Blend 4 vs Visual Studio 2010矢量渲染

Question

我有一个非常罕见的问题。我有一个带矢量的.AI文件。当我将一些矢量导入Expression Blend 4时，我看到矢量非常好，但是，当我将XAML代码复制到Visual Studio（COPY＆amp; PASTE）时，图像真的很糟糕。

图标代码：

<Canvas x:Key="FloatingWindowCloseIcon" Height="18.081" Width="18.077" x:Shared="false">
        <Canvas.CacheMode>
            <BitmapCache EnableClearType="True" RenderAtScale="2.0" />
        </Canvas.CacheMode>
        <Path Data="F1M20.9619,11.8481C15.9699,11.8481,11.9229,15.8951,11.9229,20.8881C11.9229,25.8791,15.9699,29.9291,20.9619,29.9291C25.9529,29.9291,29.9999,25.8791,29.9999,20.8881C29.9999,15.8951,25.9529,11.8481,20.9619,11.8481 M20.9619,13.2251C25.1869,13.2251,28.6229,16.6651,28.6229,20.8881C28.6229,25.1151,25.1869,28.5521,20.9619,28.5521C16.7359,28.5521,13.2999,25.1151,13.2999,20.8881C13.2999,16.6651,16.7359,13.2251,20.9619,13.2251" Fill="#FFF4F4F4" Height="18.081" Canvas.Left="0" Stretch="Fill" Canvas.Top="0" Width="18.077"/>

    </Canvas>
