thanks for clarifying, - Leo Reiter Paul Brook wrote:
Unfortunately X11 will not allow you to force a certain color order in 24-bit mode. You can tell it to force byte-order but this only affects 16-bit blits - it's ignored for 24-bit since the individual components of the 24-bit blits, even if packed into 32-bits, are still 8-bits long. That's what the color masks are for. There is no efficient way to do this at the server level that I can see. If you find a better way (within the current scope of the VGA architecture), I'd be glad to try to implement it. I was just sharing something that was useful to me.It should be possible to select between different 24-bit packings the same way different bit depths are handled.Paul
