EllipseStylusShape Class

Represents an elliptical stylus tip.

Namespace: System.Windows.Ink
Assembly: PresentationCore (in presentationcore.dll)
XML Namespace:  http://schemas.microsoft.com/winfx/2006/xaml/presentation

public sealed class EllipseStylusShape : StylusShape
public final class EllipseStylusShape extends StylusShape
public final class EllipseStylusShape extends StylusShape
You cannot use this managed class in XAML.

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 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 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));

}
