Detect actual size of HTML content in the WebBrowser control

Question

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.

Answer 1

I believe you can get it from the following property:

myWebBrowser.Document.ScrollRectangle.Size;

Being a System.Drawing.Size object.

Answer 2

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.
