- Is there a ROP code to accomplish a transparent blit in 256 color modes.
-
- In other words, if I have an off screen image with a black background
- (index 0) and I want to bitblt it on top of an existing 256 color
- scene, how do I allow only the non-black portion of the off screen image
- to be drawn?
-
- thanks, Tommie Daniel daniel@unm.edu
