the wallpaper renderer (private class in libplasma) doesn't do -any- rotation at all. for this to work, the wallpaper plugin in kdebase would need to link against kevix2 if it is available, or the exif rotation reading would have to be reimplemented in the wallpaper renderer using libexiv2 (if it available).

Screenshot: vertical image in Desktop Settings but horizontal wallpaper image.

Plasma depicts the image vertically in the Desktop Settings window, but does not rotate the image wallpaper.  This behaviour appears to be a bug - can Plasma not leverage the same information to rotate wallpaper as it uses to rotate the preview?  Note that Dolphin also automatically rotates the image.

On a side note, a thanks to the developers for an excellent and generally seamless wallpaper switching process.

I'm planning to work on this functionality quite soon, but I'm not familiar to KDE coding uses and especially dynamic library loading (when present), can anyone tell me where in can find a sample in the KDE source code ?

Hello!

This feature request was filed for KDE Plasma 4, which reached end-of-support status in August 2015. KDE Plasma 5's desktop shell has been almost completely rewritten for better performance and usability, so it is likely that this feature request is already implemented in Plasma 5, or is no longer applicable.

Accordingly, we hope you understand why we must close this feature request. If the requested feature is still desired but not implemented in KDE Plasma 5.12 or later, please feel free to open a new ticket in the "plasmashell" product after reading https://community.kde.org/Get_Involved/Bug_Reporting

If you would like to get involved in KDE's bug triaging effort so that future mass bug closes like this are less likely, please read https://community.kde.org/Get_Involved#Bug_Triaging

Thanks for your understanding!

Nate Graham
