            Bug ID: 400492
           Summary: Rotation does not work
           Product: digikam
           Version: 6.0.0
          Platform: Appimage
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: Metadata-Orientation

The file names are self-explanatory

SUMMARY

Rotation functionality does not seem to work properly.

Use the attached images for testing.

In Settings // Configure digiKam // Metadata // Rotation set "write normal flag
orientation after rotate". Other settings as per attached screenshot.

STEPS TO REPRODUCE
Try to manually rotate left or right, autorotate, set orientation flag.

OBSERVED RESULT
The image either does not rotate at all or rotate somewhat unexpectedly.

The orientation flag as per Item // Adjust Exif Orientation Tag remains as
"rotated right", although exiv2 confirms that after rotation, the flags are
"top, left".

Rebuilding thumbnail (Tools // Maintenance) does not change this behaviour.

On some images, the thumbnail orientation flag may become inconsistent with
other orientation flags.

EXPECTED RESULT
The image visually rotates as per instruction, the thumbnail is rebuilt and
orientation flag is set to normal in all metadata types (Exif, Thumbnail, TIFF,
etc.).

SOFTWARE VERSIONS
digikam-6.0.0-beta2-20181030T031645-x86-64.appimage

OTHER INFORMATION
The inconsistency of orientation flag in metadata seems to have different
impact on different actions (autorotate, rotate manually in Thumbnails view, in
Preview View).
