Snapa

Use this gem to render your page with phantomjs and take a png snapshot of the rendered body / css selector, usefull for generating an IE friendly version of an svg or html5 canvas. A map example is provided by passing :map to the initializer.

Add this line to your application's Gemfile:

gem 'snapa'

And then execute:

$ bundle

Or install it yourself as:

$ gem install snapa

To run as a stand alone rack app

config.ru
run Snapa::File.new('public/map.html')

To mount under Rails

config/routes.rb
mount Snapa::File.new('public/map.html') => '/map.png'

The default cache path is /tmp/snapa or public/system/snapa when mounted under a rails app. This can be overridden by passing an optional cache_path param to the initializer.
