Can't process HEIC files

[mikegilchrist]

ImageMagick version

7.1.2-3 Q16-HDRI x86_64 ea3338c:20250828

Operating system, version and so on

Mint MATE 24.04

Description

I am trying to convert and resize some HEIC files using for FILE in *HEIC; do magick $FILE -resize 1500x1298 -quality 100 Reduced/${FILE/HEIC/jpg}; done. I get the messages

magick: Invalid input: Unspecified: Too many auxiliary image references (2.0) `IMG_1710.HEIC' @ error/heic.c/IsHEIFSuccess/202.

I am using the AppImage version of magick. Can anyone help me understand what's going on?

It suspect that your file is hitting an internal security limit of the heic decoder. But I can only make guesses without the file.

Ugh. I seem to recall running into memory limits with earlier versions of imagemagick. I'm using the appimage. Am I correct to assume this is an internal imagemagick setting that I can't alter with the appimage or is this a limit in a library somewhere?

Try changing your policy.xml file. If you do not have enough memory, then use disk. See https://imagemagick.org/script/security-policy.php and https://imagemagick.org/script/architecture.php#tera-pixel

Thanks for the suggestion. I currently only have IM 6.9.12-98 installed on my system (IM 7 is an AppImage). I set threads to 4, memory to 4GiB, map to 2GiB, and disk to 8GiB (needed this one as well) and that solved the issue!

Have the same problem. Running wordpress web site and have a big problem with this apple s*its...
When try to run manualy on server "magick img_7076-1.heic output_test.jpg" got this error: magick: Invalid input: Unspecified: Too many auxiliary image references (2.0) `img_7076-1.heic' @ error/heic.c/IsHEIFSuccess/202..

On php output i see: ImageMagick version number 1810
ImageMagick version string ImageMagick 7.1.2-7 Q16-HDRI x86_64 23405 https://imagemagick.org

Works fine for me on IM 7.1.2.8 Mac OSX Ventura with libheif @1.19.8

Please show your OS and

magick -version

And check your libheif version with

magick -list format

it should show something like

     HEIC  HEIC      rw+   High Efficiency Image Format (1.19.8)
     HEIF  HEIC      rw+   High Efficiency Image Format (1.19.8)

Your version of libheif is old. Try upgrading. I am at 1.19.8 and the current version is 1.20.2-2.
