The StylusShape specifies the shape, width, and height of the tip of a stylus. Methods such as Erase(Point(), StylusShape) and HitTest(Point(), StylusShape) 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.


' Prepare to collect stylus packets. Get the 
' IncrementalHitTester from the InkPresenter's 
' StrokeCollection and subscribe to its StrokeHitChanged event.
Protected Overrides Sub OnStylusDown(ByVal e As StylusDownEventArgs)

    MyBase.OnStylusDown(e)

    Dim eraserTip As New EllipseStylusShape(3, 3, 0)
    eraseTester = presenter.Strokes.GetIncrementalStrokeHitTester(eraserTip)
    AddHandler eraseTester.StrokeHit, _
        AddressOf eraseTester_StrokeHit
    eraseTester.AddPoints(e.GetStylusPoints(Me))

End Sub 'OnStylusDown
