From 902936987ae9910aad7734551e7ab8a347251c37 Mon Sep 17 00:00:00 2001 From: Masashi Katsumata Date: Sat, 7 Nov 2026 05:40:54 -0800 Subject: [PATCH 1/3] Draw large polygon sets as raster tiles (PolygonTiler) The polygon controller gets a PolygonTiler, whose tiles are shown through the raster layer path the marker tiles use (upsert / removeById, outside the app's RasterLayer composition). Tiled polygons stay registered for taps and give the map SDK nothing. --- .../mapconductor/here/HereMapViewController.kt | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) diff --git a/src/main/java/com/mapconductor/here/HereMapViewController.kt b/src/main/java/com/mapconductor/here/HereMapViewController.kt index 8150c0d..1e0b58c 100644 --- a/src/main/java/com/mapconductor/here/HereMapViewController.kt +++ b/src/main/java/com/mapconductor/here/HereMapViewController.kt @@ -1,5 +1,8 @@ package com.mapconductor.here +import com.mapconductor.core.polygon.POLYGON_TILE_LAYER_ID +import com.mapconductor.core.polygon.PolygonTiler +import com.mapconductor.core.polygon.polygonTileRasterLayerState import HereMapDesignTypeChangeHandler import HereMapViewControllerInterface import com.here.sdk.core.Point2D @@ -167,6 +170,19 @@ class HereMapViewController( } }, ) + + // Many polygons are drawn as raster tiles, shown through the same RasterLayer + // controller as the marker tiles (upsert / removeById, never the app's layers). + polygonController.tiler = + PolygonTiler().apply { + onTemplate = { template, tileSize -> + if (template != null) { + rasterLayerController.upsert(polygonTileRasterLayerState(template, tileSize)) + } else { + rasterLayerController.removeById(POLYGON_TILE_LAYER_ID) + } + } + } } override fun moveCamera(position: MapCameraPosition) = handleMoveCamera(position) From 1923dc1dc7cea1903379fda3f951b521d150b037 Mon Sep 17 00:00:00 2001 From: Masashi Katsumata Date: Mon, 9 Nov 2026 06:51:43 -0800 Subject: [PATCH 2/3] Stack the polygon tiles at the bottom of the polygon band With develop's OverlayStacking, a raster layer goes in the raster band, under ground images.
