Middleman Thumbnailer

Generate thumbnail versions of your jpeg & png images

Installation

Add this line to your Gemfile:

gem 'middleman-thumbnailer', '~> 0.1'

Configuration

To activate generating thumbnails add the following to config.rb:

  activate :thumbnailer,
    :dimensions => {
      :small => '200x',
      :medium => '400x300'
    },
    :include_data_thumbnails => true,
    :namespace_directory => %w(gallery)

This activates the extension and will only process images in source/images/gallery.

For a file called background.png, versions named background-small-200x.png and background-medium-400x300.png will be generated in the same directory.

Config Options

• :include_data_thumbnails: Boolean (Default: false) - Enables including a list all image versions generated as the data-thumbnails-attribute for each image when using the thumbnail() helper

• :namespace_directory: Array (Default: nil) only process images found within this directory within source/images

Helpers

• thumbnail(image, size, [html_options]): returns thumbnail a image tag for image in size
• thumbnail_url(image, size): returns the url for image in size
