[Bug 205602] New: picture can't be dispaly top-buttom, it is always rotated to the left or right

https://bugs.kde.org/show_bug.cgi?id=205602

           Summary: picture can't be dispaly top-buttom, it is always
                    rotated to the left or right
           Product: digikam
           Version: 0.9.4
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           0.9.4 (using 3.5.10, Gentoo)
Compiler:          Target: i686-pc-linux-gnu

I'll attach a foto which is desplayed correctly eg with KView, but digikam
shows it w/ 90° rotated to the right. If I rotate this specific picture it is
rotated always in steps of 180 ° :-(

0.9.4 is an old version please try 0.9.6 or 1.0.0beta3. I think I have
encoutered this bug in the past and it as been solved already.

Cheers,

Julien

Thx - I updated to these Gentoo packages :

=media-gfx/exiv2-0.18.2
=media-libs/libkexiv2-0.1.9
=media-libs/libkdcraw-0.1.9
=media-gfx/digikam-0.9.6

w/o success. FWIW last days I upgraded to

=x11-drivers/xf86-video-intel-2.8.1
=x11-base/xorg-server-1.6.3
=media-libs/mesa-7.5-r3

What I realized now, is that rotating seems to work for other pictures, however
the thumbnail doesn't reflect is. But clicking at a picture shows the rotated
result.

Don't forget that tumbnails still in cache in your hard drive. To update it,
with current album, press F5.

To update all thumbnails in cache, go to Tools menu, there is a option to run
in batch... It will take a while of course.

Already did it - it seems that all thumbnails never reflect the rotated images
instead they always show the original orientation.

What I'm wondering about too is that the attached image (the only one between
some hundreds of my holiday in Lisboa) can only be rotated to the right (and
only w/ 180° steps) - probably I rotated it some monthe earlier already and
that's why it have some strange exif info ?

The test image is rotated correctly (portrait) but the Exif tag is set so that
it is displayed rotated by 90°.
The special case here is, if you rotate by 90° in the opposite direction, on
operation on the image is required, just resetting the Exif flag is needed. And
this is currently broken.

SVN commit 1022799 by mwiesweg:

Resetting the Exif rotation flag to NORMAL was broken for two reasons:
- if the rotation was a no-op and only resetting the flag was required,
  the method just returned, skipping the exif adjustment
- libkexiv2 would reject any file without suffix as non-supported RAW image.
  That is fixed now in libkexiv2 and by setting a suffix on the temp file

BUG: 205602


 M  +2 -0      imagerotate.cpp

Any chance to have such a patch for the Gentoo package
media-plugins/kipi-plugins-0.1.7 ? I tried to apply both patches but seems to
be very different code sets between trunk and that (old) version ?
