Bug ID: 413432
Summary: Folder View generates unsharp landscape thumbnails
(whereas portrait/square thumbnails look fine).
Product: plasmashell
Version: master
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Folder
Assignee: h...@kde.org
Reporter: g-...@web.de
CC: plasma-b...@kde.org
Target Milestone: 1.0
SUMMARY
Folder View (/Desktop) generates poor image previews -- but only for landscape
images.
I.e., for the case that the with of the image is bigger than its height, the
corresponding thumbnail gets exremely "unsharp". Square or landscape images
look satisfactorily, though.
Please see attached screenshot (also showing a comparison with Dolphin).
STEPS TO REPRODUCE
1. Put an image having landscape size on your Desktop (e.g. a common photo,
ratio 4:3)
2. Put another image with portrait properties on your Desktop or make a copy of
the first one and cut it to portrait (e.g. ratio 2:3)
OBSERVED RESULT
First image looks unsharp. Second image looks fine.
EXPECTED RESULT
Both images look sharp.
