SineEase 類別

定義

代表建立動畫之 easing 函式,其使用正弦公式來加速和/或減速。

範例

這個 XAML 範例會將 SineEase easing 函式套用至 DoubleAnimation ,以建立遞減動畫。

<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>
                    <SineEase 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

備註

SineEase 是一種 Easing 函式,其具有與函數時間圖表表示時類似正弦曲線的函式。 當 EasingModeEaseIn (預設) 時,此 Easing 函式會啟動緩慢,並在到達結尾時逐漸加速。 在持續時間的一半達到大約 30% 的值。

用於此函式的公式為:

f (t) 等於 1 減 sin 次, (1-t) 次 Pi 超過 2

Easing 函式可以套用至From/To/By動畫的EasingFunction屬性,或套用至用於主要畫面格動畫 Easing 變體之主要畫面格類型的EasingFunction屬性。 如需詳細資訊,請參閱 主要畫面格動畫和 Easing 函式動畫
