ICC profile graphs

During the recent days I improved the file dialog preview of ICC Examin. As a result I created a new Oyranos tool called oyranos-profile-graph, which can be found in git. It provides a simple icon and can potentially be used in tools like Synnefo or KolorManager‘s info tab.

There exist some graphing tools like ppmcie to generate a nice triangle inside a CIE*xy horse shoe.

But as ICC Examin sticks on CIE*Lab, I think it is more appropriate to use the CIE*a*b projection instead. Both are available by oyranos-profile-graph. The graphical output of the tool is really simple, beside using Cairo for antialiased curves. Below are the 2D graphs for sRGB.icc LStar-RGB.icc ProPhoto-RGB.icc ISOcoated_v2_bas.ICC ISOuncoatedyellowish_bas.ICC profiles. The first graph is CIE*ab and the second shows the same saturation lines in CIE*xy.

  1. I don’t understand half of this but man is good to see professional stuff being coded for KDE! Finally something more important then f**ing plasmoids :) Keep rocking!
