Take screenshot from WPF

Is it possible to take screenshot of the single element on WPF form? I need to take screenshot of a开发者_如何转开发 "border" tool and its child.

considering source to be the element that you want to take a screenshot. This is the code that I have which saves it to the clipboard.

        RenderTargetBitmap bmp = new RenderTargetBitmap((int)source.ActualWidth, (int)source.ActualHeight, 96, 96, PixelFormats.Pbgra32);
        bmp.Render(source);
        Clipboard.SetImage(bmp);

You can use RenderTargetBitmap to render visuals, if you search for it on SO there should be some questions that help if the reference is not enough.
