在 AIR 生成PDF和显示

1. 下载 AlivePDF
   http://code.google.com/p/alivepdf/downloads/list

2. 解压 “AlivePDF 0.1.4.9.zip”, 把 "AlivePDF.swc" 复制到 project 的 /libs 目录内



3. 生成 PDF 并在浏览器显示

        fs.writeBytes(bytes);   
        fs.close(); 
		
	//在新开的浏览器窗口显示 pdf 
	navigateToURL(new URLRequest(File.desktopDirectory.nativePath +"/"+ uupdf));
      }

当然，你的电脑需要能正常显示PDF文件，即已安装 Adobe Reader 或 FOXIT READER.
