Phashion VS RMagick

I've been using this in a Rails app to detect duplicate image uploads for years. It works really well.

https://github.com/westonplatter/phashion

I am the current maintainer (albeit, not a great one, but still a maintainer) the phashion ruby gem (https://github.com/westonplatter/phashion).

I was notified by a user that the current MIT license of phashion may conflict with the GPL 3.0 license of the pHash software included in it. The argument goes that since phashion includes the source code of pHash as apart of its distribution, it needs to also use the GPL 3.0 license.

My question ... is there a licensing conflict between phashion and pHash? If so, what are the options?

NOTE - I realize I'm asking a legal/IP question. I will not treat comments or opinions as legal advice.

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.
