Another way is to use enblend 4.1.4. Yes, masking them out would work, but it's a lot of work. I've never had issues with enblend 4.1.4. > b) ...

I went looking for the enblend man page, but drew a blank. All I have is the --help. You're talking about one of these, right? --primary-seam-generator=graph-cut --primary-seam-generator=nearest-feature-transform I may try this.

So I didn't. Yes, I had difficulty there too. But it looks as if it might be worth it. None of these issues has shown up with 4.1.4. What was wrong in that version that required changes in the algorithm? Greg -- Sent from my desktop computer. Finger [email protected] for PGP public key.
