Created ImageMagick tracking bugs for this issue:

Affects: fedora-all [bug 1610622]

Comment 3 Stefan Cornelius 2018-08-02 11:01:18 UTC
RHEL does not have this function. Upstream has it since https://github.com/ImageMagick/ImageMagick6/commit/e806bc5559474b19114faf235266dbb8f6b206ee

Comment 4 Stefan Cornelius 2018-08-02 11:01:28 UTC

This issue did not affect the versions of ImageMagick as shipped with Red Hat Enterprise Linux 5, 6, and 7.
