How to compute image gamut from Lab tiff file by "tiffgamut"?


This should just work - but there is a bug. I'll fix it for
the next release.


How to make device link from Lab space to destination printer space?


You can't using collink. Normally you wouldn't want/need to,
because the device profile itself has this functionality,
so there is nothing to do.


I've understood only how to convert Lab tiff to other space by cctiff:
"cctiff -v -or sRGB.icc -p -d"sRGB.icc" HK_LAB.tif HK_sRGB.tif".
But I do not understand how to do any other work with tiff. Unfortunately I 
have no
CIELab.icc file. And I don't want to convert tiff to other intermediate space.


Attached is a small profile I made called "lab2lab" that may
be useful, but it shouldn't be needed using cctiff, since cctiff
will input and/or output Lab, depending on the profile sequence.
