Hi,
When I use Aspose.Slides to convert a .pptx to .pdf, I want to add encryption settings (user password, owner password, permissions) to the .pdf file.
In Aspose.Cells to convert .xlsx to .pdf we can achieved this by
In Aspose.Word to convert .docx to .pdf we can also do this by
Password Protect PDF - Aspose.Words
However, according to Aspose.Slides API and instructions Convert PowerPoint to PDF in C#|Aspose.Slides Documentation, it only introduced how to set one password which is a single string value to the PdfOptions, and I couldn’t find a way to set permissions/user password/owner password for the converted .pdf file like what I did in Aspose.Cells and Aspose.Word.
Could you please tell me how to do this in Aspose.Slides?
Thanks,
