[Bug 255553] New: Batch Color Space Converter Doesn't Work On 16bit TIF Files

Bugzilla from gore@projectpontiac.com
https://bugs.kde.org/show_bug.cgi?id=255553

           Summary: Batch Color Space Converter Doesn't Work On 16bit TIF
                    Files
           Product: digikam
           Version: 1.5.0
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Color Management
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Created an attachment (id=52957)
 --> (http://bugs.kde.org/attachment.cgi?id=52957)
This is how it should look

Version:           1.5.0 (using KDE 4.4.4)
OS:                Linux

When I use the Batch Color Space Conversion tool on TIF files I generated from
DNG files, the resulting pictures have their colors all over the place. I use
16bit ProPhoto RGB as my working color space, but I want to convert to 8bit
sRGB before posting to the web.

Reproducible: Always

Steps to Reproduce:
- Use UFraw to generate a TIF file in 16bit ProPhoto color space (from the
camera's original DNG)
- add this TIF file to the batch queue manager
- add the color space conversion tool
- select sRGB as the conversion color space
- run batch

Actual Results:  
The resulting picture has incorrect colors. Looks like the new colour profile
was assigned to the picture, instead of any conversion being made.

Expected Results:  
The resulting picture should appear at least somewhat similar to the original.

I tried to perform this on TIF files generated by Digikam, but Digikam fails
spectacularly to create 16bit ProPhoto TIFs from DNG files. (a whole different
bug)

Can you please try manually with the image editor?

Open the file in the image editor, use Color -> Color space conversion -> sRGB,
Color ->depth -> 8 bit, save. Is the result correct?

Yes, when I do it manually, the result is correct. It's only when I use the
Batch Color Space Conversion tool that it gives me bad results.

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