I've been trying to use Paul Harrison's "Resynthesizer" plug-in and script, and it seems that since it was created and now (GIMP 2.4.6) something has changed, and the script seems to be broken. I don't know enough script/fu to debug it (yet?), but what it looks like it's doing is filling the target area with a texture synthesized from the very top of the image, which in my photos is usually sky. I achieved a very amusing demonstration of this by first inverting (top for bottom) the image, then applying the script to the same patch, and it was filled with the wooden deck that used to be at the bottom but is now at the top.
I'm actually trying to do useful work with this (create images of people for a borchure) by removing things like power lines from backgrounds. I know I can "clone" and "heal", but it (for my skill level) looks funky when I use them.
I think the actual texture synthesizer (version 0.13b) still works, but I'm guessing there is something funny in the scripts.
Any script gurus here who can look?
Thanks & happy trails,
