window

I'm writing a C# WPF application that creates a video capture of the active window. What I want to do is overlay a transparent .png file in the corner of the active window while a capture is in progress so that all the videos created by my application are watermarked.

If I have the IntPntr handle of the window I am capturing and an image file - what is the best way to go about this?

Thanks
