Parameter Name: IsLandscape

Date Type: Boolean

Values supported: True, False (default)

Example:

 <Render>

<Extension Name="APPDF" Type=" Aspose.Pdf.ReportingServices.Renderer,Aspose.Pdf.ReportingServices ">

<Configuration>

        < IsLandscape >True</ IsLandscape >

</Configuration>

</Extension>

</Render>
