The problem with large projects is that for a long time there is often no real progress, then all of a sudden stuff just starts to work.

For the curious, on the right is the infamous Evolution showing the address book, and on the left is a terminal running the address book backend. The two normally communicate via Bonobo, but these are communicating via DBus...

The first step is to associate an ICC profile to each screen. This can be done using xicc, from xicc-0.1.tar.gz. Simply run this specifiying the path to the relevant ICC profile and it will set the atom on the root window of the default screen (multi-screen support will be implemented next). For example: 

$ xicc ~/tmp/ICM/ibmtplcd.icm

ibmtplcd.icm is the profile for the IBM ThinkPad LCDs.

Then patch Eye Of Gnome with this patch. Now when EoG opens a JPEG image which describes the colour space using the standard EXIF properties White Point and Primary Chromaticities it will create a profile on the fly, and when the image is displayed the profile for the screen is obtained and the image corrected.

There is a lot to do yet:

  • Read embedded ICC profiles from JPEG and PNG files
  • Read the whitepoint/chromatic information from PNG files
  • Cache the profile from the screen
  • Make xicc multi-screen aware

But it does work! I'll write a small specification for the atom I'm using shortly.
