Examples

The following code example iterates through stylus points of the strokes drawn in the first InkPresenter control to display its mirror image in the second InkPresenter control.

    Private MyStroke As Stroke

    Public Sub New()
        MyBase.New()
        InitializeComponent()

    'A new stroke object, MyStroke, is created and is added to the StrokeCollection object
    'of the InkPresenter, MyIP1

        Dim MyStylusPointCollection As StylusPointCollection = New StylusPointCollection
        MyStylusPointCollection.Add(e.StylusDevice.GetStylusPoints(MyIP1))
        MyStroke = New Stroke(MyStylusPointCollection)
        MyIP1.Strokes.Add(MyStroke)
    End Sub

    'StylusPoint objects are collected from the MouseEventArgs and added to MyStroke
    Private Sub MyIP1_MouseMove(ByVal sender As Object, ByVal e As MouseEventArgs)
        If (Not (MyStroke) Is Nothing) Then
