Hey Jay, The first thing I would try is obtaining a set of backgrounds with strongly saturated colors, like colored construction paper, to select background colors that are not present at the edge of the stamps themselves. Then I would turn on the Fuzzy Select a.k.a. "magic want" tool to select the background area by color - with the Tool Option tab open in the dock. Adjusting the Fuzzy Select tool's threshold (way up) might get you where you want to be in selecting the background, and all of it, so that when you fill the selection you will get all of the background with no "halo effect" or unacceptable degradation of the edge of the stamp itself. :o) Steve _______________________________________________ gimp-user-list mailing list firstname.lastname@example.org http://mail.gnome.org/mailman/listinfo/gimp-user-list
