Silverlight图像翻转动画
Silverlight图像翻转动画
提问于 2011-12-08 05:51:23
在我的silverlight应用程序中，我有两个尺寸相同的图像。
当用户单击图像时，我希望将一个图像转换为另一个图像的动画，就像翻转一张纸一样，第一张图像在正面，另一张在背面。
我还没有使用过silverlight动画，所以我不知道从哪里开始。

基本上，你一开始需要两个Storybards。每个Storyboard都将使用PlaneProjection (在本例中，我使用的是RotationX，它可以围绕x轴旋转图像)来制作翻转动画。
在下面的示例中，我创建了FlippingDown和FlippingUp两个Storyboards。我给它们每一个附加了一个ControlStoryboardAction行为，它们将在MouseLeftButtonDown被触发时被触发。
您需要引用System.Windows.Interactivity和Microsoft.Expression.Interactions。

您可以在Blend中搜索有关投影动画的信息。这看起来就是您需要的：http://www.silverlightbuzz.com/2009/10/14/using-the-3d-tools-to-animate-in-blend/
