23              cb.BeginText();
24              cb.SetFontAndSize(bf , 12);
25              cb.SetTextMatrix(70 , 800);
26         
27              cb.ShowText("U als ondernemer");
28              cb.SetTextMatrix(550-bf.GetWidthPoint("Resultaten" , 12) , 800);
29              cb.ShowText("Resultaten");
30              cb.EndText();
31             
32              String pageText =string.Format("Page {0} of  {1}",pageNum,pageCount);
33              float pageLen = bf.GetWidthPoint(pageText , 12);
34              cb.BeginText();
35              cb.SetFontAndSize(bf , 12);
36              cb.SetTextMatrix(280 , 40);
37              cb.ShowText(pageText);
38              cb.EndText();
39              cb.ResetRGBColorFill();

41          
42 
43         }

最终结果是长这样的：
