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
