StylusShape Class
Assembly: PresentationCore (in presentationcore.dll)
XML Namespace: http://schemas.microsoft.com/winfx/2006/xaml/presentation
The StylusShape specifies the shape, width, and height of the tip of a stylus. Methods such as Erase and HitTest use a StylusShape to determine the stylus tip of the hitting stroke. The EllipseStylusShape and RectangleStylusShape classes inherit from StylusShape.
The following example demonstrates how to create a StylusShape and pass it to the GetIncrementalStrokeHitTester method to erase a portion of a Stroke. This example assumes that there is a IncrementalStrokeHitTester called eraseTester and that its StrokeHit event has been connected to the event handler defined in this example. To create a control that allows a user to erase ink, see How to: Erase Ink on a Custom Control.
