How shoud that bright line of white pixel hinder flattening? I don't have enough
experience with ImageMagick. I see your point, but I don't realize where this
bright line came from in the first place. The partial images came directly from
radiosity3a.pov rendered scene, I made no intervention as to insert a white
line.

Is there a way to cut images and later reassemble stripes pf columns with
convert or composite -adjoin?

Rgds,
Marvin
