Photograph solves the issue of generating previews or thumbnails of web-based documents. Think of generating a preview of a Google Spreadsheet. As a such document is dom based, it may be difficult to get a preview that truly reflects the original content.
Photograph solves that problem by firing a chrome instance thanks to capybara-webkit and sinatra to provides an easy way to interface it to your needs.
Obviously, it supports cropping to avoid reworking the image afterward.
Please remind that having a chrome instance, even if it is being reused by all requests is still taking some time, aroung 600ms after the first request on my development machine. Consider using photograph only if you expect the same exact rendering of your 'web documents'.
Add this line to your application's Gemfile:
gem 'photograph'
And then execute:
$ bundle
Or install it yourself as:
$ gem install photograph
Photograph can be used either directly through the Photograph::Artist class or by its little sinata app.
@artist = Photograph::Artist.new("http://github.com")
@artist.shoot!
@artist.image
# => MiniMagick instance you can toy with
Or
$ bundle exec photograph -h 127.0.0.1 -p 4567
