Color correction

Wolfgang Mader
Hi list,

since 4.10, I guess, KDE comes with integrated color correction. Hence, it is
possible to set the color profile of the monitor and other output devices. It
is not clear to me how a desktop wide color management solution interferes
with the color correction implemented in digikam.

Best,
Wolfgang

As far as I understand, there is no color _correction_ applied by KDE.
What you most likely talk about is color profile management, that is
handled by colord in background. Colord does not apply color
correction, it advertise the current color profile of any device
(which may be a monitor, a printer, etc...). The only difference I've
seen when changing the profile for my monitor is the gamma correction
applied. Color correction should be done by the softwares, like
digiKam, or Firefox (no activated by default for images without a
color profile).

Therefore, there should not be any interference between this color
profile management, and the color correction of digiKam, which by the
way may use a different profile than the one advertised by colord.

Best,

What about multi-screens: each screen should have its own profile; and - if I remember well - there is only one in Digikam settings.

Yes, I know... but that's why I was wondering about the use of the Digikam settings. In which cases do you want it to be different from the system profile(s)?

Yes, multiscreen settings is not yet supported in digiKam. There is
already an entry in bugzilla.

And what about those use system color management installed profile, with dispcal at launch or, for Gnome or Ubuntu Unity, with the color system setting.

Does it needed to set the screen profile in Digikam too ?

I am on Arch Linux and had to install the package kolor-manager separately.
Then you get a new icon on the top level of system settings called "Color
Management" and a new box to tick in the "Desktop Effects" -> Advanced ->
Box(Enable Color Correction (Experimental)).

They use the oyranos framework

Sound like an extra package from your distro not a standard one
distributed by KDE. Here (Mageia3), it do not exist...

officially.

If you are using oyranos framework, then my intial answer is wrong,
since this is different from colord. Oyranos has been available for
quite a while now (contrary to colord which is recent), and I doubt it
will be included in KDE SC. I have no idea also as to the interference
with digiKam color correction.

Colord for KDE is available on ArchLinux with the AUR package colord-kde.

digiKam use Lcms which will handle differently Color profiles than Oyranos.

So, i suspect a big bazaar here...

If there is even a remote interest in adapting this kwin/oyranos based
solution, I would volunteer to research if and when this can be expected to be
included in kde by default. A tleast color correction for multiple different
monitors is working there already.

I want to stress, that this would cut out digikam users which are not using
kwin as their window manager, and this is s.th. we for sure do not want.
Hence, a solution to this end would be needed.

Wolfgang

I just take a look if a Linux Application already support CM with multi-screens.

- Scribus : no
- Gimp : no
- Krita : no

anything else ?
