GNOME Color Manager has shown 2D CIE 1931 plots for a couple of years now, but as all color savvy people know, a gamut is a 3D object, and a 2D slice can be horribly inaccurate and misleading sometimes.
To fix this, I worked for a couple of hours at the weekend to produce a 3D gamut graph using clutter:
It’s then a simple case of clicking and dragging on the hull to rotate it. Long term, there will be a way to compare the different device gamuts, but I’ve not worked out a good way to show this in the UI.
To accomplish the new plot I’ve reused a lot of the math from icc_gamin, and a lot of the setup code from the viewer example program for mash, and also used a lot of the cleverness in clutter-gtk.
To play with the new toy, you’ll need to install clutter-gtk and mash, and be building gnome-color-manager from git master.
Just want to say thank you very much. I benefit from your previous efforts on a daily basis, and color management is also a very welcome addition to the Gnome desktop. BTW, I like the edge treatment of the tabs left and right of the active tab. Is this new for Gnome 3?
yes, that’s the Adwaita theme engine, the default GNOME 3 theme
Stop reading and implementing my thoughts!!! :D
Do you know if your colour manager is planned to be included in Ubuntu 11.04?
No idea, sorry.
nice toy, but I doubt it is really that useful. The thing about the CIE plots is that they are brightness-normalized, so you really not lose anything important IMO.
And comparing 2D objects is always easier than 3D objects. ;)
Something I would really appreciate is drawing the gamut triangle in the LAB CIE plot. I dont know wheter gcm already does this, as it is not default in ubuntu yet, so maybe you could also promote it there..
