Cut out the border, paste it into a new layer, and hide the new layer. 4). In the base layer, invert the selection, using Select > Invert. 5). Choose your color, and fill the desired rectangle. 6) Unhide the new layer, and Merge the layers together. 7) flatten image. ns ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

The steps I outlined work for your attached image of two white rectangles surrounded by black lines. Depending upon the details of the actual images with which you are working, you might be able to make it work with more or fewer steps, but the principle should still hold. ns ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
