IncrementalStrokeHitTester.StrokeHit Event

Occurs when the IncrementalStrokeHitTester intersects an ink Stroke.

Namespace:  System.Windows.Ink
Assembly:  PresentationCore (in PresentationCore.dll)

public event StrokeHitEventHandler StrokeHit
You cannot use this event in XAML.

The following example demonstrates how to dynamically erase a portion of a Stroke. To create a control that enables a user to erase ink, see How to: Erase Ink on a Custom Control.

// When the stylus intersects a stroke, erase that part of 
// the stroke.  When the stylus dissects a stoke, the  
// Stroke.Erase method returns a StrokeCollection that contains 
// the two new strokes. 
void eraseTester_StrokeHit(object sender,
    StrokeHitEventArgs args)
{
    StrokeCollection eraseResult =
        args.GetPointEraseResults();
    StrokeCollection strokesToReplace = new StrokeCollection();
    strokesToReplace.Add(args.HitStroke);

    // Replace the old stroke with the new one. 
    if (eraseResult.Count > 0)
    {
        presenter.Strokes.Replace(strokesToReplace, eraseResult);
    }
    else
    {
        presenter.Strokes.Remove(strokesToReplace);
    }
