I always found it fascinating the grade-A executable names which imagemagick was able to claim in the global namespace:

    imagemagick /usr/bin/animate
    imagemagick /usr/bin/compare
    imagemagick /usr/bin/composite
    imagemagick /usr/bin/conjure
    imagemagick /usr/bin/convert
    imagemagick /usr/bin/display
    imagemagick /usr/bin/identify
    imagemagick /usr/bin/import
    imagemagick /usr/bin/mogrify
    imagemagick /usr/bin/montage
    imagemagick /usr/bin/stream

At my $OLDJOB, I used ImageMagick to compare snapshots during some automated front-end testing on our public Drupal site. It would compare the running test to previously accepted images, highlighting pixel diffs in red. It would also generate a 4 frame animated gif with of the original, highlit changes, the running test version, and back to the highlit changes (so it could loop for better comparison). Imagemagick sav…

Thanks for sharing this tip! Are there any guides you recommend?

Edit: Here’s one guide for the legacy Imagemagick (may not work for the latest release), https://legacy.imagemagick.org/Usage/compare/

I’m trying to encourage my front end developers to use visual diffs to validate rendering rather than use Protractor to test HTML/CSS.

I’ve known about BackstopJS, https://garris.github.io/BackstopJS/ and am on the lookout for alternatives.

Are there any [e]books focusing on ImageMagick? I use it a good deal, but it's one of those things where you _know_ you're under-utilizing it, and I'd like to take a deep dive with examples and sage wisdom attached.

Totally agree with this. The documentation is very mid-1990's, and every now and then I'll see a fork to it doing something bonkers that I didn't know was in there.

This is something I always preferred about the graphicsmagick fork, was the `gm` base command.

import is the most fun, when you forgot the `#!/usr/bin/env python` at the start of the script and of course the first instruction is import and you get an ImageMagik error

They are pretty common verbs, but they give 0 context to the user on what they do. I don't think these names are in any demand -- there's always a better name than "import" for your command line utility.

This appears to just go to the the script page of imagemagick.org. Is there something new or something else we should be looking at here?

For each thing "everyone knows," there are tons of people learning about it for the first time right now . https://xkcd.com/1053/

It's definitely a point worth remembering. I sometimes think about AWS's one year free tier offerings and think.. WTF doesn't have an AWS account and would still be signing up in 2021? In reality it's probably a lot of people.

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