Smartcropper Image Generator for Jekyll

This gem allows you to easily use SmartCropper and RMagick to crop and resize images in your Jekyll project, according to a preset defined in your config file.

Basic Setup

Install the gem:

[sudo] gem install jekyll-smartcropper

In a plugin file within your Jekyll project's _plugins directory:

# _plugins/my-plugin.rb
require "jekyll-smartcropper"

Define presets in your _config.yml file, like this:

# _config.yml
smartcropper:
    thumbnail:
        source: img/original
        destination: img/thumb
        process: "crop_and_scale"
        width: 100
        height: 100
    medium:
        source: img/original
        destination: img/medium
        process: "crop"
        width: 600
        height: 400

This configuration will create a 100x100 thumbnail for each image in img/original and put it in _site/img/photos/thumbnail and a 600x400 image in _site/img/photos/medium.

Bundler Setup

Already using bundler to manage gems for your Jekyll project? Then just add

gem "jekyll-smartcropper"

to your gemfile and create the following plugin in your projects _plugins directory. I've called mine bundler.rb. This will automatically require all of the gems specified in your Gemfile.

# _plugins/bundler.rb
require "rubygems"
require "bundler/setup"
Bundler.require(:default)
