Dear experts,

I am trying to improve the G’MIC plug-in by adding color
of the preview area. For this, I need to retrieve the GIMP
profile from inside the plug-in code.

What preview area do you use? In git master you simply call


G’MIC uses the following code to initialise the preview area:

    const int preview_drawable_id =
    gui_preview =

Can it be used with gimp_color_area_set_color_config()? I could not
find any documentation of the latter function...

In GIMP git master, you would say

gimp_preview_area_set_color_config (gimp_preview_get_area (preview),
                                    gimp_get_color_configuration ());

I wouldn't bother to do anything with plug-in color management.

I don’t understand what you mean… in the G’MIC plug-in, the preview
area is used to judge the visual output of a given filter, and to
tweak parameters accordingly. 
However, if the monitor profile is not taken into account by the
plug-in, in many cases the g’mic preview will not match what the user
sees on screen once the plug-in is closed… this makes any serious
usage of the g’mic plug-in at least questionable.

So personally I bother a lot improving the g’mic plug-in in this
direction, and I’m ready to spend some spare time on that. But I need
to know how to retrieve the monitor profile.

My question was if this is a plug-in against GIMP 2.8 (soon obsolete)
or against GIMP git master.

I wouldn't bother do add color management to a GIMP 2.8 plug-in
and I have never tried.
