Hi Patrick !
Before new 3.0.2 version, ColorThink Pro was unable to plot right 2D xyY gamut for large gamut color spaces. For instance, ProPhoto RGB plot was NOT un triangle but a strange figure, a pseudo-triangle with exotic curved sides. Remember my old post [one.imports.literateforums.com/t/wrong-2d-plot-of-prophoto-rgb-with-colorthink-pro/745/1)
Now, with 3.0.2, 2D xyY plot for eciRGB or eciRGB_v2 are also wrong ! I mean that they are no more triangles… I also tested Adobe RGB (1998) plot which is a perfect regular triangle (by luck ?).
So, this old bug is not only still alive but is now growing…
Do I make a mistake ? Any explanation ?
