A bit of ROME 24.07 testing here. Looks like there is no support for HEIC image format in Plasma, hence Gwenview doesn’t open these images, and Digikam won’t import them either.
Do you plan to add HEIC/HEIF support to OMV? Or maybe there are existing community packages with it that I’m simply not aware of? Custom repo on ABF?
P.S.
HEIC is the format used by iPhones to store photos.
Unfortunately, we cannot legally support those formats in the core OS because the compression algorithm used there is under the control of the patent mafia. This is, by the way, why Crapple uses this nonstandard format instead of the technically superior JPEG-XL or AVIF formats - they’re not content with just selling super expensive devices, they also want to be paid for the permission to view photos made with them.
That said, you can install HEIC/HEIF support. Enable the “restricted” repositories, and install:
kf6-kimageformats-avif
qt-heic-image-plugin
qt-heic-image-plugin-qt5 [if you’re still using any qt5 applications]
libheif-gdk-pixbuf [if you’re using any gtk applications]
If you are on KDE Plasma 6, do not install qt-heic-image-plugin.
Support for heic/heif is included in KImageFormats. The correct package is kf6-kimageformats-heif from the restricted repo.
