[REQUEST] HEIC support in ImageMagick

[gerdemb]

Would be nice if the ImageMagick supported HEIC files. Seems like libheif is already installed by Synology, so should just be a matter of getting ImageMagick to use it.

@gerdemb it is not as easy as linking to the already installed shared libraries.
But you can use imagemagick installed in the DSM system, as it was built with HEIC support:

$ which convert
/bin/convert

$ convert --version

I was already working on a imagemagick package update about a year ago. I added heic, wmf and other file formats (but not yet svg as per #3881). Maybe I find some spare time to complete this,

$ which magick
/usr/local/bin/magick

$ ls -l $(which magick)
lrwxrwxrwx 1 root root 41 Apr 26 07:20 /usr/local/bin/magick -> /volume1/@appstore/imagemagick/bin/magick

$ magick --version

The current synocommunity imagemagick package has only a few formats built in:

$ /var/packages/imagemagick/target/bin/magick --version

Thanks for your comment. Actually, I was trying to use the synocommunity ImageMagick package as I was having trouble getting the built-in Synology version (/bin/convert) to convert HEIC files.

Eventually, I discovered that Synology has released a new package called "Advanced Media Extensions", that has a working version of ImageMagick here:

$ ls -al /volume1/@appstore/CodecPack/usr/bin
total 48
drwxr-xr-x 2 root root 4096 Jan 20 00:33 .
drwxr-xr-x 4 root root 4096 Jan 20 00:33 ..
-rwxr-xr-x 1 root root 6264 Jan 20 00:33 compare
-rwxr-xr-x 1 root root 6240 Jan 20 00:33 composite
-rwxr-xr-x 1 root root 6240 Jan 20 00:33 convert
-rwxr-xr-x 1 root root 6248 Jan 20 00:33 identify
-rwxr-xr-x 1 root root 6240 Jan 20 00:33 montage

It seems the version left in /usr/bin/convert is broken for HEIC images.

Leaving this comment in the hope that it might help anyone else having the same problem.

@gerdemb you find pre-release packages here.

Please note that ARMv5 and old PPC Archs do not include the HEIC format (88f6281-6.1 and ppc853x-5.2)
