           Summary: No support to resync GPS data from digikams database
                    into into jpg files
           Product: digikam
           Version: 1.1.0
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: krienke at uni-koblenz.de


Version:           1.1.0 (using KDE 4.3.5)
OS:                Linux
Installed from:    openSUSE RPMs

I created jpg files from my RAW photos using an external program (not digikam).
Next using digikam I correlated a GPS track with the jpg files using the
correlate KIPI-plugin in digikam. After all I had to manually set GPS position
for 10% of the 600 photos I wanted to process. So far everything works fine. 

Then I realized that the jpgs had a compression factor that was to high, so I
recreated all the jgs (with the external program) with better quality and
copied the new files over the old ones. The effect was of course that all the
GPS information stored inside the old jpgs metadata was lost now. However
digikam still knew GPS information of each photo from its database and was able
to show the location of each photo on the map. 

The problem now was how to write this GPS info from digikams database back into
the freshly created jpg files. I tried menu entry "Photo->Write metadata to
photo" but this did not add the GPS information to EXIF allthoug I think it
should since GPS information is also metadata. 

I did not find any other way to automatically batch write back GPS info stored
inside digikams database to the about 600 jpg files.

Thanks
Rainer
