Creating Read-only Powerpoint Presentations

Is it possible to create a read-only version of .ppt using Aspose.Slides (v.2.7.9.0)? I'm already creating a single custom presentation from individual slides, chosen by the user of my application. However, the client does not want the end user to modify the slides in any way.

Can I do the equivalent of setting a Password To Modify in the Powerpoint interface? or is my only option to save as a .pps file?

Hello,

There is a workaround of this problem which is to add master slides as many as normal slides where original contents will be on a master slide and normal slide will just display master contents.

An example of it can be found at this link.
