Description Achim Bohnet 2004-08-26 11:31:25 UTC 
Version:           0.7.0-cvs (using KDE 3.2.3,  (3.1))
Compiler:          gcc version 3.3.4 (Debian 1:3.3.4-7)
OS:                Linux (i686) release 2.6.7-ach-1-686

I've used 'set exif orientation tag' -> 'rotate 90 degrees'
(orientation is now left - top)
so picture looks correctly in albums thumbnail view.  A
doubleclick on the picture displays the picture upside down
in the imageeditor.

Looks like image editor rotate in the ccw instead of cw.
What a surprise for (lucky) people with a camara that has
a orientation sensor.

Comment 1 Ralf Holzer 2004-08-26 17:13:55 UTC 
Can you try to set the orientation tag to "rotated 90 deg., vert. flipped"? I have images that were stored with this orientation, which looks like its simply 90 degrees rotated, but it is also flipped. There might be a bug in the thumbnail rotation, so that it shows up correctly there. I'll look into it.
Comment 2 Ralf Holzer 2004-08-26 17:45:28 UTC 
There were two different bugs that messed things up. I skipped the "vertical flip" option when I moved the EXIF stuff to the image menu. And the transformation order when doing a rotate and flip was wrong in the image viewer. It's both fixed in cvs.
Comment 3 Achim Bohnet 2004-08-26 23:07:19 UTC 
Thx!
Comment 4 Jens 2005-01-07 17:07:00 UTC 
Hello,

I think we need to reopen this bug because this behaviour is still in 0.7.1 (compiled from source, by SuSE, for KDE 3.3.2). I make pictures with a Canon Digital IXUS 330 and:

- if I don't enable the "rotate according to EXIF" checkbox in the settings,
  - the thumbnails are(!) rotated correctly
  - showfoto does not rotate at all
  - fullscreen slideshow does not rotate at all

- if I enable the setting,
  - thumbnails are NOT rotated
  - showfoto rotates correctly
  - but the fullscreen slideshow still does not rotate.

This makes Digikam unuseable as a slideshow application, which really annoys the heck out of me because I want these ultra-cool OpenGL effects, dammit! ;)

Also, fullscreen is still not Xinerama aware, but that's another bug I'll have to re-open. Here's the EXIF info out of one of my portrait mode photos:

Comment 5 Renchi Raju 2005-01-07 19:44:06 UTC 
can you email me (renchi@pooh.tam.uiuc.edu) these pictures. showfoto and slideshow are not exif aware yet. can you file a bugreport for the slideshow one (product: kipiplugins, component: slideshow)
Comment 6 Jens 2005-01-14 10:23:26 UTC 
[Resolution: Bug apparently only occurs if "use thumbnail embedded in 
images" in Konqueror is selected, because Konqueror and Digikam differ in 
how they save/respect the rotation info in thumbnails.]

I never touched my photos since they came out of the camera, so that's not 
possible. I never edited them. Maybe, though, my camera (and Konqueror, 
and all the other apps I've since tried, like GQview and Gwenview) applies 
the same EXIF rotation info to the thumbnail, and doesn't rotate the 
thumbnail itself; and Digikam doesn't.

Yes, but ... is there a way to fix this? E.g. by teaching digikam to use 
the embedded thumbnails as well? =;)

I am not too fond of having to disable one of Konq's features to be able to 
fix a bug that appears between the two (no matter what app exactly is to 
be blamed for this) ... ;)

This is related to Bug 97048 and Bug 97484.
