SVN commit 493814 by cgilles:

Digikam from trunk : and finally RAW file decoding settings are now used by IE and Showfoto...

Actually, the RAW file decoding settings implementation provide these parameters :

- Enable Quality Decoding (bool) : If disable, we using old dcraw command line syntax with '-q' parameter alone. If Enable we using addition quality factor require by last dcraw release.
- Quality Decoding Factor (int 0-4) : The famous factor using to optimize RAW decoding image (0 for slow computer, 3 for speed computer)
             
TO DIGIKAM TEAM :

- I have tested using this implementation using dcraw v7.49, not the last one released by Dave Coffin.
- We can add any other advanced RAW decoding parameter on settings dialog tab :
   * -f : Interpolate RGB as four colors. This blurs the image a little, but it eliminates false 2x2 mesh patterns.
   * -a : Automatic color balance. The default is to use a fixed color balance based on a white card photographed in sunlight.
   * -w : Use the color balance specified by the camera. If this can't be found, dcraw prints a warning and reverts to the default.
   * -n : By default, dcraw clips all colors to prevent pink hues in the highlights. Combine this option with -b 0.25 to leave the image data completely unclipped.
   * -j : For Fuji Super CCD cameras, show the image tilted 45 degrees so that each output pixel corresponds to one raw pixel.
   * -s : For Fuji Super CCD SR cameras, use the secondary sensors, in effect underexposing the image by four stops to reveal detail in the highlights. For all other cameras, -j and -s are silently ignored.

Notes :

- "-a" and "-w" are always actually enable on the current implementation and work fine. I'm not sure if ti's a good idea to disable these parameters.
- I have never tested "-f" parameter. I think this one must be availabe in setup.
- "-n", "-j", and "-s" are indeep settings. i'm not favorable to add these options, excepted if any users want these parameters...

Please let's me hear if all is right for you ! Suggestions and wishes are welcome

In my opinnion, we must add all color balance options and colors clipe/unclip
feature.

You want say that i need to add 3 new QCheckBox in setup dialog to :

1 - Use automatic Color Balance (-a)
2 - Use  Color Balance from Camera (-w)
3 - Interpolate RGB as four colors (-f)

"clips all colors to prevent pink hues in the highlights" option (-n) is more
complicated to implemente because it's require to set brightness (-b) to
0.25. Have you already used this option ? Have you any feedback about ?

This RAW file decoding option is now available in svn trunk...
