[digikam] [Bug 334160] New: wrong colors when importing CR2 with custom camera profile

            Bug ID: 334160
           Summary: wrong colors when importing CR2 with custom camera
                    profile
    Classification: Unclassified
           Product: digikam
           Version: 4.0.0
          Platform: Compiled Sources
               URL: https://drive.google.com/folderview?id=0B-2EzyUZBAHmb1
                    d5VlJwNEtPSFk&usp=sharing
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: NOR
         Component: Color Management
          Assignee: [hidden email]
          Reporter: [hidden email]

Importing a CR2 file using a custom camera profile creates an image with strong
color tint (red'ish). The same image converted to tiff using draw_emu from
libraw-tools appears correct.

The profile was generated using argyllcms scanin/colprof.

Reproducible: Always

Steps to Reproduce:
1. In digikam raw import dialog, set camera profile to "custom" and use the ICC
profile _MG_2289.icc from the demo URL and workspace color profile to the
actual workspace color profile
2. import the file _MG_2289.CR2 from the demo URL
3. compare result with the same file converted with dcraw_emu using the
following command:
dcraw_emu -w -q 8 -o 2 -M -T -p _MG_2289.icc _MG_2289.CR2
Actual Results:  
The images don't match. The file created in digikam has a strong red'ish color
tint

Expected Results:  
digikam generated image is expected to look identical to the image created on
the commandline

Matthias,

It's reproducible using last digiKam 4.9.0 with last libraw and last lcms2 ?

With digiKam 5.0.0, this problem is not reproducible.
I close this file now. Don't hesitate to re-open if necessary.
