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.
