I am new to the com tools, and like what I see, but I am a bit surprised that a derivative class like PresentationEx does not share an Interface with Presentation class. The same with Slide and SlideEx and so on. Are there any plans to provide a common Interface for these objects?
Thanks for your interest in Aspose.Slides.
Unfortunately, currently there is no such interface between PresentationEx and Presentation is available. However, the feature will be expectedly available in after summer release.
We are sorry for your inconvenience.
Any news regarding the issue above?
