CaptureImage

It's create the image of given url, uses Phantomjs at backend to create image http://phantomjs.org/

Add this line to your application's Gemfile:

gem 'capture_image'

And then execute:

$ bundle

Or install it yourself as:

$ gem install capture_image

Just create the form_tag and pass the url as text_field i.e.

<%=form_tag ( { controller: "home", action: "capture_image" } ) do%>
  <%= text_field_tag "url", nil %>
  <%= submit_tag :create%>
<%end%>

Pass the url to Rack via action to create the image

req = Rack::Request.new(params[:url])
req.params[:url] = url

it uses the middleware at backend to capture image so if you want to handle the request according to your functionality then you can edit the middleware.
