Detect actual size of HTML content in the WebBrowser control

Is there any way to detect the contents height/width in the WebBrowser control? I'd like to save the contents to an image but only at the size of the actual contents.

Thank you in advance.

loop elements select max height/width. i used this after documentCompleted event

    //fit to content  -get size **after documentCompleted**
    var wbAll = webBrowser.Document.All.Cast<HtmlElement>();
    var maxWidth = wbAll.Max(x => Math.Max(x.ClientRectangle.Width, x.ScrollRectangle.Width));
    var maxHeight =wbAll.Max(x => Math.Max(x.ClientRectangle.Height, x.ScrollRectangle.Height));

    webBrowser.Height = maxHeight;
    webBrowser.Width = maxWidth;

The document recalculate the layout each time the size of the browser window changes, so it does not really have a fixed size.

You can using a Golden section search to find the minimal window size large enough to contain the document, but it is a CPU-intensive task.

I believe you can get it from the following property:

myWebBrowser.Document.ScrollRectangle.Size;

Being a System.Drawing.Size object.
