Is there a way to load raster images with world files in the .Net Runtime SDK 100.0.0? I have a .tif image and a .tfw file with transformation information. The following code block works with GeoTiff files, but not with generic .tif images:
var raster = new Raster(System.IO.Path.Combine(GetStorageDirectory(), "redickville.tif"));
var rasterLayer = new RasterLayer(raster);
There are no runtime errors, but the raster does not appear. Is there a way to include the .tfw file in this process? Or the projection information?
If I use a 3rd party tool to create a GeoTiff file using the same files, that raster image can be loaded and displayed correctly using the above code. I attached the files I used.
The generic .tif lacks SpatialReference information. You can subscribe to LayerViewStateChanged event to find out errors related to loading/rendering of the layer. You can also see Supported Raster Formats.
MyMapView.LayerViewStateChanged += MyMapView_LayerViewStateChanged;
MyMapView.Map = new Map(Basemap.CreateImagery());
var path = @"C:\Temp\redickville.tif"; // fails on load, Layer.SpatialReference is not set
// var path = @"C:\Temp\redickville_GeoTiff.tif"; // renders fine
MyMapView.Map.OperationalLayers.Add(new RasterLayer(new Raster(path)));
private void MyMapView_LayerViewStateChanged(object sender, LayerViewStateChangedEventArgs e)
if (e.Layer is RasterLayer)
if (e.Layer.FullExtent != null)
if (e.LayerViewState.Error != null)
Currently the TIF file must be a GeoTIFF which includes the georeferencing information embedded within the TIFF file. You can use ArcGIS Pro to export as a TIFF with the GeoTIFF information.
I haven't tried it yet, but it looks like this is doable now (in SceneView only). If you look here:
You can see that in 100.8.0 there's now ImageFrame, which takes a RuntimeImage and either an Envelope or a Polygon. So you can load your regular image into a RuntimeImage and then put that in an ImageFrame with whatever corners you want, either as an Envelope rectangle or even a 4-point polygon. Then you can put that in an ImageOverlay and you should be all set.
I think you'd have to write your own translator from world file to Envelope or set of points, but I think that's a fairly standard conversion. But you should now be able to load your image with world file.
I want to do it too, and I haven't tried it yet, so let me know if it works.
