你如何检索Windows上的手写笔压力信息？

<InkCanvas x:Name="inkCanvas" />

<InkCanvas x:Name="inkCanvas" StrokeInput="inkCanvas_StrokeInput" />

private void inkCanvas_StrokeInput(object sender, Windows.UI.Xaml.Ink.InkStrokeInputEventArgs e)
{
    var strokes = e.GetStrokes();
    foreach (var stroke in strokes)
    {
        var points = stroke.GetInkPoints();
        foreach (var point in points)
        {
            var pressure = point.Pressure;
            // 在这里处理手写笔的压力信息
        }
    }
}
