Examples
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);
}
}
' When the stylus intersects a stroke, erase that part of
