The WebP file works without problems here. Do you use the digiKam Ubuntu packages or our AppImage? Please set the Qt Debug variable and give us the log from the terminal when trying to open the image. https://www.digikam.org/contribute/ Maik I use the snap: https://snapcraft.io/digikam This repeats for every one of my webp files when I open the directory: ``` digikam.metaengine: Check ExifTool availability: false digikam.metaengine: ExifTool is not available to load metadata... digikam.metaengine: Loading metadata with "Exiv2" backend from "/media/..../2577a254-6362-4df1-988e-f7dc44320a90.webp" digikam.general: Trying to get thumbnail from "/media/..../2577a254-6362-4df1-988e-f7dc44320a90.webp" ( "image" ) digikam.general: Trying to get thumbnail with Exiv2 for "/media/..../2577a254-6362-4df1-988e-f7dc44320a90.webp" digikam.general: Trying to get thumbnail with DImg preview for "/media/..../2577a254-6362-4df1-988e-f7dc44320a90.webp" digikam.general: Trying to get thumbnail from Embedded preview with libraw for "/media/..../2577a254-6362-4df1-988e-f7dc44320a90.webp" digikam.rawengine: Failed to load embedded RAW preview digikam.general: Trying to get thumbnail from half preview with libraw for "/media/..../2577a254-6362-4df1-988e-f7dc44320a90.webp" digikam.general: Trying to get thumbnail from Embedded preview with Exiv2 for "/media/..../2577a254-6362-4df1-988e-f7dc44320a90.webp" digikam.dimg: "/media/..../2577a254-6362-4df1-988e-f7dc44320a90.webp" : Unknown image format !!!

It uses a sandbox and has many known issues. The snap package does not appear to contain the KImageFormat plugin. KImageFormat is also used by Gwenview. Also, ExifTool doesn't work either. Report the problem to Ubuntu, they should finally build a native digiKam package. Use our AppImage instead, just make it executable and start it. The upcoming digiKam-8.1.0 as AppImage can be downloaded here: https://files.kde.org/digikam/ Maik First of all, I can confirm that the AppImage doesn't have this issue. > Report the problem to Ubuntu, they should finally build a native digiKam package. They already have, right? https://packages.ubuntu.com/jammy/digikam Just with jammy it's stuck at 7.5.0, which doesn't support webp yet. > Use our AppImage instead, just make it executable and start it. I'm a bit hesitant, because it wouldn't auto-update, as far as I understand. One of my reasons for using Linux instead of Windows is not having to update each and every application manually / separately. > The snap package does not appear to contain the KImageFormat plugin. Could that be changed? I can't find where the snap is built from. Found the snap config here: https://invent.kde.org/packaging/snapcraft-kde-applications/-/blob/Neon/release/digikam/snapcraft.yaml Sadly running it locally requires LXD and thus a bunch of disk space and patience that I don't currently have. Could we solve this issue by adding something like `libkimageformat` (though that particular probably one doesn't exist, I made it up) to one of the packages sections in that config file? (And can we have the CI do the building, so it doesn't require a local build environment?) Hi Scarlett, I moved this report in Neon/Snaps packaging section... Including KF5::KImageFormats dependency will solve this issue at run-time. digiKam has a Qt Image Loader plugin which will automatically support WebP if KImageFormats modules are present. Best Gilles Caulier https://invent.kde.org/graphics/digikam/-/merge_requests/231 Will fix this. Git commit c14d969975d3e17e09510227742a06bc81a66965 by Scarlett Moore.

Created attachment 159740 [details] One of the files that fails to load. SUMMARY According to the release notes, 8.0.0 supports webP. But I get an error and don't see the images. STEPS TO REPRODUCE 1. View a folder that contains webp files (example attached). 2. Open one of those files. OBSERVED RESULT In the overview, only a green dummy thumbnail is shown. In the per-file view, the view remains empty (black) and at the top right it says "Failed to load image". EXPECTED RESULT Renders the image. Like nomacs, Xviewer, GIMP and Dolphin do just fine for the same file(s). SOFTWARE/OS VERSIONS Mint based on Ubuntu 22.04. KDE Plasma Version: 5.24.7 KDE Frameworks Version: 5.98.0 Qt Version: 5.15.3
