I'm doing complex html operations on images (drag & drop) and when I'm done, I need to take the screenshot of the page and get the taken image save it on server (virtual dir).

So what I need is

Image img = CaptureURL("www.a.com/b.aspx");

Does anyone know of a library that could help me do this?

Thank you

One solution is to use the WebBrowser control and render the result on a bitmap.

Here is the full solution, I think is simple and fast.

Other way is to use the IECapt that is a capture utility that can run on server and you can call it from your pages using the Process.Start.

here is the second solution.

And there is the javascript way, that your user render the page on the client side and send you the image. See some examples here : http://hertzen.com/experiments/jsfeedback/ and the source code is here: http://html2canvas.hertzen.com/

Hope this help
