Joseph Simon announced today the first release of his KDE Color Management front end to the Oyranos library. Read the full announcement for KolorManager on Joseph’s blog.
The new minor release of the icc-profiles-openicc package contains a newly created ProPhoto-RGB.icc profile. It was peer reviewed by the OpenICC group. The profile is intended for use in cameraRAW applications like digikam. ProPhoto-RGB covers the very wide colour gamut of modern photo sensors. One difference to existing profile versions of the colour space is it’s liberal licensing.
- new Spyder 4 display colorimeter supported (Note that the user must supply calibration data)
- new experimental support for ColorHug display colorimeter (read instruction how to enable)
- add -y option for extended display selection and tweak integration times
The later feature hints, that some newer instruments speed up with measurement times and need now more careful adjustments in order to not interfere with display frequencies.
About: ArgyllCMS is the primary tool set in the open source world to access colour measurement devices and to create ICC profiles. Together with it’s colour conversion and analysis capabilities it is located in the tool box of many colour management professionals. Several freely distributed graphical front ends exist for ease of handling.
As mentioned in a post before, the Libre Graphics Meeting will be held in Vienna from 2th until 5th of May this 2012. I have now submitted my talks and will hopefully know in some days if they are accepted.
Colour Management a la Greek: will give a overview about some technical concepts for platform independent color management systems.
Evolving Concepts for Colour Management: will summarise the ongoing ideas and discussions on the freedesktop working group OpenICC.
Like in the years before, there is a chance to meet with students of the upcoming Google Summer of Code projects.
Sirko submitted Taxi DB – Call A Cab To Bring The Colors: which describes the idea behind the ICC profile database and hopefully we getting some feedback and ideas, on how to make sure, that the quality of the profiles will be high.
Markus Raab has submitted a talk about Elektra, which is used as DB API by Oyranos. I hope that will show new lively developments in Elektra
I am sure the self-styled competitor will also be around and give an talk about his view on color management.
If we can get to useful work on specs on a OpenICC round table for the sake of cross desktop compatibility, then even better.
Gustav likes to attend the Libre Graphics Meeting, but he needs some support to get there. We should help him, so that he can meet Boudewijn Rempt and some others from Krita, who can help him to find his way to the KDE community. But he needs some money for travelling. And there are still some other requests for generosity I mentioned before.

Libre Graphics Meeting (LGM) is coming along nicely and will surely become again a cool event for the FLOSS community. LGM is this year co-located with the Linuxwochen Vienna and their Call for Papers is still open until 1st of April.
A new version of the compiz plugin for ICC colour correction of monitors is released. This release is a feature release.
- new support per region ICC profiles
- new switch to X Color Management specification
- require libXcm-0.5.0 and Oyranos-0.4.0
Changes from 0.8.4:
- fix alpha blending
- speed up load time (cache the transformed pixels in memory)
The project brings you instant desktop colour correction on GPU through the compiz window manager (0.7.x/0.8.x). It supports multi monitors and live connecting. The implicite colour conversion appears on the fly. To opt out of colour correction for specialised graphics applications the X Color Management spec 0.4 is supported. Devices can be configured through the Oyranos Colour Management System.
ICC Examin Version 0.51 is a feature release. The package newly explores into window and OpenGL colour correction and contains bug fixes.
- new on the fly large gamut intermediate ICC profile
- new let a colour server colour correct OpenGL
- new Oyranos colour corrects report window on CPU
- fix regression in file observation
- require Oyranos 0.4.0
ICC Examin is a small utility (unix name: iccexamin) for the purpose of watching the internals of ICC v2 and v4 profiles, measurement data (CGATS), colour samples (named colour profiles), gamut visualisations (vrml) and video card gamma tables (Xorg/XFree86/osX).
ChangeLog Version 0.51
Thanks to all contributors and bug reporters.

The new version of the colour management system Oyranos is released. Version 0.4.0 is a feature and bug fix release.
- new list Taxi DB profiles for a local monitor
- new download and install ICC profiles from Taxi DB
- fix HDMI2 XRandR EDID
- new widget classes to image_display for per window CM
- new add oyranos-monitor-daemon script
- switch to libXcm 0.5.0 for X Color Management support
Oyranos is a colour management system allowing to share various settings across applications and services. The provided interfaces are the C library, native graphical front ends and partitial access through command line tools. The library is licensed under newBSD.
Known Applications using Oyranos:
ICC Examin, the KDE Kolor Manager and Synnefo configuration dialogs, the CompIcc colour server and more.
Thanks to all contributors and bug reporters.
This is a major new release of libXcm, the X11 Color Management library. The name space of the core protocol changed with the new spec.
- switch from net-color to X Color Management specification 0.4
- support per region ICC profile
- add API to parse capabilities from _ICC_COLOR_DESKTOP atom
- use autotools
- add XcmVersion.h file
- build under osX and Win32 without X11 and Linux specific parts
The library communicates X colour regions between server and clients, which is described in the included X Color Management spec. EDID data can be fetched through i2c communication. EDID data can be parsed for identification and access to colorimetric
calibration data. libXcm helps in observing known X11 colour management events.
Known applications using libXcm:
The library is used by CompIcc a compiz plugin for full screen colour correction in hardware. libXcm allows the plugin to support multi monitor and multiple regions per window. The Oyranos Colour Management System uses the EDID parser. qcmsevents applet observes and displays colour management events in a nice GUI. Xcm contains three command line tools for EDID fetching, EDID parsing and event observing.
The Libre Graphics Meeting is the annual event for open source creative graphics software. It greatly helps in improving the open source software stack through lots of talks, discussions, round tables, work shops and wonderful face to face meetings. There is always a great mixture of developers, artists, writers, translaters and interested people present, who come together in a very friendly and inclusive atmosphere. We had in the past always a OpenICC round table, when I was at LGM, and discussed various topics and planed around colour management. That should happen this year again with many ideas coming up.
To get people from all over the world to Europe, we need your help:
Sirko has created another pledgie:
Some days ago on FOSDEM I gave a presentation about Colour Management in Compositors. At that point is was not very clear how to introduce colour management especially into the upcoming Wayland display server core and thus make it wide spread. The answer from Wayland developers is the same as from Xorg ones. They want a small core and colour management does not fit inside this.
As a result of a discussion between several colour management interested people from wayland, toolkits and me on the wayland IRC channel, we found a smallest common denominator. That will be a per window colour correction mechanism. The advantage is, it will be very easy to implement inside compositors and they can even start today about ICC support. The biggest disadvantage for applications is, they need to colour correct the whole window. That is as well the reason, why I did not like the idea in the past. Anyway, hopefully toolkits will jump in at one point and make that easy. Meanwhile we need to focus on example code, which demonstrates how per window colour correction can work.
The spec can be found as usual in the libXcm git repository. The main new part is the _ICC_COLOR_OUTPUTS atom and XcolorOutput structure.
