I tried treating the full-size images with ImageMagick on the command line and then letting Hugo resize the result, but I wasn't happy with the output -- there's still way too much data in a dithered full-sized image, so when you scale it down, it just looks like a crappy black-and-white photo. Furthermore, the encoding wasn't properly optimizing for two-color images and so the files were larger than I wanted.

I made a [standalone image server][13] using [Sinatra][14] and [MiniMagick][15] that takes a path to an encrypted image and an optional geometry string and returns a dithered image.

This was super fun to build, and I'm really happy with [the result][20]. It makes the local authoring and deploy processes a bit more complicated since we have to run the separate image server, but I think the result is worth it. Hope you found this interesting, and please [reach out](mailto:hello@davideisinger.com) if you have any thoughts or questions. This was super fun to build, and I'm really happy with [the result][21].

This totally works, and I'll say that it's uniquely satisfying to save a document and see the link numbers get instantly reordered properly. I've done it probably 100 times in the course of writing this post.
