RMagick VS imagemagick-aws-lambda-2

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.

I wanted to make this guide because while doing all of this process it's been really hard to find information. All the guides I found rely on this layer repository that it's not even updated anymore. I believe having the option to install whatever version of ImageMagick and libraries you want is better. So I hope this helps someone in the future.
