按鈕邊框實現旋轉動畫

我有一個應用了背景畫筆的按鈕（25x25）。如果我旋轉按鈕，WPF將按鈕看作方形而不是圓形。我如何獲得按鈕邊界框的內容或按鈕的背景？按鈕邊框實現旋轉動畫

下面是後臺刷

而且這裏的標記是我的按鈕標記

<ToggleButton Name="btnToggleTaskBar" 
          Style="{StaticResource MetroArrow1RightStyle}" 
          FocusVisualStyle="{x:Null}" 
          VerticalAlignment="Top"> 
</ToggleButton> 

<Style x:Key="MetroArrow1RightStyle" 
      TargetType="{x:Type Control}"> 
     <Setter Property="Background" 
       Value="{DynamicResource MetroArrowBrush}" /> 
     <Setter Property="BorderBrush" 
       Value="{x:Null}" /> 
     <Setter Property="Foreground" 
       Value="{x:Null}" /> 
     <Setter Property="BorderThickness" 
       Value="0" /> 

    </Style>

我不知道是什麼問題，但如果您有動畫RenderTransform代替LayoutTransform？

是的我正在使用LayoutTransform而不是RenderTransform。所有的差異。謝謝！ – Matt 2012-03-28 16:27:43
