I don't know how far along this is in CVS but the last snap shot I looked at,
2.3.6, still needed significant work to have usable color management
facilities. You will definitely notice that there are significant new
features and what is there is working. But the following (from memory so
may not be complete) still needs to be done as of 2.3.6:
1. There is only limited support for embedded profiles. Only png files
worked. So tiff and jpeg users will have limited functionality.
2. Embedding profiles and doing color space conversions is not supported. So
you must use an external application for this such as lcms or ImageMagick
3. It is currently coded to use the default RGB profile as the source profile
for all images. I don't know if this the case with pgn files since it will
"- load and save embedded ICC profiles from/to PNG images". But this does
allow users of jpeg and tiff images to use what is there. You just have to
manually set the correct source profile for your image in the preferences
dialog. This is a little confusing if you don't know what is going on but
this is apparently for testing during development and this will not be how
this will work when this is released.
4. There are no facilities to handle CM during the printing process.
I am looking forward to the next snap shot. Hopefully it will have a more
complete CM implementation.
