Description Michal Lindner 2008-10-16 19:07:35 UTC
Please describe the problem:
No profile (I tested RGB and Monitor profiles) is applied to filter preview.

Steps to reproduce:
1. upload ICC profile that significantly affect colours
2. enable color managed display and select color profile in monitor
3. try some filter with preview (example: Filters/Enhance/Unsharp Mask)
4. couurs in preview will be different to image window

Actual results:
false color

Expected results:
use selected color profiles in preview mode

Does this happen every time?

Other information:
GIMP 2.6.0

Please file bugs in the correct Product. Moving to gimp.
Comment 2 Sven Neumann 2008-10-17 06:34:13 UTC
Yes, that feature is still missing. There are other places that also still are not color managed. See bug #467930 and bug #478528. Patches to implement this are welcome.

I can confirm this issue is still in Gimp 2.6.6 :-(
Comment 4 Michael Natterer 2009-05-13 17:09:07 UTC
Not surprising, since nobody has written a single line of code to
support it.
Comment 5 Michael Natterer 2016-05-24 19:40:02 UTC
I just realized this comes almost for free when making color
selectors color managed, setting milestone.
Comment 6 Michael Natterer 2016-05-24 19:46:28 UTC
Some preparation:

    libgimpwidgets: add gimp_preview_area_set_color_config()

    pixels. This is preparation for fixing:

Should we close this one as resolved now, mitch?
Comment 8 Michael Natterer 2016-08-29 22:26:20 UTC
It's fixed only for the plug-ins which use GimpPreviewArea, need to
double check all plug-ins with a preview and maybe file individual
bugs for the ones which don't (if any).
Comment 9 Michael Natterer 2016-10-04 18:38:36 UTC
There aren't that many plug-ins left... I grepped quickly and it seems
we got them all (no guarantee).

Closing as FIXED.
