word里用javascrpit把InlineShapes图片转化成Shape图片,然后修改版式的问题

代码如下:   
          var   doc   =   new   ActiveXObject('Word.Application');     
          var   range       =       doc.Range;                           //选择的区域       
          var   sel   =     doc.Selection;                             //选择点   
          var   seal_picture   =   doc.InlineShape;         //嵌入型图片   
          var   str   ;                                                             //印章图片的路径和文件名     
          var   seal_shape   =doc.Shape;                           //粘贴版型图片   
          var   docurl="C:\\temp\\"+document.forms[0].NewsTitleQG.value+".doc";   
      //     doc.Visible   =   true;                                                 
          doc.Documents.Open   (docurl);   
      //     doc.Application.Activate();                             
                                                                        //获得书签位置   
          range       =     doc.ActiveDocument.Bookmarks("seal1").Range;     
          sel   =   range;   
          str       =       "D:\\印章\\南宁供电局合同印章2.bmp";   
                                                                                                              //插入图片   
          seal_picture     =     sel.InlineShapes.AddPicture(str);       
                                                                                                      //设置可用名   
          seal_picture.AlternativeText   =   "印章";   
          seal_picture.Select();                                                     //当前图片为焦点   
          seal_shape   =   seal_picture.ConvertToShape();           //类型转换   
          seal_shape.WrapFormat.Type   =   3;                                   //图片类型   
          seal_shape.ZOrder(5);                             //5   图片沉于文字　４　图片浮于文字   
          doc.ActiveDocument.SaveAs("C:\\temp\\bb.doc");                     
          doc=null;

var seal_picture=TANGER_OCX_OBJ.ActiveDocument.InlineShape;
 seal_picture=TANGER_OCX_OBJ.ActiveDocument.FormFields('CheckedBy').Range.InlineShapes.AddPicture('http://www.niyuewo.com\\aa\\aa.jpg');
 seal_picture.Select();                                                     //当前图片为焦点   
 seal_shape=seal_picture.ConvertToShape();           //类型转换   
 seal_shape.WrapFormat.Type   =   3;                                   //图片类型   
 seal_shape.ZOrder(5);                             //5   图片沉于文字　４　图片浮于文字
