Hi Gerhard,

It would be possible to do the following:

- load image's raw data, and ICC profile
- During display, convert from source colorspace to display
  colorspace
- During saving, save the originally loaded ICC profile back to
  file, if the format supports it, or convert to sRGB if it
  doesnt.

The problems with that approach are

- Lots of elements in the GIMP are not colorspace aware - for
  example, you would have to modify the paint tools to detect
  whether there was an ICC profile associated with a display they
  were painting to, and color convert the (sRGB) data that they
  are painting. This is not possible currently, and Sven has
  expressed a desire that color management be kept out of the
  core in the past.
- Data which enters the image from other sources (copy & paste
  from another image, for example) may have been in a different
  colorspace, requiring convertion or some other funkiness to
  keep things coherent inside the image

We currently have the ability to do color proofs with external
ICC profiles. THe interface to the loading of the profiles isn't
perfect yet, but it's there.

Cheers,
Dave.
