Examples
The following example demonstrates how to create an EllipseStylusShape 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 enables 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 override void OnStylusDown(StylusDownEventArgs e)
{
base.OnStylusDown(e);
EllipseStylusShape eraserTip = new EllipseStylusShape(3, 3, 0);
eraseTester =
presenter.Strokes.GetIncrementalStrokeHitTester(eraserTip);
eraseTester.StrokeHit += new StrokeHitEventHandler(eraseTester_StrokeHit);
eraseTester.AddPoints(e.GetStylusPoints(this));
}
' Prepare to collect stylus packets. Get the
' IncrementalHitTester from the InkPresenter's
