           Summary: Problem with opening 16bit TIFF
           Product: digikam
           Version: 0.9.0-svn
          Platform: Slackware Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: dudasg freemail hu


Version:           0.9.0-svn (using KDE KDE 3.5.1)
Installed from:    Slackware Packages
Compiler:          gcc 3.3.6 
OS:                Linux

Opening a 16bit TIFF file (that is generated by an external RAW converter software) is not possible both in digikam or showfoto. More precisely: After clicking on the TIFF file it writes "TIFF file identified" to the console, but the opened editor/viewer shows pretty weird output (black and white overlapped lines, that reminds to the original image).

The file can be downloaded from:
http://amigos.amiga.hu/dudeeg/digikam_tiff/IMG_4224-01.tif


The output from "identify" :

$ identify -verbose IMG_4224-01.tif
