By design, ICC gamut mapping is optimised to produce uniform acceptable
mappings for printing any image in a magazine. Thus if you crop an image,
the colors printed for the crop are always the same as those found in the
Klaus Karcher made a droplet called GAMAPICC that did image-optimised gamut
mapping. You can find it here - if the semantics of Argyll command lines
haven't changed too much, it might even still work, otherwise you can dig
out an old version of Argyll.

Now you say "and so makes available the
relevant information to collink". This relevant information, isn't it the
gamut we extracted using tiffgamut?
The first quote says, at least to me, the source gamut is coming ... from
the image (via tiffgamut) rather than the colorspace. So if we supply an
image gamut to collink, what does collink do with this gamut?
Uses it as the source gamut that (together with the destination gamut)
determines the gamut mapping.
I assumed collink was using this image gamut we extracted via tiffgamut
instead or "rather" than the colorspace gamut.
