I know that drawing surfaces dont support 8-bit alpha channels but is it possible to paint to the 1-bit alpha?
in a 16-bit game you would just paint (255,0,255) to the sprite to make it transparent. but in a 32-bit that doesnt work. is there an alternative?
It should work, I do it all the time in my game. Try using COLOR_TRANSPARENT instead of RGB(255, 0, 255), perhaps the magic pink behavior changed when RawDraw was replaced with DrawingSurface functions.
yup that works.. thanks
