如何:对斜切可视化效果进行动画处理
更新:2007 年 11 月
本示例演示如何对按钮上的 BevelBitmapEffect 进行动画处理。
示例
下面的示例演示如何对 BevelBitmapEffect 的 BevelWidth 和 LightAngle 属性进行动画处理。因此,当鼠标指针移到 Button 上时,楔形的内部级别增加,同时用于楔形的人造光源将围绕着 Button 旋转。

<Button Width="200" Height="80" Margin="50">
MouseOver ME!
<Button.BitmapEffect>
<!-- This BitmapEffect is targeted by the animation. -->
<BevelBitmapEffect x:Name="myBevelBitmapEffect" BevelWidth="0" EdgeProfile="CurvedIn" />
</Button.BitmapEffect>

<EventTrigger RoutedEvent="Button.MouseEnter">

<!-- Animate the BevelWidth from 0 to 15. -->
<DoubleAnimation
Storyboard.TargetName="myBevelBitmapEffect"
Storyboard.TargetProperty="BevelWidth"
From="0" To="15" Duration="0:0:0.5" AutoReverse="True"
/>
<!-- Animate the LightAngle so that the light source and
corresponding bevel shadows move around the button. -->
<DoubleAnimation
Storyboard.TargetName="myBevelBitmapEffect"
Storyboard.TargetProperty="LightAngle"
From="360" To="0" Duration="0:0:0.5" AutoReverse="True"
/>
