Hem, by the way,
Wouldn't we need a [pix_rgba] in the chain to make sure we can use [pix_alpha] on them ? I think this is useful when it's either GIF files or MPEGs. Am I right ?

hi
i attached a patch, that is used to 'alphablend' from one to another picture. it is working though, but the cpu-load raises to 100% and it looks quite 'ruckelig' (not constantly flowing). i tried it on different machines with the same result. then i tried it with a better gfx-card, that supports opengl (Quadro FX 330), on a P4 2.66GHz (winxp). it looks better, but my patch still uses 100% cpu. i'm quite a gem-newbie and don't know much about opengl, but i assume that my patch is not optimized and there is still much calculated by cpu instead of gpu. last week i saw a screensaver-slideshow on an old ibook, that looked very nice. this let me hope there is still a chance, that i can realize the same with Gem on hardware that is up-to-date.
thanks for any help
roman
