I'll try to explain the desired situation in the end differently: Files coming into GIMP and going out of GIMP might have assigned ICC profiles, this is for import and export. There is no such things as a working space in GEGL buffers flowing between operations in the graph have defined color spaces and each node/operation have their own logic for preferred working space and the raster data is converted before processing. ICC conversion should only happen on import, to a well defined babl supported color space, and on export to whatever preferred color space the user has. The babl color spaces used by GEGL have unbounded gamuts, and the conversions in use are precise conversions rather than conversions implemented using interpolated 3d lookup tables. The consequence of this is that all blending, resampling (scale/rotate), blurring etc. should happen with linear gamma. There should be ways to change the colors in a buffer to correct for a wrong profile. As well as deciding that you want to export images from the composition with a different profile from the input. /Øyvind K.
Sorry if this is an stupid question :-pWhat about display filters/soft proofing/whatever you call display correction?
When/where it happens?There is an interesting section about that here: http://cinematiccolor.com/ (page 29 of the document) I'm not sure if this is too focused on motion-picture work, but the whole document looks very interesting anyway.
Is any of this appliable to GIMP? Gez. _______________________________________________ gimp-developer-list mailing list gimp-developer-list@xxxxxxxxx https://mail.gnome.org/mailman/listinfo/gimp-developer-list
