用C#实现Word,PPT,EXECL 图片输出

1. 因为要做一个在线阅读模块，所以研究了一天，终于找到了一个比较好的方案：
   
2. 
   
3. 1.准备两个工具，office 运行库(interop),虚拟打印机Tagged Images Printer (就是MSOFFICE中Document Imaging的组件)
   
4. 
   
5. 2.原理就是用虚拟打印机打印到文件，再把tiff格式转成普通图像格式
   
6. 
   
7. 这里是实现:
   
8. 
   
9. 添加对应的引用
   
10. 
    
11. view plaincopy to clipboardprint?
    
12. using Word = Microsoft.Office.Interop.Word; 
    
13. using PPT = Microsoft.Office.Interop.PowerPoint; 
    
14. using EXECL = Microsoft.Office.Interop.Excel; 
    
15.  
    
16. 
    
17. 以下是doc转图像的method
    
18. 
    
19. view plaincopy to clipboardprint?
    
20. string imagepath = null; 
    
21. /// <summary>&#160;
    
22. /// doc 转 图像&#160;
    
23. /// </summary>&#160;
    
24. /// <param name="filepath">要转换的文档的路径(要加文件名)e.g. : C:\users\jackyyf\desktop\abc.doc</param>&#160;
    
25. /// <param name="temppath">临时文件的路径（不要加文件名）e.g. : C:\users\jackyyf\desktop\</param>&#160;
    
26. /// <param name="outputpath">输出的文档的路径（要加文件名）e.g. : C:\users\jackyyf\desktop\abc.jpg</param>&#160;
    
27. public void DOCtoIMAGE(string filepath,string temppath,string outputpath, System.Drawing.Imaging.ImageFormat imageformat)&#160;
    
28. {&#160;
    
29. &#160;&#160;&#160; object FileName = (object)filepath;&#160;
    
30. &#160;&#160;&#160; object ReadOnly = (object)true;&#160;
    
31. &#160;&#160;&#160; object PrintToFile = (object)true;&#160;
    
32. &#160;&#160;&#160; object OutPutFiletemp = (object)temppath+DateTime.Now.Ticks.ToString()+".tiff";&#160;
    
33. &#160;&#160;&#160; Word.ApplicationClass appclass = new Word.ApplicationClass();&#160;
    
34. &#160;&#160;&#160; appclass.Documents.Open(ref FileName, ReadOnly: ref ReadOnly);&#160;
    
35. &#160;&#160;&#160; appclass.ActivePrinter = "Tagged Images Printer";&#160;
    
36. &#160;&#160;&#160; appclass.PrintOut(FileName: ref FileName,&#160;&#160;
    
37. &#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160; PrintToFile: ref PrintToFile,&#160;&#160;
    
38. &#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160; OutputFileName: ref OutPutFiletemp);&#160;
    
39. &#160;&#160;&#160; appclass.Documents.Close();&#160;
    
40. &#160;&#160;&#160; appclass.Quit();&#160;
    
41. &#160;&#160;&#160; System.Drawing.Image img = System.Drawing.Image.FromFile(OutPutFiletemp.ToString());&#160;
    
42. &#160;&#160;&#160; img.Save(outputpath, imageformat);&#160;
    
43. &#160;&#160;&#160; img.Dispose();&#160;
    
44. &#160;&#160;&#160; File.Delete(OutPutFiletemp.ToString());&#160;
    
45. }&#160;
    
46. &#160;
    
47. 
    
48. 这是ppt转图像的代码，还没做method.&#160;
    
49. 
    
50. 因为ppt可以直接保存 为图像，就简单一点了，呵呵
    
51. 
    
52. view plaincopy to clipboardprint?
    
53. PPT.ApplicationClass PPTappclass = new PPT.ApplicationClass();&#160;
    
54. PPT.Presentation PPTpre = PPTappclass.Presentations.Open(@"C:\Users\jackyyf\Desktop\haha.ppt", Office.MsoTriState.msoFalse, Office.MsoTriState.msoFalse, Office.MsoTriState.msoFalse);&#160;
    
55. PPTpre.SaveAs(@"C:\Users\jackyyf\Desktop\haha.jpg", PPT.PpSaveAsFileType.ppSaveAsJPG);&#160;
    
56. &#160;
    
57. 
    
58. 这是execl转图像的代码,没做method, 文件路径自己去改了..
    
59. 
    
60. view plaincopy to clipboardprint?
    
61. object ActivePrinter = (object)"Tagged Images Printer";&#160;
    
62. object PrintToFile = (object)true;&#160;
    
63. object PrToFileName = (object)@"C:\users\jackyyf\desktop" + DateTime.Now.Ticks.ToString();&#160;
    
64. EXECL.ApplicationClass EXECLappclass = new EXECL.ApplicationClass();&#160;
    
65. EXECL.Workbook EXECLwb = EXECLappclass.Workbooks.Open(@"C:\users\jackyyf\desktop\haha007.xls");&#160;
    
66. EXECLwb.PrintOutEx(ActivePrinter: ActivePrinter, PrintToFile: PrintToFile, PrToFileName: PrToFileName);&#160;
    
67. EXECLwb.Close();&#160;
    
68. EXECLappclass.Quit();&#160;
    
69. System.Drawing.Image img = System.Drawing.Image.FromFile(PrToFileName.ToString());&#160;
    
70. img.Save(@"c:\users\jackyyf\desktop\haha.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);&#160;
    
71. img.Dispose();&#160;
    
72. File.Delete(PrToFileName.ToString());&#160;
