Attached is the new widget I've just added to gnome-color-manager git master. It allows us to show the user a preview of the gamut range of the profile in a graphical way, much like OSX does. You should be able to see the lightly shaded section. At the moment I've hardcoded the CIE REC 709 x-y values, but of course it's easy to change when put into GcmPrefs. So, the point of this email: I wanted to get the CIE x and y coordinates (or XYZ of course) of the three primary illuminants and the x and y coordinates of the white point from the device ICC profile. Is there an easy way to extract these end-point values from the ICC file? I guess mediaWhitePointTag is the latter half of the problem, but I'm not sure how to deal with the LUT values. Ideas welcome. Thanks. Richard.
