EasyOptimise

A wrapper built on the Paperclip attachment gem. EasyOptimise adds the abililty to optimise image sizes for web using sane defaults for compression and quality. The image optimisation is applied using ImageMagick utility functions.

Installation

Add this line to your application's Gemfile:

gem 'easy_optimise'

And then execute:

$ bundle

Or install it yourself using Rubygems:

$ gem install easy_optimise

Usage

In paperclip you might:

has_attached_file :avatar, 
  styles: { medium: "300x300>",
            thumb:  "100x100>" },
  default_url: "/images/:style/missing.png"

With EasyOptimise, to optimise the images you serve up, just extend the gem in your model:

extend EasyOptimise

and then slip in one sneaky word in your attachment method:

has_attached_optimised_file :avatar,
  styles: { medium: "300x300>",
            thumb:  "100x100>" },
  default_url: "/images/:style/missing.png"

If you want to keep a particular style unoptimised for precise quality (or because you like big slow websites and that's just how you roll), then:

has_attached_optimised_file :avatar,
  styles: { medium: "300x300>",
            thumb:  "100x100>" },
  unoptimised_styles: { banner: "1200x800#" },
  default_url: "/images/:style/missing.png"
