Description hoea 2004-09-09 00:02:12 UTC

Version:            (using KDE KDE 3.2.1)
Installed from:    SuSE RPMs
OS:                Linux

jpeg pictures taken with a digital camera (i have got a 
canon powershot) have got orietation information included.

portrait pictures are displayed ok within konqueror, but if selected
as wallpaper they are shown sideways.

additional info: konqueror shows meta-info/jpeg-exif: orientation=6 or
orientaton=8

Comment 2 Jochen Deibele 2004-09-20 23:23:38 UTC

Still in Kde 3.3 (also SuSE RPMs)

Comment 3 James 2005-03-13 00:05:50 UTC

Still in 3.4.0-RC1

It's actually quite confusing since Konqueror when running as a filemanager understands the orientation, as does Kuickshow and the fancy new Photobook view.
