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
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Created attachment 115991

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).
