XtraReport.ExportToImage(Stream, ImageExportOptions) Method

Exports a report to the specified stream as an image. Use options to specify an image format.

Namespace: DevExpress.XtraReports.UI

Assembly: DevExpress.XtraReports.v20.2.dll

NuGet Packages: DevExpress.Reporting.Core, DevExpress.WindowsDesktop.Reporting.Core

Declaration

C#

public void ExportToImage(
    Stream stream,
    ImageExportOptions options = null
)

VB.NET

Public Sub ExportToImage(
    stream As Stream,
    options As ImageExportOptions = Nothing
)

Parameters

Name	Type	Description
stream	Stream	A Stream for output data.

Optional Parameters

Name	Type	Default	Description
options	ImageExportOptions	null	The Image export options. You can omit this parameter to use the current report export options.

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 file in Image format with the specified Image export options.

If you do not specify export options, the method uses the current report export options. To access the report export options, use the XtraReport.ExportOptions.Image notation.

Note

Do not set the ImageExportOptions.ExportMode property to ImageExportMode.DifferentFiles when you use this method to export to a stream.

Use the ExportToImageAsync(Stream, ImageExportOptions, CancellationToken) method instead of ExportToImage to export a report asynchronously in a separate task.

Example

This example demonstrates how to export a report to image format.

The project uses the XtraReport.ExportToImage method with the ImageExportOptions object as a parameter.

Note

The complete sample project How to export a report to Image format is available in the DevExpress Examples repository.
