Creates a picture fill symbol layer from a BitmapDrawable. Create a PictureFillSymbolLayer with image data. The image, if valid, is set as the image used to fill the containing polygon. The function throws if the image is null or empty. If the image is valid, the load status of the PictureFillSymbolLayer is set to LoadStatus.Loaded. This method invokes Bitmap.compress and may be long running.
