            Bug ID: 413926
           Summary: Incompatibility between software, for face regions on
                    auto-rotated portrait position photos
           Product: digikam
           Version: 6.3.0
          Platform: MS Windows
                OS: MS Windows
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: Faces-Engine

Portrait pos photo opened in Photo Station, after adding face tags with
DigiKam.

SUMMARY
Face tag incompatibility between DigiKam and Synology Photo Station was
observed, for upright (portrait) position photos, straight out of camera (auto
rotated into upright position).
I have not observed this on any "landscape" position photos.

STEPS TO REPRODUCE
1. Take a photo in portrait position (perhaps you need a camera that writes
meta data about camera position, for auto rotation).
2. Add two face regions to the image, using DigiKam.
3. Open the image in Synology Photo Station 6 or perhaps any other program that
can show face tags.

OBSERVED RESULT
The regions are not in the same places when opened in Photo Station, as they
were in digikam.

EXPECTED RESULT
Would expect them to be in the same places.

SOFTWARE/OS VERSIONS
Windows: 10
macOS: 
Linux/KDE Plasma: 
(available in About System)
KDE Plasma Version: 
KDE Frameworks Version: 
Qt Version: 

ADDITIONAL INFORMATION
I resized the image, and rotated it to the right, and then back to the left,
added the tags anew (they disappeard with the resize I think). Now the face
tags showed on the same place in Photo Station, so my guess is that the
rotation or resize made something. Perhaps the auto rotation meta data was
changed or removed, and the image. 
I'm not sure which program to blame, DigiKam or Photo Station. And I don't
really know anything about auto rotation, or where that is done, but when I
take upright photos with my camera they are presented upright on my computer,
no need to rotate manually.
