I don't see how (2) could work without adding color management throughout the application and most plug-ins. This is certainly a goal for the time with GEGL but nothing that we should target for 2.2. It seems to me that (1) is the best solution for now. I propose however that we keep most of this functionality in a color-management plug-in. Such a plug-in would offer to apply color profiles and to change the color profile attached to an image. Combined with a color display filter to handle the monitor profile this would keep the lcms dependency to a few defined places and would still allow us to add some basic color management. This should allow us to collect some experiences in this new area. Experience that should help us to get color management right in GEGL. > I was talking to Sven on IRC, and he seemed to believe that neither > of these would be done for 2.2, and that only the infrastructure > which would allow these to be done easily post-2.2 (when we hope to > have higher bitdepths internally for image data).

I think that we should focus on adding the API that is needed to implement some basic but useful color management in plug-ins and modules. Whether this means that 2.2 will include these plug-ins and modules or if they will be developed separately (and perhaps even after 2.2 is released) remains to be seen. Sven
