web页面实现flash播放pdf，word文档等（asp.net c#+flash Paper+SWFTools）

因最近一个工作项目的需要，也做了一个像百度文库那种在web页的flash中能播放pdf文档、word文档，其实原理比较简单。
只在上传时还是在启动播放时，把自动pdf转换为swf，然后调用flash Paper播放就可。
要用到的工具
1、 SWFTools  ，安装完成后通过WEB编程调用其实现对文档的转换。
2、 flash pager 一个swf播放插件，集成有缩小放大，拖动，全屏等功能，不一定要用这个， 也可以自己用AS写一个。

效果如下：

代码如下：
asp.net c#

view source

print?

01public string execStr = "";

02        public static bool PDF2SWF(string pdfPath, string swfPath, int page)

03        {

04            string exe = HttpContext.Current.Server.MapPath("~/Bin/pdf2swf.exe");

05            pdfPath = HttpContext.Current.Server.MapPath(pdfPath);

06            swfPath = HttpContext.Current.Server.MapPath(swfPath);

07            if (!System.IO.File.Exists(exe) || !System.IO.File.Exists(pdfPath) || System.IO.File.Exists(swfPath))

08            {

09                return false;

10            }

11            StringBuilder sb = new StringBuilder();

12            sb.Append(" /"" + pdfPath + "/"");//input

13            sb.Append(" -o /"" + swfPath + "/"");//output

14            //sb.Append(" -z");

15            sb.Append(" -s flashversion=9");//flash version

16            //sb.Append(" -s disablelinks");//禁止PDF里面的链接

17            sb.Append(" -p " + "/"1" + "-" + page + "/"");//page range

18            sb.Append(" -j 100");//SWF中的图片质量

19            string Command = sb.ToString();

20            System.Diagnostics.Process p = new System.Diagnostics.Process();

21  

22            p.StartInfo.FileName = exe;

23            p.StartInfo.Arguments = Command;

24            p.StartInfo.WorkingDirectory = HttpContext.Current.Server.MapPath("~/Bin/");

25            p.StartInfo.UseShellExecute = false;//不使用操作系统外壳程序 启动 线程

26            //p.StartInfo.RedirectStandardInput = true;

27            //p.StartInfo.RedirectStandardOutput = true;

28            p.StartInfo.RedirectStandardError = true;//把外部程序错误输出写到StandardError流中(这个一定要注意,pdf2swf.exe的所有输出信息,都为错误输出流,用 StandardOutput是捕获不到任何消息的...

29            p.StartInfo.CreateNoWindow = true;//不创建进程窗口

30            p.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;

31            p.Start();//启动线程

32            p.BeginErrorReadLine();//开始异步读取

33            p.WaitForExit();//等待完成

34            //p.StandardError.ReadToEnd();//开始同步读取

35            p.Close();//关闭进程

36            p.Dispose();//释放资源

37            return true;

38        }

39        public static bool PdfToSwf(string pdfPath, string swfPath)

40        {

41            return PDF2SWF(pdfPath, swfPath, GetPageCount(HttpContext.Current.Server.MapPath(pdfPath)));

42        }

43  

44        public static int GetPageCount(string pdfPath)

45        {

46            //try

47            //{

48            byte[] buffer = System.IO.File.ReadAllBytes(pdfPath);

49            int length = buffer.Length;

50            if (buffer == null)

51                return -1;

52            if (buffer.Length <= 0)

53                return -1;

54            string pdfText = Encoding.Default.GetString(buffer);

55            System.Text.RegularExpressions.Regex rx1 = new System.Text.RegularExpressions.Regex(@"/Type/s*/Page[^s]");

56            System.Text.RegularExpressions.MatchCollection matches = rx1.Matches(pdfText);

57            return matches.Count;

58            //}

59            //catch (Exception ex)

60            //{

61            //    throw ex;

62            //}

63        }

64    public string getSwfPath(string filePath){//返回一个以swf扩展名结尾的新路径

65        return "swf/" + filePath.Replace(System.IO.Path.GetExtension(filePath), "").Replace("shwpoppdf/","pdf") + ".swf";

66    }

67    protected void Page_Load(object sender, EventArgs e)

68    {

69        PdfToSwf("shwpoppdf/sitemap.pdf", getSwfPath("shwpoppdf/sitemap.pdf"));//调用函数做文件转换

70        execStr = "<script>sSwf(/"" + getSwfPath("shwpoppdf/sitemap.pdf") + "/")</script>";//调用前台Js flashpaper实现播放

71    }

页面代码：

view source

print?

01function sSwf(swf){

02         var swfVersionStr = "10.0.0";  

03         var xiSwfUrlStr = "playerProductInstall.swf";  

04         var flashvars = {  

05               SwfFile : escape(swf),  

06   Scale : 0.6,  

07   ZoomTransition : "easeOut",  

08   ZoomTime : 0.5,  

09     ZoomInterval : 0.1,  

10     FitPageOnLoad : false,  

11     FitWidthOnLoad : true,  

12     PrintEnabled : true,  

13     FullScreenAsMaxWindow : false,  

14     ProgressiveLoading : true,  

15     PrintToolsVisible : true,  

16     ViewModeToolsVisible : true,  

17     ZoomToolsVisible : true,  

18     FullScreenVisible : true,  

19     NavToolsVisible : true,  

20     CursorToolsVisible : true,  

21   SearchToolsVisible : true,  

22     localeChain: "zh_CN" 

23   };  

24  

25 var params = {  

26  

27    }  

28         params.quality = "high";  

29         params.bgcolor = "#ffffff";  

30         params.allowscriptaccess = "sameDomain";  

31         params.allowfullscreen = "true";  

32         var attributes = {};  

33         attributes.id = "FlexPaperViewer";  

34         attributes.name = "FlexPaperViewer";  

35         swfobject.embedSWF(  

36             "FlexPaperViewer.swf", "flashContent",  

37             "650", "500",  

38             swfVersionStr, xiSwfUrlStr,  

39             flashvars, params, attributes);  

40swfobject.createCSS("#flashContent", "display:block;text-align:left;");  

41}

调用：
<div id=”flashContent”>
      <%=execStr%> 
</div>
