Public bug reported:
When I visit a photo folder in digikam, and then auto-rotate the photos using
imagemagick (convert -auto-orient myphoto.jpg myphoto.jpg), then digikam shows
it rotated twice (just as if the file data had been rotated, and the EXIF tag
was still present). For example, if the photo was initially rotated right, it
will now be shown rotated left, rather than upright.
Jhead shows that such photos no longer have any EXIF orientation flag at all.
No matter of refresh, F5, clear thumbnails seems to convince digikam to
take another look at the EXIF header to clear its cached copy of
rotation flag.
The only thing that helps is to do Image->Adjust Exif Orientation
Flag->Normal on each concerned photo individually.
1) root@hitchhiker:~# lsb_release -rd
Description: Ubuntu 14.04.4 LTS
Release: 14.04
2) root@hitchhiker:~# apt-cache policy digikam
digikam:
Installed: 4:3.5.0-0ubuntu10
Candidate: 4:3.5.0-0ubuntu10
Version table:
*** 4:3.5.0-0ubuntu10 0
500 http://be.archive.ubuntu.com/ubuntu/ trusty/universe amd64 Packages
100 /var/lib/dpkg/status
3) What I expected to happen
Even when an external program modifies the photo, digikam should (eventually)
pick up the changes. It does pick up the changes within the bitmapped data
after all.
Even without autodetection of the change, I'd expect that explicit refresh or
clearing of thumbnails would do its job. Digikam's caching shouldn't be so damn
stubborn.
4) What happened instead
There seems to be no way to cause digikam to re-read the orientation
flag in the Exif header, short of visiting each affected picture
individually and do Image->Adjust Exif Orientation Flag->Normal
P.S. I do know that digikam has its own autorotation function
(Image->Autorotate/Flip using Exif Information), but for some reason
this is *much* slower than using imagemagick...
