Hi all,
not sure if it is relevant at all (I know next to nothing about color profiles and haven't read this thread in detail), but I remember seeing this paper about color-to-grayscale conversion a while ago, which may or may not be of interest: http://cg.postech.ac.kr/research/robust_c2g/ Just thought I'd throw it in, in case anyone is interested (be if for this feature or just generally).
Cheers, Max

Hi all, I just committed a new display mode: grayscale. It is separate from the other display modes. The grayscale mode is a "Color display mode", see the menu. When activated, it shows all colors in grayscale on-canvas. This does not (yet?) influence exporting, or saving. It only concerns the on-canvas view of the file, like outline display mode.
Right now, there is no preference to change the grayscale calculation. At the moment it uses: grayscale value = 0.33 * red + 0.59 * green + 0.11 * blue. I found this somewhere on internet, but forgot where, and it might be wrong/unusual. I intended to add a preference setting for these values, but have not done so. Let me know if that is desired.
I tried assigning Shift+keypad5 to toggle the color display mode, but it does not work here on my netbook (Ctrl+keypad5 does work). Perhaps this is a Windows bug. If someone can suggest another keybinding, or... thanks!
