O exemplo a seguir demonstra como criar um EllipseStylusShape e passá-lo para o GetIncrementalStrokeHitTester método para apagar uma parte de um Stroke. Este exemplo pressupõe que há um IncrementalStrokeHitTester chamado eraseTester e que seu StrokeHit evento foi conectado ao manipulador de eventos definido neste exemplo. Para criar um controle que permite que um usuário apague a tinta, consulte Como apagar tinta em um controle personalizado.
