Internal error: The raster layer does not have a spatial reference.

Attempting to load a set of PNG raster files but seeing the following error from the LayerViewStateChanged event.

Internal error: The raster layer does not have a spatial reference.

I don't see any way to set the spatial reference on the RasterLayer as the property only has a getter. Also, I have world files that are in the same directory as the png files.

private async Task LoadMap() { // create map Map myMap = new Map(SpatialReference.Create(3857)); myMap.Basemap = new Basemap(BasemapStyle.ArcGISOceansBase); MyMapView.Map = myMap; MyMapView.LayerViewStateChanged += MyMapView_LayerViewStateChanged; // Get the file name string filepath = GetFilesPath(); var files = Directory.GetFiles(filepath, "*.png"); foreach (var file in files) { // Load the raster file Raster myRasterFile = new Raster(file); // Create the layer RasterLayer myRasterLayer = new RasterLayer(myRasterFile); // Add the layer to the map myMap.OperationalLayers.Add(myRasterLayer); try { // Wait for the layer to load await myRasterLayer.LoadAsync(); // Set the viewpoint await MyMapView.SetViewpointGeometryAsync(myRasterLayer.FullExtent); } catch (Exception e) { MessageBox.Show(e.ToString(), "Error"); } } }
