I have a MapImageLayer that consists of only one MapImage at a time. I would like to sample the current pixel beneath the mouse on hover and read it's RGB. I have seen some stuff on this regarding a canvas, however I'm not sure how to make a map layer a canvas.
OR as an alternative, is there another way to display a geotiff without using a RasterLayer as I do not have access to an ImageService? Currently I'm displaying a rainfall image as a georeferenced .png with a MapImageLayer, and the whole idea is to be able to sample it. If I know the RGB, I at least know a range of values it could be, which is better than nothing.
