Additional information from upstream at https://imagemagick.org/discourse-server/viewtopic.php?t=36287 suggests it was disabled because of something in ghostscript 9.26
I think buster already has 9.27 from security so I think we could update the imagemagick default configuration. Is there good reason not to? Thanks, -- MJR http://mjr.towers.org.uk/ Member of http://www.software.coop/ (but this email is my personal view only)
