I fail to find PDF encryption/print permission etc. options for PDF conversion on Aspose Slides. Aspose.Slides.Export.PdfOptions class seems fairly limited comparing to the other products(Words, Stylesheet, Diagram) which already have this feature.
I prefer not to use Aspose.Pdf for this as it pretty much doubles the job and I can't use the overloaded Save method with HttpResponse; thus performance will fall significantly.
So, does this functionality exist in an other class/method that I couldn't find? Otherwise when is it expected for Aspose.Slides to support this functionality?
