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 saved enormous amounts of time for us as we made CSS and other module upgrades.

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.

Likely this came about from a reader of a recent post also on the front page [1] where image scaling is mentioned for website loading performance.

I notice this pattern. Someone posts, readers look at the article / content and the comments, then find something else interesting, and that thing then becomes another submission to HN (either because it is indeed interesting on its own, or to gain points due to relevancy of surrounding material on the front page, or both).

I don't know about using a CLI to edit images, but one of the best thing of having imagemagick installed on my workstation (it's an absolute essential) is the 'mogrify' CLI tool to batch resize, manipulate or change formats of a whole directory full of images.
