Moul

Opinionated Image Resizing Library

Installation

This package requires a static binary, https://github.com/moul-co/moul/releases >= v5.0.0-rc.5 to be in $PATH.

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

def deps do
  [
    {:moul, "~> 0.4.0"}
  ]
end

There are two hashing options available:

• BlurHash https://github.com/woltapp/blurhash
• ThumbHash https://github.com/evanw/thumbhash

By default, moul uses ThumbHash, but it can also be configured to use BlurHash.

config :moul,
  hash: "blurhash"
