the latest versions recommend that you use magick convert instead of just convert. I'm assuming because the globals are going away.

"convert" always gave me trouble on Windows with some existing tools that used Windows' built in "convert" tool. It was an edge case, but always entertaining when the tool needed to convert a filesystem or some tool I wrote wanted to convert an image, and got the wrong executable.

I did a project where I scanned a bunch of old media. The scans where so high quality that it was impractical to make a PDF for people to use. The Imagemagick community helped out with the right incantation to make everything just kinda work. One of the rare cases where a project's maintainers will just help you use it. I was wowed.

If you ever need something actually performant or that uses far less memory, have a look at libVIPS

There are 634 CVE Records that match your search. https://cve.mitre.org/cgi-bin/cvekey.cgi?keyword=imagemagick There have been a number of zero days. My entire interaction with Imagemagick has been removing it. Often with great difficulty because there is some odd dependency.

Imagemagick is one of the few bits of software where the functionality is worth the risk. Simply find a way to remove any network access and use it. I used to run it in a docker container with (almost) all capabilities dropped but with a directory mapped into it to run.

ImageMagick, ffmpeg, exiftool and YouTube-dl are 4 of the most useful tools via command line.

I suppose it's probably a good idea to wrap it in a microservice in production.

Airgapped computer, it's the only way to be sure.

Printer output?

Same. I've successfully moved all my image manipulation requirements to libVIPS. Far more performant and with a ton less memory usage.

If executable names were traded like internet domains, imagine what they'd be worth now.

This is really interesting. In the past I've used netpbm for this kind of work, but it has been on life support for at least a decade now. I never used ImageMagick very much because each time I tried I found a new and exciting crash bug somewhere in the path, plus it tended to be much slower.
