Is it possible to use GraphicsMagick for Dokuwiki as well?
Background: We're running nextcloud on our server, and it seems to have security trouble with Imagick and therefore they advise GraphicsMagick now (see https://github.com/nextcloud/server/issues/13099, which is two years old, but still valid - they also give you a hard time if you try ImageMagick anyway, but not so with GraphicsMagick).
By default, Dokuwiki uses GD
If I remember correctly, GraphicsMagick has compatibility option where it will accept exactly the same parameters as ImageMagick. Just configure the path to that equialent to IM's convert.
