           Summary: Kipi-plugins writes invalid EXIF data to image
           Product: kipiplugins
           Version: 0.3.0
          Platform: Mandriva RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: MetadataEdit
        AssignedTo: kde-imaging at kde.org
        ReportedBy: dan at coneharvesters.com


Version:           0.3.0 (using KDE 4.2.4)
OS:                Linux
Installed from:    Mandriva RPMs

After scanning an image with digiKam 0.10.0 using the Import->Scan Images
option, the resulting JPEG file saved had an EXIF data block that was out of
spec: several mandatory EXIF tags were missing. Running the 'exif' program
(ver. 0.6.19) in debug mode (-d) gave this log which shows which tags were
missing:

exif-content: Tag 'XResolution' is mandatory in IFD '0' and has therefore been
added.
exif-content: Tag 'YResolution' is mandatory in IFD '0' and has therefore been
added.
exif-content: Tag 'ResolutionUnit' is mandatory in IFD '0' and has therefore
been added.
exif-content: Tag 'XResolution' is mandatory in IFD '1' and has therefore been
added.
exif-content: Tag 'YResolution' is mandatory in IFD '1' and has therefore been
added.
exif-content: Tag 'ResolutionUnit' is mandatory in IFD '1' and has therefore
been added.
exif-content: Tag 'ExifVersion' is mandatory in IFD 'EXIF' and has therefore
been added.
exif-content: Tag 'FlashPixVersion' is mandatory in IFD 'EXIF' and has
therefore been added.

These tags should be written to every EXIF data block to ensure that the
resulting file conforms to the EXIF specification.

I took a quick peek at the Kipi-plugins source ver. 1.0.0 and saw no sign that
the problem has been fixed.
