Thanks! That worked. The size and aspect ratio of the rectified quadrilateral isn't always close to what I want it to be, though. Is there a way to specify this before I do the perspective transform, or do I just need to do it in 2 steps (correct perspective, and then re-size)? _______________________________________________ gimp-user-list mailing list gimp-user-list@gnome.org https://mail.gnome.org/mailman/listinfo/gimp-user-list
