In this tutorial, we’ll explore how to control slide animations using Aspose.Slides for .NET. Aspose.Slides is a powerful library that enables seamless manipulation of PowerPoint presentations in a .NET environment.

Prerequisites

Before diving into the tutorial, ensure you have the following in place:

Aspose.Slides for .NET Library: Download and install the library from the download page.
Document Directory: Create a directory to store your presentation files. Update the dataDir variable in the code snippet with the path to your document directory.

Import Namespaces

Make sure to import the necessary namespaces at the beginning of your .NET file:

using Aspose.Slides.Export;
using Aspose.Slides.SlideShow;

Now, let’s break down the provided example into multiple steps:

Step 1: Create Presentation Instance

Instantiate the Presentation class to represent your presentation file:

using (Presentation pres = new Presentation(dataDir + "BetterSlideTransitions.pptx"))
{
    // Code for slide animations goes here
}

Step 2: Apply Circle Type Transition

Apply a circle type transition to the first slide:

pres.Slides[0].SlideShowTransition.Type = TransitionType.Circle;

Set the transition time to 3 seconds:

pres.Slides[0].SlideShowTransition.AdvanceOnClick = true;
pres.Slides[0].SlideShowTransition.AdvanceAfterTime = 3000;

Step 3: Apply Comb Type Transition

Apply a comb type transition to the second slide:

pres.Slides[1].SlideShowTransition.Type = TransitionType.Comb;

Set the transition time to 5 seconds:

pres.Slides[1].SlideShowTransition.AdvanceOnClick = true;
pres.Slides[1].SlideShowTransition.AdvanceAfterTime = 5000;

Step 4: Apply Zoom Type Transition

Apply a zoom type transition to the third slide:

pres.Slides[2].SlideShowTransition.Type = TransitionType.Zoom;

Set the transition time to 7 seconds:

pres.Slides[2].SlideShowTransition.AdvanceOnClick = true;
pres.Slides[2].SlideShowTransition.AdvanceAfterTime = 7000;

Step 5: Save the Presentation

Write the modified presentation back to disk:

pres.Save(dataDir + "SampleTransition_out.pptx", SaveFormat.Pptx);

Now you have successfully controlled slide animations using Aspose.Slides for .NET!
