Jeff: First thing to understand is if you are looking for numerical information or for graphical info. * If you are seeking gamut volume info, my suggested way to go is to use Jan Morovic's public gamut mapping algorithm library. Find it in here: www.colour.org/tc8-03/*pgma *But you have some work to do there, since it is just a framework, and you need to implement the calculations.
* If you are looking for visual info, be warned that the gamut is 3D and the chromaticity diagram is only 2D. Having said this, I would support John's suggestion of taking several slices and applying the profile to those slices/images... You can find a nice set of images in BruceLindbloom's site: http://www.brucelindbloom.com/downloads/ProfileEvaluation.zip These are 11 images of the LAB space sliced in 10L* steps. If you use Marti's tifficc as in tifficc -i*lab -t3 -g -o<your_profile> -p*srgb lab_xxx.tif out.tif you will obtain an image with the gamut of your_profile at slice "xxx", for the abscol rendering intent (use -t to select your desired intent). Repeat that for the 11 images, and you'll have your visual info. Hope this helps, Ignacio PS: I am assuming those images encoded as *lab, so we do not need to use the tiff8lab profile... > > Hi friends; I hope everyone's doing well.
