[Pkg-gmagick-im-team] Bug#914120: imagemagick: Enable HEIF/HEIC image format support

[Manfred Stock]

Source: imagemagick
Version: 8:6.9.10.14+dfsg-7
Severity: wishlist
Tags: patch

Dear Maintainer,

I noticed that the current ImageMagick packages don't support the HEIF/HEIC
image format [1], which seems like it is becoming more common, especially in
the Apple world, and therefore images in this format are popping up in the wild
more often now. It would thus be nice if the ImageMagick package in Debian
would support this format, particularly since the currently packaged version
has at least basic support for the format and the required dependencies are
already available in Debian (and used by Gimp and Krita as it seems).

The attached patch seemed to be sufficient to enable the support, using
packages built with the patch applied, I was able to convert example images
from eg. [2] (which can also be retrieved from [3]) to other formats or run
identify(1) on them, which was failing with
    identify-im6.q16: no decode delegate for this image format `HEIC' @ error/constitute.c/ReadImage/560.
before.

Kind regards
Manfred
