What to do with alpha blending?
Posted: Jan 21, 2005 @ 7:46amSeems like many people have been implementing their own support for per-pixel alpha blending, long-wanted in PF.
What operations with alpha-aware surfaces did you have to add, besides Blit? How did it affect the underlying design (surface format, etc) ?
What about the ability to blit one alpha-aware surface to another alpha-aware surface - and get alpha-aware results? It could be useful for pre-rendering composite pictures like a super-hero carrying a pile of weapons he's collected so far ( imagine
)
Thanks
