title: Take a screenshot of an entire webpage using Robot Framework
body: <p>I have a problem on taking a screenshot using robotframework.</p>
  
  <p>Currently I am using keyword Capture Page Screenshot on Selenium2library. The problem is that, keyword only captures the webpage visible on the screen.
  We needed a screenshot that could take the entire webpage. This means that when it capture a screenshot it should scroll down to the bottom of the webpage and capture the whole page. Is that possible?</p>
  
  <p>Appreciate everyone can suggest if there are other library that we  can use.</p>
