示例

以下示例演示如何从 StylusPointCollection 和 DrawingAttributes 对象创建 Stroke 。 此示例假定有一个名为 InkPresenter 的 myInkPresenter。

DrawingAttributes drawingAttributes1 = new DrawingAttributes();
drawingAttributes1.Color = Colors.Green;

StylusPoint stylusPoint1 = new StylusPoint(100, 100);
StylusPoint stylusPoint2 = new StylusPoint(100, 200);
StylusPoint stylusPoint3 = new StylusPoint(200, 200);
StylusPoint stylusPoint4 = new StylusPoint(200, 100);
StylusPoint stylusPoint5 = new StylusPoint(100, 100);

StylusPointCollection points = new StylusPointCollection(
    new StylusPoint[] { stylusPoint1, stylusPoint2, stylusPoint3, 
                        stylusPoint4, stylusPoint5 });

Stroke newStroke = new Stroke(points, drawingAttributes1);

myInkPresenter.Strokes.Add(newStroke);

Dim drawingAttributes1 As New DrawingAttributes()
drawingAttributes1.Color = Colors.Green

Dim stylusPoint1 As StylusPoint = New StylusPoint(100, 100)
Dim stylusPoint2 As StylusPoint = New StylusPoint(100, 200)
Dim stylusPoint3 As StylusPoint = New StylusPoint(200, 200)
Dim stylusPoint4 As StylusPoint = New StylusPoint(200, 100)
Dim stylusPoint5 As StylusPoint = New StylusPoint(100, 100)

Dim points() As StylusPoint = {stylusPoint1, stylusPoint2, _
                    stylusPoint3, stylusPoint4, stylusPoint1}

Dim pointCollection As New StylusPointCollection(points)

Dim NewStroke As Stroke = New Stroke(pointCollection, drawingAttributes1)

myInkPresenter.Strokes.Add(NewStroke)

Stroke(StylusPointCollection, DrawingAttributes)

初始化 Stroke 类的新实例。

public:
 Stroke(System::Windows::Input::StylusPointCollection ^ stylusPoints, System::Windows::Ink::DrawingAttributes ^ drawingAttributes);

public Stroke (System.Windows.Input.StylusPointCollection stylusPoints, System.Windows.Ink.DrawingAttributes drawingAttributes);

new System.Windows.Ink.Stroke : System.Windows.Input.StylusPointCollection * System.Windows.Ink.DrawingAttributes -> System.Windows.Ink.Stroke

Public Sub New (stylusPoints As StylusPointCollection, drawingAttributes As DrawingAttributes)

参数

stylusPoints

StylusPointCollection

表示 StylusPointCollection 的 Stroke。

drawingAttributes

DrawingAttributes

DrawingAttributes 对象，用于指定 Stroke 的外观。

例外

ArgumentNullException

stylusPoints 为 null。

- 或 -

drawingAtrributes 为 null。

ArgumentException

stylusPoints 为空。
