Change version of PDF in PDF created using Aspose

Hi Team,

Currently when we create PDF using Aspose PDF v 9.2, the version of PDF we get is version 1.7. But when we create using v9.0 we get version of PDF as 1.4. We would like to set version of PDF generated as less than 1.5 no matter which version of Aspose PDF we use.

Thanks & Regards,
