itextSharp 对pdf的每个页面添加footer/header

   static void SetAllHeaderFooter(string inputPath)
         {

             PdfReader reader=new PdfReader(inputPath);
             PdfStamper stamp=new PdfStamper(reader , new FileStream(Guid.NewGuid().ToString("N")+".pdf" , FileMode.Create));

             for(int i= ; i<=reader.NumberOfPages ; i++)
             {
                 AddHeaderFooter(stamp , i , reader.NumberOfPages);
             }           

             stamp.Close();
             reader.Close();

         }

   static void AddHeaderFooter(PdfStamper stamp,int pageNum,int pageCount)
         {

              PdfContentByte cb =stamp.GetOverContent(pageNum); 

              Color green=new Color( ,  , );
              BaseFont bf = BaseFont.CreateFont(BaseFont.HELVETICA , BaseFont.CP1252 , BaseFont.NOT_EMBEDDED); 

              var header=new Rectangle( ,  ,  , );
              header.BackgroundColor=green;
              header.BorderColor=green;
              cb.Rectangle(header);
              cb.Stroke();

              var footer=new Rectangle( ,  ,  , );

              footer.BorderColor=green;
              cb.Rectangle(footer);
              cb.Stroke();

              cb.SetRGBColorFill( ,  , );

              cb.BeginText();
              cb.SetFontAndSize(bf , );

              cb.EndText();

              String pageText =string.Format("Page {0} of  {1}",pageNum,pageCount);
              float pageLen = bf.GetWidthPoint(pageText , );
              cb.BeginText();
              cb.SetFontAndSize(bf , );
              cb.SetTextMatrix( , );
              cb.ShowText(pageText);
              cb.EndText();
              cb.ResetRGBColorFill();

         }

最终结果是长这样的：
