Bug ID: 433660
Summary: OpenEXR does not create thumbnails for files larger
than 1 MByte
Product: kio-extras
Version: 20.08
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Thumbnails and previews
Assignee: plasma-b...@kde.org
Reporter: fon...@mail.com
Target Milestone: ---
SUMMARY
Thumbnails for OpenEXR files larger than 1 MByte are not generated.
STEPS TO REPRODUCE
1. Start Dolphin
2. Navigate to any folder containing an OpenEXR (.exr) file with a filesize
larger than 1 MByte
3. Set the view mode to 'Icons'
OBSERVED RESULT
No thumbnails are generated for files larger than 1 MByte.
EXPECTED RESULT
Thumbnails should be generated for all filers smaller than the 'Skip Previews'
settings in Dolphin (General->Previews)
SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux/KDE Plasma: Kubuntu 20.10
(available in About System)
KDE Plasma Version: 5.19.5
KDE Frameworks Version: 5.74.0
Qt Version: 5.14.2
ADDITIONAL INFORMATION
I have submitted a merge request to fix this bug:
https://invent.kde.org/network/kio-extras/-/merge_requests/77
The OpenEXR thumbnailer used KSharedConfig::openConfig() to get the Maximum
file size, however that looks for the 'MaximumSize' value of the
'PreviewSettings' group in filename 'thumbnail.sorc'. Since the 'MaximumSize'
value is actually stored in the 'kdeglobals' file, it always uses the default
value, which is 1024*1024 bytes, skipping all files larger than that.
