Hello Vinay,
Sorry for the delay with the answer.
If I got you right, you want to capture the content of the browser (the rendered HTML page) as image. Is this correct?
If so, we are planning to add this functionality sometime in the future, but there are no definite plans right now.
You may also check the JxCapture product (http://www.teamdev.com/jxcapture) for different capturing abilities.
Hope this helps,
Eugene
