Animate RenderTransformOrigin

Question

我想RenderTransformOrigin在xaml中修改storyboard.该值不能动画,立即更改也可以.以下代码不起作用:

<Storyboard x:Key="StoryboardFadeIn">
  <DoubleAnimation Storyboard.TargetProperty="(UIElement.RenderTransformOrigin).(Point.X)" Storyboard.TargetName="UserControl" To="0"/>
  <DoubleAnimation Storyboard.TargetProperty="(UIElement.RenderTransformOrigin).(Point.Y)" Storyboard.TargetName="UserControl" To="0"/>
</Storyboard>

是否可以在动画中更改此属性(仅使用xaml)？

错误代码:

The property "X" is not a DependencyProperty. To be used in markup, non-attached properties must be exposed on the target type with an accessible instance property "X".

我不确定你是否可以使用动画X和Y点结构动画DoubleAnimation,但你应该能够RenderTransformOrigin使用a 动画PointAnimation

例:

<Storyboard x:Key="StoryboardFadeIn">
    <PointAnimation Storyboard.TargetProperty="(UIElement.RenderTransformOrigin)" Storyboard.TargetName="UserControl" To="0,0"/>
</Storyboard>
