする際に `DiagramLoadOptions` にパスワードを渡します。
+
+**Q: ヘッドレスサーバーで実行できますか？**
+A: API は完全にサーバーサイドで動作し、GUI コンポーネントは不要です。
+
+**Q: 公式にサポートされている Java バージョンはどれですか？**
+A: Java 8 から Java 17 がテストおよびドキュメント化されています。

+# GroupDocs.Watermark を使用した Java での図の画像置換
+
+図ファイル内の画像を手動で更新するのは時間がかかり、ミスが起きやすいです。このチュートリアルでは、数行のコードだけで **Java で図の画像を置換** する方法を学び、必要に応じて **図に透かしを追加** する方法も確認できます。最後まで読むと、Visio、Draw.io、その他サポートされている図形式で動作する任意の Java プロジェクトに組み込める再利用可能なスニペットが手に入ります。
+
+## クイック回答
+- **図の画像置換を処理するライブラリは何ですか？** GroupDocs.Watermark for Java.
+- **基本的な置換に必要なコード行数は？** Watermarker が作成された後はわずか 3 行です。
+- **同時に透かしを追加できますか？** はい – 同じ Watermarker インスタンスに透かしオブジェクトを使用します。
+- **必要な Java バージョンは？** JDK 8 以上。
+- **本番環境でライセンスが必要ですか？** 有効な GroupDocs.Watermark ライセンスが必要です；無料トライアルが利用可能です。
+
+## Java での図の画像置換とは？
+Java で図の画像を置換するとは、.vsdx、.drawio、.svg などの図ファイル内でビットマップ画像を含むシェイプをプログラムで検出し、GroupDocs.Watermark API を使用して埋め込まれた画像を新しい画像に差し替えることを意味します。これにより、図エディタで手動で編集する必要があった更新作業を自動化できます。

+- 有効な GroupDocs.Watermark ライセンス（トライアルまたは永続）。ライセンスは [GroupDocs](https://purchase.groupdocs.com/temporary-license/) から取得できます。
+
+### 必要なライブラリ、バージョン、依存関係
+`pom.xml` に GroupDocs.Watermark リポジトリと依存関係を追加します：
+
+```xml
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+

+```
+```
+
+手動で JAR を管理したい場合は、公式サイトから最新リリースをダウンロードしてください： [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/)。
+
+## Java で図の画像を置換する手順
+
+### 図ファイル用に Watermarker を初期化するには？
+Watermarker はドキュメントを表す主要クラスで、コンテンツ操作用メソッドを提供します。まず、図ファイルをメモリにロードする `Watermarker` オブジェクトを作成します。`Watermarker` クラスは GroupDocs.Watermark のコアエントリーポイントで、読み取り、変更、保存が可能です。`DiagramLoadOptions` を使用して DPI やページ範囲など、フォーマット固有の設定を指定します。`DiagramLoadOptions` は図のロード方法（例：DPI 設定やロードモード）を構成します。
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### 図のコンテンツにアクセスしてシェイプを特定するには？
+ファイルをロードした後、`Watermarker` から `DiagramContent` オブジェクトを取得します。`DiagramContent` は図のページとシェイプの内部階層を表し、ページやシェイプのコレクションを提供するため、画像やテキストなど特定の要素を簡単に検索できます。
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### 図内のシェイプ画像を置換するには？
+目的のページ上の各 `DiagramShape` をループし、シェイプに画像が含まれているか確認して、画像バイト列を新しいファイルのものに置換します。`DiagramShape` は図内の個々のシェイプを表すモデルで、`DiagramWatermarkableImage` がシェイプに適用できる画像データを保持します。
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### 変更を保存して Watermarker を閉じるには？
+すべての変更が完了したら、`Watermarker` の `save` を呼び出して更新された図をファイルに書き込み、`close` でネイティブリソースを解放します。これによりファイルハンドルが解放され、バッチ処理で多数の図を扱う際のメモリリークを防止できます。
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+
+public class FeatureSaveAndCloseWatermarker {
+ public static void run(Watermarker watermarker) throws Exception {
+ String outputPath = "YOUR_OUTPUT_DIRECTORY/output.vsdx";
+ watermarker.save(outputPath);
+ watermarker.close();
+ }
+}
+```
+```
+
+## 同じ図に透かしを追加する（オプション）
+
+図にブランド付けが必要な場合は、画像置換の前後に透かしを追加できます：
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+
+## よくある落とし穴とトラブルシューティング
+
+| 症状 | 考えられる原因 | 対策 |
+|---------|--------------|-----|
+| コード実行後に画像が変わらない | `DiagramShape.hasImage()` が false を返した | シェイプのタイプを確認してください；一部のベクターシェイプは画像を別の方法で保持しています。 |
+| 大きなファイルで OutOfMemoryError が発生 | 図全体を一度にロードしている | `DiagramLoadOptions.setLoadMode(LoadMode.Stream)` を使用してページを順次処理してください。 |
+| 透かしが表示されない | 透かしが既存コンテンツの背後に配置されている | 保存前に `watermarker.setWatermarkPosition(Position.Foreground)` を呼び出してください。 |
+
+## よくある質問
+
+**Q: パスワードで保護された図の画像を置換できますか？**
+A: はい。`Watermarker` 作成時に `DiagramLoadOptions` にパスワードを渡してください。

+# 知的財産図の保護 - GroupDocs.Watermark
+
+知的財産図を保護することは、設計資産、フローチャート、またはアーキテクチャ図を共有するすべての組織にとって重要なステップです。GroupDocs.Watermark for Java を使用すると、図ファイル（例: `.vsdx`）をプログラムで読み込み、画像ウォーターマークのインスタンスを検出し、テキストウォーターマークを検索し、元の図を破損させることなく安全に削除できます。このチュートリアルでは、環境設定から大量の図ライブラリのバッチ処理まで、プロセス全体を順を追って説明しますので、Java アプリケーションに堅牢な IP 保護を直接組み込むことができます。
+
+## クイック回答
+- **どのライブラリが図のウォーターマークを処理しますか？** GroupDocs.Watermark for Java.
+- **画像ウォーターマークとテキストの両方を検出できますか？** Yes, the API provides `ImageDctHashSearchCriteria` for image detection and `TextSearchCriteria` for text.
+- **コードを実行するのに商用ライセンスが必要ですか？** A trial license works for development; a paid license is required for production.
+- **バッチ処理はサポートされていますか？** Absolutely—loop over a folder and apply the same watermark logic to each file.
+- **削除後も元の図のレイアウトはそのままですか？** The library clears only watermark objects, preserving all shapes, connectors, and formatting.
+
+## 知的財産図とは何ですか？
+知的財産図は、フローチャート、UML モデル、ネットワーク図、または建築図面など、個人または組織が所有する専有情報を含む視覚的表現です。これらの図は機密プロセス、設計、戦略を伝えることが多く、無断コピー、配布、改変から保護すべき価値ある資産です。知的財産として扱うことで、ウォーターマークを含む法的・技術的な保護策を適用し、使用と配布を管理できます。
+
+## なぜ GroupDocs.Watermark for Java を使用するのか？
+GroupDocs.Watermark は **50+** の入力および出力フォーマット（`.vsdx`、`.vdx`、`.vsx` など）をサポートし、ファイル全体をメモリに読み込むことなく数百ページに及ぶ図を処理できるため、ナイーブなファイルストリーム方式と比較して RAM 使用量を最大 **70 %** 削減します。API には OCR 不要の画像ハッシュ比較が組み込まれており、典型的な 2.5 GHz サーバー上で 1 図あたり **200 ms** 未満で信頼性の高い画像ウォーターマーク検出が可能です。
+
+## 前提条件
+開始する前に、以下を用意してください。
+
+1. **Java Development Kit (JDK) 8+** – コードは標準の Java 8 API を使用します。
+2. **IDE** – IntelliJ IDEA、Eclipse、またはお好みのエディタ。
+3. **GroupDocs.Watermark for Java** – Maven 経由または手動 JAR ダウンロードで入手。
+
+### 必要なライブラリと依存関係
+ライブラリは Maven で追加するか、JAR を直接ダウンロードできます。
+
+#### Maven 設定
+`pom.xml` ファイルにリポジトリと依存関係のエントリを追加します:
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+
+#### 直接ダウンロード
+手動インストールを希望する場合は、[GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/) から最新リリースをダウンロードしてください。
+
+### ライセンス取得
+- **無料トライアル:** API 機能の評価に最適です。
+- **一時ライセンス:** 機能制限なしで短期テストに使用できます。
+- **購入:** 本番環境での展開とプレミアムフォーマットのロック解除に必要です。
+
+## Watermarker の初期化方法は？
+`Watermarker` インスタンスの作成は、すべてのウォーターマークワークフローの最初のステップです。`Watermarker` クラスは図ファイルをメモリに読み込み、検索、追加、削除のメソッドを提供します。図のパスとオプションの `DiagramLoadOptions` を渡すことで、以降のすべての操作の中心となるオブジェクトを取得し、ドキュメント全体の一貫した取り扱いを保証します。
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## 図ドキュメントの読み込み方法は？
+`DiagramLoadOptions` を使用して図を読み込むと、ファイルの解析方法を細かく制御できます。`DiagramLoadOptions` では、表示ページのみを読み込むか、非表示レイヤーを保持するか、埋め込みフォントの取り扱いなどを指定できます。これらのオプションを調整することで、大規模な図のパフォーマンスが大幅に向上し、必要な部分だけを処理してメモリ使用量とウォーターマーク検出の速度を最適化できます。
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## 図内の画像ウォーターマークを検出する方法は？
+画像ウォーターマークの検出は `ImageDctHashSearchCriteria` クラスに依存します。このクラスは参照画像の知覚ハッシュを計算し、図内のすべての埋め込み画像と比較します。軽微な視覚的変化に耐える高速な手法で、サイズ変更や微調整が行われたロゴやグラフィックウォーターマークも検出できます。類似度閾値を設定することで、検出感度と偽陽性のバランスを調整できます。
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## テキストウォーターマークを検索する方法は？
+テキストウォーターマークの検索には `TextSearchCriteria` クラスを使用します。このクラスは図内のすべてのテキスト層（シェイプ、コネクタ、グループ化された要素内も含む）を走査し、指定した文字列またはパターンを含む一致を返します。デフォルトで大文字小文字を区別せず、正規表現で絞り込むこともできるため、回転、部分的に隠された、または複雑な構造に埋め込まれたウォーターマークも検出可能です。
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## 図からウォーターマークを削除する方法は？
+削除は検索操作で取得した各 `Watermark` オブジェクトの `clear()` メソッドを呼び出すことで実行します。`clear()` は視覚的なウォーターマーク要素のみを削除し、形状、コネクタ、書式設定などの基礎となる図オブジェクトはそのまま残します。削除後は `save` メソッドでドキュメントを保存し、元のレイアウトと機能を保持したクリーンな図バージョンを生成します。
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## 実用的な応用例
+- **エンタープライズソフトウェア統合:** ドキュメント管理システムにウォーターマーク検証を組み込み、IP ポリシーを自動的に適用。
+- **コンテンツ管理システム (CMS):** ユーザーがアップロードした図をスキャンし、無許可ロゴが含まれていないか公開前にチェック。
+- **法務文書取り扱い:** 証拠バンドル作成時に機密ウォーターマークを検出・除去。
+
+## よくある落とし穴とトラブルシューティング
+- **Missing license exception:** `License.setLicense("license_path")` でトライアルまたは有料ライセンスファイルが正しく参照されていることを確認してください。
+- **Large diagram slowdown:** `loadOptions.setLoadHiddenLayers(false)` を有効にし、図の並列ストリーム処理を検討してください。
+- **False‑positive image matches:** `criteria.setSimilarityThreshold(0.85)` で DCT ハッシュの許容度を調整し、誤検出を減らします。
+
+## よくある質問
+
+**Q: テキストと画像の両方のウォーターマークを単一の呼び出しで検索できますか？**
+A: はい、`OrSearchCriteria` を組み合わせて（例: `new OrSearchCriteria(textCriteria, imageCriteria)`）両方のタイプを同時に取得できます。
+
+**Q: ウォーターマークを削除すると図のレイアウトが壊れますか？**
+A: いいえ。ライブラリはウォーターマークオブジェクトだけを分離するため、`clear()` 後も形状、コネクタ、書式設定は変更されません。
+
+**Q: サポートされている図のフォーマットは何ですか？**
+A: GroupDocs.Watermark は `.vsdx`, `.vdx`, `.vsx` などの古い Visio フォーマットを含め、**30** 以上の図タイプをサポートします。
+
+**Q: 何千もの図を効率的に処理するにはどうすればよいですか？**
+A: Java の `ExecutorService` を使用してウォーターマークの検出/削除を並列バッチで実行し、`Watermarker` 設定オブジェクトを再利用してオーバーヘッドを削減します。
+
+**Q: これを CI/CD パイプラインに統合できますか？**
+A: もちろんです。Java スニペットをビルドスクリプト（Maven/Gradle）に追加し、デプロイ前の検証ステップとして実行すれば、禁止されたウォーターマークが存在しないことを確認できます。

+
+# Java에서 텍스트로 다이어그램 페이지에 워터마크 추가하는 방법
+
+현대 소프트웨어 프로젝트에서는 공유하는 시각 자산, 특히 다이어그램을 보호하는 것이 최우선 과제가 되었습니다. **다이어그램에 워터마크 추가 방법**은 브랜드 아이덴티티를 유지하고, 무단 재사용을 방지하며, 문서 출처를 추적해야 하는 기업에게 흔히 요구되는 사항입니다. 이 튜토리얼은 **GroupDocs.Watermark for Java**를 사용하여 환경 준비부터 최종 검증까지 전체 과정을 단계별로 안내하므로 다이어그램을 자신 있게 보호할 수 있습니다.
+
+## 빠른 답변
+- **워터마크를 추가하는 라이브러리는 무엇인가요?** GroupDocs.Watermark for Java.
+- **필요한 Java 버전은?** JDK 8 또는 그 이상.
+- **테스트에 라이선스가 필요합니까?** 평가용으로 무료 임시 라이선스를 사용할 수 있습니다.
+- **한 번에 여러 페이지에 워터마크를 적용할 수 있나요?** 예—단일 호출로 모든 페이지에 워터마크를 적용합니다.
+- **이 프로세스는 메모리 효율적인가요?** API가 페이지를 스트리밍하므로 500페이지 다이어그램도 200 MB RAM 이하로 유지됩니다.
+
+## Java에서 다이어그램 페이지에 워터마크를 적용한다는 것은 무엇인가요?
+이는 Java 라이브러리를 사용하여 Visio, SVG 등 지원되는 형식의 다이어그램 파일 각 페이지에 반투명 텍스트(또는 이미지)를 프로그래밍 방식으로 오버레이하는 것을 의미합니다. 워터마크는 시각 콘텐츠의 일부가 되어 모든 뷰어에서 보이면서 원본 다이어그램 데이터를 보존합니다.
+
+## 왜 GroupDocs.Watermark for Java를 사용하나요?
+GroupDocs.Watermark는 **50+ 입력 및 출력 형식**을 지원하고, 전체 문서를 메모리에 로드하지 않고 **1 GB**까지의 파일을 처리하며, 기존 워터마크를 감지하기 위한 **내장 OCR**을 제공합니다. 이러한 정량화된 기능은 대규모 다이어그램 저장소에 대한 빠르고 신뢰할 수 있는 보호를 보장하고, API는 Java 애플리케이션에의 통합을 간소화합니다.
+
+## 전제 조건
+- **Java Development Kit (JDK)** 8 이상이 머신에 설치되어 있어야 합니다.
+- 편집 및 Java 코드를 실행하기 위한 **IntelliJ IDEA** 또는 **Eclipse**와 같은 IDE.
+- 의존성 관리를 위한 Maven에 대한 기본적인 이해.
+
+### 필요한 라이브러리 및 종속성
+우리는 Maven 프로젝트에 추가할 수 있는 GroupDocs.Watermark for Java를 사용할 것입니다:
+
+```xml
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+수동 설정을 선호한다면 공식 릴리스 페이지 [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/)에서 바이너리를 다운로드하고 프로젝트의 클래스패스에 추가하십시오.
+
+### 라이선스 획득
+무료 체험을 시작하려면 [GroupDocs.Trial Licensing](https://purchase.groupdocs.com/temporary-license/)에서 임시 라이선스를 얻으십시오. 실제 운영에서는 정식 라이선스를 구매하고 애플리케이션이 읽을 수 있는 위치에 `license.json` 파일을 배치합니다:
+
+```java
+// Load the temporary or purchased license – keep unchanged
+```java
+License license = new License();
+license.setLicense("path/to/license/file");
+```
+```
+
+## 구현 가이드
+아래는 다이어그램의 모든 페이지에 텍스트 워터마크를 삽입하는 방법을 단계별로 보여주는 안내입니다.
+
+### 다이어그램 페이지에 텍스트 워터마크를 추가하려면 어떻게 하나요?
+다이어그램을 로드하고 `TextWatermark` 객체를 생성한 뒤 원하는 페이지에 적용하고 최종적으로 출력 파일을 저장합니다. 이 엔드‑투‑엔드 흐름은 네 번의 간결한 API 호출만 필요하며 일반적인 10페이지 파일의 경우 1초 미만에 실행되며, 글꼴, 색상, 불투명도 및 회전 등을 사용자 정의할 수 있습니다.
+
+#### Step 1: 다이어그램 로드
+DiagramLoadOptions는 라이브러리에게 비밀번호 처리나 특정 형식 옵션 등 다이어그램 파일을 읽는 방법을 알려줍니다. 먼저 `DiagramLoadOptions`와 함께 `Watermarker`를 인스턴스화합니다. 이 객체는 메모리 내에서 원본 다이어그램을 나타냅니다.
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### Step 2: 텍스트 워터마크 초기화
+`TextWatermark`는 표시될 텍스트, 글꼴, 색상 및 회전을 정의합니다. 불투명도를 설정하여 워터마크를 은은하게 만들 수도 있습니다.
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### Step 3: 다이어그램 페이지에 워터마크 추가
+DiagramShapeWatermarkOptions는 워터마크가 다이어그램 도형에 적용되는 방식을 구성합니다. DiagramWatermarkPlacementType은 워터마크가 전경에 나타날지 배경에 나타날지를 지정합니다. 워터마크를 모든 배경 페이지(또는 사용자 지정 페이지 범위)에 적용합니다. API는 각 페이지를 스트리밍하므로 대용량 파일에서도 메모리 사용량이 낮게 유지됩니다.
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### Step 4: 저장 및 닫기
+워터마크가 적용된 다이어그램을 새 파일에 저장하고 리소스를 해제합니다.
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### 일반적인 문제 및 해결책
+- **파일 경로 문제:** 절대 경로를 사용하거나 작업 디렉터리가 다이어그램 파일 위치와 일치하는지 확인하십시오.
+- **버전 불일치:** GroupDocs.Watermark 릴리스는 특정 JDK 버전과 연결되어 있으므로 호환 가능한 JDK 8‑17 빌드를 사용하고 있는지 확인하십시오.
+- **성능 병목 현상:** 배치 처리의 경우 단일 `Watermarker` 인스턴스를 재사용하고 배치가 완료된 후에만 `close()`를 호출하십시오.
+
+## 실제 적용 사례
+텍스트 워터마크는 다양한 실제 시나리오에서 유용합니다:
+
+1. **Document security** – 경쟁자가 독점 다이어그램을 재사용하는 것을 방지합니다.
+2. **Brand reinforcement** – 회사 이름이나 슬로건을 모든 페이지에 직접 삽입합니다.
+3. **Collaboration tracking** – 사용자의 이니셜이나 타임스탬프를 추가하여 누가 다이어그램을 편집했는지 표시합니다.
+
+## 성능 고려 사항
+- **Memory management:** 라이브러리는 페이지를 지연 처리하므로 항상 `watermarker.close()`를 호출하여 네이티브 리소스를 해제하십시오.
+- **Watermark size:** 큰 글꼴 크기는 처리 시간을 선형적으로 증가시키며, 12pt 글꼴이 가독성과 속도 사이의 좋은 균형을 제공합니다.
+- **Batch testing:** 수천 개 파일로 확장하기 전에 대표 샘플에 워터마크 루틴을 실행하십시오.
+
+## 결론
+이제 GroupDocs.Watermark를 사용하여 Java에서 텍스트로 **다이어그램에 워터마크 추가 방법**에 대한 완전하고 프로덕션 준비된 방법을 갖추었습니다. 이 기능은 시각 자산을 보호할 뿐만 아니라 모든 공유 다이어그램에 걸쳐 브랜드 일관성을 강화합니다.
+
+### 다음 단계
+- 추가적인 시각 브랜딩을 위해 이미지 워터마크를 탐색하십시오.
+- 텍스트와 이미지 워터마크를 결합하여 다중 레이어 보호를 구현하십시오.
+- 워터마크 흐름을 CI/CD 파이프라인에 통합하여 다이어그램 보안을 자동화하십시오.
+
+## 자주 묻는 질문
+1. **다른 파일 형식에도 GroupDocs.Watermark를 사용할 수 있나요?**
+ 예—PDF, DOCX, PPTX, SVG 등을 포함한 50개 이상의 형식을 지원합니다.
+
+2. **추가할 수 있는 워터마크 수에 제한이 있나요?**
+ 엄격한 제한은 없지만 페이지당 10개 이상 추가하면 렌더링 속도에 영향을 줄 수 있습니다.
+
+3. **다이어그램에서 워터마크를 제거하려면 어떻게 해야 하나요?**
+ `Watermarker.removeWatermarks()` API를 사용하여 기존 워터마크를 감지하고 삭제합니다.
+
+4. **특정 페이지만 대상으로 할 수 있나요?**
+ 물론입니다—`WatermarkOptions`를 페이지 범위나 사용자 정의 프레디케이트로 구성하십시오.
+
+5. **워터마크가 보이지 않을 경우 어떻게 해야 하나요?**
+ 불투명도, 색상 대비, 회전 설정을 확인하고, 문제 해결을 위해 API 문서를 참고하십시오.
+
+### 추가 Q&A
+**Q: 라이브러리가 비밀번호로 보호된 다이어그램을 지원하나요?**
+A: 예—파일을 로드할 때 `DiagramLoadOptions`에 비밀번호를 전달하면 됩니다.
+
+**Q: 이를 헤드리스 서버에서 실행할 수 있나요?**
+A: API는 완전히 서버 측이며 GUI 구성 요소가 필요하지 않습니다.
+
+**Q: 공식적으로 지원되는 Java 버전은 무엇인가요?**
+A: Java 8부터 Java 17까지 테스트 및 문서화되었습니다.
+
+**Q: GroupDocs.Watermark는 대용량 파일을 어떻게 처리하나요?**
+A: 페이지를 스트리밍하여 1 GB 다이어그램에서도 피크 메모리 사용량을 200 MB 이하로 유지합니다.
+
+**Q: 저장하기 전에 워터마크를 미리 볼 수 있는 방법이 있나요?**
+A: `Watermarker.getResultImage()`를 사용하여任意 페이지의 미리보기 비트맵을 생성합니다.

+# Java에서 GroupDocs.Watermark를 사용하여 다이어그램 이미지 교체
+
+다이어그램 파일 내부의 이미지를 수동으로 업데이트하는 것은 시간도 많이 걸리고 오류가 발생하기 쉽습니다. 이 튜토리얼에서는 **Java에서 다이어그램 이미지 교체**를 몇 줄의 코드만으로 수행하는 방법을 배우고, 필요할 때 **다이어그램에 워터마크 추가** 방법도 확인할 수 있습니다. 최종적으로 Visio, Draw.io 또는 기타 지원되는 다이어그램 형식과 함께 작업하는 모든 Java 프로젝트에 삽입할 수 있는 재사용 가능한 스니펫을 얻게 됩니다.
+
+## 빠른 답변
+- **다이어그램 이미지 교체를 처리하는 라이브러리는?** GroupDocs.Watermark for Java.
+- **기본 교체에 필요한 코드 라인은 몇 줄인가요?** Watermarker를 생성한 후 단 세 줄만 필요합니다.
+- **동시에 워터마크를 추가할 수 있나요?** 예 – 동일한 Watermarker 인스턴스에 워터마크 객체를 사용합니다.
+- **필요한 Java 버전은?** JDK 8 이상.
+- **프로덕션 사용에 라이선스가 필요합니까?** 유효한 GroupDocs.Watermark 라이선스가 필요합니다; 무료 체험판을 사용할 수 있습니다.
+
+## Java에서 다이어그램 이미지 교체란?
+Java에서 다이어그램 이미지 교체란 다이어그램 파일(.vsdx, .drawio 또는 .svg 등) 내부에 비트맵 그래픽을 포함하는 도형을 프로그래밍 방식으로 찾아, GroupDocs.Watermark API를 사용하여 해당 삽입된 이미지를 새로운 이미지로 교체하는 것을 의미합니다. 이를 통해 다이어그램 편집기에서 수동으로 편집해야 하는 업데이트 작업을 자동화할 수 있습니다.
+
+## 다이어그램 이미지 교체에 GroupDocs.Watermark를 사용하는 이유
+GroupDocs.Watermark는 **50개 이상의 입력 및 출력 형식**을 지원합니다 – Visio, Draw.io, SVG 등을 포함 – 그리고 전체 문서를 메모리에 로드하지 않고 **최대 500 MB 파일**을 처리할 수 있어, 단순 파일 스트림 방식에 비해 **CPU 사용량을 30 % 감소**시킵니다.
+
+## 사전 요구 사항
+- JDK 8 이상이 설치되어 있어야 합니다.
+- Java 개발을 위한 IDE(IntelliJ IDEA, Eclipse 또는 VS Code).
+- Maven(또는 JAR를 수동으로 추가할 수 있는 방법).
+- 유효한 GroupDocs.Watermark 라이선스(체험판 또는 정식). 라이선스는 [GroupDocs](https://purchase.groupdocs.com/temporary-license/)에서 얻을 수 있습니다.

+
+## Java에서 다이어그램 이미지 교체 단계별 가이드
+
+### 다이어그램 파일에 대한 Watermarker를 초기화하는 방법은?
+Watermarker는 문서를 나타내며 콘텐츠 조작 메서드를 제공하는 주요 클래스입니다. 시작하려면 다이어그램 파일을 메모리로 로드하는 `Watermarker` 객체를 생성합니다. `Watermarker` 클래스는 GroupDocs.Watermark의 핵심 진입점으로, 문서를 읽고, 수정하고, 저장할 수 있게 해줍니다. `DiagramLoadOptions`를 사용하여 DPI나 페이지 범위와 같은 형식별 설정을 지정합니다. `DiagramLoadOptions`는 다이어그램 로드 방식을 구성하며, 예를 들어 DPI나 로드 모드를 설정할 수 있습니다.
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### 다이어그램 콘텐츠에 접근하여 도형을 찾는 방법은?
+파일을 로드한 후 `Watermarker`에서 `DiagramContent` 객체를 가져옵니다. `DiagramContent`는 다이어그램의 페이지와 도형의 내부 계층 구조를 나타냅니다. 이 모델은 페이지와 도형 컬렉션을 제공하므로 반복하면서 이미지나 텍스트와 같은 특정 요소를 쉽게 찾을 수 있습니다.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### 다이어그램에서 도형 이미지를 교체하는 방법은?
+원하는 페이지의 각 `DiagramShape`을 순회하면서 도형에 이미지가 포함되어 있는지 확인하고, 이미지 바이트를 새 파일의 바이트로 교체합니다. `DiagramShape`는 다이어그램 내 개별 도형을 나타내는 모델이며, `DiagramWatermarkableImage`는 도형에 적용할 수 있는 이미지 데이터를 저장합니다.
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### 변경 사항을 저장하고 Watermarker를 닫는 방법은?
+모든 수정이 완료되면 `Watermarker`의 `save` 메서드를 호출하여 업데이트된 다이어그램을 파일에 기록하고, `close`를 호출하여 네이티브 리소스를 해제합니다. 이렇게 하면 파일 핸들이 해제되어 메모리 누수를 방지할 수 있으며, 특히 배치 작업으로 많은 다이어그램을 처리할 때 유용합니다.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+
+public class FeatureSaveAndCloseWatermarker {
+ public static void run(Watermarker watermarker) throws Exception {
+ String outputPath = "YOUR_OUTPUT_DIRECTORY/output.vsdx";
+ watermarker.save(outputPath);
+ watermarker.close();
+ }
+}
+```
+```
+
+## 동일한 다이어그램에 워터마크 추가 (옵션)
+
+다이어그램에 브랜드를 추가해야 하는 경우, 이미지 교체 전후에 워터마크를 추가할 수 있습니다:
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+
+## 일반적인 함정 및 문제 해결
+
+| 증상 | 가능한 원인 | 해결 방법 |
+|---------|--------------|-----|
+| 코드 실행 후 이미지가 변경되지 않음 | `DiagramShape.hasImage()`가 false를 반환함 | 도형 유형을 확인하십시오; 일부 벡터 도형은 이미지를 다르게 저장합니다. |
+| 큰 파일에서 OutOfMemoryError 발생 | 다이어그램을 한 번에 전체 로드 | `DiagramLoadOptions.setLoadMode(LoadMode.Stream)`을 사용하여 페이지를 순차적으로 처리하십시오. |
+| 워터마크가 보이지 않음 | 워터마크가 기존 콘텐츠 뒤에 배치됨 | 저장하기 전에 `watermarker.setWatermarkPosition(Position.Foreground)`를 호출하십시오. |
+
+## 자주 묻는 질문
+
+**Q: 암호로 보호된 다이어그램의 이미지를 교체할 수 있나요?**
+A: 예. `Watermarker`를 생성할 때 `DiagramLoadOptions`에 비밀번호를 전달하면 됩니다.
+
+**Q: 라이브러리가 .drawio(XML) 파일에서도 작동하나요?**
+A: 물론입니다 – GroupDocs.Watermark는 Draw.io XML 형식을 지원하며 각 노드를 도형으로 처리합니다.
+
+**Q: 동시에 몇 개의 다이어그램을 처리할 수 있나요?**
+A: 라이브러리는 읽기 전용 작업에 대해 스레드 안전합니다; 쓰기 작업의 경우 파일 핸들 충돌을 방지하기 위해 동시성을 CPU 코어 수로 제한하십시오.
+
+**Q: 이미지 크기에 제한이 있나요?**
+A: 최대 100 MB까지 지원됩니다; 더 큰 파일은 메모리 사용량을 낮추기 위해 사전에 크기를 조정해야 합니다.
+
+**Q: 어떤 라이선스 옵션이 제공되나요?**
+A: 무료 30일 체험판으로 시작할 수 있으며, 프로덕션 사용에는 유료 라이선스가 필요합니다. 라이선스는 GroupDocs 스토어에서 구매할 수 있습니다.

+# GroupDocs.Watermark로 지적 재산 다이어그램 보호
+
+지적 재산 다이어그램을 보호하는 것은 디자인 자산, 흐름도 또는 건축 도면을 공유하는 모든 조직에 필수적인 단계입니다. Java용 GroupDocs.Watermark를 사용하면 다이어그램 파일(예: `.vsdx`)을 프로그래밍 방식으로 로드하고, 이미지 워터마크 인스턴스를 감지하며, 텍스트 워터마크를 검색하고, 원본 도면을 손상시키지 않고 안전하게 제거할 수 있습니다. 이 튜토리얼은 환경 설정부터 대규모 다이어그램 라이브러리의 배치 처리까지 전체 과정을 단계별로 안내하므로, Java 애플리케이션에 강력한 IP 보호 기능을 직접 삽입할 수 있습니다.
+
+## 빠른 답변
+- **어떤 라이브러리가 다이어그램 워터마크를 처리합니까?** GroupDocs.Watermark for Java.
+- **이미지 워터마크와 텍스트 워터마크를 모두 감지할 수 있나요?** 예, API는 이미지 감지를 위해 `ImageDctHashSearchCriteria`를, 텍스트를 위해 `TextSearchCriteria`를 제공합니다.
+- **코드를 실행하려면 상용 라이선스가 필요합니까?** 개발에는 체험 라이선스로 충분하고, 운영 환경에서는 유료 라이선스가 필요합니다.
+- **배치 처리가 지원됩니까?** 물론입니다—폴더를 순회하면서 각 파일에 동일한 워터마크 로직을 적용합니다.
+- **제거 후 원본 다이어그램 레이아웃이 그대로 유지됩니까?** 라이브러리는 워터마크 객체만 삭제하고 모든 도형, 연결선 및 서식을 보존합니다.
+
+## 지적 재산 다이어그램이란 무엇인가요?
+지적 재산 다이어그램은 흐름도, UML 모델, 네트워크 설계도 또는 건축 도면과 같이 개인이나 조직이 소유한 독점 정보를 포함하는 시각적 표현입니다. 이러한 다이어그램은 종종 기밀 프로세스, 설계 또는 전략을 전달하므로, 무단 복제, 배포 또는 변조로부터 보호해야 하는 가치 있는 자산입니다. 이를 지적 재산으로 취급하면 워터마크와 같은 기술적·법적 보호 수단을 적용하여 사용 및 배포를 통제할 수 있습니다.
+
+## Java용 GroupDocs.Watermark를 사용하는 이유는?
+GroupDocs.Watermark는 **50개 이상의 입력 및 출력 포맷**(예: `.vsdx`, `.vdx`, `.vsx`)을 지원하며, 전체 파일을 메모리에 로드하지 않고도 수백 페이지에 달하는 다이어그램을 처리할 수 있어, 일반적인 파일 스트림 방식에 비해 RAM 사용량을 **70 %**까지 절감합니다. 또한 API는 OCR 없이 이미지 해시 비교를 내장하고 있어, 일반적인 2.5 GHz 서버에서 다이어그램당 **200 ms** 이내에 `detect image watermark` 작업을 신뢰성 있게 수행합니다.
+
+## 전제 조건
+시작하기 전에 다음을 확인하십시오:
+
+1. **Java Development Kit (JDK) 8+** – 코드는 표준 Java 8 API를 사용합니다.
+2. **IDE** – IntelliJ IDEA, Eclipse 또는 선호하는 편집기.
+3. **GroupDocs.Watermark for Java** – Maven을 통해서든 수동 JAR 다운로드를 통해서든 사용 가능합니다.
+
+### 필요한 라이브러리 및 종속성
+라이브러리를 Maven을 통해 추가하거나 JAR 파일을 직접 다운로드할 수 있습니다.
+
+#### Maven 설정
+`pom.xml` 파일에 저장소와 종속성 항목을 추가하십시오:

+`Watermarker` 인스턴스를 생성하는 것이 모든 워터마크 워크플로우의 첫 단계입니다. `Watermarker` 클래스는 다이어그램 파일을 메모리로 로드하고, 워터마크 검색·추가·제거 메서드를 제공합니다. 다이어그램 경로와 선택적 `DiagramLoadOptions`를 전달하면, 이후 모든 작업의 중심이 되는 객체를 얻어 문서를 일관되게 처리할 수 있습니다.
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## 다이어그램 문서를 로드하는 방법은?
+`DiagramLoadOptions`와 함께 다이어그램을 로드하면 파일 파싱 방식을 세밀하게 제어할 수 있습니다. `DiagramLoadOptions`를 사용하면 보이는 페이지만 로드할지, 숨겨진 레이어를 보존할지, 포함된 글꼴을 어떻게 처리할지 지정할 수 있습니다. 이러한 옵션을 조정하면 대형 다이어그램의 성능을 크게 향상시키고, 필요한 부분만 처리하여 메모리 사용량을 줄이고 워터마크 감지 속도를 높일 수 있습니다.
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## 다이어그램에서 이미지 워터마크를 감지하는 방법은?
+이미지 워터마크 감지는 `ImageDctHashSearchCriteria` 클래스를 사용합니다. 이 클래스는 기준 이미지의 퍼셉추얼 해시를 계산하고 다이어그램에 포함된 모든 이미지와 비교합니다. 이 방법은 빠르고 작은 시각적 변형에도 강인하여, 로고나 기타 그래픽 워터마크가 크기가 조정되거나 약간 변형된 경우에도 찾아낼 수 있습니다. 유사도 임계값을 설정하면 감지 민감도와 오탐률 사이의 균형을 맞출 수 있습니다.
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## 텍스트 워터마크를 검색하는 방법은?
+텍스트 워터마크 검색은 `TextSearchCriteria` 클래스를 사용합니다. 이 클래스는 도형, 연결선, 그룹 내 텍스트 레이어를 모두 스캔하고 지정된 문자열이나 패턴을 포함하는 일치 항목을 반환합니다. 기본적으로 대소문자를 구분하지 않으며, 정규식을 활용해 회전되었거나 부분적으로 가려진 텍스트, 복잡한 구조 내에 숨겨진 워터마크도 찾아낼 수 있습니다.
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## 다이어그램에서 워터마크를 제거하는 방법은?
+워터마크 제거는 검색 작업으로 반환된 각 `Watermark` 객체에 대해 `clear()` 메서드를 호출함으로써 수행됩니다. `clear()` 메서드는 시각적 워터마크 요소만 삭제하고, 도형, 연결선 및 서식과 같은 기본 다이어그램 객체는 그대로 유지합니다. 제거 후에는 `save` 메서드로 문서를 저장하여 원본 레이아웃과 기능을 그대로 유지하는 깨끗한 다이어그램 버전을 만들 수 있습니다.
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## 실제 적용 사례
+- **엔터프라이즈 소프트웨어 통합:** 문서 관리 시스템에 워터마크 검증을 삽입해 IP 정책을 자동으로 적용합니다.
+- **콘텐츠 관리 시스템(CMS):** 사용자가 업로드한 다이어그램을 스캔해 무단 로고가 포함되어 있는지 확인하고, 게시 전에 차단합니다.
+- **법률 문서 처리:** 증거 번들을 준비할 때 기밀 워터마크를 감지하고 제거합니다.
+
+## 일반적인 함정 및 문제 해결
+- **라이선스 누락 예외:** `License.setLicense("license_path")`를 통해 체험 또는 유료 라이선스 파일이 올바르게 참조되는지 확인하십시오.
+- **대형 다이어그램 속도 저하:** `loadOptions.setLoadHiddenLayers(false)`를 활성화하고, 다이어그램을 병렬 스트림으로 처리하는 것을 고려하십시오.
+- **오탐 이미지 매치:** `criteria.setSimilarityThreshold(0.85)`로 DCT 해시 허용 오차를 조정하여 우발적인 매치를 감소시킵니다.
+
+## 자주 묻는 질문
+
+**Q: 텍스트와 이미지 워터마크를 한 번에 검색할 수 있나요?**
+A: 예, `OrSearchCriteria`(예: `new OrSearchCriteria(textCriteria, imageCriteria)`)를 사용해 두 유형을 동시에 검색할 수 있습니다.
+
+**Q: 워터마크를 제거하면 다이어그램 레이아웃이 손상되나요?**
+A: 아니요. 라이브러리는 워터마크 객체만 격리하므로 `clear()` 후에도 도형, 연결선 및 서식이 그대로 유지됩니다.
+
+**Q: 지원되는 다이어그램 포맷은 무엇인가요?**
+A: GroupDocs.Watermark는 `.vsdx`, `.vdx`, `.vsx` 및 여러 오래된 Visio 포맷을 처리하며, **30개** 이상의 다이어그램 유형을 지원합니다.
+
+**Q: 수천 개의 다이어그램을 효율적으로 처리하려면 어떻게 해야 하나요?**
+A: Java의 `ExecutorService`를 활용해 워터마크 감지·제거 작업을 병렬 배치로 실행하고, `Watermarker` 구성 객체를 재사용해 오버헤드를 최소화하십시오.
+
+**Q: CI/CD 파이프라인에 통합할 수 있나요?**
+A: 물론입니다. Java 스니펫을 빌드 스크립트(Maven/Gradle)에 추가하고, 배포 전 검증 단계에서 실행해 금지된 워터마크가 존재하지 않는지 확인하십시오.

+# Jak dodać znak wodny do stron diagramu tekstem w Javie
+
+W nowoczesnych projektach programistycznych ochrona udostępnianych zasobów wizualnych — szczególnie diagramów — stała się priorytetem. **Jak dodać znak wodny do stron diagramu** tekstem w Javie to powszechne wymaganie firm, które muszą zachować tożsamość marki, zapobiegać nieautoryzowanemu ponownemu użyciu i śledzić pochodzenie dokumentów. Ten samouczek przeprowadzi Cię przez cały proces przy użyciu **GroupDocs.Watermark for Java**, od przygotowania środowiska po ostateczną weryfikację, abyś mógł pewnie zabezpieczyć swoje diagramy.
+
+## Szybkie odpowiedzi
+- **Jaka biblioteka dodaje znaki wodne?** GroupDocs.Watermark for Java.
+- **Jaką wersję Javy wymaga?** JDK 8 lub nowsza.
+- **Czy potrzebna jest licencja do testów?** Tymczasowa darmowa licencja działa w trybie ewaluacji.
+- **Czy mogę znakować wiele stron jednocześnie?** Tak — zastosuj znak wodny do wszystkich stron w jednym wywołaniu.
+- **Czy proces jest efektywny pod względem pamięci?** API strumieniuje strony, więc nawet diagramy o 500 stronach mieszczą się w pamięci poniżej 200 MB RAM.
+
+## Czym jest znakowanie wodą stron diagramu w Javie?
+Polega na programowym nakładaniu półprzezroczystego tekstu (lub obrazów) na każdą stronę pliku diagramu — takiego jak Visio, SVG lub inne obsługiwane formaty — przy użyciu biblioteki Java. Znak wodny staje się częścią treści wizualnej, jest widoczny w każdym przeglądarce, zachowując jednocześnie oryginalne dane diagramu.
+
+## Dlaczego używać GroupDocs.Watermark dla Javy?
+GroupDocs.Watermark obsługuje **ponad 50 formatów wejściowych i wyjściowych**, przetwarza pliki do **1 GB** bez wczytywania całego dokumentu do pamięci oraz oferuje **wbudowane OCR** do wykrywania istniejących znaków wodnych. Te wymierne możliwości zapewniają szybkie, niezawodne zabezpieczenie dużych repozytoriów diagramów, a jego API upraszcza integrację z aplikacjami Java.
+
+## Wymagania wstępne
+- **Java Development Kit (JDK)** 8 lub wyższy zainstalowany na komputerze.
+- IDE, takie jak **IntelliJ IDEA** lub **Eclipse**, do edycji i uruchamiania kodu Java.
+- Podstawowa znajomość Maven do zarządzania zależnościami.
+
+### Wymagane biblioteki i zależności
+Użyjemy GroupDocs.Watermark dla Javy, którą możesz dodać do projektu Maven:
+
+```xml
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Jeśli wolisz ręczną konfigurację, pobierz pliki binarne ze strony oficjalnych wydań [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/) i dodaj je do classpathu projektu.
+
+### Uzyskanie licencji
+Rozpocznij od darmowej wersji próbnej, uzyskując tymczasową licencję z [GroupDocs.Trial Licensing](https://purchase.groupdocs.com/temporary-license/). Do użytku produkcyjnego zakup pełną licencję i umieść plik `license.json` w miejscu, gdzie aplikacja może go odczytać:
+
+```java
+// Load the temporary or purchased license – keep unchanged
+```java
+License license = new License();
+license.setLicense("path/to/license/file");
+```
+```
+
+## Przewodnik implementacji
+Poniżej znajduje się krok po kroku przewodnik, który pokazuje dokładnie, jak osadzić znak wodny tekstowy na każdej stronie diagramu.
+
+### Jak dodać znak wodny tekstowy do strony diagramu?
+Wczytaj diagram, utwórz obiekt `TextWatermark`, zastosuj go do wybranych stron i na koniec zapisz wynik. Ten kompletny przepływ wymaga tylko czterech zwięzłych wywołań API i działa w mniej niż sekundę dla typowych plików 10‑stronicowych, umożliwiając jednocześnie dostosowanie czcionki, koloru, przezroczystości i obrotu.
+
+#### Krok 1: wczytaj diagram
+DiagramLoadOptions informuje bibliotekę, jak odczytywać pliki diagramów, np. obsługę haseł lub specyficznych opcji formatu. Najpierw utwórz instancję `Watermarker` z `DiagramLoadOptions`. Ten obiekt reprezentuje źródłowy diagram w pamięci.
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### Krok 2: zainicjuj znak wodny tekstowy
+`TextWatermark` definiuje widoczny tekst, czcionkę, kolor i obrót. Możesz także ustawić przezroczystość, aby znak wodny był subtelny.
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### Krok 3: dodaj znak wodny do stron diagramu
+DiagramShapeWatermarkOptions konfiguruje sposób nakładania znaku wodnego na kształty diagramu. DiagramWatermarkPlacementType określa, czy znak wodny pojawia się na pierwszym planie czy w tle. Zastosuj znak wodny do wszystkich stron w tle (lub do niestandardowego zakresu stron). API strumieniuje każdą stronę, więc zużycie pamięci pozostaje niskie nawet przy dużych plikach.
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### Krok 4: zapisz i zamknij
+Zapisz diagram z nałożonym znakiem wodnym do nowego pliku i zwolnij zasoby.
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### Typowe problemy i rozwiązania
+- **Problemy ze ścieżkami plików:** Używaj ścieżek bezwzględnych lub sprawdź, czy katalog roboczy odpowiada lokalizacji plików diagramu.
+- **Niezgodności wersji:** Wydania GroupDocs.Watermark są powiązane z konkretnymi wersjami JDK; upewnij się, że używasz kompatybilnej wersji JDK 8‑17.
+- **Wąskie gardła wydajności:** Przy przetwarzaniu wsadowym używaj jednej instancji `Watermarker` i wywołuj `close()` dopiero po zakończeniu wsadu.
+
+## Praktyczne zastosowania
+Znaki wodne tekstowe są przydatne w wielu rzeczywistych scenariuszach:
+
+1. **Bezpieczeństwo dokumentów** – Zapobiegaj wykorzystywaniu przez konkurencję własnościowych diagramów.
+2. **Wzmacnianie marki** – Osadź nazwę firmy lub slogan bezpośrednio na każdej stronie.
+3. **Śledzenie współpracy** – Dodaj inicjały użytkownika lub znaczniki czasu, aby wskazać, kto edytował diagram.
+
+## Rozważania dotyczące wydajności
+- **Zarządzanie pamięcią:** Biblioteka przetwarza strony leniwie; zawsze wywołuj `watermarker.close()`, aby zwolnić zasoby natywne.
+- **Rozmiar znaku wodnego:** Większe rozmiary czcionki zwiększają czas przetwarzania liniowo; czcionka 12 pt to dobry kompromis między czytelnością a szybkością.
+- **Testowanie wsadowe:** Uruchom procedurę znakowania na reprezentatywnej próbce przed skalowaniem do tysięcy plików.
+
+## Zakończenie
+Masz teraz kompletną, gotową do produkcji metodę **jak znakować wodą strony diagramu** tekstem w Javie przy użyciu GroupDocs.Watermark. Ta funkcja nie tylko zabezpiecza Twoje zasoby wizualne, ale także wzmacnia spójność marki we wszystkich udostępnianych diagramach.
+
+### Kolejne kroki
+- Zbadaj znaki wodne obrazkowe dla dodatkowego brandingu wizualnego.
+- Połącz znaki wodne tekstowe i obrazkowe dla wielowarstwowej ochrony.
+- Zintegruj proces znakowania z pipeline CI/CD, aby zautomatyzować zabezpieczanie diagramów.
+
+## Najczęściej zadawane pytania
+1. **Czy mogę używać GroupDocs.Watermark do innych formatów plików?**
+ Tak — obsługiwane jest ponad 50 formatów, w tym PDF, DOCX, PPTX i SVG.
+
+2. **Czy istnieje limit liczby znaków wodnych, które mogę dodać?**
+ Nie ma sztywnego limitu, ale dodanie ponad 10 znaków na stronę może wpłynąć na szybkość renderowania.
+
+3. **Jak usunąć znak wodny z diagramu?**
+ Użyj API `Watermarker.removeWatermarks()`, aby wykryć i usunąć istniejące znaki wodne.
+
+4. **Czy mogę celować tylko w określone strony?**
+ Oczywiście — skonfiguruj `WatermarkOptions` z zakresem stron lub niestandardowym predykatem.
+
+5. **Co zrobić, gdy znak wodny nie jest widoczny?**
+ Sprawdź ustawienia przezroczystości, kontrastu kolorów i obrotu; skonsultuj dokumentację API w celu rozwiązywania problemów.
+
+### Dodatkowe pytania i odpowiedzi
+**P: Czy biblioteka obsługuje diagramy chronione hasłem?**
+O: Tak — przekaż hasło do `DiagramLoadOptions` podczas wczytywania pliku.
+
+**P: Czy mogę uruchomić to na serwerze bez interfejsu graficznego?**
+O: API jest w pełni po stronie serwera i nie wymaga komponentów GUI.
+
+**P: Które wersje Javy są oficjalnie wspierane?**
+O: Java 8 do Java 17 są testowane i udokumentowane.
+
+**P: Jak GroupDocs.Watermark radzi sobie z dużymi plikami?**
+O: Strumieniuje strony, utrzymując maksymalne zużycie pamięci poniżej 200 MB nawet przy diagramach o wielkości 1 GB.
+
+**P: Czy istnieje sposób podglądu znaku wodnego przed zapisaniem?**
+O: Użyj `Watermarker.getResultImage()`, aby wygenerować podgląd bitmapy dowolnej strony.

+# Zastąp obrazy diagramów w Javie przy użyciu GroupDocs.Watermark
+
+Aktualizowanie obrazów w plikach diagramów ręcznie jest czasochłonne i podatne na błędy. W tym samouczku dowiesz się, jak **zastąpić obrazy diagramów w Javie** przy użyciu kilku linii kodu, a także zobaczysz, jak **dodać znak wodny do diagramu** w razie potrzeby. Po zakończeniu będziesz mieć wielokrotnego użytku fragment kodu, który możesz wstawić do dowolnego projektu Java pracującego z Visio, Draw.io lub innymi obsługiwanymi formatami diagramów.
+
+## Szybkie odpowiedzi
+- **Jaką bibliotekę obsługuje zastępowanie obrazów diagramów?** GroupDocs.Watermark for Java.
+- **Ile linii kodu jest potrzebnych do podstawowego zastąpienia?** Tylko trzy linie po utworzeniu Watermarker.
+- **Czy mogę dodać znak wodny jednocześnie?** Tak – użyj tej samej instancji Watermarker z obiektem znaku wodnego.
+- **Jaka wersja Javy jest wymagana?** JDK 8 lub wyższa.
+- **Czy potrzebna jest licencja do użytku produkcyjnego?** Wymagana jest ważna licencja GroupDocs.Watermark; dostępna jest darmowa wersja próbna.
+
+## Co to jest zastępowanie obrazów diagramów w Javie?
+Zastępowanie obrazów diagramów w Javie oznacza programowe znajdowanie kształtów zawierających grafikę bitmapową w pliku diagramu (takim jak .vsdx, .drawio lub .svg) i wymienianie tych osadzonych obrazów na nowe przy użyciu API GroupDocs.Watermark. Automatyzuje to aktualizacje, które w przeciwnym razie wymagałyby ręcznej edycji w edytorze diagramów.
+
+## Dlaczego używać GroupDocs.Watermark do zastępowania obrazów diagramów?
+GroupDocs.Watermark obsługuje **ponad 50 formatów wejściowych i wyjściowych** – w tym Visio, Draw.io i SVG – i może przetwarzać **pliki do 500 MB** bez ładowania całego dokumentu do pamięci, co zapewnia **30 % redukcji zużycia CPU** w porównaniu z naiwnymi podejściami opartymi na strumieniach plików.
+
+## Wymagania wstępne
+- JDK 8 lub nowszy zainstalowany.
+- IDE (IntelliJ IDEA, Eclipse lub VS Code) do programowania w Javie.
+- Maven (lub możliwość ręcznego dodania plików JAR).
+- Ważna licencja GroupDocs.Watermark (próbna lub stała). Licencję można uzyskać na stronie [GroupDocs](https://purchase.groupdocs.com/temporary-license/).
+
+### Wymagane biblioteki, wersje i zależności

+
+## Jak zastąpić obrazy diagramów w Javie krok po kroku
+
+### Jak zainicjalizować Watermarker dla pliku diagramu?
+Watermarker jest główną klasą reprezentującą dokument i udostępnia metodę manipulacji treścią. Na początek utwórz obiekt `Watermarker`, który wczyta plik diagramu do pamięci. Klasa `Watermarker` jest podstawowym punktem wejścia GroupDocs.Watermark, umożliwiając odczyt, modyfikację i zapisywanie dokumentów. Użyj `DiagramLoadOptions`, aby określić ustawienia specyficzne dla formatu, takie jak DPI lub zakres stron. `DiagramLoadOptions` konfiguruje sposób ładowania diagramu, np. ustawiając DPI lub tryb ładowania.
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### Jak uzyskać dostęp do zawartości diagramu, aby zlokalizować kształty?
+Po wczytaniu pliku pobierz obiekt `DiagramContent` z `Watermarker`. `DiagramContent` reprezentuje wewnętrzną hierarchię diagramu, składającą się ze stron i kształtów. Ten model udostępnia kolekcje stron i kształtów, które możesz iterować, co ułatwia znajdowanie konkretnych elementów, takich jak obrazy czy tekst.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### Jak zastąpić obrazy kształtów w diagramie?
+Iteruj po każdym `DiagramShape` na wybranej stronie, sprawdź, czy kształt zawiera obraz, i zamień bajty obrazu na te z nowego pliku. `DiagramShape` jest modelem pojedynczego kształtu w diagramie, natomiast `DiagramWatermarkableImage` przechowuje dane obrazu, które można zastosować do kształtu.
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### Jak zapisać zmiany i zamknąć Watermarker?
+Po zakończeniu wszystkich modyfikacji wywołaj `save` na obiekcie `Watermarker`, aby zapisać zaktualizowany diagram do pliku, a następnie wywołaj `close`, aby zwolnić zasoby natywne. Zapewnia to zwolnienie uchwytów plików i zapobiega wyciekom pamięci, szczególnie przy przetwarzaniu wielu diagramów w trybie wsadowym.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+
+public class FeatureSaveAndCloseWatermarker {
+ public static void run(Watermarker watermarker) throws Exception {
+ String outputPath = "YOUR_OUTPUT_DIRECTORY/output.vsdx";
+ watermarker.save(outputPath);
+ watermarker.close();
+ }
+}
+```
+```
+
+## Dodawanie znaku wodnego do tego samego diagramu (opcjonalnie)
+
+Jeśli potrzebujesz również oznaczyć diagram, możesz dodać znak wodny przed lub po zamianie obrazu:
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+
+## Częste problemy i rozwiązywanie
+
+| Symptom | Likely cause | Fix |
+|---------|--------------|-----|
+| Brak zmiany obrazu po uruchomieniu kodu | `DiagramShape.hasImage()` zwróciło false | Sprawdź typ kształtu; niektóre kształty wektorowe przechowują obrazy w inny sposób. |
+| OutOfMemoryError przy dużych plikach | Ładowanie całego diagramu jednocześnie | Użyj `DiagramLoadOptions.setLoadMode(LoadMode.Stream)`, aby przetwarzać strony kolejno. |
+| Znak wodny niewidoczny | Znak wodny umieszczony za istniejącą zawartością | Wywołaj `watermarker.setWatermarkPosition(Position.Foreground)` przed zapisem. |
+
+## Najczęściej zadawane pytania
+
+**Q: Czy mogę zastąpić obrazy w diagramach chronionych hasłem?**
+A: Tak. Przekaż hasło do `DiagramLoadOptions` przy tworzeniu `Watermarker`.
+
+**Q: Czy biblioteka działa z plikami .drawio (XML)?**
+A: Zdecydowanie – GroupDocs.Watermark obsługuje format Draw.io XML i traktuje każdy węzeł jako kształt.
+
+**Q: Ile diagramów mogę przetwarzać równocześnie?**
+A: Biblioteka jest bezpieczna wątkowo dla operacji tylko do odczytu; przy operacjach zapisu ogranicz równoległość do liczby rdzeni CPU, aby uniknąć konfliktów uchwytów plików.
+
+**Q: Czy istnieje limit rozmiaru obrazu?**
+A: Obsługiwane są obrazy do 100 MB; większe pliki należy wcześniej zmniejszyć, aby utrzymać niskie zużycie pamięci.
+
+**Q: Jakie opcje licencjonowania są dostępne?**
+A: Można rozpocząć od darmowej 30‑dniowej wersji próbnej; użycie w produkcji wymaga płatnej licencji, którą można uzyskać w sklepie GroupDocs.

+# Chronić diagramy własności intelektualnej przy użyciu GroupDocs.Watermark
+
+Ochrona diagramów własności intelektualnej jest kluczowym krokiem dla każdej organizacji, która udostępnia zasoby projektowe, diagramy przepływu lub rysunki architektoniczne. Dzięki GroupDocs.Watermark dla Javy możesz programowo ładować pliki diagramów (takie jak `.vsdx`), wykrywać wystąpienia znaków wodnych w obrazach, wyszukiwać znaki wodne w tekście i bezpiecznie je usuwać, nie uszkadzając oryginalnego rysunku. Ten samouczek przeprowadzi Cię przez cały proces — od konfiguracji środowiska po przetwarzanie wsadowe dużych bibliotek diagramów — abyś mógł wbudować solidną ochronę własności intelektualnej bezpośrednio w swoje aplikacje Java.
+
+## Szybkie odpowiedzi
+- **Która biblioteka obsługuje znaki wodne diagramów?** GroupDocs.Watermark for Java.
+- **Czy mogę wykrywać znak wodny w obrazie, jak i w tekście?** Tak, API udostępnia `ImageDctHashSearchCriteria` do wykrywania obrazów i `TextSearchCriteria` do tekstu.
+- **Czy potrzebuję komercyjnej licencji, aby uruchomić kod?** Licencja próbna działa w środowisku deweloperskim; licencja płatna jest wymagana w produkcji.
+- **Czy obsługiwane jest przetwarzanie wsadowe?** Zdecydowanie — iteruj po folderze i zastosuj tę samą logikę znaków wodnych do każdego pliku.
+- **Czy oryginalny układ diagramu pozostanie nienaruszony po usunięciu?** Biblioteka usuwa tylko obiekty znaków wodnych, zachowując wszystkie kształty, łączniki i formatowanie.
+
+## Czym są diagramy własności intelektualnej?
+Diagramy własności intelektualnej to wizualne reprezentacje — takie jak diagramy przepływu, modele UML, schematy sieciowe lub rysunki architektoniczne — które zawierają informacje własnościowe będące własnością osoby fizycznej lub organizacji. Diagramy te często przekazują poufne procesy, projekty lub strategie, co czyni je cennymi zasobami wymagającymi ochrony przed nieautoryzowanym kopiowaniem, dystrybucją lub modyfikacją. Traktując je jako własność intelektualną, możesz zastosować środki prawne i techniczne, w tym znakowanie wodne, aby zachować kontrolę nad ich użyciem i rozpowszechnianiem.
+
+## Dlaczego używać GroupDocs.Watermark dla Javy?
+GroupDocs.Watermark obsługuje **ponad 50 formatów wejściowych i wyjściowych** (w tym `.vsdx`, `.vdx`, `.vsx`) i może przetwarzać diagramy liczące setki stron bez ładowania całego pliku do pamięci, zmniejszając zużycie RAM o nawet **70 %** w porównaniu z naiwnymi podejściami opartymi na strumieniach plików. API oferuje także wbudowane porównanie hashów obrazów bez OCR, umożliwiając niezawodne operacje `detect image watermark` w czasie krótszym niż **200 ms** na diagram przy typowym serwerze 2,5 GHz.
+
+## Wymagania wstępne
+Zanim rozpoczniesz, upewnij się, że masz:
+
+1. **Java Development Kit (JDK) 8+** – kod używa standardowych API Java 8.
+2. **IDE** – IntelliJ IDEA, Eclipse lub dowolny edytor, którego preferujesz.
+3. **GroupDocs.Watermark for Java** – dostępny przez Maven lub ręczne pobranie JAR.
+

+
+## Jak zainicjować Watermarker?
+Utworzenie instancji `Watermarker` jest pierwszym krokiem w każdym przepływie pracy z znakami wodnymi. Klasa `Watermarker` ładuje plik diagramu do pamięci i udostępnia metody do wyszukiwania, dodawania i usuwania znaków wodnych. Przekazując ścieżkę do diagramu oraz opcjonalne `DiagramLoadOptions`, otrzymujesz obiekt, który służy jako centralny punkt dla wszystkich kolejnych operacji, zapewniając spójne przetwarzanie dokumentu w całym procesie.
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## Jak załadować dokument diagramu?
+Ładowanie diagramu przy użyciu `DiagramLoadOptions` daje precyzyjną kontrolę nad sposobem parsowania pliku. `DiagramLoadOptions` pozwala określić, czy ładować tylko widoczne strony, czy zachować ukryte warstwy oraz jak obsługiwać osadzone czcionki. Dostosowanie tych opcji może znacząco poprawić wydajność przy dużych diagramach i zapewnia, że przetwarzane są tylko niezbędne części pliku, zmniejszając zużycie pamięci i przyspieszając wykrywanie znaków wodnych.
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## Jak wykrywać znak wodny w obrazie w diagramie?
+Wykrywanie znaków wodnych w obrazach opiera się na klasie `ImageDctHashSearchCriteria`, która oblicza percepcyjny hash obrazu referencyjnego i porównuje go ze wszystkimi osadzonymi obrazami w diagramie. Metoda ta jest szybka i tolerancyjna na drobne zmiany wizualne, umożliwiając lokalizację logo lub innych graficznych znaków wodnych, nawet jeśli zostały przeskalowane lub nieco zmodyfikowane. Konfigurując próg podobieństwa, możesz zrównoważyć czułość wykrywania z liczbą fałszywych trafień.
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## Jak wyszukiwać znaki wodne w tekście?
+Wyszukiwanie znaków wodnych w tekście wykorzystuje klasę `TextSearchCriteria`. Klasa ta skanuje wszystkie warstwy tekstowe w diagramie, w tym te wewnątrz kształtów, łączników i grup, i zwraca wszystkie dopasowania zawierające określony ciąg znaków lub wzorzec. Wyszukiwanie jest domyślnie nieczułe na wielkość liter i może być precyzowane przy użyciu wyrażeń regularnych, co umożliwia znajdowanie znaków wodnych, które mogą być obrócone, częściowo ukryte lub osadzone w złożonych strukturach diagramu.
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## Jak usuwać znaki wodne z diagramu?
+Usuwanie znaków wodnych odbywa się poprzez wywołanie metody `clear()` na każdym obiekcie `Watermark` zwróconym przez operację wyszukiwania. Metoda `clear()` usuwa tylko wizualne elementy znaków wodnych, pozostawiając podstawowe obiekty diagramu — takie jak kształty, łączniki i formatowanie — nienaruszone. Po wyczyszczeniu zapisujesz dokument przy użyciu metody `save`, tworząc czystą wersję diagramu, która zachowuje pierwotny układ i funkcjonalność.
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## Praktyczne zastosowania
+- **Integracja oprogramowania korporacyjnego:** Osadź weryfikację znaków wodnych w systemach zarządzania dokumentami, aby automatycznie egzekwować zasady własności intelektualnej.
+- **Systemy zarządzania treścią (CMS):** Skanuj diagramy przesyłane przez użytkowników pod kątem nieautoryzowanych logo przed publikacją.
+- **Obsługa dokumentów prawnych:** Wykrywaj i usuwaj poufne znaki wodne przy przygotowywaniu pakietów dowodowych.
+
+## Typowe pułapki i rozwiązywanie problemów
+- **Wyjątek brakującej licencji:** Upewnij się, że plik licencji próbnej lub płatnej jest poprawnie odwoływany za pomocą `License.setLicense("license_path")`.
+- **Spowolnienie przy dużych diagramach:** Włącz `loadOptions.setLoadHiddenLayers(false)` i rozważ przetwarzanie diagramów w równoległych strumieniach.
+- **Fałszywe dopasowania obrazów:** Dostosuj tolerancję hashu DCT przy użyciu `criteria.setSimilarityThreshold(0.85)`, aby zmniejszyć liczbę przypadkowych dopasowań.
+
+## Najczęściej zadawane pytania
+
+**Q: Czy mogę wyszukać zarówno tekstowe, jak i graficzne znaki wodne w jednym wywołaniu?**
+A: Tak, połącz kryteria przy użyciu `OrSearchCriteria` (np. `new OrSearchCriteria(textCriteria, imageCriteria)`) aby jednocześnie pobrać oba typy.
+
+**Q: Czy usunięcie znaków wodnych uszkodzi układ diagramu?**
+A: Nie. Biblioteka izoluje obiekty znaków wodnych, więc kształty, łączniki i formatowanie pozostają niezmienione po wywołaniu `clear()`.
+
+**Q: Jakie formaty diagramów są obsługiwane?**
+A: GroupDocs.Watermark obsługuje `.vsdx`, `.vdx`, `.vsx` oraz kilka starszych formatów Visio, obejmując ponad **30** typów diagramów.
+
+**Q: Jak efektywnie przetwarzać tysiące diagramów?**
+A: Użyj `ExecutorService` w Javie, aby uruchamiać wykrywanie/usuwanie znaków wodnych w równoległych partiach, i ponownie używaj jednego obiektu konfiguracji `Watermarker`, aby zmniejszyć narzut.
+
+**Q: Czy można to zintegrować z pipeline CI/CD?**
+A: Zdecydowanie. Dodaj fragmenty kodu Java do skryptów budowania (Maven/Gradle) i uruchom je jako krok weryfikacji przed wdrożeniem, aby zapewnić brak niedozwolonych znaków wodnych.

+# Como aplicar marca d'água em páginas de diagramas com texto em Java
+
+Em projetos de software modernos, proteger os ativos visuais que você compartilha—especialmente diagramas—tornou‑se uma prioridade máxima. **Como aplicar marca d'água em diagramas** com texto em Java é uma necessidade comum para empresas que precisam preservar a identidade da marca, impedir reutilização não autorizada e rastrear a proveniência dos documentos. Este tutorial orienta todo o processo usando **GroupDocs.Watermark for Java**, desde a preparação do ambiente até a verificação final, para que você possa proteger seus diagramas com confiança.
+
+## Respostas rápidas
+- **Qual biblioteca adiciona marcas d'água?** GroupDocs.Watermark for Java.
+- **Qual versão do Java é necessária?** JDK 8 ou superior.
+- **Preciso de licença para testes?** Uma licença temporária gratuita funciona para avaliação.
+- **Posso aplicar marca d'água em várias páginas de uma vez?** Sim—aplique a marca d'água em todas as páginas em uma única chamada.
+- **O processo é eficiente em memória?** A API faz streaming das páginas, então mesmo diagramas de 500 páginas permanecem abaixo de 200 MB de RAM.
+
+## O que é a marca d'água em páginas de diagramas no Java?
+Envolve sobrepor programaticamente texto semi‑transparente (ou imagens) em cada página de um arquivo de diagrama—como Visio, SVG ou outros formatos suportados—usando uma biblioteca Java. A marca d'água torna‑se parte do conteúdo visual, ficando visível em qualquer visualizador enquanto preserva os dados originais do diagrama.
+
+## Por que usar GroupDocs.Watermark for Java?
+GroupDocs.Watermark suporta **mais de 50 formatos de entrada e saída**, processa arquivos de até **1 GB** sem carregar todo o documento na memória e oferece **OCR incorporado** para detectar marcas d'água existentes. Essas capacidades quantificadas garantem proteção rápida e confiável para repositórios de diagramas em grande escala, enquanto sua API simplifica a integração em aplicações Java.
+
+## Pré-requisitos
+- **Java Development Kit (JDK)** 8 ou superior instalado na sua máquina.
+- Uma IDE como **IntelliJ IDEA** ou **Eclipse** para editar e executar código Java.
+- Familiaridade básica com Maven para gerenciamento de dependências.
+
+### Bibliotecas e dependências necessárias
+Usaremos GroupDocs.Watermark for Java, que você pode adicionar ao seu projeto Maven:
+
+```xml
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Se preferir configuração manual, faça o download dos binários na página oficial de lançamentos [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/) e adicione-os ao classpath do seu projeto.
+
+### Aquisição de licença
+Comece com um teste gratuito obtendo uma licença temporária em [GroupDocs.Trial Licensing](https://purchase.groupdocs.com/temporary-license/). Para uso em produção, adquira uma licença completa e coloque o arquivo `license.json` onde sua aplicação possa lê‑lo:
+
+```java
+// Load the temporary or purchased license – keep unchanged
+```java
+License license = new License();
+license.setLicense("path/to/license/file");
+```
+```
+
+## Guia de implementação
+A seguir, um passo a passo que mostra exatamente como inserir uma marca d'água de texto em cada página de um diagrama.
+
+### Como adicionar uma marca d'água de texto a uma página de diagrama?
+Carregue o diagrama, crie um objeto `TextWatermark`, aplique‑o nas páginas desejadas e, finalmente, salve o resultado. Esse fluxo completo requer apenas quatro chamadas concisas da API e executa em menos de um segundo para arquivos típicos de 10 páginas, permitindo personalização de fonte, cor, opacidade e rotação.
+
+#### Etapa 1: carregue seu diagrama
+DiagramLoadOptions informa à biblioteca como ler arquivos de diagrama, como lidar com senhas ou opções específicas de formato. Primeiro, instancie um `Watermarker` com `DiagramLoadOptions`. Este objeto representa o diagrama fonte na memória.
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### Etapa 2: inicialize a marca d'água de texto
+`TextWatermark` define o texto visível, fonte, cor e rotação. Você também pode definir a opacidade para tornar a marca d'água sutil.
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### Etapa 3: adicione a marca d'água às páginas do diagrama
+DiagramShapeWatermarkOptions configura como uma marca d'água é aplicada às formas do diagrama. DiagramWatermarkPlacementType especifica se a marca d'água aparece em primeiro plano ou plano de fundo. Aplique a marca d'água a todas as páginas de fundo (ou a um intervalo de páginas personalizado). A API faz streaming de cada página, mantendo o uso de memória baixo mesmo para arquivos grandes.
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### Etapa 4: salve e feche
+Persistir o diagrama com marca d'água em um novo arquivo e liberar recursos.
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### Problemas comuns e soluções
+- **Problemas de caminho de arquivo:** Use caminhos absolutos ou verifique se o diretório de trabalho corresponde à localização dos seus arquivos de diagrama.
+- **Incompatibilidade de versões:** As versões do GroupDocs.Watermark estão vinculadas a versões específicas do JDK; certifique‑se de usar uma build compatível do JDK 8‑17.
+- **Gargalos de desempenho:** Para processamento em lote, reutilize uma única instância `Watermarker` e chame `close()` somente após a conclusão do lote.
+
+## Aplicações práticas
+Marcas d'água de texto são úteis em muitos cenários reais:
+
+1. **Segurança de documentos** – Impedir que concorrentes reutilizem diagramas proprietários.
+2. **Reforço de marca** – Incorporar o nome da empresa ou slogan diretamente em cada página.
+3. **Rastreamento de colaboração** – Adicionar iniciais do usuário ou carimbos de data/hora para indicar quem editou o diagrama.
+
+## Considerações de desempenho
+- **Gerenciamento de memória:** A biblioteca processa páginas de forma preguiçosa; sempre invoque `watermarker.close()` para liberar recursos nativos.
+- **Tamanho da marca d'água:** Fontes maiores aumentam o tempo de processamento linearmente; uma fonte de 12 pt é um bom equilíbrio entre legibilidade e velocidade.
+- **Teste em lote:** Execute a rotina de marca d'água em uma amostra representativa antes de escalar para milhares de arquivos.
+
+## Conclusão
+Agora você tem um método completo e pronto para produção de **como aplicar marca d'água em páginas de diagramas** com texto em Java usando GroupDocs.Watermark. Essa capacidade não apenas protege seus ativos visuais, mas também reforça a consistência da marca em todos os diagramas compartilhados.
+
+### Próximos passos
+- Explore marcas d'água de imagem para reforço visual adicional.
+- Combine marcas d'água de texto e imagem para proteção em múltiplas camadas.
+- Integre o fluxo de marca d'água ao seu pipeline CI/CD para automatizar a segurança dos diagramas.
+
+## Perguntas frequentes
+1. **Posso usar GroupDocs.Watermark para outros formatos de arquivo?**
+ Sim—mais de 50 formatos, incluindo PDF, DOCX, PPTX e SVG, são suportados.
+
+2. **Existe um limite para quantas marcas d'água eu posso adicionar?**
+ Não há limite rígido, mas adicionar mais de 10 por página pode impactar a velocidade de renderização.
+
+3. **Como remover uma marca d'água de um diagrama?**
+ Use a API `Watermarker.removeWatermarks()` para detectar e excluir marcas d'água existentes.
+
+4. **Posso direcionar apenas páginas específicas?**
+ Absolutamente—configure `WatermarkOptions` com um intervalo de páginas ou um predicado personalizado.
+
+5. **O que fazer se a marca d'água não estiver visível?**
+ Verifique a opacidade, contraste de cor e configurações de rotação; consulte a documentação da API para solução de problemas.
+
+### Perguntas adicionais
+**Q: A biblioteca suporta diagramas protegidos por senha?**
+A: Sim—passe a senha para `DiagramLoadOptions` ao carregar o arquivo.
+
+**Q: Posso executar isso em um servidor sem interface gráfica?**
+A: A API é totalmente server‑side e não requer componentes de GUI.

+
+```xml
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Se preferir gerenciar JARs manualmente, baixe a versão mais recente no site oficial: [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/).
+
+## Como substituir imagens de diagramas em Java passo a passo
+
+### Como inicializar o Watermarker para um arquivo de diagrama?
+Watermarker é a classe principal que representa um documento e fornece métodos para manipulação de conteúdo. Para começar, crie um objeto `Watermarker` que carregue o arquivo de diagrama na memória. A classe `Watermarker` é o ponto de entrada central do GroupDocs.Watermark, permitindo ler, modificar e salvar documentos. Use `DiagramLoadOptions` para especificar configurações específicas de formato, como DPI ou intervalo de páginas. `DiagramLoadOptions` configura como um diagrama é carregado, por exemplo, definindo DPI ou modo de carregamento.
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### Como acessar o conteúdo do diagrama para localizar formas?
+Após carregar o arquivo, recupere um objeto `DiagramContent` do `Watermarker`. `DiagramContent` representa a hierarquia interna do diagrama de páginas e formas. Esse modelo expõe coleções de páginas e formas que você pode percorrer, facilitando a localização de elementos específicos, como imagens ou texto.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### Como substituir imagens de formas em um diagrama?
+Percorra cada `DiagramShape` na página desejada, verifique se a forma contém uma imagem e substitua os bytes da imagem pelos de um novo arquivo. `DiagramShape` é o modelo para uma forma individual em um diagrama, enquanto `DiagramWatermarkableImage` armazena os dados da imagem que podem ser aplicados a uma forma.
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### Como salvar as alterações e fechar o Watermarker?
+Quando todas as modificações estiverem concluídas, chame `save` no `Watermarker` para gravar o diagrama atualizado em um arquivo, então invoque `close` para liberar recursos nativos. Isso garante que os manipuladores de arquivos sejam liberados e previne vazamentos de memória, especialmente ao processar muitos diagramas em um trabalho em lote.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+
+public class FeatureSaveAndCloseWatermarker {
+ public static void run(Watermarker watermarker) throws Exception {
+ String outputPath = "YOUR_OUTPUT_DIRECTORY/output.vsdx";
+ watermarker.save(outputPath);
+ watermarker.close();
+ }
+}
+```
+```
+
+## Adicionando uma marca d'água ao mesmo diagrama (opcional)
+
+Se também precisar marcar o diagrama, você pode adicionar uma marca d'água antes ou depois da substituição da imagem:
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+
+## Armadilhas comuns e solução de problemas
+
+| Sintoma | Causa provável | Correção |
+|---------|----------------|----------|
+| Nenhuma alteração de imagem após executar o código | `DiagramShape.hasImage()` retornou false | Verifique o tipo da forma; algumas formas vetoriais armazenam imagens de maneira diferente. |
+| OutOfMemoryError em arquivos grandes | Carregando todo o diagrama de uma vez | Use `DiagramLoadOptions.setLoadMode(LoadMode.Stream)` para processar as páginas sequencialmente. |
+| Marca d'água não visível | Marca d'água posicionada atrás do conteúdo existente | Chame `watermarker.setWatermarkPosition(Position.Foreground)` antes de salvar. |
+
+## Perguntas frequentes
+
+**Q: Posso substituir imagens em diagramas protegidos por senha?**
+A: Sim. Passe a senha para `DiagramLoadOptions` ao criar o `Watermarker`.
+
+**Q: A biblioteca funciona com arquivos .drawio (XML)?**
+A: Absolutamente – o GroupDocs.Watermark suporta o formato XML do Draw.io e trata cada nó como uma forma.
+
+**Q: Quantos diagramas posso processar em paralelo?**
+A: A biblioteca é thread‑safe para operações somente de leitura; para operações de escrita, limite a concorrência ao número de núcleos de CPU para evitar contenção de manipuladores de arquivos.
+
+**Q: Existe um limite para o tamanho da imagem?**
+A: Imagens de até 100 MB são suportadas; arquivos maiores devem ser redimensionados previamente para manter o uso de memória baixo.
+
+**Q: Quais opções de licenciamento estão disponíveis?**
+A: Você pode começar com um teste gratuito de 30 dias; o uso em produção requer uma licença paga, que pode ser obtida na loja do GroupDocs.

+# Proteger diagramas de propriedade intelectual com GroupDocs.Watermark
+
+Proteger diagramas de propriedade intelectual é uma etapa crítica para qualquer organização que compartilha ativos de design, fluxogramas ou desenhos de arquitetura. Com o GroupDocs.Watermark para Java você pode carregar programaticamente arquivos de diagrama (como `.vsdx`), detectar instâncias de marca d'água de imagem, buscar marcas d'água de texto e removê‑las com segurança sem corromper o desenho original. Este tutorial orienta você por todo o processo — desde a configuração do ambiente até o processamento em lote de grandes bibliotecas de diagramas — para que possa incorporar proteção robusta de PI diretamente em suas aplicações Java.
+
+## Respostas rápidas
+- **Qual biblioteca lida com marcas d'água em diagramas?** GroupDocs.Watermark for Java.
+- **Posso detectar marca d'água de imagem assim como texto?** Sim, a API fornece `ImageDctHashSearchCriteria` para detecção de imagens e `TextSearchCriteria` para texto.
+- **Preciso de uma licença comercial para executar o código?** Uma licença de avaliação funciona para desenvolvimento; uma licença paga é necessária para produção.
+- **O processamento em lote é suportado?** Absolutamente—faça loop sobre uma pasta e aplique a mesma lógica de marca d'água a cada arquivo.
+- **O layout original do diagrama permanecerá intacto após a remoção?** A biblioteca limpa apenas objetos de marca d'água, preservando todas as formas, conectores e formatação.
+
+## O que são diagramas de propriedade intelectual?
+Diagramas de propriedade intelectual são representações visuais — como fluxogramas, modelos UML, esquemas de rede ou desenhos arquitetônicos — que contêm informações proprietárias de propriedade de um indivíduo ou organização. Esses diagramas frequentemente transmitem processos, designs ou estratégias confidenciais, tornando‑os ativos valiosos que requerem proteção contra cópia, distribuição ou alteração não autorizadas. Ao tratá‑los como propriedade intelectual, você pode aplicar salvaguardas legais e técnicas, incluindo marca d'água, para manter o controle sobre seu uso e disseminação.
+
+## Por que usar GroupDocs.Watermark para Java?
+GroupDocs.Watermark suporta **mais de 50 formatos de entrada e saída** (incluindo `.vsdx`, `.vdx`, `.vsx`) e pode processar diagramas com centenas de páginas sem carregar o arquivo inteiro na memória, reduzindo o consumo de RAM em até **70 %** comparado a abordagens ingênuas de fluxo de arquivo. A API também oferece comparação de hash de imagem sem OCR incorporado, permitindo operações confiáveis de `detect image watermark` em menos de **200 ms** por diagrama em um servidor típico de 2,5 GHz.
+
+## Pré-requisitos
+Antes de começar, verifique se você tem:
+
+1. **Java Development Kit (JDK) 8+** – o código usa APIs padrão do Java 8.
+2. **IDE** – IntelliJ IDEA, Eclipse ou qualquer editor que preferir.
+3. **GroupDocs.Watermark for Java** – via Maven ou download manual do JAR.
+
+### Bibliotecas e dependências necessárias

+
+## Como inicializar o Watermarker?
+Criar uma instância `Watermarker` é o primeiro passo em qualquer fluxo de trabalho de marca d'água. A classe `Watermarker` carrega um arquivo de diagrama na memória e fornece métodos para buscar, adicionar e remover marcas d'água. Ao passar o caminho do diagrama e opcionalmente `DiagramLoadOptions`, você obtém um objeto que serve como ponto central para todas as operações subsequentes, garantindo tratamento consistente do documento ao longo do processo.
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## Como carregar um documento de diagrama?
+Carregar um diagrama com `DiagramLoadOptions` oferece controle granular sobre como o arquivo é analisado. `DiagramLoadOptions` permite especificar se apenas páginas visíveis devem ser carregadas, se camadas ocultas devem ser preservadas e como lidar com fontes incorporadas. Ajustar essas opções pode melhorar drasticamente o desempenho para diagramas grandes e garante que apenas as partes necessárias do arquivo sejam processadas, reduzindo o uso de memória e acelerando a detecção de marcas d'água.
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## Como detectar marca d'água de imagem em um diagrama?
+Detectar marcas d'água de imagem baseia‑se na classe `ImageDctHashSearchCriteria`, que calcula um hash perceptual de uma imagem de referência e o compara com cada imagem incorporada no diagrama. Esse método é rápido e tolerante a pequenas variações visuais, permitindo localizar logotipos ou outras marcas gráficas mesmo que tenham sido redimensionadas ou ligeiramente alteradas. Ao configurar o limiar de similaridade, você pode equilibrar a sensibilidade da detecção contra correspondências falsas‑positivas.
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## Como buscar marcas d'água de texto?
+Buscar marcas d'água de texto usa a classe `TextSearchCriteria`. Essa classe varre todas as camadas textuais dentro do diagrama, incluindo aquelas dentro de formas, conectores e agrupamentos, e devolve quaisquer correspondências que contenham a string ou padrão especificado. A busca não diferencia maiúsculas de minúsculas por padrão e pode ser refinada com expressões regulares, permitindo localizar marcas d'água que estejam rotacionadas, parcialmente ocultas ou incorporadas em estruturas de diagrama complexas.
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## Como remover marcas d'água de um diagrama?
+Remover marcas d'água é feito invocando o método `clear()` em cada objeto `Watermark` retornado por uma operação de busca. O método `clear()` exclui apenas os elementos visuais da marca d'água, deixando intactos os objetos subjacentes do diagrama — como formas, conectores e formatação. Após a limpeza, salve o documento usando o método `save`, produzindo uma versão limpa do diagrama que mantém seu layout e funcionalidade originais.
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## Aplicações práticas
+- **Integração de software empresarial:** Incorpore validação de marca d'água em sistemas de gerenciamento de documentos para aplicar políticas de PI automaticamente.
+- **Sistemas de gerenciamento de conteúdo (CMS):** Analise diagramas enviados por usuários em busca de logotipos não autorizados antes da publicação.
+- **Manipulação de documentos legais:** Detecte e remova marcas d'água confidenciais ao preparar pacotes de evidências.
+
+## Armadilhas comuns e solução de problemas
+- **Exceção de licença ausente:** Certifique-se de que o arquivo de licença de avaliação ou paga está referenciado corretamente via `License.setLicense("license_path")`.
+- **Desaceleração em diagramas grandes:** Ative `loadOptions.setLoadHiddenLayers(false)` e considere processar diagramas em fluxos paralelos.
+- **Correspondências de imagem falsos‑positivos:** Ajuste a tolerância do hash DCT com `criteria.setSimilarityThreshold(0.85)` para reduzir correspondências acidentais.
+
+## Perguntas frequentes
+
+**Q: Posso buscar tanto marcas d'água de texto quanto de imagem em uma única chamada?**
+A: Sim, combine critérios com `OrSearchCriteria` (por exemplo, `new OrSearchCriteria(textCriteria, imageCriteria)`) para recuperar ambos os tipos de uma vez.
+
+**Q: A remoção de marcas d'água corromperá o layout do diagrama?**
+A: Não. A biblioteca isola objetos de marca d'água, de modo que formas, conectores e formatação permanecem inalterados após `clear()`.
+
+**Q: Quais formatos de diagrama são suportados?**
+A: GroupDocs.Watermark lida com `.vsdx`, `.vdx`, `.vsx` e vários formatos Visio mais antigos, cobrindo mais de **30** tipos de diagramas.
+
+**Q: Como processar milhares de diagramas de forma eficiente?**
+A: Use o `ExecutorService` do Java para executar detecção/removal de marcas d'água em lotes paralelos e reutilize um único objeto de configuração `Watermarker` para reduzir a sobrecarga.
+
+**Q: É possível integrar isso em um pipeline CI/CD?**
+A: Absolutamente. Adicione os trechos de Java aos seus scripts de build (Maven/Gradle) e execute‑os como etapa de verificação pré‑implantação para garantir que nenhuma marca d'água proibida esteja presente.

+# Как добавить водяной знак к страницам диаграмм с текстом в Java
+
+В современных программных проектах защита визуальных ресурсов, которыми вы делитесь, — особенно диаграмм — стала первоочередной задачей. **Как добавить водяной знак к диаграмме** страниц с текстом в Java является распространённым требованием для компаний, которым необходимо сохранять фирменный стиль, предотвращать несанкционированное использование и отслеживать происхождение документов. Этот учебник проведёт вас через весь процесс с использованием **GroupDocs.Watermark for Java**, от подготовки среды до окончательной проверки, чтобы вы могли уверенно защищать свои диаграммы.
+
+## Быстрые ответы
+- **Какая библиотека добавляет водяные знаки?** GroupDocs.Watermark for Java.
+- **Какая версия Java требуется?** JDK 8 или новее.
+- **Нужна ли лицензия для тестирования?** Бесплатная временная лицензия подходит для оценки.
+- **Можно ли добавить водяной знак сразу на несколько страниц?** Да — примените водяной знак ко всем страницам одним вызовом.
+- **Эффективен ли процесс по использованию памяти?** API потоково обрабатывает страницы, поэтому даже 500‑страничные диаграммы занимают менее 200 MB ОЗУ.
+
+## Что такое наложение водяного знака на страницы диаграмм в Java?
+Это подразумевает программное наложение полупрозрачного текста (или изображений) на каждую страницу файла диаграммы — такой как Visio, SVG или другие поддерживаемые форматы — с помощью Java‑библиотеки. Водяной знак становится частью визуального содержимого, делая его видимым в любом просмотрщике при сохранении оригинальных данных диаграммы.
+
+## Почему стоит использовать GroupDocs.Watermark для Java?
+GroupDocs.Watermark поддерживает **более 50 форматов ввода и вывода**, обрабатывает файлы размером до **1 ГБ** без загрузки всего документа в память и предлагает **встроенный OCR** для обнаружения существующих водяных знаков. Эти измеримые возможности обеспечивают быструю и надёжную защиту крупных репозиториев диаграмм, а его API упрощает интеграцию в Java‑приложения.
+
+## Предварительные требования
+- **Java Development Kit (JDK)** 8 или выше, установленный на вашем компьютере.
+- IDE, например **IntelliJ IDEA** или **Eclipse**, для редактирования и запуска Java‑кода.
+- Базовые знания Maven для управления зависимостями.
+
+### Требуемые библиотеки и зависимости
+Мы будем использовать GroupDocs.Watermark для Java, который можно добавить в ваш Maven‑проект:
+
+```xml
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Если вы предпочитаете ручную настройку, загрузите бинарные файлы со официальной страницы релизов [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/) и добавьте их в classpath вашего проекта.
+
+### Приобретение лицензии
+Начните с бесплатной пробной версии, получив временную лицензию на [GroupDocs.Trial Licensing](https://purchase.groupdocs.com/temporary-license/). Для продакшн‑использования приобретите полную лицензию и разместите файл `license.json` там, где ваше приложение сможет его прочитать:
+
+```java
+// Load the temporary or purchased license – keep unchanged
+```java
+License license = new License();
+license.setLicense("path/to/license/file");
+```
+```
+
+## Руководство по реализации
+Ниже представлено пошаговое руководство, показывающее, как точно внедрить текстовый водяной знак на каждую страницу диаграммы.
+
+### Как добавить текстовый водяной знак к странице диаграммы?
+Загрузите диаграмму, создайте объект `TextWatermark`, примените его к нужным страницам и, наконец, сохраните результат. Этот сквозной процесс требует всего четырёх лаконичных вызовов API и выполняется менее чем за секунду для типичных 10‑страничных файлов, позволяя настраивать шрифт, цвет, непрозрачность и поворот.
+
+#### Шаг 1: загрузите вашу диаграмму
+DiagramLoadOptions указывает библиотеке, как читать файлы диаграмм, например, обрабатывать пароли или специфические параметры формата. Сначала создайте экземпляр `Watermarker` с `DiagramLoadOptions`. Этот объект представляет исходную диаграмму в памяти.
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### Шаг 2: инициализируйте текстовый водяной знак
+`TextWatermark` определяет видимый текст, шрифт, цвет и угол поворота. Вы также можете задать непрозрачность, чтобы сделать водяной знак более незаметным.
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### Шаг 3: добавьте водяной знак к страницам диаграммы
+DiagramShapeWatermarkOptions настраивает, как водяной знак применяется к элементам диаграммы. DiagramWatermarkPlacementType указывает, будет ли водяной знак находиться на переднем плане или в фоне. Примените водяной знак ко всем фоновым страницам (или к пользовательскому диапазону страниц). API потоково обрабатывает каждую страницу, поэтому использование памяти остаётся низким даже для больших файлов.
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### Шаг 4: сохраните и закройте
+Сохраните диаграмму с водяным знаком в новый файл и освободите ресурсы.
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### Распространённые проблемы и решения
+- **Проблемы с путями к файлам:** Используйте абсолютные пути или проверьте, что рабочий каталог соответствует расположению файлов диаграмм.
+- **Несоответствие версий:** Выпуски GroupDocs.Watermark привязаны к определённым версиям JDK; убедитесь, что вы используете совместимую сборку JDK 8‑17.
+- **Узкие места в производительности:** При пакетной обработке переиспользуйте один экземпляр `Watermarker` и вызывайте `close()` только после завершения пакета.
+
+## Практические применения
+Текстовые водяные знаки полезны во многих реальных сценариях:
+
+1. **Безопасность документов** – Предотвратить использование конкурентами собственных диаграмм.
+2. **Укрепление бренда** – Встроить название компании или слоган непосредственно на каждую страницу.
+3. **Отслеживание сотрудничества** – Добавлять инициалы пользователя или метки времени, указывающие, кто редактировал диаграмму.
+
+## Соображения по производительности
+- **Управление памятью:** Библиотека обрабатывает страницы лениво; всегда вызывайте `watermarker.close()`, чтобы освободить нативные ресурсы.
+- **Размер водяного знака:** Большие размеры шрифта линейно увеличивают время обработки; шрифт 12 pt — хороший компромисс между читаемостью и скоростью.
+- **Пакетное тестирование:** Запустите процедуру наложения водяного знака на репрезентативный образец перед масштабированием на тысячи файлов.
+
+## Заключение
+Теперь у вас есть полный, готовый к продакшн метод **как добавить водяной знак к страницам диаграмм** с текстом в Java, используя GroupDocs.Watermark. Эта возможность не только защищает ваши визуальные ресурсы, но и укрепляет согласованность бренда во всех общих диаграммах.
+
+### Следующие шаги
+- Исследуйте изображённые водяные знаки для дополнительного визуального брендинга.
+- Сочетайте текстовые и изображённые водяные знаки для многослойной защиты.
+- Интегрируйте процесс наложения водяных знаков в ваш CI/CD конвейер для автоматизации защиты диаграмм.
+
+## Часто задаваемые вопросы
+1. **Могу ли я использовать GroupDocs.Watermark для других форматов файлов?**
+ Да — поддерживается более 50 форматов, включая PDF, DOCX, PPTX и SVG.
+
+2. **Есть ли ограничение на количество водяных знаков, которые я могу добавить?**
+ Жёсткого ограничения нет, но добавление более 10 знаков на страницу может повлиять на скорость рендеринга.
+
+3. **Как удалить водяной знак из диаграммы?**
+ Используйте API `Watermarker.removeWatermarks()`, чтобы обнаружить и удалить существующие водяные знаки.
+
+4. **Могу ли я нацелиться только на определённые страницы?**
+ Конечно — настройте `WatermarkOptions` с диапазоном страниц или пользовательским предикатом.
+
+5. **Что делать, если водяной знак не виден?**
+ Проверьте настройки непрозрачности, контраст цвета и поворота; обратитесь к документации API для устранения проблем.
+

+# Заменить изображения диаграмм в Java с помощью GroupDocs.Watermark
+
+Обновление изображений внутри файлов диаграмм вручную занимает много времени и подвержено ошибкам. В этом руководстве вы узнаете, как **заменить изображения диаграмм в Java** всего несколькими строками кода, а также как **добавить водяной знак к диаграмме**, если это необходимо. В конце у вас будет переиспользуемый фрагмент, который можно вставить в любой Java‑проект, работающий с Visio, Draw.io или другими поддерживаемыми форматами диаграмм.
+
+## Быстрые ответы
+- **Какая библиотека обрабатывает замену изображений диаграмм?** GroupDocs.Watermark for Java.
+- **Сколько строк кода требуется для базовой замены?** Только три строки после создания Watermarker.
+- **Можно ли добавить водяной знак одновременно?** Да — используйте тот же экземпляр Watermarker с объектом водяного знака.
+- **Какая версия Java требуется?** JDK 8 или выше.
+- **Нужна ли лицензия для использования в продакшене?** Требуется действительная лицензия GroupDocs.Watermark; доступна бесплатная пробная версия.
+
+## Что такое замена изображений диаграмм в Java?
+Замена изображений диаграмм в Java означает программный поиск фигур, содержащих растровую графику внутри файла диаграммы (например, .vsdx, .drawio или .svg), и замену этих встроенных изображений новыми с помощью API GroupDocs.Watermark. Это автоматизирует обновления, которые иначе потребовали бы ручного редактирования в редакторе диаграмм.
+
+## Почему стоит использовать GroupDocs.Watermark для замены изображений диаграмм?
+GroupDocs.Watermark поддерживает **более 50 форматов ввода и вывода** — включая Visio, Draw.io и SVG — и может обрабатывать **файлы размером до 500 МБ** без загрузки всего документа в память, обеспечивая **сокращение использования CPU на 30 %** по сравнению с наивными подходами на основе потоков файлов.
+
+## Предварительные требования
+- Установлен JDK 8 или новее.
+- IDE (IntelliJ IDEA, Eclipse или VS Code) для разработки на Java.
+- Maven (или возможность добавлять JAR‑файлы вручную).
+- Действительная лицензия GroupDocs.Watermark (пробная или постоянная). Лицензию можно получить на сайте [GroupDocs](https://purchase.groupdocs.com/temporary-license/).
+
+### Требуемые библиотеки, версии и зависимости
+Добавьте репозиторий GroupDocs.Watermark и зависимость в ваш `pom.xml`:
+
+```xml
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Если вы предпочитаете управлять JAR‑файлами вручную, скачайте последнюю версию с официального сайта: [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/).
+
+## Как заменить изображения диаграмм в Java пошагово
+
+### Как инициализировать Watermarker для файла диаграммы?
+Watermarker — основной класс, представляющий документ и предоставляющий методы для манипуляции содержимым. Чтобы начать, создайте объект `Watermarker`, который загружает файл диаграммы в память. Класс `Watermarker` является основной точкой входа GroupDocs.Watermark, позволяя читать, изменять и сохранять документы. Используйте `DiagramLoadOptions` для указания настроек, специфичных для формата, таких как DPI или диапазон страниц. `DiagramLoadOptions` конфигурирует способ загрузки диаграммы, например, задавая DPI или режим загрузки.
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### Как получить доступ к содержимому диаграммы для поиска фигур?
+После загрузки файла получите объект `DiagramContent` из `Watermarker`. `DiagramContent` представляет внутреннюю иерархию страниц и фигур диаграммы. Эта модель предоставляет коллекции страниц и фигур, по которым можно итерировать, что упрощает поиск конкретных элементов, таких как изображения или текст.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### Как заменить изображения фигур в диаграмме?
+Пройдитесь по каждому `DiagramShape` на нужной странице, проверьте, содержит ли фигура изображение, и замените байты изображения на байты нового файла. `DiagramShape` — модель отдельной фигуры в диаграмме, а `DiagramWatermarkableImage` хранит данные изображения, которые можно применить к фигуре.
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### Как сохранить изменения и закрыть Watermarker?
+Когда все изменения завершены, вызовите `save` у `Watermarker`, чтобы записать обновлённую диаграмму в файл, затем вызовите `close` для освобождения нативных ресурсов. Это гарантирует освобождение файловых дескрипторов и предотвращает утечки памяти, особенно при обработке большого количества диаграмм в пакетной задаче.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+
+public class FeatureSaveAndCloseWatermarker {
+ public static void run(Watermarker watermarker) throws Exception {
+ String outputPath = "YOUR_OUTPUT_DIRECTORY/output.vsdx";
+ watermarker.save(outputPath);
+ watermarker.close();
+ }
+}
+```
+```
+
+## Добавление водяного знака к той же диаграмме (необязательно)
+
+Если вам также нужно брендировать диаграмму, вы можете добавить водяной знак до или после замены изображений:
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+
+## Распространённые проблемы и их устранение
+
+| Симптом | Вероятная причина | Решение |
+|---------|-------------------|---------|
+| Изображение не изменилось после выполнения кода | `DiagramShape.hasImage()` вернул false | Проверьте тип фигуры; некоторые векторные фигуры хранят изображения иначе. |
+| OutOfMemoryError при работе с большими файлами | Загрузка всей диаграммы сразу | Используйте `DiagramLoadOptions.setLoadMode(LoadMode.Stream)`, чтобы обрабатывать страницы последовательно. |
+| Водяной знак не виден | Водяной знак размещён позади существующего содержимого | Вызовите `watermarker.setWatermarkPosition(Position.Foreground)` перед сохранением. |
+
+## Часто задаваемые вопросы
+
+**Q: Можно ли заменять изображения в диаграммах, защищённых паролем?**
+A: Да. Передайте пароль в `DiagramLoadOptions` при создании `Watermarker`.
+
+**Q: Работает ли библиотека с файлами .drawio (XML)?**
+A: Абсолютно — GroupDocs.Watermark поддерживает формат Draw.io XML и рассматривает каждый узел как фигуру.
+
+**Q: Сколько диаграмм я могу обрабатывать параллельно?**
+A: Библиотека потокобезопасна для операций только чтения; для операций записи ограничьте параллелизм количеством ядер CPU, чтобы избежать конкуренции за файловые дескрипторы.
+
+**Q: Есть ли ограничение на размер изображения?**
+A: Поддерживаются изображения размером до 100 МБ; более крупные файлы следует предварительно уменьшить, чтобы снизить использование памяти.
+
+**Q: Какие варианты лицензирования доступны?**
+A: Вы можете начать с бесплатной 30‑дневной пробной версии; для продакшн‑использования требуется платная лицензия, которую можно получить в магазине GroupDocs.

+# Защита диаграмм интеллектуальной собственности с помощью GroupDocs.Watermark
+
+Защита диаграмм интеллектуальной собственности — критически важный шаг для любой организации, которая делится дизайнерскими активами, блок‑схемами или архитектурными чертежами. С GroupDocs.Watermark для Java вы можете программно загружать файлы диаграмм (например, `.vsdx`), обнаруживать экземпляры водяных знаков‑изображений, искать текстовые водяные знаки и безопасно удалять их без повреждения оригинального рисунка. Этот учебник проведёт вас через весь процесс — от настройки окружения до пакетной обработки больших библиотек диаграмм — чтобы вы могли встроить надёжную защиту ИС непосредственно в свои Java‑приложения.
+
+## Быстрые ответы
+- **Какая библиотека обрабатывает водяные знаки диаграмм?** GroupDocs.Watermark for Java.
+- **Могу ли я обнаруживать водяные знаки‑изображения, а также текст?** Да, API предоставляет `ImageDctHashSearchCriteria` для обнаружения изображений и `TextSearchCriteria` для текста.
+- **Нужна ли коммерческая лицензия для запуска кода?** Пробная лицензия работает для разработки; платная лицензия требуется для продакшн‑использования.
+- **Поддерживается ли пакетная обработка?** Абсолютно — цикл по папке и применение той же логики водяных знаков к каждому файлу.
+- **Останется ли оригинальная компоновка диаграммы неизменной после удаления?** Библиотека очищает только объекты водяных знаков, сохраняя все формы, соединители и форматирование.
+
+## Что такое диаграммы интеллектуальной собственности?
+Диаграммы интеллектуальной собственности — это визуальные представления — такие как блок‑схемы, UML‑модели, сетевые схемы или архитектурные чертежи, содержащие собственническую информацию, принадлежащую отдельному лицу или организации. Эти диаграммы часто передают конфиденциальные процессы, дизайны или стратегии, делая их ценными активами, требующими защиты от несанкционированного копирования, распространения или изменения. Рассматривая их как интеллектуальную собственность, вы можете применять юридические и технические меры защиты, включая водяные знаки, чтобы контролировать их использование и распространение.
+
+## Почему использовать GroupDocs.Watermark для Java?
+GroupDocs.Watermark поддерживает **50+ форматов ввода и вывода** (включая `.vsdx`, `.vdx`, `.vsx`) и может обрабатывать многосотенные диаграммы без загрузки всего файла в память, снижая потребление ОЗУ до **70 %** по сравнению с наивными подходами потоковой обработки файлов. API также предлагает встроенное сравнение изображений без OCR, обеспечивая надёжные операции `detect image watermark` менее чем за **200 ms** на диаграмму на типичном сервере с частотой 2,5 ГГц.
+
+## Требования
+1. **Java Development Kit (JDK) 8+** — код использует стандартные API Java 8.

+
+## Как инициализировать Watermarker?
+Создание экземпляра `Watermarker` — первый шаг в любой работе с водяными знаками. Класс `Watermarker` загружает файл диаграммы в память и предоставляет методы для поиска, добавления и удаления водяных знаков. Передавая путь к диаграмме и опциональные `DiagramLoadOptions`, вы получаете объект, который служит центральной точкой для всех последующих операций, обеспечивая согласованную обработку документа на протяжении всего процесса.
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## Как загрузить документ диаграммы?
+Загрузка диаграммы с помощью `DiagramLoadOptions` даёт тонкую настройку того, как файл будет парситься. `DiagramLoadOptions` позволяет указать, загружать ли только видимые страницы, сохранять ли скрытые слои и как обрабатывать встроенные шрифты. Настройка этих параметров может значительно повысить производительность при работе с большими диаграммами и гарантирует, что обрабатываются только необходимые части файла, уменьшая использование памяти и ускоряя обнаружение водяных знаков.
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## Как обнаружить изображение‑водяной знак в диаграмме?
+Обнаружение изображений‑водяных знаков опирается на класс `ImageDctHashSearchCriteria`, который вычисляет перцептивный хеш эталонного изображения и сравнивает его со всеми встроенными изображениями в диаграмме. Этот метод быстрый и устойчив к небольшим визуальным изменениям, позволяя находить логотипы или другие графические водяные знаки даже при их изменении размера или небольших искажениях. Настраивая порог сходства, вы можете балансировать чувствительность обнаружения и количество ложных срабатываний.
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## Как искать текстовые водяные знаки?
+Поиск текстовых водяных знаков использует класс `TextSearchCriteria`. Этот класс сканирует все текстовые слои внутри диаграммы, включая те, что находятся внутри фигур, соединителей и групп, и возвращает любые совпадения, содержащие указанную строку или шаблон. Поиск по умолчанию нечувствителен к регистру и может быть уточнён с помощью регулярных выражений, позволяя находить водяные знаки, которые могут быть повернуты, частично скрыты или встроены в сложные структуры диаграмм.
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## Как удалить водяные знаки из диаграммы?
+Удаление водяных знаков выполняется вызовом метода `clear()` у каждого объекта `Watermark`, возвращённого операцией поиска. Метод `clear()` удаляет только визуальные элементы водяного знака, оставляя базовые объекты диаграммы — такие как формы, соединители и форматирование — нетронутыми. После очистки сохраняйте документ с помощью метода `save`, получая чистую версию диаграммы, сохраняющую оригинальную компоновку и функциональность.
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## Практические применения
+- **Enterprise software integration:** Встраивание проверки водяных знаков в системы управления документами для автоматического соблюдения политик ИС.
+- **Content management systems (CMS):** Сканирование загружаемых пользователями диаграмм на предмет неавторизованных логотипов перед публикацией.
+- **Legal document handling:** Обнаружение и удаление конфиденциальных водяных знаков при подготовке пакетов доказательств.
+
+## Распространённые подводные камни и устранение неполадок
+- **Missing license exception:** Убедитесь, что файл пробной или платной лицензии правильно указан через `License.setLicense("license_path")`.
+- **Large diagram slowdown:** Включите `loadOptions.setLoadHiddenLayers(false)` и рассмотрите обработку диаграмм в параллельных потоках.
+- **False‑positive image matches:** Отрегулируйте допуск DCT‑хеша с помощью `criteria.setSimilarityThreshold(0.85)`, чтобы уменьшить случайные совпадения.
+
+## Часто задаваемые вопросы
+
+**Q: Can I search for both text and image watermarks in a single call?**
+A: Yes, combine criteria with `OrSearchCriteria` (e.g., `new OrSearchCriteria(textCriteria, imageCriteria)`) to retrieve both types at once.
+
+**Q: Will removing watermarks corrupt the diagram layout?**
+A: No. The library isolates watermark objects, so shapes, connectors, and formatting remain unchanged after `clear()`.
+
+**Q: Which diagram formats are supported?**
+A: GroupDocs.Watermark handles `.vsdx`, `.vdx`, `.vsx`, and several older Visio formats, covering over **30** diagram types.

+# Cómo agregar marcas de agua a páginas de diagramas con texto en Java
+
+En los proyectos de software modernos, proteger los recursos visuales que compartes—especialmente los diagramas—se ha convertido en una prioridad principal. **Cómo agregar marcas de agua a diagramas** con texto en Java es un requisito común para las empresas que necesitan preservar la identidad de marca, evitar el uso no autorizado y rastrear la procedencia del documento. Este tutorial te guía a través de todo el proceso usando **GroupDocs.Watermark for Java**, desde la preparación del entorno hasta la verificación final, para que puedas asegurar tus diagramas con confianza.
+
+## Respuestas rápidas
+- **¿Qué biblioteca agrega marcas de agua?** GroupDocs.Watermark for Java.
+- **¿Qué versión de Java se requiere?** JDK 8 o superior.
+- **¿Necesito una licencia para pruebas?** Una licencia temporal gratuita funciona para evaluación.
+- **¿Puedo agregar marcas de agua a varias páginas a la vez?** Sí—aplica la marca de agua a todas las páginas en una sola llamada.
+- **¿El proceso es eficiente en memoria?** La API transmite páginas, por lo que incluso diagramas de 500 páginas permanecen bajo 200 MB de RAM.
+
+## Qué es la marca de agua en páginas de diagramas en Java
+Implica superponer programáticamente texto (o imágenes) semi‑transparentes sobre cada página de un archivo de diagrama—como Visio, SVG u otros formatos compatibles—usando una biblioteca Java. La marca de agua se convierte en parte del contenido visual, haciéndola visible en cualquier visor mientras se preservan los datos originales del diagrama.
+
+## Por qué usar GroupDocs.Watermark para Java
+GroupDocs.Watermark soporta **más de 50 formatos de entrada y salida**, procesa archivos de hasta **1 GB** sin cargar todo el documento en memoria, y ofrece **OCR incorporado** para detectar marcas de agua existentes. Estas capacidades cuantificadas garantizan una protección rápida y fiable para repositorios de diagramas a gran escala, mientras que su API simplifica la integración en aplicaciones Java.
+
+## Requisitos previos
+- **Java Development Kit (JDK)** 8 o superior instalado en tu máquina.
+- Un IDE como **IntelliJ IDEA** o **Eclipse** para editar y ejecutar código Java.
+- Familiaridad básica con Maven para la gestión de dependencias.
+
+### Bibliotecas y dependencias requeridas
+Usaremos GroupDocs.Watermark for Java, que puedes añadir a tu proyecto Maven:
+
+```xml
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Si prefieres una configuración manual, descarga los binarios desde la página oficial de lanzamientos [Versiones de GroupDocs.Watermark para Java](https://releases.groupdocs.com/watermark/java/) y añádelos al classpath de tu proyecto.
+
+### Obtención de licencia
+Comienza con una prueba gratuita obteniendo una licencia temporal de [GroupDocs.Trial Licensing](https://purchase.groupdocs.com/temporary-license/). Para uso en producción, compra una licencia completa y coloca el archivo `license.json` donde tu aplicación pueda leerlo:
+
+```java
+// Load the temporary or purchased license – keep unchanged
+```java
+License license = new License();
+license.setLicense("path/to/license/file");
+```
+```
+
+## Guía de implementación
+A continuación se muestra una guía paso a paso que indica exactamente cómo incrustar una marca de agua de texto en cada página de un diagrama.
+
+### ¿Cómo agrego una marca de agua de texto a una página de diagrama?
+Carga el diagrama, crea un objeto `TextWatermark`, aplícalo a las páginas deseadas y, finalmente, guarda la salida. Este flujo de extremo a extremo requiere solo cuatro llamadas concisas a la API y se ejecuta en menos de un segundo para archivos típicos de 10 páginas, mientras permite personalizar la fuente, el color, la opacidad y la rotación.
+
+#### Paso 1: carga tu diagrama
+DiagramLoadOptions indica a la biblioteca cómo leer archivos de diagramas, como manejar contraseñas u opciones de formato específicas. Primero, instancia un `Watermarker` con `DiagramLoadOptions`. Este objeto representa el diagrama fuente en memoria.
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### Paso 2: inicializa la marca de agua de texto
+`TextWatermark` define el texto visible, la fuente, el color y la rotación. También puedes establecer la opacidad para que la marca de agua sea sutil.
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### Paso 3: agrega la marca de agua a las páginas del diagrama
+DiagramShapeWatermarkOptions configura cómo se aplica una marca de agua a las formas del diagrama. DiagramWatermarkPlacementType especifica si la marca de agua aparece en primer plano o en segundo plano. Aplica la marca de agua a todas las páginas de fondo (o a un rango de páginas personalizado). La API transmite cada página, por lo que el uso de memoria se mantiene bajo incluso para archivos grandes.
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### Paso 4: guarda y cierra
+Guarda el diagrama con marca de agua en un nuevo archivo y libera los recursos.
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### Problemas comunes y soluciones
+- **Problemas con rutas de archivo:** Usa rutas absolutas o verifica que el directorio de trabajo coincida con la ubicación de tus archivos de diagrama.
+- **Incompatibilidades de versión:** Las versiones de GroupDocs.Watermark están vinculadas a versiones específicas de JDK; asegúrate de usar una compilación compatible con JDK 8‑17.
+- **Cuellos de botella de rendimiento:** Para procesamiento por lotes, reutiliza una única instancia de `Watermarker` y llama a `close()` solo después de que el lote finalice.
+
+## Aplicaciones prácticas
+Las marcas de agua de texto son útiles en muchos escenarios del mundo real:
+
+1. **Seguridad de documentos** – Impide que los competidores reutilicen diagramas propietarios.
+2. **Refuerzo de marca** – Inserta el nombre o eslogan de la empresa directamente en cada página.
+3. **Seguimiento de colaboración** – Añade las iniciales del usuario o marcas de tiempo para indicar quién editó un diagrama.
+
+## Consideraciones de rendimiento
+- **Gestión de memoria:** La biblioteca procesa las páginas de forma perezosa; siempre invoca `watermarker.close()` para liberar recursos nativos.
+- **Tamaño de la marca de agua:** Fuentes más grandes aumentan el tiempo de procesamiento linealmente; una fuente de 12 pt es un buen equilibrio entre legibilidad y velocidad.
+- **Pruebas por lotes:** Ejecuta la rutina de marcas de agua en una muestra representativa antes de escalar a miles de archivos.
+
+## Conclusión
+Ahora tienes un método completo y listo para producción para **cómo agregar marcas de agua a páginas de diagramas** con texto en Java usando GroupDocs.Watermark. Esta capacidad no solo protege tus recursos visuales, sino que también refuerza la consistencia de la marca en todos los diagramas compartidos.
+
+### Próximos pasos
+- Explora marcas de agua de imagen para un branding visual adicional.
+- Combina marcas de agua de texto e imagen para protección multilayer.
+- Integra el flujo de marcas de agua en tu pipeline CI/CD para automatizar la seguridad de diagramas.
+
+## Preguntas frecuentes
+1. **¿Puedo usar GroupDocs.Watermark para otros formatos de archivo?**
+ Sí—se admiten más de 50 formatos, incluidos PDF, DOCX, PPTX y SVG.
+
+2. **¿Hay un límite de cuántas marcas de agua puedo agregar?**
+ No hay un límite estricto, pero agregar más de 10 por página puede afectar la velocidad de renderizado.
+
+3. **¿Cómo elimino una marca de agua de un diagrama?**
+ Usa la API `Watermarker.removeWatermarks()` para detectar y eliminar marcas de agua existentes.
+
+4. **¿Puedo dirigirme solo a páginas específicas?**
+ Absolutamente—configura `WatermarkOptions` con un rango de páginas o un predicado personalizado.
+
+5. **¿Qué debo hacer si la marca de agua no es visible?**
+ Verifica la opacidad, el contraste de color y la configuración de rotación; consulta la documentación de la API para solucionar problemas.
+
+### Preguntas y respuestas adicionales
+**P: ¿La biblioteca admite diagramas protegidos con contraseña?**
+R: Sí—pasa la contraseña a `DiagramLoadOptions` al cargar el archivo.
+
+**P: ¿Puedo ejecutar esto en un servidor sin interfaz gráfica?**
+R: La API es completamente del lado del servidor y no requiere componentes GUI.
+
+**P: ¿Qué versiones de Java son oficialmente compatibles?**
+R: Java 8 a Java 17 están probadas y documentadas.
+
+**P: ¿Cómo maneja GroupDocs.Watermark archivos grandes?**
+R: Transmite páginas, manteniendo el uso máximo de memoria bajo 200 MB incluso para diagramas de 1 GB.

+
+## ¿Qué es reemplazar imágenes de diagramas en Java?
+Reemplazar imágenes de diagramas en Java significa encontrar programáticamente formas que contienen gráficos bitmap dentro de un archivo de diagrama (como .vsdx, .drawio o .svg) y cambiar esas imágenes incrustadas por otras nuevas usando la API de GroupDocs.Watermark. Esto automatiza actualizaciones que de otro modo requerirían edición manual en un editor de diagramas.
+
+## ¿Por qué usar GroupDocs.Watermark para el reemplazo de imágenes de diagramas?
+GroupDocs.Watermark admite **más de 50 formatos de entrada y salida** – incluidos Visio, Draw.io y SVG – y puede procesar **archivos de hasta 500 MB** sin cargar todo el documento en memoria, lo que brinda una **reducción del 30 % en el uso de CPU** en comparación con enfoques ingenuos de flujo de archivos.
+
+## Requisitos previos
+- JDK 8 o superior instalado.
+- Un IDE (IntelliJ IDEA, Eclipse o VS Code) para desarrollo Java.
+- Maven (o la capacidad de agregar JARs manualmente).
+- Una licencia válida de GroupDocs.Watermark (prueba o permanente). Puedes obtener una licencia en [GroupDocs](https://purchase.groupdocs.com/temporary-license/).

+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11

+
+## Cómo reemplazar imágenes de diagramas en Java paso a paso
+
+### ¿Cómo inicializas el Watermarker para un archivo de diagrama?
+Watermarker es la clase principal que representa un documento y proporciona métodos para la manipulación de contenido. Para comenzar, crea un objeto `Watermarker` que cargue el archivo de diagrama en memoria. La clase `Watermarker` es el punto de entrada central de GroupDocs.Watermark, permitiéndote leer, modificar y guardar documentos. Usa `DiagramLoadOptions` para especificar configuraciones específicas del formato, como DPI o rango de páginas. `DiagramLoadOptions` configura cómo se carga un diagrama, p. ej., estableciendo DPI o modo de carga.
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### ¿Cómo puedes acceder al contenido del diagrama para localizar formas?
+Después de cargar el archivo, recupera un objeto `DiagramContent` del `Watermarker`. `DiagramContent` representa la jerarquía interna del diagrama de páginas y formas. Este modelo expone colecciones de páginas y formas que puedes iterar, facilitando la localización de elementos específicos como imágenes o texto.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### ¿Cómo reemplazas imágenes de forma en un diagrama?
+Recorre cada `DiagramShape` en la página deseada, verifica si la forma contiene una imagen y reemplaza los bytes de la imagen por los de un nuevo archivo. `DiagramShape` es el modelo de una forma individual en un diagrama, mientras que `DiagramWatermarkableImage` almacena datos de imagen que pueden aplicarse a una forma.
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### ¿Cómo guardas los cambios y cierras el Watermarker?
+Cuando todas las modificaciones estén completas, llama a `save` en el `Watermarker` para escribir el diagrama actualizado a un archivo, luego invoca `close` para liberar los recursos nativos. Esto asegura que los manejadores de archivo se liberen y previene fugas de memoria, especialmente al procesar muchos diagramas en un trabajo por lotes.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+
+public class FeatureSaveAndCloseWatermarker {
+ public static void run(Watermarker watermarker) throws Exception {
+ String outputPath = "YOUR_OUTPUT_DIRECTORY/output.vsdx";
+ watermarker.save(outputPath);
+ watermarker.close();
+ }
+}
+```
+```
+
+## Añadir una marca de agua al mismo diagrama (opcional)
+
+Si también necesitas marcar el diagrama, puedes añadir una marca de agua antes o después del reemplazo de la imagen:
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+
+## Problemas comunes y solución de problemas
+
+| Síntoma | Causa probable | Solución |
+|---------|----------------|----------|
+| No hay cambio de imagen después de ejecutar el código | `DiagramShape.hasImage()` devolvió false | Verifica el tipo de forma; algunas formas vectoriales almacenan imágenes de manera diferente. |
+| OutOfMemoryError en archivos grandes | Cargar todo el diagrama de una vez | Usa `DiagramLoadOptions.setLoadMode(LoadMode.Stream)` para procesar las páginas secuencialmente. |
+| Marca de agua no visible | Marca de agua colocada detrás del contenido existente | Llama a `watermarker.setWatermarkPosition(Position.Foreground)` antes de guardar. |
+
+## Preguntas frecuentes
+
+**Q: ¿Puedo reemplazar imágenes en diagramas protegidos con contraseña?**
+A: Sí. Pasa la contraseña a `DiagramLoadOptions` al crear el `Watermarker`.
+
+**Q: ¿La biblioteca funciona con archivos .drawio (XML)?**
+A: Absolutamente – GroupDocs.Watermark admite el formato XML de Draw.io y trata cada nodo como una forma.
+
+**Q: ¿Cuántos diagramas puedo procesar en paralelo?**
+A: La biblioteca es segura para hilos en operaciones de solo lectura; para operaciones de escritura, limita la concurrencia al número de núcleos de CPU para evitar contención de manejadores de archivo.
+
+**Q: ¿Existe un límite de tamaño de imagen?**
+A: Se admiten imágenes de hasta 100 MB; los archivos más grandes deben redimensionarse previamente para mantener bajo el uso de memoria.
+
+**Q: ¿Qué opciones de licencia están disponibles?**
+A: Puedes comenzar con una prueba gratuita de 30 días; el uso en producción requiere una licencia de pago, que se puede obtener en la tienda de GroupDocs.

+# Proteger diagramas de propiedad intelectual con GroupDocs.Watermark
+
+Proteger diagramas de propiedad intelectual es un paso crítico para cualquier organización que comparta activos de diseño, diagramas de flujo o dibujos de arquitectura. Con GroupDocs.Watermark para Java puedes cargar programáticamente archivos de diagramas (como `.vsdx`), detectar instancias de marcas de agua de imagen, buscar marcas de agua de texto y eliminarlas de forma segura sin dañar el dibujo original. Este tutorial te guía a través de todo el proceso—desde la configuración del entorno hasta el procesamiento por lotes de grandes bibliotecas de diagramas—para que puedas integrar una protección robusta de PI directamente en tus aplicaciones Java.
+
+## Respuestas rápidas
+- **¿Qué biblioteca maneja las marcas de agua en diagramas?** GroupDocs.Watermark for Java.
+- **¿Puedo detectar marcas de agua de imagen así como de texto?** Sí, la API proporciona `ImageDctHashSearchCriteria` para detección de imágenes y `TextSearchCriteria` para texto.
+- **¿Necesito una licencia comercial para ejecutar el código?** Una licencia de prueba funciona para desarrollo; se requiere una licencia paga para producción.
+- **¿Se admite el procesamiento por lotes?** Absolutamente—recorre una carpeta y aplica la misma lógica de marcas de agua a cada archivo.
+- **¿El diseño original del diagrama permanecerá intacto después de la eliminación?** La biblioteca elimina solo los objetos de marca de agua, preservando todas las formas, conectores y formato.
+
+## ¿Qué son los diagramas de propiedad intelectual?
+Los diagramas de propiedad intelectual son representaciones visuales—como diagramas de flujo, modelos UML, esquemas de red o dibujos arquitectónicos—que contienen información propietaria de una persona u organización. Estos diagramas a menudo transmiten procesos, diseños o estrategias confidenciales, convirtiéndolos en activos valiosos que requieren protección contra copias, distribución o alteraciones no autorizadas. Al tratarlos como propiedad intelectual, puedes aplicar salvaguardas legales y técnicas, incluido el marcado de agua, para mantener el control sobre su uso y difusión.
+
+## ¿Por qué usar GroupDocs.Watermark para Java?
+GroupDocs.Watermark admite **más de 50 formatos de entrada y salida** (incluidos `.vsdx`, `.vdx`, `.vsx`) y puede procesar diagramas de cientos de páginas sin cargar todo el archivo en memoria, reduciendo el consumo de RAM hasta en **un 70 %** comparado con enfoques ingenuos de flujo de archivos. La API también ofrece comparación de hash de imagen sin OCR integrada, lo que permite operaciones fiables de `detect image watermark` en menos de **200 ms** por diagrama en un servidor típico de 2.5 GHz.
+

+
+## ¿Cómo inicializar el Watermarker?
+Crear una instancia de `Watermarker` es el primer paso en cualquier flujo de trabajo de marcas de agua. La clase `Watermarker` carga un archivo de diagrama en memoria y proporciona métodos para buscar, agregar y eliminar marcas de agua. Al pasar la ruta del diagrama y opcionalmente `DiagramLoadOptions`, obtienes un objeto que sirve como punto central para todas las operaciones posteriores, garantizando un manejo coherente del documento a lo largo del proceso.
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## ¿Cómo cargar un documento de diagrama?
+Cargar un diagrama con `DiagramLoadOptions` te brinda un control granular sobre cómo se analiza el archivo. `DiagramLoadOptions` permite especificar si se cargan solo las páginas visibles, si se preservan capas ocultas y cómo manejar fuentes incrustadas. Ajustar estas opciones puede mejorar drásticamente el rendimiento para diagramas grandes y asegura que solo se procesen las partes necesarias del archivo, reduciendo el uso de memoria y acelerando la detección de marcas de agua.
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## ¿Cómo detectar una marca de agua de imagen en un diagrama?
+Detectar marcas de agua de imagen se basa en la clase `ImageDctHashSearchCriteria`, que calcula un hash perceptual de una imagen de referencia y lo compara con cada imagen incrustada en el diagrama. Este método es rápido y tolerante a pequeñas variaciones visuales, lo que permite localizar logotipos u otras marcas gráficas incluso si han sido redimensionadas o ligeramente alteradas. Configurando el umbral de similitud, puedes equilibrar la sensibilidad de detección contra coincidencias falsos positivos.
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## ¿Cómo buscar marcas de agua de texto?
+Buscar marcas de agua de texto utiliza la clase `TextSearchCriteria`. Esta clase escanea todas las capas textuales dentro del diagrama, incluidas las que están dentro de formas, conectores y agrupaciones, y devuelve cualquier coincidencia que contenga la cadena o patrón especificado. La búsqueda no distingue entre mayúsculas y minúsculas por defecto y puede refinarse con expresiones regulares, lo que permite localizar marcas de agua que puedan estar rotadas, parcialmente ocultas o incrustadas en estructuras de diagrama complejas.
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## ¿Cómo eliminar marcas de agua de un diagrama?
+Eliminar marcas de agua se realiza invocando el método `clear()` en cada objeto `Watermark` devuelto por una operación de búsqueda. El método `clear()` elimina solo los elementos visuales de la marca de agua mientras deja intactos los objetos subyacentes del diagrama—como formas, conectores y formato. Después de limpiar, guardas el documento usando el método `save`, produciendo una versión limpia del diagrama que conserva su diseño y funcionalidad originales.
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## Aplicaciones prácticas
+- **Integración de software empresarial:** Incrusta la validación de marcas de agua en sistemas de gestión de documentos para aplicar políticas de PI automáticamente.
+- **Sistemas de gestión de contenido (CMS):** Escanea diagramas subidos por usuarios en busca de logotipos no autorizados antes de publicar.
+- **Gestión de documentos legales:** Detecta y elimina marcas de agua confidenciales al preparar paquetes de evidencia.
+
+## Problemas comunes y solución de errores
+- **Excepción de licencia faltante:** Asegúrate de que el archivo de licencia de prueba o paga esté referenciado correctamente mediante `License.setLicense("license_path")`.
+- **Ralentización con diagramas grandes:** Habilita `loadOptions.setLoadHiddenLayers(false)` y considera procesar diagramas en flujos paralelos.
+- **Coincidencias de imagen falsos positivos:** Ajusta la tolerancia del hash DCT con `criteria.setSimilarityThreshold(0.85)` para reducir coincidencias accidentales.
+
+## Preguntas frecuentes
+
+**Q: ¿Puedo buscar tanto marcas de agua de texto como de imagen en una sola llamada?**
+A: Sí, combina criterios con `OrSearchCriteria` (p. ej., `new OrSearchCriteria(textCriteria, imageCriteria)`) para obtener ambos tipos a la vez.
+
+**Q: ¿Eliminar marcas de agua dañará el diseño del diagrama?**
+A: No. La biblioteca aísla los objetos de marca de agua, por lo que las formas, conectores y el formato permanecen sin cambios después de `clear()`.
+
+**Q: ¿Qué formatos de diagramas son compatibles?**
+A: GroupDocs.Watermark maneja `.vsdx`, `.vdx`, `.vsx` y varios formatos antiguos de Visio, cubriendo más de **30** tipos de diagramas.
+
+**Q: ¿Cómo proceso miles de diagramas de manera eficiente?**
+A: Usa `ExecutorService` de Java para ejecutar la detección/eliminación de marcas de agua en lotes paralelos y reutiliza un solo objeto de configuración `Watermarker` para reducir la sobrecarga.
+
+**Q: ¿Es posible integrar esto en una canalización CI/CD?**
+A: Absolutamente. Añade los fragmentos de Java a tus scripts de compilación (Maven/Gradle) y ejecútalos como paso de verificación previo al despliegue para asegurar que no haya marcas de agua prohibidas.

+# Hur man vattenstämplar diagramssidor med text i Java
+
+I moderna mjukvaruprojekt har skyddet av de visuella tillgångar du delar—särskilt diagram—blivit en högsta prioritet. **Hur man vattenstämplar diagram**-sidor med text i Java är ett vanligt krav för företag som behöver bevara varumärkesidentitet, förhindra obehörig återanvändning och spåra dokumentets ursprung. Denna handledning guidar dig genom hela processen med **GroupDocs.Watermark for Java**, från miljöförberedelse till slutlig verifiering, så att du tryggt kan säkra dina diagram.
+
+## Snabba svar
+- **Vilket bibliotek lägger till vattenstämplar?** GroupDocs.Watermark for Java.
+- **Vilken Java-version krävs?** JDK 8 eller nyare.
+- **Behöver jag en licens för testning?** En gratis tillfällig licens fungerar för utvärdering.
+- **Kan jag vattenstämpla flera sidor samtidigt?** Ja—applicera vattenstämpeln på alla sidor i ett enda anrop.
+- **Är processen minnes‑effektiv?** API:et strömmar sidor, så även 500‑sidiga diagram håller sig under 200 MB RAM.
+
+## Vad är vattenstämpling av diagramssidor i Java?
+Det innebär att programatiskt överlagra halvgenomskinlig text (eller bilder) på varje sida i en diagramfil—såsom Visio, SVG eller andra stödda format—med ett Java‑bibliotek. Vattenstämpeln blir en del av det visuella innehållet, synlig i alla visare samtidigt som den bevarar den ursprungliga diagramdata.
+
+## Varför använda GroupDocs.Watermark för Java?
+GroupDocs.Watermark stödjer **50+ in- och utdataformat**, bearbetar filer upp till **1 GB** utan att ladda hela dokumentet i minnet, och erbjuder **inbyggd OCR** för att upptäcka befintliga vattenstämplar. Dessa kvantifierade funktioner säkerställer snabb, pålitlig skydd för storskaliga diagramarkiv, samtidigt som dess API förenklar integration i Java‑applikationer.
+
+## Förutsättningar
+- **Java Development Kit (JDK)** 8 eller högre installerat på din maskin.
+- En IDE såsom **IntelliJ IDEA** eller **Eclipse** för att redigera och köra Java‑kod.
+- Grundläggande kunskap om Maven för beroendehantering.
+
+### Nödvändiga bibliotek och beroenden
+Vi kommer att använda GroupDocs.Watermark för Java, som du kan lägga till i ditt Maven‑projekt:
+
+```xml
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Om du föredrar manuell installation, ladda ner binärerna från den officiella releasesidan [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/) och lägg till dem i ditt projekts klassväg.
+
+### Licensinnehav
+Börja med en gratis provperiod genom att skaffa en tillfällig licens från [GroupDocs.Trial Licensing](https://purchase.groupdocs.com/temporary-license/). För produktionsbruk, köp en full licens och placera `license.json`‑filen där din applikation kan läsa den:
+
+```java
+// Load the temporary or purchased license – keep unchanged
+```java
+License license = new License();
+license.setLicense("path/to/license/file");
+```
+```
+
+## Implementeringsguide
+Nedan följer en steg‑för‑steg‑genomgång som visar exakt hur du bäddar in en textvattenstämpel i varje sida av ett diagram.
+
+### Hur lägger jag till en textvattenstämpel på en diagramssida?
+Läs in diagrammet, skapa ett `TextWatermark`‑objekt, applicera det på önskade sidor och spara slutligen resultatet. Detta end‑to‑end‑flöde kräver bara fyra koncisa API‑anrop och körs på under en sekund för typiska 10‑sidiga filer, samtidigt som det möjliggör anpassning av teckensnitt, färg, opacitet och rotation.
+
+#### Steg 1: läs in ditt diagram
+DiagramLoadOptions instruerar biblioteket hur diagramfiler ska läsas, t.ex. hantering av lösenord eller specifika formatalternativ. Först, skapa en `Watermarker` med `DiagramLoadOptions`. Detta objekt representerar källdiagrammet i minnet.
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### Steg 2: initiera textvattenstämpeln
+`TextWatermark` definierar den synliga texten, teckensnitt, färg och rotation. Du kan också ställa in opacitet för att göra vattenstämpeln subtil.
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### Steg 3: lägg till vattenstämpel på diagramssidor
+DiagramShapeWatermarkOptions konfigurerar hur en vattenstämpel appliceras på diagramformer. DiagramWatermarkPlacementType specificerar om vattenstämpeln visas i förgrunden eller bakgrunden. Applicera vattenstämpeln på alla bakgrundssidor (eller ett anpassat sidintervall). API:et strömmar varje sida, så minnesanvändningen förblir låg även för stora filer.
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### Steg 4: spara och stäng
+Spara det vattenstämplade diagrammet till en ny fil och frigör resurser.
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### Vanliga problem och lösningar
+- **Problem med filsökvägar:** Använd absoluta sökvägar eller verifiera att arbetskatalogen matchar platsen för dina diagramfiler.
+- **Versionskonflikter:** GroupDocs.Watermark‑releaser är knutna till specifika JDK‑versioner; säkerställ att du använder en kompatibel JDK 8‑17‑byggnad.
+- **Prestandaflaskhalsar:** För batch‑bearbetning, återanvänd en enda `Watermarker`‑instans och anropa `close()` först när batchen är klar.
+
+## Praktiska tillämpningar
+Textvattenstämplar är användbara i många verkliga scenarier:
+
+1. **Dokumentsäkerhet** – Förhindra konkurrenter från att återanvända proprietära diagram.
+2. **Varumärkesförstärkning** – Inkludera företagsnamn eller slogan direkt på varje sida.
+3. **Samarbetsspårning** – Lägg till användarinitialer eller tidsstämplar för att ange vem som redigerade ett diagram.
+
+## Prestandaöverväganden
+- **Minneshantering:** Biblioteket bearbetar sidor lazily; anropa alltid `watermarker.close()` för att frigöra inhemska resurser.
+- **Vattenstämpelns storlek:** Större teckensnitt ökar bearbetningstiden linjärt; ett 12‑pt teckensnitt är en bra balans mellan läsbarhet och hastighet.
+- **Batch‑testning:** Kör vattenstämplingsrutinen på ett representativt urval innan du skalar upp till tusentals filer.
+
+## Slutsats
+Du har nu en komplett, produktionsklar metod för **hur man vattenstämplar diagram**-sidor med text i Java med hjälp av GroupDocs.Watermark. Denna funktion säkrar inte bara dina visuella tillgångar utan förstärker också varumärkeskonsistensen över alla delade diagram.
+
+### Nästa steg
+- Utforska bildvattenstämplar för ytterligare visuell varumärkesbyggnad.
+- Kombinera text- och bildvattenstämplar för flerskiktskydd.
+- Integrera vattenstämplingsflödet i din CI/CD‑pipeline för att automatisera diagramssäkerhet.
+
+## Vanliga frågor
+1. **Kan jag använda GroupDocs.Watermark för andra filformat?**
+ Ja—över 50 format, inklusive PDF, DOCX, PPTX och SVG, stöds.
+
+2. **Finns det någon gräns för hur många vattenstämplar jag kan lägga till?**
+ Ingen hård gräns, men att lägga till mer än 10 per sida kan påverka renderingshastigheten.
+
+3. **Hur tar jag bort en vattenstämpel från ett diagram?**
+ Använd `Watermarker.removeWatermarks()`‑API:et för att upptäcka och radera befintliga vattenstämplar.
+
+4. **Kan jag rikta in mig på specifika sidor endast?**
+ Absolut—konfigurera `WatermarkOptions` med ett sidintervall eller ett anpassat predikat.
+
+5. **Vad ska jag göra om vattenstämpeln inte syns?**
+ Verifiera opacitet, färgkontrast och rotationsinställningar; konsultera API‑dokumentationen för felsökning.
+
+### Ytterligare Q&A
+**Q: Stöder biblioteket lösenordsskyddade diagram?**
+A: Ja—skicka lösenordet till `DiagramLoadOptions` när filen läses in.
+
+**Q: Kan jag köra detta på en huvudlös server?**
+A: API:et är helt server‑side och kräver inga GUI‑komponenter.
+
+**Q: Vilka Java-versioner stöds officiellt?**
+A: Java 8 till Java 17 är testade och dokumenterade.
+
+**Q: Hur hanterar GroupDocs.Watermark stora filer?**
+A: Det strömmar sidor, vilket håller maxminnesanvändning under 200 MB även för 1 GB diagram.
+
+**Q: Finns det ett sätt att förhandsgranska vattenstämpeln innan sparning?**
+A: Använd `Watermarker.getResultImage()` för att generera en förhandsgransknings‑bitmap av någon sida.

+# Ersätt diagrambilder i Java med GroupDocs.Watermark
+
+Att uppdatera bilder i diagramfiler manuellt är tidskrävande och felbenäget. I den här handledningen lär du dig hur du **ersätter diagrambilder i Java** med bara några rader kod, och du får också se hur du **lägger till vattenstämpel i diagram** när det behövs. I slutet har du ett återanvändbart kodsnutt som du kan lägga in i vilket Java‑projekt som helst som arbetar med Visio, Draw.io eller andra stödda diagramformat.
+
+## Snabba svar
+- **Vilket bibliotek hanterar ersättning av diagrambilder?** GroupDocs.Watermark för Java.
+- **Hur många kodrader behövs för en grundläggande ersättning?** Endast tre rader efter att Watermarker har skapats.
+- **Kan jag lägga till en vattenstämpel samtidigt?** Ja – använd samma Watermarker‑instans med ett vattenstämpel‑objekt.
+- **Vilken Java‑version krävs?** JDK 8 eller högre.
+- **Behöver jag en licens för produktionsanvändning?** En giltig GroupDocs.Watermark‑licens krävs; en gratis provperiod finns tillgänglig.
+
+## Vad är ersättning av diagrambilder i Java?
+Att ersätta diagrambilder i Java innebär att programmässigt hitta former som innehåller bitmapgrafik i en diagramfil (såsom .vsdx, .drawio eller .svg) och byta ut de inbäddade bilderna mot nya med hjälp av GroupDocs.Watermark‑API:et. Detta automatiserar uppdateringar som annars skulle kräva manuell redigering i en diagramredigerare.
+
+## Varför använda GroupDocs.Watermark för ersättning av diagrambilder?
+GroupDocs.Watermark stöder **över 50 in‑ och utdataformat** – inklusive Visio, Draw.io och SVG – och kan bearbeta **filer upp till 500 MB** utan att ladda hela dokumentet i minnet, vilket ger dig en **30 % minskning av CPU‑användning** jämfört med naiva fil‑ström‑metoder.
+
+## Förutsättningar
+- JDK 8 eller nyare installerat.
+- En IDE (IntelliJ IDEA, Eclipse eller VS Code) för Java‑utveckling.
+- Maven (eller möjlighet att lägga till JAR‑filer manuellt).
+- En giltig GroupDocs.Watermark‑licens (prov eller permanent). Du kan skaffa en licens från [GroupDocs](https://purchase.groupdocs.com/temporary-license/).
+
+### Nödvändiga bibliotek, versioner och beroenden
+Lägg till GroupDocs.Watermark‑arkivet och beroendet i din `pom.xml`:
+
+```xml
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Om du föredrar manuell JAR‑hantering, ladda ner den senaste versionen från den officiella webbplatsen: [GroupDocs.Watermark för Java‑utgåvor](https://releases.groupdocs.com/watermark/java/).
+
+## Så ersätter du diagrambilder i Java steg för steg
+
+### Hur initierar du Watermarker för en diagramfil?
+Watermarker är huvudklassen som representerar ett dokument och tillhandahåller metoder för innehållsmanipulation. För att börja, skapa ett `Watermarker`‑objekt som laddar diagramfilen i minnet. `Watermarker`‑klassen är den centrala ingångspunkten för GroupDocs.Watermark, vilket låter dig läsa, ändra och spara dokument. Använd `DiagramLoadOptions` för att specificera format‑specifika inställningar såsom DPI eller sidintervall. `DiagramLoadOptions` konfigurerar hur ett diagram laddas, t.ex. DPI‑inställning eller laddningsläge.
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### Hur får du åtkomst till diagraminnehåll för att lokalisera former?
+Efter att filen har laddats, hämta ett `DiagramContent`‑objekt från `Watermarker`. `DiagramContent` representerar diagrammets interna hierarki av sidor och former. Denna modell exponerar samlingar av sidor och former som du kan iterera över, vilket gör det enkelt att hitta specifika element som bilder eller text.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### Hur ersätter du formbilder i ett diagram?
+Loopa igenom varje `DiagramShape` på den önskade sidan, kontrollera om formen innehåller en bild och ersätt bildbytarna med dem från en ny fil. `DiagramShape` är modellen för en enskild form i ett diagram, medan `DiagramWatermarkableImage` lagrar bilddata som kan appliceras på en form.
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### Hur sparar du ändringarna och stänger Watermarker?
+När alla ändringar är klara, anropa `save` på `Watermarker` för att skriva det uppdaterade diagrammet till en fil, och anropa sedan `close` för att frigöra inhemska resurser. Detta säkerställer att filhandtag frigörs och förhindrar minnesläckor, särskilt vid bearbetning av många diagram i ett batchjobb.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+
+public class FeatureSaveAndCloseWatermarker {
+ public static void run(Watermarker watermarker) throws Exception {
+ String outputPath = "YOUR_OUTPUT_DIRECTORY/output.vsdx";
+ watermarker.save(outputPath);
+ watermarker.close();
+ }
+}
+```
+```
+
+## Lägga till en vattenstämpel i samma diagram (valfritt)
+
+Om du också behöver märka diagrammet kan du lägga till en vattenstämpel före eller efter bildutbytet:
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+
+## Vanliga fallgropar och felsökning
+
+| Symptom | Trolig orsak | Åtgärd |
+|---------|--------------|-----|
+| Ingen bildändring efter att koden körts | `DiagramShape.hasImage()` returnerade falskt | Verifiera formtypen; vissa vektorformer lagrar bilder på annat sätt. |
+| OutOfMemoryError på stora filer | Laddar hela diagrammet på en gång | Använd `DiagramLoadOptions.setLoadMode(LoadMode.Stream)` för att bearbeta sidor sekventiellt. |
+| Vattenstämpel syns inte | Vattenstämpel placerad bakom befintligt innehåll | Anropa `watermarker.setWatermarkPosition(Position.Foreground)` innan du sparar. |
+
+## Vanliga frågor
+
+**Q: Kan jag ersätta bilder i lösenordsskyddade diagram?**
+A: Ja. Skicka lösenordet till `DiagramLoadOptions` när du skapar `Watermarker`.
+
+**Q: Fungerar biblioteket med .drawio (XML)-filer?**
+A: Absolut – GroupDocs.Watermark stöder Draw.io XML‑formatet och behandlar varje nod som en form.
+
+**Q: Hur många diagram kan jag bearbeta parallellt?**
+A: Biblioteket är trådsäkert för endast‑läsliga operationer; för skrivoperationer, begränsa samtidigheten till antalet CPU‑kärnor för att undvika konkurrens om filhandtag.
+
+**Q: Finns det någon gräns för bildstorlek?**
+A: Bilder upp till 100 MB stöds; större filer bör skalas ner i förväg för att hålla minnesanvändningen låg.
+
+**Q: Vilka licensalternativ finns tillgängliga?**
+A: Du kan börja med en gratis 30‑dagars provperiod; produktionsanvändning kräver en betald licens, som kan erhållas från GroupDocs‑butiken.

+# Skydda immateriella rättighetsdiagram med GroupDocs.Watermark
+
+Att skydda immateriella rättighetsdiagram är ett kritiskt steg för alla organisationer som delar designresurser, flödesscheman eller arkitekturritningar. Med GroupDocs.Watermark för Java kan du programatiskt läsa in diagramfiler (såsom `.vsdx`), upptäcka bildvattenstämpelinstanser, söka efter textvattenstämplar och säkert ta bort dem utan att förstöra den ursprungliga ritningen. Denna handledning guidar dig genom hela processen — från miljöinställning till batch‑bearbetning av stora diagrambibliotek — så att du kan integrera robust IP-skydd direkt i dina Java‑applikationer.
+
+## Snabba svar
+- **Vilket bibliotek hanterar diagramvattenstämplar?** GroupDocs.Watermark för Java.
+- **Kan jag upptäcka bildvattenstämplar såväl som text?** Ja, API:et tillhandahåller `ImageDctHashSearchCriteria` för bilddetektering och `TextSearchCriteria` för text.
+- **Behöver jag en kommersiell licens för att köra koden?** En provlicens fungerar för utveckling; en betald licens krävs för produktion.
+- **Stöds batch‑bearbetning?** Absolut — loopa över en mapp och tillämpa samma vattenstämpellogik på varje fil.
+- **Kommer det ursprungliga diagrammets layout att förbli intakt efter borttagning?** Biblioteket rensar endast vattenstämpelobjekt, vilket bevarar alla former, anslutningar och formatering.
+
+## Vad är immateriella rättighetsdiagram?
+Immateriella rättighetsdiagram är visuella representationer — såsom flödesscheman, UML‑modeller, nätverksscheman eller arkitekturritningar — som innehåller proprietär information som ägs av en individ eller organisation. Dessa diagram förmedlar ofta konfidentiella processer, designer eller strategier, vilket gör dem till värdefulla tillgångar som kräver skydd mot obehörig kopiering, distribution eller förändring. Genom att behandla dem som immateriella rättigheter kan du tillämpa juridiska och tekniska skyddsåtgärder, inklusive vattenstämpling, för att behålla kontrollen över deras användning och spridning.
+
+## Varför använda GroupDocs.Watermark för Java?
+GroupDocs.Watermark stöder **50+ in‑ och utdataformat** (inklusive `.vsdx`, `.vdx`, `.vsx`) och kan bearbeta diagram med flera hundra sidor utan att läsa in hela filen i minnet, vilket minskar RAM‑förbrukningen med upp till **70 %** jämfört med naiva fil‑ström‑metoder. API:et erbjuder också inbyggd OCR‑fri bild‑hash‑jämförelse, vilket möjliggör pålitliga `detect image watermark`‑operationer på under **200 ms** per diagram på en typisk 2,5 GHz‑server.
+
+## Förutsättningar
+Innan du börjar, se till att du har:
+
+1. **Java Development Kit (JDK) 8+** – koden använder standard‑Java 8‑API:er.
+2. **IDE** – IntelliJ IDEA, Eclipse eller någon annan editor du föredrar.
+3. **GroupDocs.Watermark för Java** – antingen via Maven eller en manuell JAR‑nedladdning.
+
+### Nödvändiga bibliotek och beroenden
+Du kan lägga till biblioteket via Maven eller ladda ner JAR‑filerna direkt.
+
+#### Maven‑inställning
+Lägg till repository‑ och beroende‑poster i din `pom.xml`‑fil:
+
+```xml

+- **Tillfällig licens:** Använd för korttids‑testning utan funktionsbegränsningar.
+- **Köp:** Krävs för produktionsdistributioner och för att låsa upp premiumformat.
+
+## Hur initierar man Watermarker?
+Att skapa en `Watermarker`‑instans är det första steget i alla vattenstämpel‑arbetsflöden. `Watermarker`‑klassen läser in en diagramfil i minnet och tillhandahåller metoder för att söka, lägga till och ta bort vattenstämplar. Genom att skicka diagrammets sökväg och valfria `DiagramLoadOptions` får du ett objekt som fungerar som central punkt för alla efterföljande operationer, vilket säkerställer konsekvent hantering av dokumentet genom hela processen.
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## Hur laddar man ett diagramdokument?
+Att ladda ett diagram med `DiagramLoadOptions` ger dig fin‑granulär kontroll över hur filen parsas. `DiagramLoadOptions` låter dig ange om endast synliga sidor ska laddas, om dolda lager ska bevaras och hur inbäddade teckensnitt ska hanteras. Justering av dessa alternativ kan dramatiskt förbättra prestandan för stora diagram och säkerställer att endast de nödvändiga delarna av filen bearbetas, vilket minskar minnesanvändningen och påskyndar vattenstämpeldetektion.
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## Hur upptäcker man bildvattenstämplar i ett diagram?
+Att upptäcka bildvattenstämplar bygger på klassen `ImageDctHashSearchCriteria`, som beräknar en perceptuell hash av en referensbild och jämför den mot varje inbäddad bild i diagrammet. Denna metod är snabb och tolerant mot mindre visuella variationer, vilket gör att du kan lokalisera logotyper eller andra grafiska vattenstämplar även om de har ändrats i storlek eller lätt modifierats. Genom att konfigurera likhetströskeln kan du balansera detekteringskänsligheten mot falskt‑positiva träffar.
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## Hur söker man efter textvattenstämplar?
+Sökning efter textvattenstämplar använder klassen `TextSearchCriteria`. Denna klass skannar alla textlager i diagrammet, inklusive de som finns i former, anslutningar och grupperingar, och returnerar alla träffar som innehåller den angivna strängen eller mönstret. Sökningen är skiftläges‑okänslig som standard och kan förfinas med reguljära uttryck, vilket gör att du kan lokalisera vattenstämplar som kan vara roterade, delvis dolda eller inbäddade i komplexa diagramstrukturer.
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## Hur tar man bort vattenstämplar från ett diagram?
+Att ta bort vattenstämplar utförs genom att anropa `clear()`‑metoden på varje `Watermark`‑objekt som returneras av en sökoperation. `clear()`‑metoden raderar endast de visuella vattenstämpel‑elementen medan de underliggande diagramobjekten — såsom former, anslutningar och formatering — förblir intakta. Efter rensning sparar du dokumentet med `save`‑metoden, vilket producerar en ren version av diagrammet som behåller sin ursprungliga layout och funktionalitet.
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## Praktiska tillämpningar
+- **Företagsprogramvaruintegration:** Bädda in vattenstämpelvalidering i dokumenthanteringssystem för att automatiskt upprätthålla IP‑policyer.
+- **Content Management Systems (CMS):** Skanna användaruppladdade diagram för obehöriga logotyper innan publicering.
+- **Hantering av juridiska dokument:** Upptäck och ta bort konfidentiella vattenstämplar när du förbereder bevispaket.
+
+## Vanliga fallgropar och felsökning
+- **Undantag för saknad licens:** Se till att prov‑ eller betald licensfil refereras korrekt via `License.setLicense("license_path")`.
+- **Långsamhet vid stora diagram:** Aktivera `loadOptions.setLoadHiddenLayers(false)` och överväg att bearbeta diagram i parallella strömmar.
+- **Falskt‑positiva bildträffar:** Justera DCT‑hash‑toleransen med `criteria.setSimilarityThreshold(0.85)` för att minska oavsiktliga träffar.
+
+## Vanliga frågor
+
+**Q: Kan jag söka efter både text- och bildvattenstämplar i ett enda anrop?**
+A: Ja, kombinera kriterier med `OrSearchCriteria` (t.ex. `new OrSearchCriteria(textCriteria, imageCriteria)`) för att hämta båda typerna samtidigt.
+
+**Q: Kommer borttagning av vattenstämplar att förstöra diagrammets layout?**
+A: Nej. Biblioteket isolerar vattenstämpelobjekt, så former, anslutningar och formatering förblir oförändrade efter `clear()`.
+
+**Q: Vilka diagramformat stöds?**
+A: GroupDocs.Watermark hanterar `.vsdx`, `.vdx`, `.vsx` och flera äldre Visio‑format, vilket täcker över **30** diagramtyper.
+
+**Q: Hur bearbetar jag tusentals diagram effektivt?**
+A: Använd Javas `ExecutorService` för att köra vattenstämpeldetektion/‑borttagning i parallella batcher, och återanvänd ett enda `Watermarker`‑konfigurationsobjekt för att minska overhead.
+
+**Q: Är det möjligt att integrera detta i en CI/CD‑pipeline?**
+A: Absolut. Lägg till Java‑snuttarna i dina byggskript (Maven/Gradle) och kör dem som ett för‑implementerings‑verifieringssteg för att säkerställa att inga förbjudna vattenstämplar finns.

+# วิธีใส่ลายน้ำในหน้าภาพแผนภาพด้วยข้อความใน Java
+
+ในโครงการซอฟต์แวร์สมัยใหม่ การปกป้องทรัพย์สินภาพที่คุณแชร์—โดยเฉพาะแผนภาพ—ได้กลายเป็นสิ่งสำคัญอันดับต้น ๆ **วิธีใส่ลายน้ำในหน้าภาพแผนภาพ** ด้วยข้อความใน Java เป็นความต้องการทั่วไปสำหรับบริษัทที่ต้องการรักษาอัตลักษณ์ของแบรนด์ ป้องกันการนำไปใช้โดยไม่ได้รับอนุญาต และติดตามแหล่งที่มาของเอกสาร นี้เป็นบทแนะนำที่พาคุณผ่านกระบวนการทั้งหมดโดยใช้ **GroupDocs.Watermark for Java** ตั้งแต่การเตรียมสภาพแวดล้อมจนถึงการตรวจสอบขั้นสุดท้าย เพื่อให้คุณมั่นใจในการปกป้องแผนภาพของคุณ
+
+## คำตอบอย่างรวดเร็ว
+- **ไลบรารีที่เพิ่มลายน้ำคืออะไร?** GroupDocs.Watermark for Java.
+- **ต้องการเวอร์ชัน Java ใด?** JDK 8 หรือใหม่กว่า.
+- **ต้องการไลเซนส์สำหรับการทดสอบหรือไม่?** ไลเซนส์ชั่วคราวฟรีทำงานสำหรับการประเมิน.
+- **สามารถใส่ลายน้ำหลายหน้าในครั้งเดียวได้หรือไม่?** ได้—ใส่ลายน้ำลงในทุกหน้าด้วยการเรียกครั้งเดียว.
+- **กระบวนการนี้มีประสิทธิภาพด้านหน่วยความจำหรือไม่?** API สตรีมหน้าต่าง ๆ ทำให้แม้แผนภาพ 500 หน้า ยังใช้หน่วยความจำน้อยกว่า 200 MB RAM.
+
+## การใส่ลายน้ำในหน้าภาพแผนภาพด้วย Java คืออะไร?
+มันหมายถึงการวางข้อความ (หรือภาพ) ที่มีความโปร่งแสงกึ่งหนึ่งลงบนแต่ละหน้าของไฟล์แผนภาพ—เช่น Visio, SVG หรือรูปแบบที่รองรับอื่น ๆ—โดยใช้ไลบรารี Java ลายน้ำจะกลายเป็นส่วนหนึ่งของเนื้อหาภาพ ทำให้มองเห็นได้ในโปรแกรมดูใด ๆ ขณะยังคงรักษาข้อมูลแผนภาพต้นฉบับไว้
+
+## ทำไมต้องใช้ GroupDocs.Watermark for Java?
+GroupDocs.Watermark รองรับ **รูปแบบเข้าและออกกว่า 50 แบบ**, ประมวลผลไฟล์ขนาดถึง **1 GB** โดยไม่ต้องโหลดเอกสารทั้งหมดเข้าสู่หน่วยความจำ, และมี **OCR ในตัว** สำหรับตรวจจับลายน้ำที่มีอยู่ ความสามารถเหล่านี้ทำให้การปกป้องแผนภาพขนาดใหญ่ทำได้อย่างรวดเร็วและเชื่อถือได้ พร้อมกับ API ที่ทำให้การรวมเข้ากับแอปพลิเคชัน Java ง่ายขึ้น
+
+## ข้อกำหนดเบื้องต้น
+- **Java Development Kit (JDK)** 8 หรือสูงกว่า ติดตั้งบนเครื่องของคุณ.
+- IDE เช่น **IntelliJ IDEA** หรือ **Eclipse** สำหรับแก้ไขและรันโค้ด Java.
+- ความคุ้นเคยพื้นฐานกับ Maven สำหรับการจัดการ dependencies.
+
+### ไลบรารีและ dependencies ที่จำเป็น
+เราจะใช้ GroupDocs.Watermark for Java ซึ่งคุณสามารถเพิ่มลงในโปรเจกต์ Maven ของคุณได้:
+
+```xml
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+หากคุณต้องการตั้งค่าด้วยตนเอง ให้ดาวน์โหลดไบนารีจากหน้ารีลีสอย่างเป็นทางการ [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/) แล้วเพิ่มลงใน classpath ของโปรเจกต์ของคุณ
+
+### การรับไลเซนส์
+เริ่มต้นด้วยการทดลองฟรีโดยรับไลเซนส์ชั่วคราวจาก [GroupDocs.Trial Licensing](https://purchase.groupdocs.com/temporary-license/). สำหรับการใช้งานจริง ให้ซื้อไลเซนส์เต็มและวางไฟล์ `license.json` ไว้ในตำแหน่งที่แอปพลิเคชันของคุณสามารถอ่านได้:
+
+```java
+// Load the temporary or purchased license – keep unchanged
+```java
+License license = new License();
+license.setLicense("path/to/license/file");
+```
+```
+
+## คู่มือการทำงาน
+ด้านล่างเป็นขั้นตอนแบบละเอียดที่แสดงวิธีฝังลายน้ำข้อความลงในทุกหน้าของแผนภาพอย่างแม่นยำ
+
+### ฉันจะเพิ่มลายน้ำข้อความลงในหน้าภาพแผนภาพได้อย่างไร?
+โหลดแผนภาพ, สร้างอ็อบเจ็กต์ `TextWatermark`, ใส่ลงในหน้าที่ต้องการ, และสุดท้ายบันทึกผลลัพธ์ กระบวนการตั้งแต่ต้นจนจบนี้ต้องการเพียงสี่การเรียก API สั้น ๆ และทำงานภายในหนึ่งวินาทีสำหรับไฟล์ประมาณ 10 หน้า พร้อมให้คุณปรับแต่งฟอนต์, สี, ความโปร่งแสง, และการหมุน
+
+#### ขั้นตอน 1: โหลดแผนภาพของคุณ
+DiagramLoadOptions บอกไลบรารีว่าจะอ่านไฟล์แผนภาพอย่างไร เช่น การจัดการรหัสผ่านหรือออปชันรูปแบบเฉพาะ ก่อนอื่นให้สร้างอินสแตนซ์ของ `Watermarker` ด้วย `DiagramLoadOptions`. อ็อบเจ็กต์นี้เป็นตัวแทนของแผนภาพต้นฉบับในหน่วยความจำ
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### ขั้นตอน 2: เริ่มต้นลายน้ำข้อความ
+`TextWatermark` กำหนดข้อความที่มองเห็นได้, ฟอนต์, สี, และการหมุน คุณยังสามารถตั้งค่าความโปร่งแสงเพื่อทำให้ลายน้ำดูอ่อนโยน
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### ขั้นตอน 3: ใส่ลายน้ำลงในหน้าภาพแผนภาพ
+DiagramShapeWatermarkOptions กำหนดวิธีการใส่ลายน้ำลงในรูปทรงของแผนภาพ. DiagramWatermarkPlacementType ระบุว่าลายน้ำจะแสดงในระดับหน้าแรกหรือพื้นหลัง. ใส่ลายน้ำลงในทุกหน้าพื้นหลัง (หรือช่วงหน้าที่กำหนดเอง). API สตรีมแต่ละหน้า ทำให้การใช้หน่วยความจำต่ำแม้ไฟล์ขนาดใหญ่
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### ขั้นตอน 4: บันทึกและปิด
+บันทึกแผนภาพที่มีลายน้ำลงในไฟล์ใหม่และปล่อยทรัพยากร
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### ปัญหาทั่วไปและวิธีแก้
+- **ปัญหาเกี่ยวกับเส้นทางไฟล์:** ใช้เส้นทางแบบเต็มหรือยืนยันว่าไดเรกทอรีทำงานตรงกับตำแหน่งไฟล์แผนภาพของคุณ.
+- **ความไม่ตรงกันของเวอร์ชัน:** รุ่นของ GroupDocs.Watermark เชื่อมโยงกับ JDK เวอร์ชันเฉพาะ; ตรวจสอบว่าคุณใช้ JDK 8‑17 ที่เข้ากันได้.
+- **คอขวดด้านประสิทธิภาพ:** สำหรับการประมวลผลเป็นชุด, ใช้ `Watermarker` ตัวเดียวซ้ำและเรียก `close()` หลังจากการประมวลผลชุดเสร็จ.
+
+## การประยุกต์ใช้งานจริง
+ลายน้ำข้อความมีประโยชน์ในหลายสถานการณ์จริง:
+1. **ความปลอดภัยของเอกสาร** – ป้องกันคู่แข่งจากการนำแผนภาพที่เป็นทรัพย์สินของบริษัทไปใช้ใหม่.
+2. **การเสริมสร้างแบรนด์** – ฝังชื่อบริษัทหรือสโลแกนลงในทุกหน้าโดยตรง.
+3. **การติดตามการทำงานร่วมกัน** – เพิ่มอักษรย่อของผู้ใช้หรือเวลาที่ทำการแก้ไขเพื่อระบุว่าใครแก้ไขแผนภาพ.
+
+## ข้อควรพิจารณาด้านประสิทธิภาพ
+- **การจัดการหน่วยความจำ:** ไลบรารีประมวลผลหน้าตามความต้องการ; ควรเรียก `watermarker.close()` เสมอเพื่อปล่อยทรัพยากรเนทีฟ.
+- **ขนาดลายน้ำ:** ฟอนต์ขนาดใหญ่เพิ่มเวลาประมวลผลแบบเชิงเส้น; ฟอนต์ 12 pt เป็นสมดุลที่ดีระหว่างความอ่านง่ายและความเร็ว.
+- **การทดสอบแบบชุด:** รันขั้นตอนลายน้ำบนตัวอย่างที่เป็นตัวแทนก่อนขยายเป็นหลายพันไฟล์.
+
+## สรุป
+ตอนนี้คุณมีวิธีที่ครบถ้วนและพร้อมใช้งานในขั้นตอนการผลิตสำหรับ **วิธีใส่ลายน้ำในหน้าภาพแผนภาพ** ด้วยข้อความใน Java โดยใช้ GroupDocs.Watermark ความสามารถนี้ไม่เพียงปกป้องทรัพย์สินภาพของคุณ แต่ยังเสริมความสอดคล้องของแบรนด์ในทุกแผนภาพที่แชร์
+
+### ขั้นตอนต่อไป
+- สำรวจลายน้ำภาพสำหรับการสร้างแบรนด์ภาพเพิ่มเติม.
+- ผสมผสานลายน้ำข้อความและภาพเพื่อการปกป้องหลายชั้น.
+- ผสานกระบวนการลายน้ำเข้าสู่ pipeline CI/CD ของคุณเพื่ออัตโนมัติการรักษาความปลอดภัยของแผนภาพ.
+
+## คำถามที่พบบ่อย
+1. **ฉันสามารถใช้ GroupDocs.Watermark กับรูปแบบไฟล์อื่นได้หรือไม่?**
+ ใช่—รองรับมากกว่า 50 รูปแบบ รวมถึง PDF, DOCX, PPTX, และ SVG.
+
+2. **มีขีดจำกัดจำนวนลายน้ำที่ฉันสามารถเพิ่มได้หรือไม่?**
+ ไม่มีขีดจำกัดที่แน่นอน แต่การเพิ่มมากกว่า 10 ลายน้ำต่อหน้าอาจทำให้ความเร็วการเรนเดอร์ลดลง.
+
+3. **ฉันจะลบลายน้ำออกจากแผนภาพได้อย่างไร?**
+ ใช้ API `Watermarker.removeWatermarks()` เพื่อค้นหาและลบลายน้ำที่มีอยู่.
+
+4. **ฉันสามารถกำหนดเป้าหมายเฉพาะบางหน้าได้หรือไม่?**
+ แน่นอน—กำหนด `WatermarkOptions` ด้วยช่วงหน้า หรือพรีดิเกตแบบกำหนดเอง.
+
+5. **ควรทำอย่างไรหากลายน้ำไม่ปรากฏ?**
+ ตรวจสอบค่าความโปร่งแสง, ความแตกต่างของสี, และการตั้งค่าการหมุน; ดูเอกสาร API เพื่อแก้ปัญหา.
+
+### คำถามเพิ่มเติม
+**ถาม: ไลบรารีรองรับแผนภาพที่มีการป้องกันด้วยรหัสผ่านหรือไม่?**
+**ตอบ:** ใช่—ส่งรหัสผ่านไปยัง `DiagramLoadOptions` เมื่อโหลดไฟล์.
+
+**ถาม: ฉันสามารถรันนี้บนเซิร์ฟเวอร์แบบไม่มีหน้าจอ (headless) ได้หรือไม่?**
+**ตอบ:** API ทำงานทั้งหมดบนเซิร์ฟเวอร์และไม่ต้องการส่วนประกอบ GUI.
+
+**ถาม: เวอร์ชัน Java ใดที่รองรับอย่างเป็นทางการ?**
+**ตอบ:** Java 8 ถึง Java 17 ได้รับการทดสอบและบันทึกไว้.
+
+**ถาม: GroupDocs.Watermark จัดการไฟล์ขนาดใหญ่อย่างไร?**
+**ตอบ:** มันสตรีมหน้าต่าง ๆ ทำให้การใช้หน่วยความจำสูงสุดต่ำกว่า 200 MB แม้สำหรับแผนภาพขนาด 1 GB.
+
+**ถาม: มีวิธีดูตัวอย่างลายน้ำก่อนบันทึกหรือไม่?**
+**ตอบ:** ใช้ `Watermarker.getResultImage()` เพื่อสร้างภาพพรีวิวของหน้าใดหน้าหนึ่ง.

+# แทนที่ภาพแผนภาพใน Java ด้วย GroupDocs.Watermark
+
+การอัปเดตภาพภายในไฟล์แผนภาพด้วยตนเองใช้เวลานานและเสี่ยงต่อข้อผิดพลาด ในบทแนะนำนี้คุณจะได้เรียนรู้วิธี **แทนที่ภาพแผนภาพใน Java** ด้วยเพียงไม่กี่บรรทัดของโค้ด และคุณยังจะเห็นวิธี **เพิ่มลายน้ำให้แผนภาพ** เมื่อจำเป็น เมื่อเสร็จแล้วคุณจะมีโค้ดส่วนนำกลับมาใช้ใหม่ที่สามารถใส่ลงในโครงการ Java ใด ๆ ที่ทำงานกับ Visio, Draw.io หรือรูปแบบแผนภาพที่รองรับอื่น ๆ
+
+## คำตอบสั้น
+- **ไลบรารีที่จัดการการแทนที่ภาพแผนภาพคืออะไร?** GroupDocs.Watermark สำหรับ Java
+- **ต้องใช้กี่บรรทัดของโค้ดสำหรับการแทนที่พื้นฐาน?** เพียงสามบรรทัดหลังจากสร้าง Watermarker
+- **สามารถเพิ่มลายน้ำได้พร้อมกันหรือไม่?** ได้ – ใช้ Watermarker ตัวเดียวกันพร้อมอ็อบเจกต์ลายน้ำ
+- **ต้องใช้ Java เวอร์ชันใด?** JDK 8 หรือสูงกว่า
+- **ต้องมีลิขสิทธิ์สำหรับการใช้งานในผลิตภัณฑ์หรือไม่?** ต้องมีลิขสิทธิ์ GroupDocs.Watermark ที่ถูกต้อง; มีรุ่นทดลองฟรีให้ใช้
+
+## Replace diagram images java คืออะไร?
+การแทนที่ภาพแผนภาพใน Java หมายถึงการค้นหาและเปลี่ยนรูปทรงที่มีกราฟิกบิตแมพภายในไฟล์แผนภาพ (เช่น .vsdx, .drawio หรือ .svg) ด้วยภาพใหม่โดยใช้ GroupDocs.Watermark API วิธีนี้ทำให้การอัปเดตอัตโนมัติที่โดยปกติจะต้องแก้ไขด้วยมือในโปรแกรมแก้ไขแผนภาพ
+
+## ทำไมต้องใช้ GroupDocs.Watermark สำหรับการแทนที่ภาพแผนภาพ?
+GroupDocs.Watermark รองรับ **รูปแบบไฟล์เข้าและออกกว่า 50 รูปแบบ** – รวมถึง Visio, Draw.io และ SVG – และสามารถประมวลผล **ไฟล์ขนาดสูงสุดถึง 500 MB** โดยไม่ต้องโหลดเอกสารทั้งหมดเข้าสู่หน่วยความจำ ทำให้คุณได้รับ **การลดการใช้ CPU ลง 30 %** เมื่อเทียบกับวิธีการสตรีมไฟล์แบบธรรมดา
+
+## ข้อกำหนดเบื้องต้น
+- ติดตั้ง JDK 8 หรือใหม่กว่า
+- IDE (IntelliJ IDEA, Eclipse หรือ VS Code) สำหรับการพัฒนา Java
+- Maven (หรือความสามารถในการเพิ่ม JAR ด้วยตนเอง)
+- ลิขสิทธิ์ GroupDocs.Watermark ที่ถูกต้อง (รุ่นทดลองหรือถาวร) คุณสามารถรับลิขสิทธิ์ได้จาก [GroupDocs](https://purchase.groupdocs.com/temporary-license/)

+```
+
+หากคุณต้องการจัดการ JAR ด้วยตนเอง ให้ดาวน์โหลดเวอร์ชันล่าสุดจากเว็บไซต์อย่างเป็นทางการ: [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/)
+
+## วิธีแทนที่ภาพแผนภาพใน Java ทีละขั้นตอน
+
+### วิธีการเริ่มต้น Watermarker สำหรับไฟล์แผนภาพ
+Watermarker คือคลาสหลักที่แทนเอกสารและให้เมธอดสำหรับการจัดการเนื้อหา เพื่อเริ่มต้น ให้สร้างอ็อบเจกต์ `Watermarker` ที่โหลดไฟล์แผนภาพเข้าสู่หน่วยความจำ `Watermarker` เป็นจุดเริ่มต้นของ GroupDocs.Watermark ที่ให้คุณอ่าน, แก้ไข, และบันทึกเอกสาร ใช้ `DiagramLoadOptions` เพื่อระบุการตั้งค่าเฉพาะรูปแบบ เช่น DPI หรือช่วงหน้า `DiagramLoadOptions` กำหนดวิธีการโหลดแผนภาพ เช่น การตั้งค่า DPI หรือโหมดการโหลด
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### วิธีเข้าถึงเนื้อหาแผนภาพเพื่อค้นหารูปทรง
+หลังจากโหลดไฟล์แล้ว ให้ดึงอ็อบเจกต์ `DiagramContent` จาก `Watermarker` `DiagramContent` แสดงโครงสร้างภายในของแผนภาพที่ประกอบด้วยหน้าและรูปทรง โมเดลนี้ให้คอลเลกชันของหน้าและรูปทรงที่คุณสามารถวนลูปเพื่อค้นหาองค์ประกอบเฉพาะ เช่น ภาพหรือข้อความ
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### วิธีแทนที่ภาพรูปทรงในแผนภาพ
+วนลูปผ่านแต่ละ `DiagramShape` บนหน้าที่ต้องการ ตรวจสอบว่ารูปทรงนั้นมีภาพหรือไม่ และแทนที่ไบต์ของภาพด้วยไฟล์ใหม่ `DiagramShape` คือโมเดลของรูปทรงเดี่ยวในแผนภาพ ส่วน `DiagramWatermarkableImage` เก็บข้อมูลภาพที่สามารถนำไปใช้กับรูปทรงได้
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### วิธีบันทึกการเปลี่ยนแปลงและปิด Watermarker
+เมื่อทำการแก้ไขทั้งหมดเสร็จแล้ว ให้เรียก `save` บน `Watermarker` เพื่อเขียนแผนภาพที่อัปเดตลงไฟล์ แล้วเรียก `close` เพื่อปล่อยทรัพยากรเนทีฟ การทำเช่นนี้จะทำให้ตัวจัดการไฟล์ถูกปล่อยและป้องกันการรั่วของหน่วยความจำ โดยเฉพาะเมื่อประมวลผลแผนภาพจำนวนมากในงานแบตช์
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+
+public class FeatureSaveAndCloseWatermarker {
+ public static void run(Watermarker watermarker) throws Exception {
+ String outputPath = "YOUR_OUTPUT_DIRECTORY/output.vsdx";
+ watermarker.save(outputPath);
+ watermarker.close();
+ }
+}
+```
+```
+
+## การเพิ่มลายน้ำให้แผนภาพเดียวกัน (ไม่บังคับ)
+
+หากคุณต้องการทำแบรนด์ให้กับแผนภาพ คุณสามารถเพิ่มลายน้ำก่อนหรือหลังการแทนที่ภาพได้:
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+

+
+## คำถามที่พบบ่อย
+
+**ถาม: ฉันสามารถแทนที่ภาพในแผนภาพที่มีการป้องกันด้วยรหัสผ่านได้หรือไม่?**
+ตอบ: ได้. ส่งรหัสผ่านไปยัง `DiagramLoadOptions` เมื่อสร้าง `Watermarker`
+
+**ถาม: ไลบรารีรองรับไฟล์ .drawio (XML) หรือไม่?**
+ตอบ: รองรับอย่างเต็มที่ – GroupDocs.Watermark รองรับรูปแบบ XML ของ Draw.io และถือแต่ละโหนดเป็นรูปทรง
+
+**ถาม: สามารถประมวลผลแผนภาพพร้อมกันได้กี่รายการ?**
+ตอบ: ไลบรารีปลอดภัยต่อเธรดสำหรับการอ่านอย่างเดียว; สำหรับการเขียนควรจำกัดความพร้อมกันให้เท่ากับจำนวนคอร์ CPU เพื่อหลีกเลี่ยงการแย่งตัวจัดการไฟล์
+
+**ถาม: มีขีดจำกัดขนาดของภาพหรือไม่?**
+ตอบ: รองรับภาพขนาดสูงสุด 100 MB; ไฟล์ที่ใหญ่กว่านั้นควรปรับขนาดก่อนเพื่อรักษาการใช้หน่วยความจำให้ต่ำ
+
+**ถาม: ตัวเลือกการให้ลิขสิทธิ์มีอะไรบ้าง?**
+ตอบ: คุณสามารถเริ่มต้นด้วยรุ่นทดลองฟรี 30 วัน; การใช้งานในผลิตภัณฑ์ต้องมีลิขสิทธิ์แบบชำระเงิน ซึ่งสามารถซื้อได้จากร้านค้า GroupDocs

+# ปกป้องแผนภาพทรัพย์สินทางปัญญาด้วย GroupDocs.Watermark
+
+การปกป้องแผนภาพทรัพย์สินทางปัญญาเป็นขั้นตอนสำคัญสำหรับองค์กรใด ๆ ที่แชร์สินทรัพย์การออกแบบ, แผนผัง, หรือภาพวาดสถาปัตยกรรม. ด้วย GroupDocs.Watermark for Java คุณสามารถโหลดไฟล์แผนภาพโดยโปรแกรม (เช่น `.vsdx`), ตรวจจับลายน้ำรูปภาพ, ค้นหาลายน้ำข้อความ, และลบออกอย่างปลอดภัยโดยไม่ทำให้ภาพวาดต้นฉบับเสียหาย. บทแนะนำนี้จะพาคุณผ่านกระบวนการทั้งหมด—ตั้งแต่การตั้งค่าสภาพแวดล้อมจนถึงการประมวลผลแบบแบตช์ของไลบรารีแผนภาพขนาดใหญ่—เพื่อให้คุณฝังการปกป้อง IP ที่แข็งแกร่งโดยตรงในแอปพลิเคชัน Java ของคุณ.
+
+## คำตอบด่วน
+- **ไลบรารีใดจัดการกับลายน้ำในแผนภาพ?** GroupDocs.Watermark for Java.
+- **ฉันสามารถตรวจจับลายน้ำรูปภาพและข้อความได้หรือไม่?** ใช่, API มี `ImageDctHashSearchCriteria` สำหรับการตรวจจับรูปภาพและ `TextSearchCriteria` สำหรับข้อความ.
+- **ฉันต้องใช้ไลเซนส์เชิงพาณิชย์เพื่อรันโค้ดหรือไม่?** ไลเซนส์ทดลองใช้ได้สำหรับการพัฒนา; จำเป็นต้องมีไลเซนส์แบบชำระเงินสำหรับการใช้งานจริง.
+- **รองรับการประมวลผลแบบกลุ่มหรือไม่?** แน่นอน—วนลูปผ่านโฟลเดอร์และใช้ตรรกะลายน้ำเดียวกันกับแต่ละไฟล์.
+- **การลบลายน้ำจะทำให้โครงร่างแผนภาพต้นฉบับยังคงเหมือนเดิมหรือไม่?** ไลบรารีจะลบเฉพาะวัตถุลายน้ำเท่านั้น, รักษารูปร่าง, ตัวเชื่อมต่อ, และการจัดรูปแบบทั้งหมดไว้.
+
+## แผนภาพทรัพย์สินทางปัญญาคืออะไร
+แผนภาพทรัพย์สินทางปัญญาเป็นการแสดงภาพเชิงภาพ—เช่น แผนผัง, โมเดล UML, แผนผังเครือข่าย, หรือภาพวาดสถาปัตยกรรม—ที่มีข้อมูลเชิงลิขสิทธิ์เป็นของบุคคลหรือองค์กร. แผนภาพเหล่านี้มักสื่อสารกระบวนการ, การออกแบบ, หรือกลยุทธ์ที่เป็นความลับ, ทำให้เป็นสินทรัพย์ที่มีคุณค่าและต้องการการปกป้องจากการคัดลอก, แจกจ่าย, หรือการดัดแปลงโดยไม่ได้รับอนุญาต. การถือว่าเป็นทรัพย์สินทางปัญญาช่วยให้คุณใช้มาตรการทางกฎหมายและเทคนิค, รวมถึงการใส่ลายน้ำ, เพื่อควบคุมการใช้และการเผยแพร่ของมัน.
+
+## ทำไมต้องใช้ GroupDocs.Watermark สำหรับ Java
+GroupDocs.Watermark รองรับ **50+** รูปแบบการเข้าและออก (รวมถึง `.vsdx`, `.vdx`, `.vsx`) และสามารถประมวลผลแผนภาพหลายร้อยหน้าโดยไม่ต้องโหลดไฟล์ทั้งหมดเข้าสู่หน่วยความจำ, ลดการใช้ RAM ได้ถึง **70 %** เมื่อเทียบกับวิธีการสตรีมไฟล์แบบดั้งเดิม. API ยังมีการเปรียบเทียบแฮชรูปภาพแบบไม่มี OCR ในตัว, ทำให้การ `detect image watermark` ทำได้อย่างเชื่อถือได้ในเวลาไม่ถึง **200 ms** ต่อแผนภาพบนเซิร์ฟเวอร์ 2.5 GHz ปกติ.
+
+## ข้อกำหนดเบื้องต้น
+ก่อนเริ่ม, โปรดตรวจสอบว่าคุณมี:
+
+1. **Java Development Kit (JDK) 8+** – โค้ดใช้ API มาตรฐานของ Java 8.
+2. **IDE** – IntelliJ IDEA, Eclipse, หรือเครื่องมือแก้ไขใด ๆ ที่คุณต้องการ.
+3. **GroupDocs.Watermark for Java** – สามารถติดตั้งผ่าน Maven หรือดาวน์โหลด JAR ด้วยตนเอง.
+
+### ไลบรารีและการพึ่งพาที่จำเป็น
+คุณสามารถเพิ่มไลบรารีผ่าน Maven หรือดาวน์โหลด JAR โดยตรง.
+
+#### การตั้งค่า Maven
+เพิ่ม repository และรายการ dependency ลงในไฟล์ `pom.xml` ของคุณ:
+
+```xml

+- **Temporary license:** ใช้สำหรับการทดสอบระยะสั้นโดยไม่มีข้อจำกัดฟีเจอร์.
+- **Purchase:** จำเป็นสำหรับการใช้งานในสภาพแวดล้อมจริงและเพื่อเปิดใช้งานฟอร์แมตพรีเมี่ยม.
+
+## วิธีการเริ่มต้น Watermarker?
+การสร้างอินสแตนซ์ `Watermarker` เป็นขั้นตอนแรกในกระบวนการลายน้ำใด ๆ. คลาส `Watermarker` โหลดไฟล์แผนภาพเข้าสู่หน่วยความจำและให้เมธอดสำหรับการค้นหา, เพิ่ม, และลบลายน้ำ. โดยการส่งพาธของแผนภาพและ `DiagramLoadOptions` ทางเลือก, คุณจะได้อ็อบเจ็กต์ที่ทำหน้าที่เป็นจุดศูนย์กลางสำหรับการดำเนินการต่อไปทั้งหมด, ทำให้การจัดการเอกสารสอดคล้องกันตลอดกระบวนการ.
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## วิธีการโหลดเอกสารแผนภาพ?
+การโหลดแผนภาพด้วย `DiagramLoadOptions` ให้การควบคุมระดับละเอียดว่าฟाइलจะถูกพาร์สอย่างไร. `DiagramLoadOptions` ให้คุณระบุว่าจะโหลดเฉพาะหน้าที่มองเห็น, จะรักษาชั้นที่ซ่อนอยู่หรือไม่, และจะจัดการกับฟอนต์ที่ฝังอยู่อย่างไร. การปรับตัวเลือกเหล่านี้สามารถเพิ่มประสิทธิภาพอย่างมากสำหรับแผนภาพขนาดใหญ่และทำให้แน่ใจว่าเฉพาะส่วนที่จำเป็นของไฟล์เท่านั้นที่ถูกประมวลผล, ลดการใช้หน่วยความจำและเร่งความเร็วการตรวจจับลายน้ำ.
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## วิธีการตรวจจับลายน้ำรูปภาพในแผนภาพ?
+การตรวจจับลายน้ำรูปภาพอาศัยคลาส `ImageDctHashSearchCriteria`, ซึ่งคำนวณแฮชเชิงรับรู้ของภาพอ้างอิงและเปรียบเทียบกับภาพทุกภาพที่ฝังอยู่ในแผนภาพ. วิธีนี้เร็วและทนต่อการเปลี่ยนแปลงภาพเล็กน้อย, ทำให้คุณสามารถค้นหาโลโก้หรือกราฟิกลายน้ำอื่น ๆ แม้ว่าจะถูกปรับขนาดหรือเปลี่ยนแปลงเล็กน้อย. โดยการกำหนดค่าขีดจำกัดความคล้ายคลึง, คุณสามารถปรับสมดุลระหว่างความไวต่อการตรวจจับและการจับคู่เท็จ.
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## วิธีการค้นหาลายน้ำข้อความ?
+การค้นหาลายน้ำข้อความใช้คลาส `TextSearchCriteria`. คลาสนี้สแกนทุกชั้นข้อความภายในแผนภาพ, รวมถึงข้อความในรูปทรง, ตัวเชื่อมต่อ, และกลุ่ม, แล้วคืนค่าการจับคู่ที่มีสตริงหรือแพทเทิร์นที่ระบุ. การค้นหาเป็นแบบไม่แยกแยะตัวพิมพ์ใหญ่/เล็กโดยค่าเริ่มต้นและสามารถปรับให้ละเอียดด้วย regular expressions, ทำให้คุณสามารถค้นหาลายน้ำที่อาจถูกหมุน, ซ่อนบางส่วน, หรือฝังในโครงสร้างแผนภาพซับซ้อนได้.
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## วิธีการลบลายน้ำจากแผนภาพ?
+การลบลายน้ำทำโดยเรียกเมธอด `clear()` บนแต่ละอ็อบเจ็กต์ `Watermark` ที่ได้จากการค้นหา. เมธอด `clear()` จะลบเฉพาะองค์ประกอบลายน้ำที่มองเห็นได้เท่านั้น, ขณะที่วัตถุแผนภาพพื้นฐาน—เช่น รูปร่าง, ตัวเชื่อมต่อ, และการจัดรูปแบบ—ยังคงอยู่ครบถ้วน. หลังจากลบแล้ว, ให้บันทึกเอกสารด้วยเมธอด `save`, จะได้เวอร์ชันแผนภาพที่สะอาดและคงรูปแบบต้นฉบับไว้.
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## การประยุกต์ใช้งานจริง
+- **Enterprise software integration:** ฝังการตรวจสอบลายน้ำลงในระบบจัดการเอกสารเพื่อบังคับใช้นโยบาย IP อัตโนมัติ.
+- **Content management systems (CMS):** สแกนแผนภาพที่ผู้ใช้อัปโหลดเพื่อค้นหาโลโก้ที่ไม่ได้รับอนุญาตก่อนเผยแพร่.
+- **Legal document handling:** ตรวจจับและลบลายน้ำที่เป็นความลับเมื่อเตรียมชุดหลักฐาน.
+
+## ข้อผิดพลาดทั่วไปและการแก้ไขปัญหา
+- **Missing license exception:** ตรวจสอบให้แน่ใจว่าไฟล์ไลเซนส์ทดลองหรือแบบชำระเงินถูกอ้างอิงอย่างถูกต้องผ่าน `License.setLicense("license_path")`.
+- **Large diagram slowdown:** เปิดใช้งาน `loadOptions.setLoadHiddenLayers(false)` และพิจารณาประมวลผลแผนภาพใน parallel streams.
+- **False‑positive image matches:** ปรับค่าความทนทานของ DCT hash ด้วย `criteria.setSimilarityThreshold(0.85)` เพื่อลดการจับคู่เท็จ.
+
+## คำถามที่พบบ่อย
+
+**Q: ฉันสามารถค้นหาลายน้ำข้อความและรูปภาพในคำสั่งเดียวได้หรือไม่?**
+A: ใช่, ผสาน criteria ด้วย `OrSearchCriteria` (เช่น `new OrSearchCriteria(textCriteria, imageCriteria)`) เพื่อดึงข้อมูลทั้งสองประเภทพร้อมกัน.
+
+**Q: การลบลายน้ำจะทำให้โครงร่างแผนภาพเสียหายหรือไม่?**
+A: ไม่. ไลบรารีแยกวัตถุลายน้ำออก, ดังนั้นรูปทรง, ตัวเชื่อมต่อ, และการจัดรูปแบบจะคงเดิมหลังจาก `clear()`.
+
+**Q: แผนภาพรูปแบบใดบ้างที่รองรับ?**
+A: GroupDocs.Watermark รองรับ `.vsdx`, `.vdx`, `.vsx` และหลายรูปแบบ Visio เก่า, ครอบคลุมกว่า **30** ประเภทแผนภาพ.
+
+**Q: จะประมวลผลแผนภาพหลายพันไฟล์อย่างมีประสิทธิภาพได้อย่างไร?**
+A: ใช้ `ExecutorService` ของ Java เพื่อรันการตรวจจับ/ลบลายน้ำแบบแบตช์ขนาน, และใช้วัตถุการตั้งค่า `Watermarker` เพียงอันเดียวเพื่อ ลดค่าโอเวอร์เฮด.
+
+**Q: สามารถผสานเข้ากับ pipeline CI/CD ได้หรือไม่?**
+A: แน่นอน. เพิ่มสคริปต์ Java ลงในสคริปต์การสร้าง (Maven/Gradle) และเรียกใช้เป็นขั้นตอนตรวจสอบก่อนการปรับใช้ เพื่อให้แน่ใจว่าไม่มีลายน้ำที่ห้ามอยู่.

+Ücretsiz deneme için [GroupDocs.Trial Licensing](https://purchase.groupdocs.com/temporary-license/) adresinden geçici bir lisans alın. Üretim kullanımı için tam bir lisans satın alın ve `license.json` dosyasını uygulamanızın okuyabileceği bir konuma yerleştirin:
+
+```java
+// Load the temporary or purchased license – keep unchanged
+```java
+License license = new License();
+license.setLicense("path/to/license/file");
+```
+```
+
+## Uygulama rehberi
+Aşağıda, bir diyagramın her sayfasına metin filigranı eklemenin tam olarak nasıl yapılacağını adım adım gösteren bir rehber bulunmaktadır.
+
+### Bir diyagram sayfasına metin filigranı nasıl eklenir?
+Diyagramı yükleyin, bir `TextWatermark` nesnesi oluşturun, istediğiniz sayfalara uygulayın ve sonunda çıktıyı kaydedin. Bu uçtan uca akış sadece dört kısa API çağrısı gerektirir ve tipik 10 sayfalık dosyalar için bir saniyeden kısa sürede çalışır; ayrıca yazı tipi, renk, opaklık ve dönüş gibi özelleştirmelere izin verir.
+
+#### Adım 1: diyagramınızı yükleyin
+DiagramLoadOptions, kütüphaneye diyagram dosyalarını nasıl okuyacağını, şifreleri veya belirli format seçeneklerini nasıl ele alacağını söyler. İlk olarak, `DiagramLoadOptions` ile bir `Watermarker` örneği oluşturun. Bu nesne, bellekteki kaynak diyagramı temsil eder.
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### Adım 2: metin filigranını başlatın
+`TextWatermark`, görünen metni, yazı tipini, rengi ve dönüşü tanımlar. Filigranı hafif yapmak için opaklığı da ayarlayabilirsiniz.
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### Adım 3: diyagram sayfalarına filigran ekleyin
+DiagramShapeWatermarkOptions, bir filigranın diyagram şekillerine nasıl uygulanacağını yapılandırır. DiagramWatermarkPlacementType, filigranın ön planda mı yoksa arka planda mı görüneceğini belirler. Filigranı tüm arka plan sayfalarına (veya özel bir sayfa aralığına) uygulayın. API her sayfayı akış olarak işler, bu yüzden büyük dosyalarda bile bellek kullanımı düşük kalır.
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### Adım 4: kaydedin ve kapatın
+Filigranlı diyagramı yeni bir dosyaya kaydedin ve kaynakları serbest bırakın.
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### Yaygın sorunlar ve çözümler
+- **Dosya yolu sorunları:** Mutlak yollar kullanın veya çalışma dizininin diyagram dosyalarınızın konumuyla eşleştiğini doğrulayın.
+- **Sürüm uyumsuzlukları:** GroupDocs.Watermark sürümleri belirli JDK sürümlerine bağlıdır; uyumlu bir JDK 8‑17 sürümü kullandığınızdan emin olun.
+- **Performans darboğazları:** Toplu işleme için tek bir `Watermarker` örneğini yeniden kullanın ve toplu işlem tamamlandıktan sonra `close()` metodunu çağırın.
+
+## Pratik uygulamalar
+Metin filigranları birçok gerçek dünya senaryosunda faydalıdır:
+
+1. **Belge güvenliği** – Rakiplerin sahip olduğunuz diyagramları yeniden kullanmasını önler.
+2. **Marka güçlendirme** – Şirket adını veya sloganını doğrudan her sayfaya ekler.
+3. **İş birliği takibi** – Diyagramı kimin düzenlediğini göstermek için kullanıcı baş harflerini veya zaman damgalarını ekler.
+
+## Performans değerlendirmeleri
+- **Bellek yönetimi:** Kütüphane sayfaları tembel (lazy) olarak işler; yerel kaynakları serbest bırakmak için her zaman `watermarker.close()` çağırın.
+- **Filigran boyutu:** Daha büyük yazı tipleri işlem süresini doğrusal olarak artırır; 12 pt bir font okunabilirlik ve hız açısından iyi bir dengedir.
+- **Toplu test:** Binlerce dosyaya ölçeklendirmeden önce filigran rutinini temsilci bir örnek üzerinde çalıştırın.
+
+## Sonuç
+Artık GroupDocs.Watermark kullanarak Java'da metinle diyagram sayfalarına **filigran ekleme** için eksiksiz, üretime hazır bir yönteme sahipsiniz. Bu özellik, görsel varlıklarınızı korumanın yanı sıra paylaşılan tüm diyagramlarda marka tutarlılığını da güçlendirir.
+
+### Sonraki adımlar
+- Ek görsel marka oluşturmak için görüntü filigranlarını keşfedin.
+- Çok katmanlı koruma için metin ve görüntü filigranlarını birleştirin.
+- Filigran akışını CI/CD boru hattınıza entegre ederek diyagram güvenliğini otomatikleştirin.
+
+## Sıkça sorulan sorular
+1. **GroupDocs.Watermark'ı diğer dosya formatları için kullanabilir miyim?**
+ Evet—PDF, DOCX, PPTX ve SVG dahil olmak üzere 50'den fazla format desteklenir.
+
+2. **Kaç tane filigran ekleyebileceğim konusunda bir sınırlama var mı?**
+ Katı bir sınır yok, ancak sayfa başına 10'dan fazla filigran eklemek render hızını etkileyebilir.
+
+3. **Bir diyagramdan filigranı nasıl kaldırırım?**
+ Mevcut filigranları tespit edip silmek için `Watermarker.removeWatermarks()` API'sını kullanın.
+
+4. **Sadece belirli sayfaları hedefleyebilir miyim?**
+ Kesinlikle—`WatermarkOptions`'ı bir sayfa aralığı veya özel bir koşul ile yapılandırın.
+
+5. **Filigran görünmüyorsa ne yapmalıyım?**
+ Opaklığı, renk kontrastını ve dönüş ayarlarını kontrol edin; sorun giderme için API belgelerine bakın.
+
+### Ek Soru&Cevap
+**S: Kütüphane şifre korumalı diyagramları destekliyor mu?**
+C: Evet—dosyayı yüklerken şifreyi `DiagramLoadOptions`'a geçirin.
+
+**S: Bunu başsız (headless) bir sunucuda çalıştırabilir miyim?**
+C: API tamamen sunucu taraflıdır ve GUI bileşenlerine ihtiyaç duymaz.
+
+**S: Hangi Java sürümleri resmi olarak destekleniyor?**
+C: Java 8'den Java 17'ye kadar test edilmiş ve belgelenmiştir.
+
+**S: GroupDocs.Watermark büyük dosyalarla nasıl başa çıkıyor?**
+C: Sayfaları akış olarak işler, 1 GB'lik diyagramlarda bile en yüksek bellek kullanımını 200 MB'in altında tutar.
+
+**S: Kaydetmeden önce filigranı önizlemek mümkün mü?**
+C: Herhangi bir sayfanın önizleme bitmap'ini oluşturmak için `Watermarker.getResultImage()` kullanın.

+# Java'da GroupDocs.Watermark kullanarak diyagram görüntülerini değiştirin
+
+Diyagram dosyalarındaki görüntüleri manuel olarak güncellemek zaman alıcı ve hataya açıktır. Bu öğreticide sadece birkaç satır kodla **Java'da diyagram görüntülerini değiştirmeyi** öğrenecek ve gerektiğinde **diyagrama filigran eklemeyi** de göreceksiniz. Sonunda Visio, Draw.io veya diğer desteklenen diyagram formatlarıyla çalışan herhangi bir Java projesine ekleyebileceğiniz yeniden kullanılabilir bir kod parçacığına sahip olacaksınız.
+
+## Hızlı cevaplar
+- **Diyagram görüntüsü değişimini hangi kütüphane yönetir?** GroupDocs.Watermark for Java.
+- **Temel bir değişim için kaç satır kod gerekir?** Watermarker oluşturulduktan sonra sadece üç satır.
+- **Aynı anda bir filigran ekleyebilir miyim?** Evet – aynı Watermarker örneğini bir filigran nesnesiyle kullanın.
+- **Hangi Java sürümü gereklidir?** JDK 8 veya üzeri.
+- **Üretim kullanımında lisansa ihtiyacım var mı?** Geçerli bir GroupDocs.Watermark lisansı gereklidir; ücretsiz deneme sürümü mevcuttur.
+
+## Java'da diyagram görüntülerini değiştirme nedir?
+Java'da diyagram görüntülerini değiştirmek, bir diyagram dosyası (.vsdx, .drawio veya .svg gibi) içinde bitmap grafik içeren şekilleri programlı olarak bulmak ve bu gömülü görüntüleri GroupDocs.Watermark API'si kullanarak yeni görüntülerle değiştirmek anlamına gelir. Bu, aksi takdirde bir diyagram düzenleyicisinde manuel olarak yapılması gereken güncellemeleri otomatikleştirir.
+
+## Diyagram görüntüsü değişimi için neden GroupDocs.Watermark kullanılmalı?
+GroupDocs.Watermark **50+ giriş ve çıkış formatını** destekler – Visio, Draw.io ve SVG dahil – ve belgeyi belleğe tamamen yüklemeden **500 MB'a kadar dosyaları** işleyebilir, bu da naif dosya akışı yaklaşımlarına göre **CPU kullanımında %30 azalma** sağlar.
+
+## Önkoşullar
+- JDK 8 veya daha yeni bir sürüm yüklü.
+- Java geliştirme için bir IDE (IntelliJ IDEA, Eclipse veya VS Code).
+- Maven (veya JAR'ları manuel ekleme yeteneği).
+- Geçerli bir GroupDocs.Watermark lisansı (deneme veya kalıcı). Lisansı [GroupDocs](https://purchase.groupdocs.com/temporary-license/) adresinden edinebilirsiniz.
+
+### Gerekli kütüphaneler, sürümler ve bağımlılıklar
+GroupDocs.Watermark deposunu ve bağımlılığını `pom.xml` dosyanıza ekleyin:
+
+```xml
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Manuel JAR yönetimini tercih ediyorsanız, resmi siteden en son sürümü indirin: [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/).
+
+## Java'da diyagram görüntülerini adım adım nasıl değiştirilir
+
+### Bir diyagram dosyası için Watermarker nasıl başlatılır?
+Watermarker, bir belgeyi temsil eden ve içerik manipülasyonu için yöntemler sağlayan ana sınıftır. Başlamak için diyagram dosyasını belleğe yükleyen bir `Watermarker` nesnesi oluşturun. `Watermarker` sınıfı, GroupDocs.Watermark'ın temel giriş noktasıdır ve belgeleri okumanıza, değiştirmenize ve kaydetmenize olanak tanır. DPI veya sayfa aralığı gibi format‑özel ayarları belirtmek için `DiagramLoadOptions` kullanın. `DiagramLoadOptions`, bir diyagramın nasıl yükleneceğini yapılandırır; örneğin DPI veya yükleme modunu ayarlamak gibi.
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### Şekilleri bulmak için diyagram içeriğine nasıl erişilir?
+Dosya yüklendikten sonra `Watermarker` üzerinden bir `DiagramContent` nesnesi alın. `DiagramContent`, diyagramın sayfalar ve şekiller içindeki iç hiyerarşisini temsil eder. Bu model, sayfa ve şekil koleksiyonlarını ortaya çıkarır; bu koleksiyonlar üzerinde döngü kurarak görüntü veya metin gibi belirli öğeleri kolayca bulabilirsiniz.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### Diyagramda şekil görüntüleri nasıl değiştirilir?
+İstenen sayfadaki her `DiagramShape` üzerinde döngü yapın, şeklin bir görüntü içerip içermediğini kontrol edin ve görüntü baytlarını yeni bir dosyanın baytlarıyla değiştirin. `DiagramShape`, diyagramdaki tek bir şeklin modelidir; `DiagramWatermarkableImage` ise bir şekle uygulanabilecek görüntü verilerini saklar.
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### Değişiklikleri nasıl kaydedip Watermarker'ı kapatırsınız?
+Tüm değişiklikler tamamlandığında, güncellenen diyagramı bir dosyaya yazmak için `Watermarker` üzerinde `save` metodunu çağırın, ardından yerel kaynakları serbest bırakmak için `close` metodunu çalıştırın. Bu, dosya tanıtıcılarının serbest bırakılmasını sağlar ve özellikle toplu işte birçok diyagram işlenirken bellek sızıntılarını önler.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+
+public class FeatureSaveAndCloseWatermarker {
+ public static void run(Watermarker watermarker) throws Exception {
+ String outputPath = "YOUR_OUTPUT_DIRECTORY/output.vsdx";
+ watermarker.save(outputPath);
+ watermarker.close();
+ }
+}
+```
+```
+
+## Aynı diyagrama filigran ekleme (isteğe bağlı)
+
+Diyagramı markalamak da istiyorsanız, görüntü değişiminden önce ya da sonra bir filigran ekleyebilirsiniz:
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+
+## Yaygın tuzaklar ve sorun giderme
+
+| Semptom | Muhtemel neden | Çözüm |
+|---------|----------------|-------|
+| Kod çalıştırıldıktan sonra görüntü değişmedi | `DiagramShape.hasImage()` false döndürdü | Şekil tipini doğrulayın; bazı vektör şekilleri görüntüleri farklı şekilde depolar. |
+| Büyük dosyalarda OutOfMemoryError | Diyagramın tamamını bir kerede yüklemek | `DiagramLoadOptions.setLoadMode(LoadMode.Stream)` kullanarak sayfaları sıralı işleyin. |
+| Filigran görünmüyor | Filigran mevcut içeriğin arkasına yerleştirildi | Kaydetmeden önce `watermarker.setWatermarkPosition(Position.Foreground)` metodunu çağırın. |
+
+## Sıkça sorulan sorular
+
+**S: Parola korumalı diyagramlardaki görüntüleri değiştirebilir miyim?**
+C: Evet. `Watermarker` oluştururken parolayı `DiagramLoadOptions`'a geçirin.
+
+**S: Kütüphane .drawio (XML) dosyalarıyla çalışıyor mu?**
+C: Kesinlikle – GroupDocs.Watermark Draw.io XML formatını destekler ve her düğümü bir şekil olarak ele alır.
+
+**S: Aynı anda kaç diyagram işleyebilirim?**
+C: Kütüphane sadece okuma işlemleri için iş parçacığı güvenlidir; yazma işlemleri için dosya tanıtıcı çakışmasını önlemek amacıyla eşzamanlılığı CPU çekirdek sayısıyla sınırlayın.
+
+**S: Görüntü boyutu için bir limit var mı?**
+C: 100 MB'a kadar görüntüler desteklenir; daha büyük dosyalar bellek kullanımını düşük tutmak için önceden yeniden boyutlandırılmalıdır.
+
+**S: Hangi lisans seçenekleri mevcuttur?**
+C: Ücretsiz 30‑günlük deneme ile başlayabilirsiniz; üretim kullanımı için ücretli bir lisans gerekir ve bu lisans GroupDocs mağazasından temin edilebilir.

+# Zekâ mülkiyeti diyagramlarını GroupDocs.Watermark ile koruyun
+
+Zekâ mülkiyeti diyagramlarını korumak, tasarım varlıkları, akış şemaları veya mimari çizimler paylaşan her kuruluş için kritik bir adımdır. GroupDocs.Watermark for Java ile diyagram dosyalarını (örneğin `.vsdx`) programlı olarak yükleyebilir, görüntü watermark örneklerini tespit edebilir, metin watermark'larını arayabilir ve orijinal çizimi bozmadan güvenli bir şekilde kaldırabilirsiniz. Bu öğretici, ortam kurulumundan büyük diyagram kütüphanelerinin toplu işlenmesine kadar tüm süreci adım adım anlatır; böylece Java uygulamalarınıza sağlam bir IP koruması yerleştirebilirsiniz.
+
+## Hızlı cevaplar
+- **Hangi kütüphane diyagram watermark'larını yönetir?** GroupDocs.Watermark for Java.
+- **Görüntü watermark'ını da metin watermark'ını da tespit edebilir miyim?** Evet, API `ImageDctHashSearchCriteria` sınıfını görüntü tespiti için ve `TextSearchCriteria` sınıfını metin için sağlar.
+- **Kodu çalıştırmak için ticari bir lisansa ihtiyacım var mı?** Geliştirme için deneme lisansı yeterlidir; üretim için ücretli lisans gereklidir.
+- **Toplu işleme destekleniyor mu?** Kesinlikle—bir klasörü döngüyle işleyip aynı watermark mantığını her dosyaya uygulayabilirsiniz.
+- **Kaldırma işleminden sonra orijinal diyagram düzeni korunur mu?** Kütüphane yalnızca watermark nesnelerini temizler, tüm şekilleri, bağlayıcıları ve biçimlendirmeyi korur.
+
+## Zekâ mülkiyeti diyagramları nedir?
+Zekâ mülkiyeti diyagramları, akış şemaları, UML modelleri, ağ şemaları veya mimari çizimler gibi görsel temsillerdir ve birey ya da kuruluşun sahip olduğu özel bilgileri içerir. Bu diyagramlar genellikle gizli süreçleri, tasarımları veya stratejileri iletir ve yetkisiz kopyalama, dağıtım veya değiştirilmelere karşı korunması gereken değerli varlıklardır. Onları zekâ mülkiyeti olarak ele alarak, watermark'lama dahil olmak üzere yasal ve teknik koruma önlemleri uygulayabilir, kullanım ve yayılımı üzerinde kontrol sağlayabilirsiniz.
+
+## Neden GroupDocs.Watermark for Java Kullanmalısınız?
+GroupDocs.Watermark **50+ giriş ve çıkış formatını** (`.vsdx`, `.vdx`, `.vsx` dahil) destekler ve tüm dosyayı belleğe yüklemeden çok sayfalı diyagramları işleyebilir; bu sayede naif dosya akışı yaklaşımlarına göre RAM tüketimini **%70** kadar azaltır. API ayrıca OCR'suz yerleşik görüntü‑hash karşılaştırması sunar ve tipik bir 2.5 GHz sunucuda bir diyagram başına **200 ms** altında güvenilir `detect image watermark` işlemleri yapmanıza olanak tanır.
+
+## Önkoşullar
+Başlamadan önce şunların olduğundan emin olun:
+
+1. **Java Development Kit (JDK) 8+** – kod standart Java 8 API'lerini kullanır.
+2. **IDE** – IntelliJ IDEA, Eclipse veya tercih ettiğiniz herhangi bir editör.
+3. **GroupDocs.Watermark for Java** – Maven üzerinden ya da manuel JAR indirmesiyle.
+
+### Gerekli kütüphaneler ve bağımlılıklar
+Kütüphaneyi Maven aracılığıyla ekleyebilir veya JAR'ları doğrudan indirebilirsiniz.

+
+## Watermarker Nasıl Başlatılır?
+`Watermarker` örneği oluşturmak, herhangi bir watermark iş akışının ilk adımıdır. `Watermarker` sınıfı bir diyagram dosyasını belleğe yükler ve watermark'ları arama, ekleme ve kaldırma yöntemleri sunar. Diyagram yolunu ve isteğe bağlı `DiagramLoadOptions` parametresini geçirerek, sonraki tüm işlemler için merkezi bir nokta olan bir nesne elde eder ve belgeyi süreç boyunca tutarlı bir şekilde yönetirsiniz.
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## Bir Diyagram Belgesi Nasıl Yüklenir?
+`DiagramLoadOptions` ile bir diyagram yüklemek, dosyanın nasıl ayrıştırılacağı üzerinde ayrıntılı kontrol sağlar. `DiagramLoadOptions`, yalnızca görünür sayfaların yüklenip yüklenmeyeceğini, gizli katmanların korunup korunmayacağını ve gömülü yazı tiplerinin nasıl ele alınacağını belirlemenize izin verir. Bu seçenekleri ayarlamak, büyük diyagramlarda performansı önemli ölçüde artırabilir ve dosyanın yalnızca gerekli bölümlerinin işlenmesini sağlayarak bellek kullanımını azaltır ve watermark tespitini hızlandırır.
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## Bir Diyagramda Görüntü Watermark Nasıl Tespit Edilir?
+Görüntü watermark'larını tespit etmek, referans görüntünün algısal hash'ini hesaplayan ve diyagramdaki tüm gömülü görüntülerle karşılaştıran `ImageDctHashSearchCriteria` sınıfına dayanır. Bu yöntem hızlıdır ve küçük görsel farklılıklara toleranslıdır; böylece yeniden boyutlandırılmış veya hafifçe değiştirilmiş logoları ya da diğer grafik watermark'ları bulabilirsiniz. Benzerlik eşiğini yapılandırarak, tespit duyarlılığını yanlış pozitif eşleşmelerle dengeleyebilirsiniz.
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## Metin Watermark'ları Nasıl Aranır?
+Metin watermark'larını aramak, `TextSearchCriteria` sınıfını kullanır. Bu sınıf, şekiller, bağlayıcılar ve gruplamalar içindeki katmanlar dahil, diyagramdaki tüm metin katmanlarını tarar ve belirtilen dizeyi veya deseni içeren eşleşmeleri döndürür. Arama varsayılan olarak büyük/küçük harfe duyarsızdır ve düzenli ifadelerle geliştirilebilir; böylece döndürülmüş, kısmen gizlenmiş veya karmaşık diyagram yapılarında gömülü watermark'ları bulabilirsiniz.
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## Bir Diyagramdan Watermark'lar Nasıl Kaldırılır?
+Watermark'ları kaldırmak, bir arama işlemiyle dönen her `Watermark` nesnesi üzerinde `clear()` metodunu çağırarak yapılır. `clear()` metodu yalnızca görsel watermark öğelerini siler, alttaki diyagram nesnelerini—şekiller, bağlayıcılar ve biçimlendirme gibi—korur. Temizleme işleminden sonra, `save` metodunu kullanarak belgeyi kaydedersiniz; bu, orijinal düzeni ve işlevselliği koruyan temiz bir diyagram sürümü üretir.
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## Pratik uygulamalar
+- **Kurumsal yazılım entegrasyonu:** Watermark doğrulamasını belge yönetim sistemlerine yerleştirerek IP politikalarını otomatik olarak uygulayın.
+- **İçerik yönetim sistemleri (CMS):** Yayınlamadan önce kullanıcı tarafından yüklenen diyagramlarda yetkisiz logoları tarayın.
+- **Hukuki belge yönetimi:** Delil paketleri hazırlarken gizli watermark'ları tespit edip kaldırın.
+
+## Yaygın tuzaklar ve sorun giderme
+- **Lisans eksikliği istisnası:** Deneme veya ücretli lisans dosyasının `License.setLicense("license_path")` ile doğru şekilde referans edildiğinden emin olun.
+- **Büyük diyagram yavaşlaması:** `loadOptions.setLoadHiddenLayers(false)` etkinleştirin ve diyagramları paralel akışlarda işlemeyi düşünün.
+- **Yanlış pozitif görüntü eşleşmeleri:** `criteria.setSimilarityThreshold(0.85)` ile DCT hash toleransını ayarlayarak yanlış eşleşmeleri azaltın.
+
+## Sıkça Sorulan Sorular
+
+**S: Tek bir çağrıda hem metin hem de görüntü watermark'larını arayabilir miyim?**
+C: Evet, kriterleri `OrSearchCriteria` ile birleştirerek (örneğin, `new OrSearchCriteria(textCriteria, imageCriteria)`) her iki türü de aynı anda alabilirsiniz.
+
+**S: Watermark'ları kaldırmak diyagram düzenini bozacak mı?**
+C: Hayır. Kütüphane watermark nesnelerini izole eder, bu yüzden `clear()` sonrası şekiller, bağlayıcılar ve biçimlendirme değişmez.
+
+**S: Hangi diyagram formatları destekleniyor?**
+C: GroupDocs.Watermark `.vsdx`, `.vdx`, `.vsx` ve birkaç eski Visio formatını işleyerek **30**'dan fazla diyagram türünü kapsar.
+
+**S: Binlerce diyagramı verimli bir şekilde nasıl işlerim?**
+C: Java’nın `ExecutorService`'ini kullanarak watermark tespiti/kaldırma işlemlerini paralel toplu olarak çalıştırın ve aşırı yükü azaltmak için tek bir `Watermarker` yapılandırma nesnesini yeniden kullanın.
+
+**S: Bunu bir CI/CD boru hattına entegre etmek mümkün mü?**
+C: Kesinlikle. Java kod parçacıklarını derleme betiklerinize (Maven/Gradle) ekleyin ve dağıtıma öncesinde bir doğrulama adımı olarak çalıştırarak yasaklı watermark'ların bulunmadığını garantileyin.

+# Cách đánh dấu trang sơ đồ bằng văn bản trong Java
+
+Trong các dự án phần mềm hiện đại, việc bảo vệ các tài sản hình ảnh bạn chia sẻ—đặc biệt là sơ đồ—đã trở thành ưu tiên hàng đầu. **How to watermark diagram** pages with text in Java là một yêu cầu phổ biến cho các công ty cần duy trì nhận diện thương hiệu, ngăn chặn việc sử dụng trái phép và theo dõi nguồn gốc tài liệu. Hướng dẫn này sẽ đưa bạn qua toàn bộ quy trình sử dụng **GroupDocs.Watermark for Java**, từ chuẩn bị môi trường đến xác minh cuối cùng, để bạn có thể tự tin bảo vệ các sơ đồ của mình.
+
+## Câu trả lời nhanh
+- **Thư viện nào thêm dấu watermark?** GroupDocs.Watermark for Java.
+- **Phiên bản Java nào được yêu cầu?** JDK 8 hoặc mới hơn.
+- **Tôi có cần giấy phép để thử nghiệm không?** Một giấy phép tạm thời miễn phí hoạt động cho việc đánh giá.
+- **Tôi có thể đánh dấu nhiều trang cùng lúc không?** Có—áp dụng watermark cho tất cả các trang trong một lần gọi.
+- **Quá trình có tiết kiệm bộ nhớ không?** API truyền dữ liệu các trang, vì vậy ngay cả sơ đồ 500 trang cũng chỉ sử dụng dưới 200 MB RAM.
+
+## Watermark các trang sơ đồ trong Java là gì?
+Nó liên quan đến việc chồng lên một cách lập trình văn bản (hoặc hình ảnh) bán trong suốt lên mỗi trang của tệp sơ đồ—như Visio, SVG, hoặc các định dạng được hỗ trợ khác—bằng một thư viện Java. Watermark trở thành một phần của nội dung hình ảnh, hiển thị trong bất kỳ trình xem nào đồng thời bảo tồn dữ liệu sơ đồ gốc.
+
+## Tại sao nên sử dụng GroupDocs.Watermark cho Java?
+GroupDocs.Watermark hỗ trợ **hơn 50 định dạng đầu vào và đầu ra**, xử lý các tệp lên tới **1 GB** mà không cần tải toàn bộ tài liệu vào bộ nhớ, và cung cấp **OCR tích hợp** để phát hiện các watermark hiện có. Những khả năng định lượng này đảm bảo bảo vệ nhanh chóng, đáng tin cậy cho các kho sơ đồ quy mô lớn, trong khi API của nó đơn giản hoá việc tích hợp vào các ứng dụng Java.
+
+## Yêu cầu trước
+- **Java Development Kit (JDK)** 8 hoặc cao hơn được cài đặt trên máy của bạn.
+- Một IDE như **IntelliJ IDEA** hoặc **Eclipse** để chỉnh sửa và chạy mã Java.
+- Kiến thức cơ bản về Maven để quản lý phụ thuộc.
+
+### Thư viện và phụ thuộc cần thiết
+Chúng ta sẽ sử dụng GroupDocs.Watermark cho Java, mà bạn có thể thêm vào dự án Maven của mình:
+
+```xml
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+```
+
+Nếu bạn muốn thiết lập thủ công, tải các tệp nhị phân từ trang phát hành chính thức [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/) và thêm chúng vào classpath của dự án.
+
+### Nhận giấy phép
+Bắt đầu với bản dùng thử miễn phí bằng cách lấy giấy phép tạm thời từ [GroupDocs.Trial Licensing](https://purchase.groupdocs.com/temporary-license/). Đối với sử dụng trong môi trường sản xuất, mua giấy phép đầy đủ và đặt tệp `license.json` ở vị trí mà ứng dụng của bạn có thể đọc được:
+
+```java
+// Load the temporary or purchased license – keep unchanged
+```java
+License license = new License();
+license.setLicense("path/to/license/file");
+```
+```
+
+## Hướng dẫn triển khai
+Dưới đây là hướng dẫn chi tiết từng bước cho thấy cách nhúng watermark văn bản vào mỗi trang của một sơ đồ.
+
+### Làm thế nào để thêm watermark văn bản vào một trang sơ đồ?
+Tải sơ đồ, tạo một đối tượng `TextWatermark`, áp dụng nó vào các trang mong muốn, và cuối cùng lưu kết quả. Quy trình end‑to‑end này chỉ yêu cầu bốn lời gọi API ngắn gọn và chạy dưới một giây cho các tệp thường gặp 10 trang, đồng thời cho phép tùy chỉnh phông chữ, màu sắc, độ trong suốt và góc quay.
+
+#### Bước 1: tải sơ đồ của bạn
+DiagramLoadOptions cho thư viện biết cách đọc các tệp sơ đồ, chẳng hạn như xử lý mật khẩu hoặc các tùy chọn định dạng cụ thể. Đầu tiên, khởi tạo một `Watermarker` với `DiagramLoadOptions`. Đối tượng này đại diện cho sơ đồ nguồn trong bộ nhớ.
+
+```java
+// Load diagram – keep unchanged
+```java
+String inputFilePath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+Watermarker watermarker = new Watermarker(inputFilePath, new DiagramLoadOptions());
+```
+```
+
+#### Bước 2: khởi tạo watermark văn bản
+`TextWatermark` định nghĩa văn bản hiển thị, phông chữ, màu sắc và góc quay. Bạn cũng có thể đặt độ trong suốt để làm watermark nhẹ nhàng hơn.
+
+```java
+// Create TextWatermark – keep unchanged
+```java
+TextWatermark textWatermark = new TextWatermark("Test watermark", new Font("Arial", 36));
+textWatermark.setColor(Color.getBlue());
+textWatermark.setBackground(false);
+textWatermark.setRotationAngle(-45);
+```
+```
+
+#### Bước 3: thêm watermark vào các trang sơ đồ
+DiagramShapeWatermarkOptions cấu hình cách watermark được áp dụng lên các hình dạng trong sơ đồ. DiagramWatermarkPlacementType xác định watermark sẽ xuất hiện ở tiền cảnh hay hậu cảnh. Áp dụng watermark cho tất cả các trang nền (hoặc một phạm vi trang tùy chỉnh). API truyền dữ liệu từng trang, vì vậy mức sử dụng bộ nhớ vẫn thấp ngay cả với các tệp lớn.
+
+```java
+// Apply watermark – keep unchanged
+```java
+DiagramShapeWatermarkOptions options = new DiagramShapeWatermarkOptions();
+options.setPlacement(DiagramWatermarkPlacementType.Background);
+watermarker.add(textWatermark, options);
+```
+```
+
+#### Bước 4: lưu và đóng
+Lưu sơ đồ đã được watermark vào một tệp mới và giải phóng tài nguyên.
+
+```java
+// Save and close – keep unchanged
+```java
+String outputFilePath = "YOUR_OUTPUT_DIRECTORY/watermarked_diagram.vsdx";
+watermarker.save(outputFilePath);
+watermarker.close();
+```
+```
+
+### Các vấn đề thường gặp và giải pháp
+- **Vấn đề đường dẫn tệp:** Sử dụng đường dẫn tuyệt đối hoặc xác minh rằng thư mục làm việc khớp với vị trí các tệp sơ đồ của bạn.
+- **Không khớp phiên bản:** Các bản phát hành GroupDocs.Watermark gắn với các phiên bản JDK cụ thể; đảm bảo bạn đang sử dụng bản JDK 8‑17 tương thích.
+- **Nút thắt hiệu năng:** Đối với xử lý hàng loạt, tái sử dụng một thể hiện `Watermarker` duy nhất và gọi `close()` chỉ sau khi batch hoàn thành.
+
+## Ứng dụng thực tiễn
+Watermark văn bản hữu ích trong nhiều tình huống thực tế:
+
+1. **Bảo mật tài liệu** – Ngăn chặn đối thủ tái sử dụng các sơ đồ sở hữu.
+2. **Củng cố thương hiệu** – Nhúng tên công ty hoặc khẩu hiệu trực tiếp lên mỗi trang.
+3. **Theo dõi cộng tác** – Thêm chữ ký người dùng hoặc dấu thời gian để chỉ ra ai đã chỉnh sửa sơ đồ.
+
+## Các yếu tố hiệu năng
+- **Quản lý bộ nhớ:** Thư viện xử lý các trang một cách lười biếng; luôn gọi `watermarker.close()` để giải phóng tài nguyên gốc.
+- **Kích thước watermark:** Kích thước phông chữ lớn hơn làm tăng thời gian xử lý theo tỷ lệ; phông 12‑pt là cân bằng tốt cho khả năng đọc và tốc độ.
+- **Kiểm tra batch:** Chạy quy trình watermark trên một mẫu đại diện trước khi mở rộng lên hàng ngàn tệp.
+
+## Kết luận
+Bạn hiện đã có một phương pháp hoàn chỉnh, sẵn sàng cho sản xuất để **how to watermark diagram** pages with text in Java using GroupDocs.Watermark. Khả năng này không chỉ bảo vệ các tài sản hình ảnh của bạn mà còn củng cố tính nhất quán thương hiệu trên tất cả các sơ đồ được chia sẻ.
+
+### Các bước tiếp theo
+- Khám phá watermark hình ảnh để tăng cường thương hiệu trực quan.
+- Kết hợp watermark văn bản và hình ảnh để bảo vệ đa lớp.
+- Tích hợp quy trình watermark vào pipeline CI/CD của bạn để tự động hoá bảo mật sơ đồ.
+
+## Câu hỏi thường gặp
+1. **Tôi có thể sử dụng GroupDocs.Watermark cho các định dạng tệp khác không?**
+ Có—hơn 50 định dạng, bao gồm PDF, DOCX, PPTX và SVG, được hỗ trợ.
+
+2. **Có giới hạn số lượng watermark tôi có thể thêm không?**
+ Không có giới hạn cứng, nhưng thêm hơn 10 watermark mỗi trang có thể ảnh hưởng đến tốc độ render.
+
+3. **Làm sao để xóa watermark khỏi một sơ đồ?**
+ Sử dụng API `Watermarker.removeWatermarks()` để phát hiện và xóa các watermark hiện có.
+
+4. **Tôi có thể chỉ nhắm mục tiêu các trang cụ thể không?**
+ Chắc chắn—cấu hình `WatermarkOptions` với phạm vi trang hoặc một predicate tùy chỉnh.
+
+5. **Nếu watermark không hiển thị, tôi nên làm gì?**
+ Kiểm tra độ trong suốt, độ tương phản màu và cài đặt góc quay; tham khảo tài liệu API để khắc phục.
+
+### Câu hỏi & Trả lời bổ sung
+**Q: Thư viện có hỗ trợ sơ đồ được bảo vệ bằng mật khẩu không?**
+A: Có—truyền mật khẩu vào `DiagramLoadOptions` khi tải tệp.
+
+**Q: Tôi có thể chạy điều này trên máy chủ không có giao diện không?**
+A: API hoàn toàn chạy phía server và không yêu cầu thành phần GUI.
+
+**Q: Các phiên bản Java nào được hỗ trợ chính thức?**
+A: Java 8 đến Java 17 đã được kiểm tra và tài liệu hoá.
+
+**Q: GroupDocs.Watermark xử lý các tệp lớn như thế nào?**
+A: Nó truyền dữ liệu các trang, giữ mức sử dụng bộ nhớ tối đa dưới 200 MB ngay cả với sơ đồ 1 GB.
+
+**Q: Có cách nào xem trước watermark trước khi lưu không?**
+A: Sử dụng `Watermarker.getResultImage()` để tạo bitmap xem trước của bất kỳ trang nào.

+# Thay thế hình ảnh sơ đồ trong Java bằng GroupDocs.Watermark
+
+Việc cập nhật hình ảnh trong các tệp sơ đồ một cách thủ công tốn thời gian và dễ gây lỗi. Trong hướng dẫn này, bạn sẽ học cách **thay thế hình ảnh sơ đồ trong Java** chỉ với vài dòng mã, và bạn cũng sẽ thấy cách **thêm watermark vào sơ đồ** khi cần. Khi hoàn thành, bạn sẽ có một đoạn mã có thể tái sử dụng và chèn vào bất kỳ dự án Java nào làm việc với Visio, Draw.io hoặc các định dạng sơ đồ được hỗ trợ khác.
+
+## Câu trả lời nhanh
+- **Thư viện nào xử lý việc thay thế hình ảnh sơ đồ?** GroupDocs.Watermark for Java.
+- **Cần bao nhiêu dòng mã cho một lần thay thế cơ bản?** Chỉ ba dòng sau khi Watermarker được tạo.
+- **Tôi có thể thêm watermark cùng lúc không?** Có – sử dụng cùng một thể hiện Watermarker với một đối tượng watermark.
+- **Phiên bản Java nào được yêu cầu?** JDK 8 hoặc cao hơn.
+- **Tôi có cần giấy phép cho việc sử dụng trong môi trường sản xuất không?** Cần một giấy phép GroupDocs.Watermark hợp lệ; có sẵn bản dùng thử miễn phí.
+
+## Thay thế hình ảnh sơ đồ trong Java là gì?
+Thay thế hình ảnh sơ đồ trong Java có nghĩa là tìm kiếm các hình dạng chứa đồ họa bitmap bên trong tệp sơ đồ (như .vsdx, .drawio hoặc .svg) một cách lập trình và thay thế các hình ảnh nhúng bằng các hình ảnh mới bằng cách sử dụng API của GroupDocs.Watermark. Điều này tự động hoá các cập nhật mà nếu không sẽ phải chỉnh sửa thủ công trong trình chỉnh sửa sơ đồ.
+
+## Tại sao nên sử dụng GroupDocs.Watermark để thay thế hình ảnh sơ đồ?
+GroupDocs.Watermark hỗ trợ **hơn 50 định dạng đầu vào và đầu ra** – bao gồm Visio, Draw.io và SVG – và có thể xử lý **các tệp lên tới 500 MB** mà không cần tải toàn bộ tài liệu vào bộ nhớ, mang lại **giảm 30 % mức sử dụng CPU** so với các phương pháp xử lý luồng tệp đơn giản.
+
+## Yêu cầu trước
+- JDK 8 hoặc mới hơn đã được cài đặt.
+- Một IDE (IntelliJ IDEA, Eclipse hoặc VS Code) để phát triển Java.
+- Maven (hoặc khả năng thêm JAR thủ công).
+- Một giấy phép GroupDocs.Watermark hợp lệ (bản dùng thử hoặc vĩnh viễn). Bạn có thể lấy giấy phép từ [GroupDocs](https://purchase.groupdocs.com/temporary-license/).
+

+
+## Cách thay thế hình ảnh sơ đồ trong Java từng bước
+
+### Làm thế nào để khởi tạo Watermarker cho một tệp sơ đồ?
+Watermarker là lớp chính đại diện cho một tài liệu và cung cấp các phương thức để thao tác nội dung. Để bắt đầu, tạo một đối tượng `Watermarker` tải tệp sơ đồ vào bộ nhớ. Lớp `Watermarker` là điểm vào cốt lõi của GroupDocs.Watermark, cho phép bạn đọc, sửa đổi và lưu tài liệu. Sử dụng `DiagramLoadOptions` để chỉ định các cài đặt riêng cho định dạng như DPI hoặc phạm vi trang. `DiagramLoadOptions` cấu hình cách một sơ đồ được tải, ví dụ, đặt DPI hoặc chế độ tải.
+
+```java
+```java
+import java.io.File;
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.options.DiagramLoadOptions;
+
+public class FeatureWatermarkerInitialization {
+ public static void run() throws Exception {
+ DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+ String documentPath = "YOUR_DOCUMENT_DIRECTORY/diagram.vsdx";
+ Watermarker watermarker = new Watermarker(documentPath, loadOptions);
+ }
+}
+```
+```
+
+### Làm thế nào để truy cập nội dung sơ đồ để tìm các hình dạng?
+Sau khi tải tệp, lấy một đối tượng `DiagramContent` từ `Watermarker`. `DiagramContent` đại diện cho cấu trúc nội bộ của sơ đồ gồm các trang và hình dạng. Mô hình này cung cấp các bộ sưu tập các trang và hình dạng mà bạn có thể lặp qua, giúp dễ dàng tìm các phần tử cụ thể như hình ảnh hoặc văn bản.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureAccessDiagramContent {
+ public static void run(Watermarker watermarker) throws Exception {
+ DiagramContent content = watermarker.getContent(DiagramContent.class);
+ }
+}
+```
+```
+
+### Làm thế nào để thay thế hình ảnh của các hình dạng trong sơ đồ?
+Lặp qua mỗi `DiagramShape` trên trang mong muốn, kiểm tra xem hình dạng có chứa hình ảnh không, và thay thế byte hình ảnh bằng byte của tệp mới. `DiagramShape` là mô hình cho một hình dạng riêng lẻ trong sơ đồ, trong khi `DiagramWatermarkableImage` lưu trữ dữ liệu hình ảnh có thể áp dụng cho một hình dạng.
+
+```java
+```java
+import java.io.File;
+import java.io.FileInputStream;
+import java.io.InputStream;
+import com.groupdocs.watermark.contents.DiagramShape;
+import com.groupdocs.watermark.contents.DiagramWatermarkableImage;
+import com.groupdocs.watermark.contents.DiagramContent;
+
+public class FeatureReplaceShapeImages {
+ public static void run(DiagramContent content) throws Exception {
+ for (DiagramShape shape : content.getPages().get_Item(0).getShapes()) {
+ if (shape.getImage() != null) {
+ File imageFile = new File("YOUR_DOCUMENT_DIRECTORY/test.png");
+ byte[] imageBytes = new byte[(int) imageFile.length()];
+ InputStream imageInputStream = new FileInputStream(imageFile);
+ imageInputStream.read(imageBytes);
+ imageInputStream.close();
+
+ shape.setImage(new DiagramWatermarkableImage(imageBytes));
+ }
+ }
+ }
+}
+```
+```
+
+### Làm thế nào để lưu các thay đổi và đóng Watermarker?
+Khi tất cả các sửa đổi đã hoàn tất, gọi `save` trên `Watermarker` để ghi sơ đồ đã cập nhật vào tệp, sau đó gọi `close` để giải phóng tài nguyên gốc. Điều này đảm bảo các handle tệp được giải phóng và ngăn ngừa rò rỉ bộ nhớ, đặc biệt khi xử lý nhiều sơ đồ trong một công việc batch.
+
+```java
+```java
+import com.groupdocs.watermark.Watermarker;
+
+public class FeatureSaveAndCloseWatermarker {
+ public static void run(Watermarker watermarker) throws Exception {
+ String outputPath = "YOUR_OUTPUT_DIRECTORY/output.vsdx";
+ watermarker.save(outputPath);
+ watermarker.close();
+ }
+}
+```
+```
+
+## Thêm watermark vào cùng một sơ đồ (tùy chọn)
+
+Nếu bạn cũng cần gắn thương hiệu vào sơ đồ, bạn có thể thêm watermark trước hoặc sau khi thay thế hình ảnh:
+
+```java
+// Example – adding a text watermark
+Watermark watermark = new TextWatermark("Confidential", new Font("Arial", 12));
+watermarker.add(watermark);
+```
+
+## Các lỗi thường gặp và cách khắc phục
+
+| Triệu chứng | Nguyên nhân khả dĩ | Cách khắc phục |
+|------------|----------------------|----------------|
+| Không có thay đổi hình ảnh sau khi chạy mã | `DiagramShape.hasImage()` trả về false | Xác minh loại hình dạng; một số hình dạng vector lưu trữ hình ảnh khác nhau. |
+| Lỗi OutOfMemoryError trên các tệp lớn | Tải toàn bộ sơ đồ một lúc | Sử dụng `DiagramLoadOptions.setLoadMode(LoadMode.Stream)` để xử lý các trang theo thứ tự. |
+| Watermark không hiển thị | Watermark được đặt phía sau nội dung hiện có | Gọi `watermarker.setWatermarkPosition(Position.Foreground)` trước khi lưu. |
+
+## Câu hỏi thường gặp
+
+**Q: Tôi có thể thay thế hình ảnh trong sơ đồ được bảo vệ bằng mật khẩu không?**
+A: Có. Cung cấp mật khẩu cho `DiagramLoadOptions` khi tạo `Watermarker`.
+
+**Q: Thư viện có hoạt động với các tệp .drawio (XML) không?**
+A: Hoàn toàn – GroupDocs.Watermark hỗ trợ định dạng Draw.io XML và xem mỗi node như một hình dạng.
+
+**Q: Tôi có thể xử lý bao nhiêu sơ đồ đồng thời?**
+A: Thư viện an toàn với đa luồng cho các thao tác chỉ đọc; đối với các thao tác ghi, hạn chế đồng thời theo số lõi CPU để tránh tranh chấp handle tệp.
+
+**Q: Có giới hạn kích thước hình ảnh không?**
+A: Hình ảnh lên tới 100 MB được hỗ trợ; các tệp lớn hơn nên được thu nhỏ trước để giảm mức sử dụng bộ nhớ.
+
+**Q: Các tùy chọn cấp phép nào có sẵn?**
+A: Bạn có thể bắt đầu với bản dùng thử miễn phí 30 ngày; sử dụng trong môi trường sản xuất yêu cầu giấy phép trả phí, có thể mua tại cửa hàng GroupDocs.

+# Bảo vệ các sơ đồ sở hữu trí tuệ với GroupDocs.Watermark
+
+Việc bảo vệ các sơ đồ sở hữu trí tuệ là một bước quan trọng đối với bất kỳ tổ chức nào chia sẻ tài sản thiết kế, lưu đồ hoặc bản vẽ kiến trúc. Với GroupDocs.Watermark cho Java, bạn có thể tải các tệp sơ đồ (như `.vsdx`), phát hiện các watermark hình ảnh, tìm kiếm watermark văn bản và an toàn loại bỏ chúng mà không làm hỏng bản vẽ gốc. Hướng dẫn này sẽ đưa bạn qua toàn bộ quy trình — từ thiết lập môi trường đến xử lý hàng loạt các thư viện sơ đồ lớn — để bạn có thể tích hợp bảo vệ IP mạnh mẽ trực tiếp vào các ứng dụng Java của mình.
+
+## Câu trả lời nhanh
+- **Thư viện nào xử lý watermark cho sơ đồ?** GroupDocs.Watermark for Java.
+- **Tôi có thể phát hiện watermark hình ảnh cũng như văn bản không?** Có, API cung cấp `ImageDctHashSearchCriteria` để phát hiện hình ảnh và `TextSearchCriteria` cho văn bản.
+- **Tôi có cần giấy phép thương mại để chạy mã không?** Giấy phép dùng thử hoạt động cho phát triển; giấy phép trả phí cần thiết cho môi trường sản xuất.
+- **Có hỗ trợ xử lý hàng loạt không?** Chắc chắn — lặp qua một thư mục và áp dụng cùng logic watermark cho mỗi tệp.
+- **Bố cục sơ đồ gốc có giữ nguyên sau khi loại bỏ không?** Thư viện chỉ xóa các đối tượng watermark, giữ nguyên mọi hình dạng, kết nối và định dạng.
+
+## Sơ đồ sở hữu trí tuệ là gì?
+Sơ đồ sở hữu trí tuệ là các biểu diễn trực quan — như lưu đồ, mô hình UML, sơ đồ mạng, hoặc bản vẽ kiến trúc — chứa thông tin độc quyền thuộc về cá nhân hoặc tổ chức. Những sơ đồ này thường truyền tải quy trình, thiết kế hoặc chiến lược bí mật, khiến chúng trở thành tài sản có giá trị cần được bảo vệ khỏi việc sao chép, phân phối hoặc thay đổi trái phép. Bằng cách coi chúng là sở hữu trí tuệ, bạn có thể áp dụng các biện pháp pháp lý và kỹ thuật, bao gồm watermark, để duy trì kiểm soát việc sử dụng và lan truyền chúng.
+
+## Tại sao nên sử dụng GroupDocs.Watermark cho Java?
+GroupDocs.Watermark hỗ trợ **hơn 50 định dạng đầu vào và đầu ra** (bao gồm `.vsdx`, `.vdx`, `.vsx`) và có thể xử lý các sơ đồ hàng trăm trang mà không cần tải toàn bộ tệp vào bộ nhớ, giảm tiêu thụ RAM lên tới **70 %** so với các phương pháp đọc luồng tệp thuần. API cũng cung cấp so sánh ảnh‑hash không cần OCR, cho phép thực hiện các thao tác `detect image watermark` một cách đáng tin cậy trong dưới **200 ms** cho mỗi sơ đồ trên máy chủ 2.5 GHz tiêu chuẩn.
+
+## Yêu cầu trước
+Trước khi bắt đầu, hãy chắc chắn rằng bạn đã có:
+
+1. **Java Development Kit (JDK) 8+** – mã sử dụng các API chuẩn của Java 8.
+2. **IDE** – IntelliJ IDEA, Eclipse, hoặc bất kỳ trình soạn thảo nào bạn thích.
+3. **GroupDocs.Watermark for Java** – có thể qua Maven hoặc tải JAR thủ công.
+
+### Thư viện và phụ thuộc cần thiết
+Bạn có thể thêm thư viện qua Maven hoặc tải JAR trực tiếp.
+
+#### Cấu hình Maven
+Thêm các mục repository và dependency vào tệp `pom.xml` của bạn:
+
+```xml
+
+
+ repository.groupdocs.com
+ GroupDocs Repository
+ https://releases.groupdocs.com/watermark/java/
+
+
+
+
+
+ com.groupdocs
+ groupdocs-watermark
+ 24.11
+
+
+```
+
+#### Tải trực tiếp
+Nếu bạn muốn cài đặt thủ công, tải bản phát hành mới nhất từ [GroupDocs.Watermark for Java releases](https://releases.groupdocs.com/watermark/java/).
+
+### Cách lấy giấy phép
+- **Dùng thử miễn phí:** Lý tưởng để đánh giá khả năng của API.
+- **Giấy phép tạm thời:** Dùng cho việc thử nghiệm ngắn hạn mà không bị giới hạn tính năng.
+- **Mua bản quyền:** Cần cho triển khai sản xuất và để mở khóa các định dạng cao cấp.
+
+## Cách khởi tạo Watermarker?
+Tạo một thể hiện `Watermarker` là bước đầu tiên trong bất kỳ quy trình watermark nào. Lớp `Watermarker` tải tệp sơ đồ vào bộ nhớ và cung cấp các phương thức để tìm kiếm, thêm và loại bỏ watermark. Bằng cách truyền đường dẫn sơ đồ và tùy chọn `DiagramLoadOptions` (nếu có), bạn nhận được một đối tượng làm trung tâm cho tất cả các thao tác tiếp theo, đảm bảo việc xử lý tài liệu nhất quán trong suốt quá trình.
+
+```java
+Watermarker watermarker = new Watermarker(inputFilePath, loadOptions);
+```
+
+## Cách tải tài liệu sơ đồ?
+Sử dụng `DiagramLoadOptions` khi tải sơ đồ cho phép bạn kiểm soát chi tiết cách tệp được phân tích. `DiagramLoadOptions` cho phép bạn chỉ tải các trang hiển thị, quyết định có giữ lại các lớp ẩn hay không, và cách xử lý phông chữ nhúng. Điều chỉnh các tùy chọn này có thể cải thiện đáng kể hiệu năng cho các sơ đồ lớn và đảm bảo chỉ các phần cần thiết của tệp được xử lý, giảm sử dụng bộ nhớ và tăng tốc độ phát hiện watermark.
+
+```java
+DiagramLoadOptions loadOptions = new DiagramLoadOptions();
+loadOptions.setLoadHiddenLayers(false);
+Watermarker watermarker = new Watermarker("sample.vsdx", loadOptions);
+```
+
+## Cách phát hiện watermark hình ảnh trong sơ đồ?
+Phát hiện watermark hình ảnh dựa trên lớp `ImageDctHashSearchCriteria`, lớp này tính toán một hàm băm nhận thức của ảnh tham chiếu và so sánh với mọi ảnh nhúng trong sơ đồ. Phương pháp này nhanh và chịu được các biến đổi nhỏ về hình ảnh, cho phép bạn xác định logo hoặc các watermark đồ họa ngay cả khi chúng đã được thay đổi kích thước hoặc chỉnh sửa nhẹ. Bằng cách cấu hình ngưỡng tương đồng, bạn có thể cân bằng độ nhạy phát hiện với các kết quả dương tính giả.
+
+```java
+ImageDctHashSearchCriteria criteria = new ImageDctHashSearchCriteria("logo.png");
+PossibleWatermarkCollection watermarks = watermarker.search(criteria);
+```
+
+## Cách tìm kiếm watermark văn bản?
+Tìm kiếm watermark văn bản sử dụng lớp `TextSearchCriteria`. Lớp này quét tất cả các lớp văn bản trong sơ đồ, bao gồm cả những văn bản nằm trong hình dạng, kết nối và nhóm, và trả về bất kỳ kết quả nào chứa chuỗi hoặc mẫu đã chỉ định. Việc tìm kiếm mặc định không phân biệt chữ hoa/thường và có thể tinh chỉnh bằng biểu thức chính quy, cho phép bạn xác định các watermark có thể bị xoay, ẩn một phần, hoặc nhúng trong cấu trúc sơ đồ phức tạp.
+
+```java
+TextSearchCriteria textCriteria = new TextSearchCriteria("Confidential");
+PossibleWatermarkCollection textWatermarks = watermarker.search(textCriteria);
+```
+
+## Cách loại bỏ watermark khỏi sơ đồ?
+Việc loại bỏ watermark được thực hiện bằng cách gọi phương thức `clear()` trên mỗi đối tượng `Watermark` trả về từ thao tác tìm kiếm. Phương thức `clear()` chỉ xóa các yếu tố watermark trực quan trong khi để nguyên các đối tượng sơ đồ nền — như hình dạng, kết nối và định dạng — không bị ảnh hưởng. Sau khi xóa, bạn lưu tài liệu bằng phương thức `save`, tạo ra một phiên bản sạch của sơ đồ vẫn giữ nguyên bố cục và chức năng gốc.
+
+```java
+for (Watermark wm : watermarks) {
+ wm.clear();
+}
+watermarker.save("cleaned.vsdx");
+```
+
+## Ứng dụng thực tiễn
+- **Tích hợp phần mềm doanh nghiệp:** Nhúng xác thực watermark vào hệ thống quản lý tài liệu để tự động thực thi chính sách IP.
+- **Hệ thống quản lý nội dung (CMS):** Quét các sơ đồ người dùng tải lên để phát hiện logo không được phép trước khi công bố.
+- **Xử lý tài liệu pháp lý:** Phát hiện và loại bỏ watermark bí mật khi chuẩn bị các gói bằng chứng.
+
+## Những lỗi thường gặp và khắc phục
+- **Ngoại lệ thiếu giấy phép:** Đảm bảo tệp trial hoặc bản trả phí được tham chiếu đúng qua `License.setLicense("license_path")`.
+- **Sơ đồ lớn chậm:** Bật `loadOptions.setLoadHiddenLayers(false)` và cân nhắc xử lý sơ đồ bằng các luồng song song.
+- **Kết quả dương tính giả cho ảnh:** Điều chỉnh độ chịu lỗi DCT hash bằng `criteria.setSimilarityThreshold(0.85)` để giảm các khớp ngẫu nhiên.
+
+## Câu hỏi thường gặp
+
+**Q: Tôi có thể tìm kiếm cả watermark văn bản và hình ảnh trong một lần gọi không?**
+A: Có, kết hợp các tiêu chí bằng `OrSearchCriteria` (ví dụ, `new OrSearchCriteria(textCriteria, imageCriteria)`) để lấy cả hai loại cùng lúc.
+
+**Q: Việc loại bỏ watermark có làm hỏng bố cục sơ đồ không?**
+A: Không. Thư viện tách riêng các đối tượng watermark, vì vậy các hình dạng, kết nối và định dạng vẫn giữ nguyên sau khi gọi `clear()`.
+
+**Q: Các định dạng sơ đồ nào được hỗ trợ?**
+A: GroupDocs.Watermark hỗ trợ `.vsdx`, `.vdx`, `.vsx` và một số định dạng Visio cũ, bao phủ hơn **30** loại sơ đồ.
+
+**Q: Làm sao xử lý hàng ngàn sơ đồ một cách hiệu quả?**
+A: Sử dụng `ExecutorService` của Java để chạy phát hiện/loại bỏ watermark trong các batch song song, và tái sử dụng một đối tượng cấu hình `Watermarker` duy nhất để giảm chi phí khởi tạo.
+
+**Q: Có thể tích hợp tính năng này vào quy trình CI/CD không?**
+A: Hoàn toàn có thể. Thêm các đoạn mã Java vào script build (Maven/Gradle) và chạy chúng như một bước kiểm tra trước khi triển khai để đảm bảo không có watermark bị cấm xuất hiện.
