public sealed class EllipseStylusShape : StylusShape

NameDescription

NameDescription
System_CAPS_pubpropertyHeight

Gets the height of the stylus.(Inherited from StylusShape.)

System_CAPS_pubpropertyRotation

Gets the angle of the stylus.(Inherited from StylusShape.)

System_CAPS_pubpropertyWidth

Gets the width of the stylus. (Inherited from StylusShape.)

NameDescription
System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

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));
