PUT_PIXEL would be way too slow. Any ideas? Perhaps it makes more sense to reverse the direction here. That is, have load_gif only work on an area it allocates itself, and cache that. And then use PUT_PIXEL at the end to copy to the ximg... That should be portable, I think, without knowing anything about what the ximg really is. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
