Smeargle

Smeargle is an image collection tool that will return an object containing images from a given URL. Smeargle was designed to be a lightweight and simple solution for collecting images.

This library does provide some basic logic for helping you find a suitable image from any given url. Smeargle uses rmagick for filtering images based on size.

Add this line to your application's Gemfile:

gem 'smeargle'

And then execute:

$ bundle

Or install it yourself as:

$ gem install smeargle

When initializing a smeargle object, you're able to provide a variety of options to help with image selection.

  # Initialize a collection with a minimum image width of 200
  Smeargle::Sketch.new 'http://mockra.com', min_width: 200

The available options are:

  Minimum images dimentions returned
  :min_width, :min_height

Images returned by your URL are included in the images array. Depending on the number of images included in the body, this could take some time to run. You may want to have it run in the background.

  s = Smeargle::Sketch.new 'google.com'

  # returns an array filtered by provided options
  s.images

  s.images.each do |img|
    img[:url]
    img[:width]
    img[:height]
  end

If you're not looking to filter images, and don't need detailed information, then you can use simple_images. This method returns an array of image urls, and is faster than the images method.

  s = Smeargle::Sketch.new 'google.com'

  s.simple_images.each do |img|
    img  # returns 'http://google.com/test.jpg'
  end
