I’m trying to load a geo-referenced .bmp file. You can get the file here: https://www.dropbox.com/s/lsfpamt97ciw2or/WholeEarth56.bmp?dl=0
I tried using NativeImageRasterLayer but no luck. In the future I might want to load jpgs as layers as well, and geo tiffs. What’s the correct way to do this?
Hi Dan_Weaver,
We created one sample to show you how to image file. Please refer below attachment.
NativeImageRasterLayer needs a world file which contains image extent info. If the world file doesn’t exist, you need to apply a image extent to layer.
If you have any questions, please feel free to contact us.

Hey thanks for the response!
Your app works fine, I can’t get it working correctly in my own solution though. It seems to concern projections.
All my shapefiles that I am loading on the map are adhering to the following projection:
Proj4Projection proj4Projection = new Proj4Projection();
proj4Projection.InternalProjectionParametersString = Proj4Projection.GetEpsgParametersString(4326);
proj4Projection.ExternalProjectionParametersString = Proj4Projection.GetEpsgParametersString(3857);
So the internal projection is a cartesian projection, and the external is a mercator type projection. My mapunit is also in meters.
Attached is a zip file containing the main shape file I’m using.

Hi Dan,
It also works well with your data.
Please try it and see whether it works for you.

Hey Ethan, I think you misunderstood. I don’t have problem loading the shapefiles. I do have a problem lining up the bitmap with the shapefiles. The bitmap gets all weird when I try projecting it to the same projection as my shapefiles. Also when I try setting the map in meters.
