Any suggestions are welcome. I think gdk_draw_rgb_image_dithalign() is about as fast as you can get while staying within the world of gdk. I avoid a copy by having my non-standard format be 24-bit RGB and drawing directly from that, but that's it I think. I don't know if gdk_draw_rgb_image_dithalign() uses the XVideo extension, but I imagine not. Of course using that ties you to X. Maybe Cairo with a GL backend would be quicker? Though it'll be a while before that is a common target :) John _______________________________________________ gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
