Ah. I thought I recalled it doing edge detection, but I haven't played with it (like about 90% of the amazing functionality :-) Are you sure, or have you checked with the Magick support folks?
I have joined pngs, but I knew the edge was exactly at the limit of the png, there was no overlapping.
I can not imagine how to do it with ImageMagic with unknown overlap.

You don't have to; you select from your pile all of the pictures that touch each other and it figures out how they overlap and comes up with one final [huge] image. Way better than trying to do so by hand, too.
Good luck! :-)
Ok, I may try. Each of the three photos are about 60 Megs, very big for a tiny procesor.
If it's only one image I'd simply do it with the Gimp, easy and probably faster than searching for a software, install, try... Open one image in the gimp. Enlarge canvas to the full end size or larger. Load the other images as layers. Show only first layer and an adjoining one. Make the adjoining one semi-transparent and move it around until it fits. Make it nontrasparent again. Continue with the remaining layers. Save as jpg, png or whatever (or as xcf if you want to preserve layers) Done. -- Daniel Bauer photographer Basel Málaga Twitter: @Marsfotografo (often explicit nudes) https://www.patreon.com/danielbauer https://www.daniel-bauer.com (nudes)
