profile file: The edit box accepts one of the following:
- a file name of a ICC or dcamprof JSON profile found in the directory specified in cms.profilepath,
- a built-in profile, one of the following is valid:
- "srgb", "wide", "adobe", "prophoto", "identity" will invoke a dcraw D65 linear profile, useful for working spaces;
- "aces2065-1-v4-g10", "adobergb-v4-g10", "bt709-v4-g10", "prophoto-v4-g10", "rec2020-v4-g10", "srgb-v4-g10",
"srgb-v2-g22", "srgb-output" will invoke a binary ICC profile embedded in rawproc of the specified version and gamma.
srgb-v2-g22" and "srgb-output" are the same file.
- a set of nine comma-separated integers or floats, representing the dcraw color primaries for a particular camera.
Integer sets follow the dcraw convention; for example,
the Nikon D7000 primaries are 8198,-2239,-724,-4871,12389,2798,-1043,2050,7181. Float sets follow the Adobe Digital
Negative (DNG) convention for a D65 ColorMatrix* tag; for example, for an Apple IPhone 8 DNG, 0.829948 -0.273887 -0.097103 -0.572908 1.3635 0.170901 -0.0863387 0.136364 0.536422. These sets can also be specified as a
JSON array, e.g., [ 8198, -2239, -724, -4871, 12389, 2798, -1043, 2050, 7181 ]
which is then used either to transform the image from the
previous colorspace to the new one (convert) or to attach the profile to the image as a representation
of its current colorspace (assign). Either a full file path name can be specified, or just a filename,
in which case the cms.profilepath property is consulted for the path.
The "Select" button opens a file selector on the directory specified in cms.profilepath. If a profile is selected
from this directory, the command will include only the filename; if the selector is switched to a different directory, the command
will include the full path of the profile.
The "Select (cwd) button opens a file selector on the current working directory. If a profile is selected
from this directory, the command will include only the filename; if the selector is switched to a different directory, the command
will include the full path of the profile.
For either of the above Select buttons, a filename without a path will be searched for in first 1) the current working directory, then 2) the directory specified in the cms.profilpath property. So, if an identically-named profile is present in both the cwd and cms.profilepath, the cwd profile will be selected.
The Rendering Intent selection allows one to choose the algorithm used to handle conversion of
out-of-gamut colors. Note that not all profiles allow use of all rendering intents; the LittleCMS
documentation should be consulted for guidance on an informed selection.
