Sure enough, blackcolor is 0, thanks. I did XSetForeground to whitecolor and it works fine. Now I can press onward and wow the world with my super-duper animation. :) The last time I tried to use xor it was for signing photographs with an SVG signature, I found a wide white line with a thin black line on top worked better. I don't remember what color I was trying to xor on but the backgrounds varied all over the place. _______________________________________________ xorg@lists.x.org: X.Org support Archives: http://lists.freedesktop.org/archives/xorg Info: https://lists.x.org/mailman/listinfo/xorg Your subscription address: %(user_address)s
