ImageMagick is installed by default on the desktop with PureOS3 beta. This does not make sense.
Over the years I've had all the creative apps (Inkscape, GIMP, Krita, Scribus, Blender, MyPaint, Calligra, etc.) installed and I never saw ImageMagick installed, I didn't even know a GUI existed for it ;) so given that PureOS3 beta doesn't have any creative apps preinstalled, I don't see where this thing appeared from.
We have tools to find out why stuff is in the default install :-)
Admittedly, I haven't made any nice web UI for this yet:
--> ImageMagick is in there because cups-filters depends on it.
Both cups-filters and inkscape recommend imagemagick.
PureOS installs recommendations by default - you can remove them if you know they are not needed for your particular use case, but including imagemagick by default is not a bug.
