The "decolorize" algorithm on this page is not just a simple set of weights it is? That algorithm appears to choose luminance values based on perceptual differences in color so that more information is preserved when converting to luminance only (i.e., it tries to make different colors appear with different brightness). I don't think you could do that with a linear mapping. _______________________________________________ Bf-committers mailing list [email protected] http://lists.blender.org/mailman/listinfo/bf-committers
