Installation

Go set up the image_optim external utilities, then;

Middleman < 4.0

gem 'middleman-imageoptim'

Middleman ≥ 4.0

gem "middleman-imageoptim", :git => "https://github.com/plasticine/middleman-imageoptim", :branch => "master"

Usage

activate :imageoptim

You can also configure the extension in the usual fashion, by passing a block to :activate Below is the default configuration showing all available options;

activate :imageoptim do |options|
  # Use a build manifest to prevent re-compressing images between builds
  options.manifest = true

  # Silence problematic image_optim workers
  options.skip_missing_workers = true

  # Cause image_optim to be in shouty-mode
  options.verbose = false

  # Setting these to true or nil will let options determine them (recommended)
  options.nice = true
  options.threads = true

  # Image extensions to attempt to compress
  options.image_extensions = %w(.png .jpg .gif .svg)

  # Compressor worker options, individual optimisers can be disabled by passing
  # false instead of a hash
  options.advpng    = { :level => 4 }
  options.gifsicle  = { :interlace => false }
  options.jpegoptim = { :strip => ['all'], :max_quality => 100 }
  options.jpegtran  = { :copy_chunks => false, :progressive => true, :jpegrescan => true }
  options.optipng   = { :level => 6, :interlace => false }
  options.pngcrush  = { :chunks => ['alla'], :fix => false, :brute => false }
  options.pngout    = { :copy_chunks => false, :strategy => 0 }
  options.svgo      = {}
end
