pdf/a for reporting service extension

Dear all,

I use Aspose.Pdf.ReportingServices version 1.6.0.0 to render pdf/a output.

The rsreportserver.config is configured normally without this additional pdf conformance.

In the programming code, I set up the device info for this Aspose pdf extension:

<DeviceInfo><PdfConformance>PdfA1B</PdfConformance></DeviceInfo>

But the rendered pdf file is not in pdf/a but in normal pdf format.

Could you please help me on this?

Many thanks.

Kind regards,

- Bui
