Created attachment 94905 [details] Gwenview correctly fits image (using y-size as x-size for rotated images) but won't rotate it, rotate button is missing Gwenview won't correctly auto-rotate images upon exif data. It is evident that it tries to do so (as it fits image to screen using y-size as x-size for rotated images, but won't rotate it. Moreover rotate button is missing both from context menu as well as from tool bar, so on can't even manually rotate image. Very annoying bug, which made me switch to another viewer temporarily. I'm using packaged version of 15.08.1 from kubuntu-ci-ubuntu-stable-vivid ppa in conjucntion with Plasma 5.4.
Rotation button being missing might be https://bugs.kde.org/show_bug.cgi?id=236059, for which I have submitted a patch. Gwenview uses EXIF rotations tags fine for me using a more recent Wwenview than what you're using, and I can rotate them, too.
