Roger,
this would mean that "perceptual" as a different meaning depending on
which tool you use, right? How Argyllcms does this?
Is the same true for Relative colorimetric? Is only a change in
saturation considered with the relative intent or something else?
My understanding of a color is that it is defined by a point in some 3
dimensional colorspace and if you have to move it around and you limit
yourself to only changing saturation your giving up 2 other potential
options. I would have thought the most recent "distance" metrics or
even the simple euclidean distance to be more appropriate then just
shifting the saturation as seems to be the case in the various docs I've
seen. I know I may not have seen the "right" one. That's why I ask.

It's considered their "secret sauce".

Subject: [argyllcms] Rendering intent?
Hi,
I'm curious, every time I read some doc on how relative colorimetric and
perceptual intent works, it seems as if it only a saturation (2D) change is
considered, why not the shortest distance (3D) to the gamut boundary of the
destination space?
Can you direct me to something that would explain how Argyllcms does this.
Thanks,
Yves
