An InkCanvas is an element that can be used to receive and display ink input.

An InkCanvas is an element that can be used to receive and display ink input. This is commonly done through the use of a stylus, which interacts with a digitizer to produce ink strokes using a stylus or a mouse. The created strokes are represented as Stroke objects, and can be manipulated either programmatically or based on user input. The InkCanvas enables users to modify or delete an existing Stroke.

The InkCanvas can be bound to a data source. For example, you can bind the Strokes property to: a base-64, encoded string that contains ink data in Ink Serialized format (ISF); or even to the Strokes property of another InkCanvas. You can also bind properties, such as DefaultDrawingAttributes and EditingMode, to other data sources.
