: Funny you should mention that, we have been telling Greg that we need to have
: variable depth pixmaps for a while now.
:
: It wouldn't be *too* messy, the only thing we would need is a set of really
: good conversion blit routines (especially to and from a depth of 1 (for
: bitmaps)). If anyone has any that they have been working on and want to
: donate to the cause, we can write all the supporting code pretty quickly.
It might be worth digging around in Imlib2 - there are routines in there to
do all sorts of image depth conversions, I would elaborate futher but I dont
have a copy to hand. But I know Carsten (raster) has got all sorts of *fast*
routines in there that may be a good base point. I will also talk to raster
as I know he has some stuff in the pipeline,
regards,
Chris
