> It seems that direct screen access is slow on some devices. My application uses direct screen access to gain some speed especially on old devices. Since it's using only 2 bits per pixel (4 level grey) I have not examined other modes.
IIRC an old hirez Sony Cli� was not only very slow (the screen got updated only every second), it additionally has its bits "the other way around" so that the MSBs of each byte hold the right pixel, not the left as usual. Devices I found really slow are Tungsten W, Samsung i500, and Xplore G18. At least with OS5 the application does the mentioned double buffering and bitmap copy with the OS. Since this is ARM code, it so much faster than emulated 68K direct access ;-) Bodo -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
