PageReport 怎样指定图片名称，导出图片？并且获取导出来的图片信息

登录

demo 代码：
  private PrintPreviewResponse PreviewPrint(PrintRequest print, GrapeCity.ActiveReports.PageReport rpt)
      {
         PrintPreviewResponse previewPrint = new PrintPreviewResponse();
         // Create an output directory.
         System.IO.DirectoryInfo outputDirectory = new System.IO.DirectoryInfo($"{AppDomain.CurrentDomain.BaseDirectory}PrintPreview");
         outputDirectory.Create();

         // Provide settings for your rendering output.
         GrapeCity.ActiveReports.Export.Image.Page.Settings imageSetting = new GrapeCity.ActiveReports.Export.Image.Page.Settings();
         GrapeCity.ActiveReports.Extensibility.Rendering.ISettings setting = imageSetting;//可以设置图片格式

         // Set the rendering extension and render the report.
         GrapeCity.ActiveReports.Export.Image.Page.ImageRenderingExtension imageRenderingExtension = new GrapeCity.ActiveReports.Export.Image.Page.ImageRenderingExtension();
         GrapeCity.ActiveReports.Rendering.IO.FileStreamProvider outputProvider = new GrapeCity.ActiveReports.Rendering.IO.FileStreamProvider(outputDirectory, System.IO.Path.GetFileNameWithoutExtension(outputDirectory.Name));

         // Overwrite output file if it already exists.
         outputProvider.OverwriteOutputFile = true;

         rpt.Document.Render(imageRenderingExtension, outputProvider, imageSetting);

         return previewPrint;
      }

rpt.Document.Render 执行后，outputProvider 有相关信息。如下图。但是多业务场景下，期望导出来的图片名称。是个性化的，不是每次都是【文件夹名称+001.bpm】这样格式的。
期望效果。指定图片名称。生成图片。

你好，你的意思是你想导出图片的时候，给图片名称进行一个命名是这样吗？
如果是这样，我这边没写过使用imag类型的，但是我导出Excel做过这样的设置，你可以参考下

protected void Button1_Click(object sender, EventArgs e)
{
GrapeCity.ActiveReports.PageReport rpt = new GrapeCity.ActiveReports.PageReport(new System.IO.FileInfo(Server.MapPath(@"Reports\RDL报表.rdlx")));
GrapeCity.ActiveReports.Document.PageDocument reportDocument = new GrapeCity.ActiveReports.Document.PageDocument(rpt);
// Provide settings for your rendering output.
GrapeCity.ActiveReports.Export.Excel.Page.ExcelRenderingExtensionSettings excelSetting = new GrapeCity.ActiveReports.Export.Excel.Page.ExcelRenderingExtensionSettings();
excelSetting.FileFormat = GrapeCity.ActiveReports.Export.Excel.Page.FileFormat.Xlsx;
GrapeCity.ActiveReports.Extensibility.Rendering.ISettings setting = excelSetting;
// Set the rendering extension and render the report.
GrapeCity.ActiveReports.Export.Excel.Page.ExcelRenderingExtension excelRenderingExtension = new GrapeCity.ActiveReports.Export.Excel.Page.ExcelRenderingExtension();
GrapeCity.ActiveReports.Rendering.IO.MemoryStreamProvider outputProvider = new GrapeCity.ActiveReports.Rendering.IO.MemoryStreamProvider();
reportDocument.Render(excelRenderingExtension, outputProvider, setting.GetSettings());
Response.ContentType = "application/vnd.ms-excel";
Response.AddHeader("content-disposition", "inline;filename=MyExport.xls");
System.IO.MemoryStream ms = new System.IO.MemoryStream();
//outputProvider.GetPrimaryStream().OpenStream().CopyTo(ms);
Response.BinaryWrite(ms.ToArray());
Response.End();
}

我已经解决了。
   var tiff = new GrapeCity.ActiveReports.Export.Image.Tiff.Section.TiffExport();
         var memStream = new System.IO.MemoryStream();
         tiff.Export(rpt.Document, memStream);
用的这玩意。。。虽然提示方法已过时
