Examples

The following code example uses the StylusPoints property to iterate 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()
        SetBoundaryForIP1()
        SetBoundaryForIP2()
    End Sub

    'A new stroke object, MyStroke, is created and is added to the StrokeCollection object
    'of the InkPresenter, MyIP1
    Private Sub MyIP1_MouseLeftButtonDown(ByVal sender As Object, ByVal e As MouseEventArgs)
        MyIP1.CaptureMouse()
        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
            MyStroke.StylusPoints.Add(e.StylusDevice.GetStylusPoints(MyIP1))
        End If
    End Sub

    'MyStroke is completed
    Private Sub MyIP1_LostMouseCapture(ByVal sender As Object, ByVal e As MouseEventArgs)
        MyStroke = Nothing
    End Sub

    'Create the mirror image of the stroke collection in MyIP1 and adding it to MyIP2

            StylusPoint newpoint = new StylusPoint();
            newpoint.X = MyIP1.ActualWidth - p.X;
