How to take screenshot of a website with Rails 3.1? — without using a service

Question

Almost every answer I\'ve found references using some existing service. Is there a way to do this using Rails 3.1 programmatically? This was dead easy to do wit

Answer 1

There is a Rails gem for this task.

 gem install selenium-webdriver

Simple use case:

require 'selenium-webdriver'
 width = 1024
 height = 728
 driver = Selenium::WebDriver.for :firefox
 driver.navigate.to 'http://domain.com'
 driver.execute_script %Q{
   window.resizeTo(#{width}, #{height});
 }
 driver.save_screenshot('/tmp/screenshot.png')
 driver.quit
