When I load a jpeg file with v100.3, it doesn't seem to be honoring the world (.jgw) file.
I created the jpeg by exporting from arcmap. Both Pro and arcmap can load the layer as expected.
However, when I
var rLayer = new RasterLayer("myfile.jpg");
rLayer.FullExtent.SpatialReference is null after loading.
rLayer.FullExtent.width is based on pixels, not world coordinates.
I would try to read the world file myself and assign it an extent, but don't see a setter for fullextent.
I would like a setter (like that of arcobjects ILayer.Spatialreference).
