示例

此示例演示如何使用 PolyBezierSegment 创建一系列曲线。

<Canvas Width="500" Height="100">
  <Path Stroke="Red" StrokeThickness="2">
    <Path.Data>
      <PathGeometry>
        <PathGeometry.Figures>
          <PathFigureCollection>

            <!-- The StartPoint specifies the starting point of the first curve. -->
            <PathFigure StartPoint="10,100">
              <PathFigure.Segments>
                <PathSegmentCollection>

                  <!-- The PolyBezierSegment specifies two cubic Bezier curves.
                   The first curve is from 10,100 (start point specified above)
                   to 300,100 with a control point of 0,0 and another control
                   point of 200,0. The second curve is from 300,100 
                   (end of the last curve) to 600,100 with a control point of 300,0
                   and another control point of 400,0. -->
                  <PolyBezierSegment Points="0,0 200,0 300,100 300,0 400,0 600,100" />
                </PathSegmentCollection>
              </PathFigure.Segments>
            </PathFigure>
          </PathFigureCollection>
        </PathGeometry.Figures>
      </PathGeometry>
    </Path.Data>
  </Path>
</Canvas>

构造函数

PolyBezierSegment()

初始化 PolyBezierSegment 类的新实例。

属性

Dispatcher

始终在Windows 应用 SDK应用中返回 null 。 请改用 DispatcherQueue 。

(继承自 DependencyObject)
DispatcherQueue

获取 DispatcherQueue 与此 对象关联的 。 DispatcherQueue表示可以访问 DependencyObject UI 线程上的 的功能，即使代码是由非 UI 线程启动的。

(继承自 DependencyObject)
Points

获取或设置定义此 PolyBezierSegment 对象的 Point 集合。
PointsProperty

标识 Points 依赖属性。

方法

ClearValue(DependencyProperty)

清除依赖属性的本地值。

(继承自 DependencyObject)
GetAnimationBaseValue(DependencyProperty)

返回为依赖属性建立的任何基值，该基值适用于动画未处于活动状态的情况。

(继承自 DependencyObject)
GetValue(DependencyProperty)

从 DependencyObject 返回依赖属性的当前有效值。

(继承自 DependencyObject)
ReadLocalValue(DependencyProperty)

如果设置了本地值，则返回依赖属性的本地值。

(继承自 DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)

注册一个通知函数，用于侦听此 DependencyObject 实例上特定 DependencyProperty 的更改。

(继承自 DependencyObject)
SetValue(DependencyProperty, Object)

设置 DependencyObject 上依赖属性的本地值。

(继承自 DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)

取消以前通过调用 RegisterPropertyChangedCallback 注册的更改通知。

(继承自 DependencyObject)
