Remarks
Note
Once the document export has started, it runs to completion and you cannot interrupt or cancel it.
This method exports a report to a Image file with the specified Image export options.
If the export options are not specified, the current report export options are used. To access the report export options, use the the report’s XtraReport.ExportOptions property. The property contains the ExportOptions object whose ExportOptions.Image property provides access to the ImageExportOptions object that contains the Image export options.
Use the ExportToImageAsync(Stream, ImageExportOptions, CancellationToken) method instead of ExportToImage to export a report asynchronously in a separate task.
