QuarticEase 类
定义
重要
一些信息与预发行产品相关,相应产品在发行之前可能会进行重大修改。 对于此处提供的信息,Microsoft 不作任何明示或暗示的担保。
表示缓动函数,该函数使用公式 f (t) = t4 创建加速和/或减速的动画。

示例
此 XAML 示例将 QuarticEase 缓动函数应用于 DoubleAnimation 以创建减速动画。
<StackPanel x:Name="LayoutRoot" >
<StackPanel.Resources>
<Storyboard x:Name="myStoryboard">
<DoubleAnimation From="1" To="6" Duration="00:00:3"
Storyboard.TargetName="rectScaleTransform"
Storyboard.TargetProperty="ScaleY">
<DoubleAnimation.EasingFunction>
<QuarticEase EasingMode="EaseOut"/>
</DoubleAnimation.EasingFunction>
</DoubleAnimation>
</Storyboard>
</StackPanel.Resources>
<Rectangle PointerPressed="Pointer_Clicked"
Fill="Blue" Width="200" Height="30">
<Rectangle.RenderTransform>
<ScaleTransform x:Name="rectScaleTransform" />
</Rectangle.RenderTransform>
</Rectangle>
</StackPanel>
// When the user clicks the rectangle, the animation
// begins.
private void Pointer_Clicked(object sender, PointerRoutedEventArgs e)
{
myStoryboard.Begin();
}
' When the user clicks the rectangle, the animation
' begins.
Private Sub Pointer_Clicked(ByVal sender As Object, ByVal e As PointerRoutedEventArgs)
myStoryboard.Begin()
End Sub
注解
QuarticEase 的行为与 Power 值为 4 的 PowerEase 的行为相同。 当 EasingMode 为 EaseIn (默认) 时,此缓动函数启动缓慢,在大部分持续时间内保持相当缓慢,并在接近持续时间结束时快速加速。
缓动函数可应用于 From/To/By 动画的 EasingFunction 属性,或应用于用于关键帧动画缓动变体的关键帧类型的 EasingFunction 属性。 有关详细信息,请参阅 关键帧动画和缓动函数动画。
构造函数
QuarticEase() |
初始化 QuarticEase 类的新实例。 |
属性
Dispatcher |
获取与此 对象关联的 CoreDispatcher 。 CoreDispatcher 表示可以访问 UI 线程上的 DependencyObject 的工具,即使代码是由非 UI 线程启动的。 (继承自 DependencyObject) |
EasingMode |
获取或设置用于指定动画内插方式的值。 (继承自 EasingFunctionBase) |
方法
ClearValue(DependencyProperty) |
清除依赖属性的本地值。 (继承自 DependencyObject) |
Ease(Double) |
转换规范化时间以控制动画的节奏。 (继承自 EasingFunctionBase) |
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) |
