示例

以下示例将缓动函数应用于 BackEase ， DoubleAnimation 以创建在动画开头和结尾稍稍回退的动画。

<Rectangle Name="MyRectangle" Margin="60" Width="50" Height="50" Fill="Blue">
      <Rectangle.Triggers>
          <EventTrigger RoutedEvent="Rectangle.MouseDown">
              <BeginStoryboard>
                  <Storyboard>
                      <DoubleAnimation From="1" To="2" Duration="00:00:1" 
                     Storyboard.TargetName="myScaleTransform" 
                     Storyboard.TargetProperty="ScaleX">
                          <DoubleAnimation.EasingFunction>
                              <BackEase Amplitude="0.3" EasingMode="EaseInOut" />
                          </DoubleAnimation.EasingFunction>
                      </DoubleAnimation>
                      <DoubleAnimation From="1" To="2" Duration="00:00:1" 
                     Storyboard.TargetName="myScaleTransform" 
                     Storyboard.TargetProperty="ScaleY">
                          <DoubleAnimation.EasingFunction>
                              <BackEase Amplitude="0.3" EasingMode="EaseInOut" />
                          </DoubleAnimation.EasingFunction>
                      </DoubleAnimation>

                  </Storyboard>
              </BeginStoryboard>
          </EventTrigger>
      </Rectangle.Triggers>
      <Rectangle.RenderTransform>
          <ScaleTransform x:Name="myScaleTransform" />
      </Rectangle.RenderTransform>

  </Rectangle>

注解

依赖属性标识符字段： AmplitudeProperty

振幅越大，动画之前和/或之后的回退幅度就越大。

XAML 属性用法
