title: perl Gtk2::WebKit: how to do a full page screenshot
body: <p>I'm using the perl module <a href="https://metacpan.org/pod/Gtk2%3a%3aWebKit" rel="nofollow"><code>Gtk2::WebKit</code></a> to create a browser and take a screenshot of a web page.  There is no problem to take a screenshot of the visible portion of the page (the window size).  However, how can I take a screenshot of the full page, even the part not visible in the window?</p>
