[bugzilla_noreply]

https://bugs.kde.org/show_bug.cgi?id=368444

            Bug ID: 368444
           Summary: Not supporting XCF anymore
           Product: digikam
           Version: 5.1.0
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Preview
          Assignee: [hidden email]
          Reporter: [hidden email]

Since migration to v5 (5.1 to be precise), Gimp XCF files can no longer be
viewed.

Thumbnails are not generated for new XCF files. If files are clicked, the
preview window says "Failed to load image"

For XCF that were in the database before migrating to V5, thumbnails are still
visible but the files can't be viewed either.

Here's what the logs say:

digikam.general: Cannot create thumbnail for  "/home/timetre/Pictures/02 A
Tagger/2016-09-02-Sous_le_phare/Tassy_20160902_1666.xcf"
digikam.general: Thumbnail is null for  "/home/timetre/Pictures/02 A
Tagger/2016-09-02-Sous_le_phare/Tassy_20160902_1666.xcf"
digikam.metaengine: Cannot load metadata from file   (Error # 11 :
/home/timetre/Pictures/02 A
Tagger/2016-09-02-Sous_le_phare/Tassy_20160902_1666.xcf: The file contains data
of an unknown image type
digikam.dimg.qimage: Can not load " "/home/timetre/Pictures/02 A

digiKam delegate XCF support to KDE5 QImage loader plugins. Install these extra
run-time to solve this problem.

digiKam do not have XCF decoder.

Thanks Gilles

I have the kdegraphics-thumbnailer package installed so that's not it.
Any idea what could be the name of the library providing this support ? There's
a ton of kde packages, kind of hard finding which one gives what's needed ...

kdegraphics-thumbnailers repository has only RAW and PS  support :

https://quickgit.kde.org/?p=kdegraphics-thumbnailers.git&a=tree

kimageformats repository has XCF support :

Yep, you nailed it Gilles !

kf5-kimageformats was the missing package
I only had an old kde4 compatibility lib ...

All good now ! Thanks again !
