EllipseStylusShape Constructors

Definition

Namespace:

System.Windows.Ink

Assembly:

PresentationCore.dll

Initializes a new instance of the EllipseStylusShape class.

Overloads

EllipseStylusShape(Double, Double)	Initializes a new instance of the EllipseStylusShape class with the specified width and height.
EllipseStylusShape(Double, Double, Double)	Initializes a new instance of the EllipseStylusShape class with the specified width, height, and angle.

Remarks

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));
}
