I got some photos in HEIC format (which appears to be common in the Apple world) and ... nothing I had on my notebook could open them.

GIMP seems to happily handle those.

eog (GNOME image viewer) and magick (ImageMagick) - no luck.

libheif1-1.10.0-11.1.x86_64 is installed on this Tumbleweed system.

-> How do we get eog to process HEIC images?

-> Corollary: is there some other tool that converts those to JPEG/PNG?

Thank you, Gerald

Hi Gerarld, I ran into the same issue as well. Apparently it's possible to convert photos from HEIC to something else like .png using ImageMagick, but I don't think ImageMagick is compiled with the appropriate flags to enable this. When I try to convert a HEIC file to PNG I run into the following: $ magick convert image.heic image.jpg convert: no decode delegate for this image format `HEIC' @ error/constitute.c/ReadImage/572. convert: no images defined `image.jpg' @ error/convert.c/ConvertImageCommand/3301. The `identify` tool on my machine doesn't list HEIC as a supported format. $ identify -list format Format Module Mode Description - ----------------------------------------------------------------------- - -------- 3FR DNG r-- Hasselblad CFV/H3D39II 3G2 VIDEO r-- Media Container 3GP VIDEO r-- Media Container AAI* AAI rw+ AAI Dune image AI PDF rw- Adobe Illustrator CS2 APNG VIDEO rw+ Animated Portable Network Graphics ART* ART rw- PFS: 1st Publisher Clip Art ARW DNG r-- Sony Alpha Raw Image Format ASHLAR* ASHLAR -w+ Image sequence laid out in continuous irregular courses AVI VIDEO r-- Microsoft Audio/Visual Interleaved AVS* AVS rw+ AVS X image BGR* BGR rw+ Raw blue, green, and red samples BGRA* BGR rw+ Raw blue, green, red, and alpha samples BGRO* BGR rw+ Raw blue, green, red, and opacity samples BIE* JBIG rw- Joint Bi-level Image experts Group interchange format (2.1) BMP* BMP rw- Microsoft Windows bitmap image BMP2* BMP rw- Microsoft Windows bitmap image (V2) BMP3* BMP rw- Microsoft Windows bitmap image (V3) BRF* BRAILLE -w- BRF ASCII Braille format CAL* CALS rw- Continuous Acquisition and Life-cycle Support Type 1 Specified in MIL-R-28002 and MIL-PRF-28002 CALS* CALS rw- Continuous Acquisition and Life-cycle Support Type 1 Specified in MIL-R-28002 and MIL-PRF-28002 CANVAS* XC r-- Constant image uniform color CAPTION* CAPTION r-- Caption CIN* CIN rw- Cineon Image File CIP* CIP -w- Cisco IP phone image format CLIP* CLIP rw+ Image Clip Mask CMYK* CMYK rw+ Raw cyan, magenta, yellow, and black samples CMYKA* CMYK rw+ Raw cyan, magenta, yellow, black, and alpha samples CR2 DNG r-- Canon Digital Camera Raw Image Format CR3 DNG r-- Canon Digital Camera Raw Image Format CRW DNG r-- Canon Digital Camera Raw Image Format CUBE* CUBE r-- Cube LUT CUR* ICON rw- Microsoft icon CUT* CUT r-- DR Halo DATA* INLINE rw+ Base64-encoded inline images DCM* DCM r-- Digital Imaging and Communications in Medicine image DICOM is used by the medical community for images like X- rays.
