- Subject: fast 32 bit screen copy
- Lines: 15

-
- Does anyone have suggestions on how to do the following:
-
- Using the Apple graphics accelerator card and a IIfx, a friend needs to
- transfer a 450x450 32 bit image from memory to the screen in 50 msec or
- less. Right now he's at about 100 msec using offscreen gworlds as
- described in apple tech note 120.
-
- Are there faster techniques for bitmap transfers, or is there a graphics
- card available that could speed things up?
-
- Thanks,
- Rob
