Description Fonkle 2020-09-18 14:23:30 UTC 
SUMMARY


STEPS TO REPRODUCE
1. Open Dolphin
2. Activate 'Details View Mode'
3. Navigate to a folder containing a RGBE / Radiance HDR file (*.hdr)

OBSERVED RESULT

Thumbnails are generated for most image files with the exception of RGBE / Radiance HDR (*.hdr) files.

EXPECTED RESULT
Thumbnails are generated for all known image files.

SOFTWARE/OS VERSIONS
Windows: 
macOS: 
Linux/KDE Plasma: KDE neon 5.19
(available in About System)
KDE Plasma Version: 5.19.5 
KDE Frameworks Version: 5.74.0
Qt Version: 5.15.0

ADDITIONAL INFORMATION

The MIME type for HDR files appears to be 'application/octet-stream' according to file --mime-type. Isn't that supposed to return 'image/x-hdr' for RGBE / Radiance HDR files?
Comment 1 Fonkle 2020-09-18 14:54:14 UTC 
Note: If I manually open the .hdr file using GIMP, the thumbnail is generated and, from then on, correctly displayed in Dolphin.
Comment 2 Christoph Feck 2020-09-18 17:18:20 UTC 
Did you install kimageformats?
Comment 3 Christoph Feck 2020-09-18 17:55:45 UTC 
Oh well, that's odd. These thumbnails show up in Icons view mode, but vanish in Details and Compact view modes.
Comment 4 Fonkle 2020-09-18 18:12:05 UTC 
No, sorry if I explained it wrong. Thumbnails are not being generated in either (Icons / Compact / Details) mode.

If I open the file in Gimp though, the thumbnail seems to be generated. From then on, it is visible in either view mode.
Comment 5 Fonkle 2020-09-18 18:40:04 UTC 
'kimageformats' does not exist in the KDE Neon (5.19) repo. 'kimageformat-plugins' exists and is installed.
Comment 6 Fonkle 2022-05-25 07:58:21 UTC 
This has been fixed a while ago. Should I set its status to 'RESOLVED/FIXED'?
