Fill Symbol Layer
A symbol layer that fills polygon geometry with an image. The specified image fills the layer's polygon if it's the only symbol layer in a MultilayerPolygonSymbol. If a single image doesn't completely fill the geometry, it is tiled to complete the fill.
This layer can also represent the Web Scene specification's Icon3DSymbolLayers. PictureFillSymbolLayer represents IconSymbol3DLayers that contain pictures and VectorMarkerSymbolLayer represents Icon3DSymbolLayers that are primitives or vector paths.
The image held by a picture fill symbol layer. The BitmapDrawable held by the given PictureFillSymbolLayer. Setting the image visually changes the image that makes up the fill pattern. If the image is valid and non-empty, this function sets the image and sets the symbol layer's load status to LoadStatus.Loaded. You cannot set an image on a PictureFillSymbolLayer that has already loaded.
The tint color of a picture fill symbol layer. The tint color is applied to the entire image by multiplying each RGB color channel in the image by the corresponding color channel of the tint color. The default tint color is white with 100% opacity, i.e. RGBA(255, 255, 255, 255), which leaves the image with its native colors. A white tint color with opacity less than 100% tints the image white, with the reduced opacity respected.
