Color Managed View - How?

Hi all,

I was reading through the Digikam docs relating to ICC and came across
this surprising sentence:

"The Use color managed view is an alternative to using Xcalib or Argyll.
Only your image will be color managed, not your entire screen!"

How does Digikam do this?  I would think it would need to know how the
monitor behaves in order to render the colors properly...

You are correct, in order to color-manage, digiKam needs to have a monitor
profile.

Yes, and monitor profiles are created by programs like Xcalib and Argyll, aren't they?  I'm confused as to how profiling applications can be taken out of the loop....

Xcalib and Argyll are programs that apply a color profile to X, so all
programs are automatically color-managed as far as the monitor is concerned
(that means that the monitor is somewhat more neutral in its color rendering,
missing color lobes can't be displayed of course, and notebooks are terribly
bad when it come to photographs, no whatever sophisticated color management
can correct that).

Xcalib and Argyll don't manage other devices than screens. So they are partial
color managers.
