magick-wasm VS RMagick

Just a heads up, the official package is @imagemagick/magick-wasm, and the homepage is here: https://github.com/dlemstra/magick-wasm

I've not tried it (yet) but the ImageMagick folks list a WASM interface for the library, which means this functionality could (in theory) be done client-side (in the browser) without the need to deal with any API stuff.

require 'rmagick' include Magick module LambdaFunction class Handler def self.process(event:, context:) image_url = event['image_url'] my_image = ImageList.new(image_url) # TODO: Use rmagick to make your image transformations # Docs: https://rmagick.github.io { "success": true } end end end

mini_magick is much slower than YOLO. I hear that rmagick is well maintained these days, so you may want to use that.

To accomplish this project, I knew I would need some way to process the input images. Resizing the images was the easy bit. The more complex (and more important) task was to find the best way to relate a pixel's color in the source image to a dot's size in final animation. I felt that the relative luminance as described in this W3 accessibility document was a logical property to use in this case, and can be easily calculated with a color's RGB components. After determining what tasks I needed to fulfill, I determined that the RMagick library would be a good choice for this project.
