Description Michal Thoma 2010-05-17 20:22:01 UTC

Version:           1.2.0 (using KDE 4.4.2)
OS:                Linux
Installed from:    Ubuntu Packages

ICC Convert function in BQM is faulty, because it changes only color values, though no ICC Color profile tag. 

So if you convert AdobeRGB image to sRGB, color managed display will be wrong, because this sRGB color space image will be identified a treated still as AdobeRGB (according to color profile tag).

How to reproduce: 

1 - Take image in any known and set color space (i.e. sRGB).
2 - Put it to BQM and set Convert ICC to some other color space (i.e. ProPhotoRGB) and process it.
3 - Check visual differences between converted and original image. Check color profiles of both images with Color tab at right sidebar.

SVN commit 1182660 by cgilles:

With ICC convert tools, assign right ICC profile to target image and remove Exif color space tags.
