This source is public domain!
This package contains some sources and a demo program.
The function is build up like a librray function and should be called as one.
Features of DrawImageTrans() (the new function):
- Compatible with intuition.library/DrawImage() (could be patched ;-)
- Imagedata can be in FAST_MEM
- Should work on any system and any graphics card.
Program has not been tested with graphics card. Please report bugs. You are
free to optimize and edit the source. It would be nice to receive changes
though.
If you use this source in your programs, please state original author of this
source somewhere.. well, it would be nice, but it's not required.
SUGGESTIONS:
You could make this routine sensitive to current DrawMode. F.ex: if drawmode
is JAM0 the image will be transperant, in other cases the function will act
like normal DrawImage() just that you keep the feature with imagedata in
FAST_MEM. I'll perhaps implement this feature myself in future.
Enjoy!
