Set PhantomJS to capture entire screen after using clipRect()

Question

After doing setting page.clipRect followed by page.render, how can you disable clipRect so that subsequent page renders are of the entire viewport?

page.clipRect = {top:0, left:0, height: 10, width: 10} ;
page.render('screencap.png');  // cropped image

page.clipRect = '';
page.render('fullscreen.png');  // still cropped image!

Answer 1

Simply reset all values for clipRect:

page.clipRect = { left:0, top:0, width:0, height:0 }

then PhantomJS will recapture the entire content again.
