Pictures and Animation

I have a set of pictures in my presentation. Can i control via aspose. the time of visibility of each image? I want to have some sort of movie - each pic is shown for 0.5 second and the the other and so on

Sure, you can control it with Aspose.Slides.

In most simple case if you have one image per slide then you can change advance time
for each slide through Slide.SlideShowTransition.AdvanceTime property.

Check SlideShowTransition interface and “Slide Transition” chapter in the Programmer’s Guide.
