Description Alexios Beveratos 2009-04-07 21:56:03 UTC
Version:            (using KDE 4.1.3)
OS:                Linux
Installed from:    Mandriva RPMs

The latest version of digikam does not save the color profile. When a photo is loaded in the editor which does not match the color profile, it asks if one wants to change or apply. 

Then the photo is saved using Save As (as in the KDE3 version) but when the photo is opened again, the profile does not seem to have been embedded. The question is asked again

Sorry, I forgot

I only tested with JPEG

Please test with others file format which support ICC as TIFF and PNG to see if problem is general or only with JPG

the ICC profile is properly saved in PNG and TIFF format

I'm getting this as well -- images I upload to Facebook have a blue tinge.

When I import the JPEG into the Gimp, it says the JPEG contains a colour profile named "sRGB", and asks whether I want to convert it or keep it.  Both options result in the same blue-tinged image.

Krita doesn't prompt me like the Gimp does, but it takes a little while to open the image, which suggests to me that it's silently "converting" the profile.  The same blue tinge results.

The workaround I've been using is to convert my JPEG to BMP using ShowFoto, then convert the BMP back to JPEG before uploading.  I'm guessing that the removal of the colour profile at the BMP stage is the key.  Using PNG as an intermediate format instead of BMP does not fix the problem, presumably because the colour profile is copied into the PNG?

This bug is a combination of two distinct problems (failure to read ICC profiles from JPEG files; usage of an sRGB profile that was not standard sRGB).
Should be fixed from 1.0-beta4 on.
