  • Hello Pallam,

    This is a limitation for RenderTargetBitmap.RenderAsync to working with InkCanvas:

    See Rob's answer from here 

    “The rendered content needs to be in the main window's visual tree.” So that is why canvas cannot be used by this method.

    The alternate way to do this is to use Win2D

    Here is a simple document about it:

    Note, since you haven't tagged your question I'm not sure about your project type. Please notice the above method is only supported in Windows 10. 

    By the way, you can also search with your favorite search engine with this key word "Windows 10, UWP, InkCanvas and RenderTargetBitmap". There is a good blog about how you can do it with InkCanvas.
