WPF Geometry 添加Path数据

当图片转svg，svg转Xaml后，根据数据加载显示图片

DrawingImage：

     <DrawingImage x:Key="Image.Search">

         <DrawingImage.Drawing>

             <GeometryDrawing>

                 <GeometryDrawing.Brush>

                     <SolidColorBrush Color="#FF666666" Opacity="0.5" />

                 </GeometryDrawing.Brush>

                 <GeometryDrawing.Geometry>

                     <PathGeometry FillRule="Nonzero"

             </GeometryDrawing>

         </DrawingImage.Drawing>

也有可能，同时也需要Geometry：

     <StreamGeometry x:Key="Path.Stream.Search">

     </StreamGeometry>

如何将俩种引用方式，提取Path数据重用？

StreamGeometry不行，没有相应的属性可以支持。。。。

所以我们换个Geomery，虽然没有StreamGeometry性能好。。。

同时，使用PathFigureCollection装载Path数据，然后PathGeometry、DrawingImage 引用资源。

     <PathFigureCollection x:Key="PathData">M6.5,2C4.01471853256226,2 2,4.01471853256226 1.99999988079071,6.5 2,8.98528099060059 4.01471853256226,11 6.5,11 8.98528099060059,11 11,8.98528099060059 11,6.5 11,4.01471853256226 8.98528099060059,2 6.5,2z M6.5,1.00000011920929C9.53756618499756,1 12,3.46243381500244 12,6.5 12,7.65749835968018 11.6424360275269,8.73148345947266 11.03173828125,9.61752414703369L13.9562683105469,12.5420551300049C14.3431911468506,12.9289779663086 14.3429946899414,13.5565004348755 13.9497470855713,13.9497470855713 13.5592231750488,14.3402719497681 12.923752784729,14.3379669189453 12.5420551300049,13.9562683105469L9.61752414703369,11.03173828125C8.73148345947266,11.6424360275269 7.65749835968018,12 6.5,12 3.46243381500244,12 1,9.53756618499756 0.999999940395355,6.5 1,3.46243381500244 3.46243381500244,1 6.5,1.00000011920929z</PathFigureCollection>

     <PathGeometry x:Key="Path.Search" Figures="{StaticResource PathData}"/>

     <DrawingImage x:Key="Image.Search">
