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. -->
                  <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>

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。
