## Installation

Go set up the [image_optim](https://github.com/toy/image_optim) external utilities, then;

```ruby
gem "middleman-imageoptim", "~> 0.1.3"
```

## Usage

```ruby
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;

```ruby
activate :imageoptim do |options|
  # print out skipped images
  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)

  # compressor worker options, individual optimisers can be disabled by passing
  # false instead of a hash
  options.pngcrush_options  = {:chunks => ['alla'], :fix => false, :brute => false}
  options.pngout_options    = {:copy_chunks => false, :strategy => 0}
  options.optipng_options   = {:level => 6, :interlace => false}
  options.advpng_options    = {:level => 4}
  options.jpegoptim_options = {:strip => ['all'], :max_quality => 100}
  options.jpegtran_options  = {:copy_chunks => false, :progressive => true, :jpegrescan => true}
  options.gifsicle_options  = {:interlace => false}
end
```
