But only as far as I say "create new layer/image with white background"... Or, wait, are you suggesting that "filling" is an operation known to GEGL, so a SolidFilledLayer will just change it's fill_color when it get's filled again? After all, this optimization does not work any more if I fill an arbitrary selection... Bye, Tino. -- * LINUX - Where do you want to be tomorrow? * http://www.tu-chemnitz.de/linux/tag/
