Subject: | Merging Backgrounds |
Hello,
Can anyone give me a simple (and fast) solution to the following,
I have a background set up on one screen and a foreground
set up on another, I need a way to somehow merge the foreground
graphics on top of the backround, kind of like DPaint's merge in front tool.
I would really like to copy the screen as a whole and not blit
individual sections of it onto the backround but it must be done
reasonably quickly. I initially thought that I might be able to use the scroll
command to copy the contents over from one screen to another but the
transparent parts of the foreground (colour 0) are not transparent so they
do not let the background show through them. Can I change the way scrolls
are performed to allow colour 0 to be transparent?
Any help would be great.
Jason.
