Exemplos

O exemplo seguinte demonstra como usar um RectangleStylusShape para realizar testes de acerto num StrokeCollection. Este exemplo assume que existe um InkPresenter chamado presenter.

private void HitTestWithEraser(Point[] points)
{
    RectangleStylusShape eraser = new RectangleStylusShape(3, 3, 0);

    StrokeCollection strokes = presenter.Strokes.HitTest(points, eraser);

    foreach (Stroke s in strokes)
    {
        s.DrawingAttributes.Color = Colors.Purple;
    }
}

Private Sub HitTestWithEraser(ByVal points() As Point)
    Dim eraser As RectangleStylusShape = New RectangleStylusShape(3, 3, 0)

    Dim strokes As StrokeCollection = presenter.Strokes.HitTest(points, eraser)

    Dim s As Stroke
    For Each s In strokes
        s.DrawingAttributes.Color = Colors.Purple
    Next
End Sub
