Status of icc profile integration for output devices?

Thu Dec 21 02:22:08 UTC 2023

Hi there,

Let me start with an apology posting this here on the development mailing list rather than somewhere more user related. Unfortunately, I couldn't find a forum/community for Weston/Wayland, so if there is a better place please let me know.

I was trying for a couple of days now to apply an output icc-profile to Weston (13.0.90), but it seems to have no impact. So I am not sure if there is an error in my weston.ini file, if the profiles are not applied in the way I would expect them to or if this functionality is not fully implemented. Regarding the latter I went through the release history and saw in some discussions about color management and HDR that this feature should be implemented about 2 years ago, but maybe I misunderstood. I would be grateful for any clarification.

Here my setup:
The idea was to have a green background in the shell, and apply an icc profile that swaps green and red colors (SwappedRedAndGreen.icc was available in my Ubuntu installation) , so I would expect to see a red background in the compositor when the icc profile is applied. However, the background does not change.

My weston.ini:

[core]
color-management=true
[shell]
background-color=0xff00ff00
[output]
name=WL1
mode=300x400
icc-profile=/usr/share/color/icc/colord/SwappedRedAndGreen.icc

The corresponding startup log:
