GetBuffer on iPAQ 3870

by **v0101** » Mar 31, 2005 @ 4:11am

I've been using GetBuffer/ReleaseBuffer to do some custom drawing on the BackBuffer. Works great, except I just tried my program on an iPAQ 3870. It runs fine, but whenever my program tries to do it's custom drawing it crashes. This only happens on an iPAQ 3870. Any ideas? I'm using GapiDraw 3.5c without PocketHAL. Thanks.

The 3870 uses a 90 degrees rotated display (as compared to -90 on the IPAQ 3600). Thus xPitch and yPitch are pretty strange.

Check the plasma demo for some references...

Is it possible to create my own off-screen surface that's not rotated and then blit it to the backbuffer?
