在Word转成的XML指定书签中插入图像

在Word转成的XML指定书签中插入图像
在XML中图像的格式如下
其中图像以 ToBase64String 编码存在

            <w:r>
              <w:pict>
                <v:shapetype id="_x0000_t75" >
                </v:shapetype>
                <w:binData w:name="wordml://03000001.png">ToBase64String</w:binData>
                <v:shape id="_x0000_i1025" type="#_x0000_t75" style="width:138pt;height:28.5pt">
                 <v:imagedata src="wordml://03000001.png" /> 
                </v:shape>
              </w:pict>
            </w:r>

我做成了一个dll，可以直接调用
