Configuring the Image Rendering Extension to generate TIFF files

HOW-TO
Configure the Image Rendering Extension to Generate TIFF Files

SOLUTION
By default the Image Rendering Extension generates TIFF files with LZW compression and resolution 96 x 96 dpi. In case you need bi-tonal (black and white) images, for example when you need to send the rendered report by fax, you may consider using any of the CCITT Group 3/Group 4 or RLE compressions which will produce files with smaller size.

In Telerik Reporting, device information settings are used to pass rendering parameters to a rendering extension.

You can specify device information settings in a variety of ways. You can use the <Telerik.Reporting> configuration section to specify rendering parameters globally. Programmatically, you can use the ReportProcessor.RenderReport() method. For more information about specifying rendering parameters globally, see Configuring Telerik Reporting.

The example below shows a sample application configuration file (App.config or Web.config depending on whether it is a Windows Forms or ASP.NET application) in which we modify the original Image rendering extension settings to generate high resolution (300 x 300 dpi) images and register four new formats that use the CCITT G3/G4, RLE and None compressions.


As a result, in the Report Viewer's drop-down with the available export formats, you will see all of the above registered TIFF extensions.
