ROM VS ruby-vips

Object Mapper: rom-rb/rom: Data mapping and persistence toolkit for Ruby

Just wanted to say that the authors libraries, especially ROM [0], are incredible and have played a huge influence on me as a developer. I learned a lot using and diving through the code.

[0]: https://rom-rb.org/

Better gems. dry-rb, ROM, and Hanami are doing interesting stuff. I also hear web_pipe is popular?

This is exactly how I ended up contributing to DataMapper, then joining the core team, then releasing Virtus, then working on DataMapper 2.0, then turning it into rom-rb, then joining dry-rb and building 1.25 library / month on average for about 2 years or so to eventually join Hanami team...and, yeah, it's been kinda nuts now when I look back.

Ruby Object Mapper

I'm trying to add a watermark to images as they are uploaded before they're saved. I'm using the following code(borrowed heavily from the example here)

Photein uses Minimagick for image management and conversion. Have you had a look at ruby-vips? From what I hear it should be better/faster/use less memory than ImageMagick, especially for the standard image formats.

A special mention to ruby-vips, which is (along with maybe php, I guess) one of the few language bindings maintained by the author of libvips, which should become the defacto image processing manipulation library.
