> I want to display a image using selectabledrawwidget. The image hold geographic coordinate (GTCP code 100). When I try to add map grid or outline on the display, I should set a mapcoord for the display. But as I know, the mapcoord definition does not support geographic projection. So anyone know how to process it? or is there any other object can finish the work?

I added the Geographic "projection" to the MapCoord object for you this
morning. You can find it here:
