Elxvips

Experimental Elixir bindings to libvips for image processing, since it’s supposed to be faster than GraphicsMagick/ImageMagick. It is based on the existing Rust bindings to libVips. To make it work you will require libVips. Please refer to Dockerfile for dependencies.

|> jpg( strip: true )
|> to_file( "output.jpg" )
{ :ok, %ImageFile{} }

The package can be installed by adding elxvips to your list of dependencies in mix.exs:

def deps do
  [
    {:elxvips, "~> 0.1.3"}
  ]
end

Precompiled NIFs

Since version 0.1.3 Elxvips comes with some precompiled nifs, and depends only on libvips.
