I am using forelayer and drawer (imagelib.dll) to drawimage1. The transparent color on drawimage1 works fine and the background can be view through the transparent color.
However, when I draw two images, the second image overlaps the first image, then I find the first image is covered by the second image and the transparent color.
I thought it is due to I can use only onle forelayer. Any walkaround to solve that?
