AE二次开发C#语言导出地图为JPG、TIF、PDF图片

我的开发环境为ArcGIS Engine 10.2与Visual studio2010。创建一个菜单或按钮，创建一个点击事件，粘贴代码即可实现。我的主地图名称为axMapControl1，如果变动则需要修改（注意相关事件的添加与动态链接库的引入）！，这个导出是当前地图窗口范围的导出，导出的范围取决于地图窗口的当前内容。SaveFileDialog 的FilterIndex 从1开始不是从0，这点容易出错！
实现代码：

private void 地图导出_Click(object sender, EventArgs e)
{
    ExportMapToImage();
}

private void ExportMapToImage()
{
    try
    {
        SaveFileDialog pSaveDialog = new SaveFileDialog();
        pSaveDialog.FileName = "";
        pSaveDialog.Filter = "JPG图片(*.JPG)|*.jpg|tif图片(*.tif)|*.tif|PDF文档(*.PDF)|*.pdf";
        if (pSaveDialog.ShowDialog() == DialogResult.OK)
        {
            double iScreenDispalyResolution = axMapControl1.ActiveView.ScreenDisplay.DisplayTransformation.Resolution;// 获取屏幕分辨率的值
            IExporter pExporter = null;
            if (pSaveDialog.FilterIndex == 1)
            {
                pExporter = new JpegExporter() as IExporter;
            }
            else if (pSaveDialog.FilterIndex == 2)
            {
                pExporter = new TiffExporter() as IExporter;
            }
            else if (pSaveDialog.FilterIndex == 3)
            {
                pExporter = new PDFExporter() as IExporter;
            }
            pExporter.ExportFileName = pSaveDialog.FileName;
            pExporter.Resolution = (short)iScreenDispalyResolution; //分辨率
            tagRECT deviceRect = axMapControl1.ActiveView.ScreenDisplay.DisplayTransformation.get_DeviceFrame();
            IEnvelope pDeviceEnvelope = new Envelope() as IEnvelope;
            pDeviceEnvelope.PutCoords(deviceRect.left, deviceRect.bottom, deviceRect.right, deviceRect.top);
            pExporter.PixelBounds = pDeviceEnvelope; // 输出图片的范围
            ITrackCancel pCancle = new CancelTracker();//可用ESC键取消操作
            axMapControl1.ActiveView.Output(pExporter.StartExporting(), pExporter.Resolution, ref deviceRect, axMapControl1.ActiveView.Extent, pCancle);
            Application.DoEvents();
            pExporter.FinishExporting();
        }
    }
    catch (Exception Err)
    {
        MessageBox.Show(Err.Message, "输出图片", MessageBoxButtons.OK, MessageBoxIcon.Information);
    }
}
