           Summary: thumbnail generation fails with raw images
           Product: digikam
           Version: unspecified
          Platform: SuSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: auer m-otion at


Version:            (using KDE KDE 3.5.1)

Compiler:          gcc (GCC) 4.1.0 
OS:                Linux

Raw images from my Kodak DSC Pro camera produce only distorted thumnails. After I removed the first part of the loadDCRAW function in digikamthumbnails.cpp ( where it says "first try with Dave Coffin's "parse" utility" ) thumbnail worked correctly, but performance isn't very good, it takes about 5 seconds per picture, which wouldn't be much of an problem, if digikam wouldn't generate thumbnails only for visible pictures... this way it need a lot of time and constant interaction, until a folder with 600 raw images has all its thumbnails. Theoretically thumbnails from the Kodak files could be created very quickly, since they are basicly tiff images an have embedded thumbnails.
Also exif information isn't displayed, but I guess this is more an libexiv2 issue, although I think exif information for the kodak raw images worked in earlier versions of digikam, but I am not sure.

I uploaded a test image to this location:
