Selenium Webdriver take screenshot of viewport only

Question

Answer 1

This is a frequently changing issue..

AFAIK right now Chrome- and IEDriver both capture screenshots of the viewport only, while FFDriver captures a full-page screenshot (FF will change this in the future). See also my answer to this question.
