<Canvas x:Name="LayoutRoot" Width="500" Height="380">
  <Canvas.Background>
            <ImageBrush ImageSource="/Lighthouse.jpg"></ImageBrush>
        </Canvas.Background>
 <Canvas.Projection>
            <PlaneProjection x:Name="Grids" RotationX="-45"/>
        </Canvas.Projection>
 <Rectangle Canvas.Top = "30" > </Rectangle>
</Canvas>

如何让Rectangle 不受Canvas 的翻转控制呢，现在的效果是Rectangle 会和Canvas 一起翻转

谢谢大家
