c#,ae,布局视图导出jpg图片很不清晰怎么办？
我的代码是：
private void toolStripComboBox2_Click(object sender, EventArgs e)
      {
            SaveFileDialog pSaveDialog = new SaveFileDialog();
            pSaveDialog.FileName = "";
            pSaveDialog.Filter = "JGP图片(*.jpg)|*.jpg|tif图片(*.tif)|*.tif|PDF文档(*.pdf)|*.pdf";
            if (pSaveDialog.ShowDialog() == DialogResult.OK)
            {
                  // 获取布局视图屏幕分辨率，用于设置输出分辨率
                  double iScreenDispalyResolution = axPageLayoutControl1.ActiveView.ScreenDisplay.DisplayTransformation.Resolution;
                  // 根据用户选择保存的文件类型，来创建不同的输出类
                  IExporter pExport=null ;
                  if (pSaveDialog.FilterIndex == 1)
                  {
                  pExport = new JpegExporter() as IExporter;
                  }
                  else if (pSaveDialog.FilterIndex == 2)
                  {
                     pExport = new TiffExporter() as IExporter;
                  }
                  else if (pSaveDialog.FilterIndex == 3)
                  {
                     pExport = new PDFExporter() as IExporter;
                  }
                  // 设置输出文件名，为用户在保存窗口设置的文件名
                  pExport.ExportFileName = pSaveDialog.FileName;
                  // 设置输出分辨率
                  pExport.Resolution = (short)iScreenDispalyResolution;
            // 获取输出范围？？  获取视图框架对象，进而得到视图范围
            IActiveView pActiveView = axPageLayoutControl1.PageLayout as IActiveView;
            IActiveView view = pActiveView.FocusMap as IActiveView;
            tagRECT deviceRect = view.ExportFrame;//.ScreenDisplay.DisplayTransformation.get_DeviceFrame();
            IEnvelope pDeviceEnvelop = new EnvelopeClass();
                  // 设置一个边框范围
                  pDeviceEnvelop.PutCoords(deviceRect.left, deviceRect.bottom, deviceRect.right, deviceRect.top);
            // 将打印像素范围设置给输出对象
            pExport.PixelBounds = pDeviceEnvelop;
                  // 设置跟踪取消对象
                  ITrackCancel pCancle = new CancelTracker();
                  // 进行视图控件的视图输出操作，设置对应参数
                  axPageLayoutControl1.ActiveView.Output(pExport.StartExporting(), pExport.Resolution, ref deviceRect, null,null);
                  Application.DoEvents();// 启动应用程序
                  pExport.FinishExporting();//完成输出
            }
      }
我将分辨率设置为600也还是不清晰，请问怎么解决？
