The GetIncrementalStrokeHitTester method returns an IncrementalStrokeHitTester that considers a Stroke to be "hit" when the eraser path intersects it. This is useful for implementing features, such as the ability to erase part of a Stroke. The InkCanvas uses an IncrementalStrokeHitTester when the EditingMode property is set to EraseByPoint.
The following example demonstrates how to get an IncrementalStrokeHitTester that can be used to erase part of a Stroke. To create a control that enables a user to erase ink, see How to: Erase Ink on a Custom Control.
