<grid>     <image name="image" source="c:\users\public\pictures\sample pictures\koala.jpg"/>     <path fill="#aaffffff">         <path.data>             <combinedgeometry geometrycombinemode="xor">                 <combinedgeometry.geometry1>                     <rectanglegeometry rect="0,0,10000,10000"/>                 </combinedgeometry.geometry1>                 <combinedgeometry.geometry2>                     <rectanglegeometry x:name="transparentrect" rect="150,100,200,100"/>                 </combinedgeometry.geometry2>             </combinedgeometry>         </path.data>     </path> </grid>
