I'm not looking at the code, so my recollection could be wrong, (or just plain out of date), but I don't think that pixman has code to rasterize "aliased" to an A8 buffer. It simply rasterizes based on the depth of the target mask buffer. So I think you'd have to write some new code to implement what you want here. -Carl
