The CopyFromScreen methods are useful for layering one image on top of another. The copyPixelOperation parameter allows you to specify if and how the source colors should be blended with the colors in the destination area.

The following example demonstrates how to use the CopyFromScreen method. To run this example, paste it into a Windows Form. Handle the form’s Paint event and call the CopyPixels2 method from the Paint event-handling method, passing e as PaintEventArgs.

Private Sub CopyPixels2(ByVal e As PaintEventArgs) 
    e.Graphics.CopyFromScreen(Me.Location, _
        New Point(40, 40), New Size(100, 100), _
End Sub
