Add text to image support to AP #44405
Conversation
Changes SummaryThis PR extends the Advanced Paste module to support text-to-image generation capabilities alongside the existing chat completion functionality. It introduces a new PasteAIUsage enum to differentiate between ChatCompletion and TextToImage operations, adds UI components to display image results, and implements the necessary backend logic to handle both modalities through the Semantic Kernel framework. Type: feature Components Affected: AdvancedPaste Module - Core Service, SemanticKernelPasteProvider - AI Provider Implementation, OptionsViewModel - UI Logic, Settings UI - Advanced Paste Configuration, XAML UI Components - PromptBox and AdvancedPastePage, Settings Library - Provider Definition Files Changed
Architecture Impact
Risk Areas: Image data URI parsing: Uses simple Split(',')[1] which could fail if data URI format is unexpected - no validation of base64 format, Memory management: MemoryStream created in CustomFormatImageResult getter without explicit disposal using 'using' statement - potential resource leak on repeated image conversions, Network operations: HttpClient in ProcessTextToImageAsync is created fresh each call - should use shared HttpClient or factory pattern, Exception handling: Broad catch-all exceptions in image parsing/creation could mask underlying issues; errors are logged but silently fail to user, Settings persistence: New provider fields (Usage, ImageWidth, ImageHeight) must be properly serialized/deserialized - no validation shown for image dimensions, Semantic Kernel versioning: Uses experimental APIs (#pragma warning SKEXP0001, SKEXP0010) which may change in future versions Suggestions

🟠 HIGH - Split operation on string without bounds check
Agent: csharp
Category: bug
Description:
CustomFormatResult.Split(',')[1] is accessed without verifying the split produces at least 2 elements. If the data URI is malformed (missing comma), this will throw IndexOutOfRangeException.
Suggestion:
Use TrySplit or check array length before accessing index 1: var parts = CustomFormatResult.Split(','); if (parts.Length > 1) { var base64Data = parts[1]; }

🟠 HIGH - Split operation on string without bounds check

Description:
text.Split(',')[1] is accessed in PasteCustomAsync without verifying the split produces at least 2 elements. If a data URI is malformed, this will throw IndexOutOfRangeException.

Validate the split result: var parts = text.Split(','); if (parts.Length > 1) { var base64Data = parts[1]; } else { Logger.LogError(...); return; }

🟡 MEDIUM - Implicit default value in setter
Agent: csharp
Category: quality
Description:
ServiceType property setter silently changes null/whitespace to 'OpenAI' without documentation. This behavior should be documented.
Suggestion:
Add XML documentation to explain the default 'OpenAI' behavior, or consider making the default behavior more explicit.

🟡 MEDIUM - Magic number 1024 for image dimensions
Agent: csharp
Category: quality
Description:
Magic numbers 1024 used for default image width and height. Should be extracted to named constants for clarity and maintainability.
Suggestion:
Extract to constants: private const int DefaultImageWidth = 1024; private const int DefaultImageHeight = 1024;

🔵 LOW - Magic string comparisons for service types
Agent: csharp
Category: quality
Description:
String literals 'OpenAI' and 'AzureOpenAI' used in string comparisons instead of using the AIServiceType enum directly.
Suggestion:
Use AIServiceType enum comparison via ServiceTypeKind property or convert using ToAIServiceType() method first.
Why this matters: Using enums improves type safety and enables compile-time checking.
