範例
此範例示範如何使用 PolyBezierSegment 來建立一系列曲線。
<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. -->

建構函式
PolyBezierSegment() |
初始化 PolyBezierSegment 類別的新實例。 |
屬性
Dispatcher |
取得與此物件相關聯的 CoreDispatcher 。 CoreDispatcher代表可以存取 UI 執行緒上DependencyObject的功能,即使程式碼是由非 UI 執行緒起始也一樣。 (繼承來源 DependencyObject) |
Points |
取得或設定 Point 集合,這個集合會定義這個 PolyBezierSegment 物件。 |
PointsProperty |
識別 Points 相依性屬性。 |
方法
ClearValue(DependencyProperty) |
清除相依性屬性的本機值。 (繼承來源 DependencyObject) |
GetAnimationBaseValue(DependencyProperty) |
傳回針對相依性屬性所建立的任何基底值,如果動畫未使用中,則會套用。 (繼承來源 DependencyObject) |
GetValue(DependencyProperty) |
從 DependencyObject傳回相依性屬性的目前有效值。 (繼承來源 DependencyObject) |
ReadLocalValue(DependencyProperty) |
如果已設定本機值,則傳回相依性屬性的本機值。 (繼承來源 DependencyObject) |
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback) |
註冊通知函式,以接聽此DependencyObject實例上特定DependencyProperty的變更。 (繼承來源 DependencyObject) |
SetValue(DependencyProperty, Object) |
在 DependencyObject上設定相依性屬性的本機值。 (繼承來源 DependencyObject) |
UnregisterPropertyChangedCallback(DependencyProperty, Int64) |
取消先前透過呼叫 RegisterPropertyChangedCallback註冊的變更通知。 (繼承來源 DependencyObject) |
