How to convert an html webpage to a picture

Question

How to convert an html webpage to a picture like google preview.

Is there a Java library permitting this?

Is there a command-line argument to call browsers to make them convert a web page into a picture .png for instance?

Using Qt, you can create a simple window with a QWebView (this is webkit under the covers), and then use QWidget::render() method to get QPixmap, and then convert it to QImage.

Qt is C++, but python and java bindings exist also.
