Prerequisites

Before we dive into the tutorial, ensure you have the following prerequisites in place:

1. Aspose.Slides for .NET Library: Download and install the library from here.
2. .NET Development Environment: Set up a .NET development environment on your machine.

Import Namespaces

In your .NET project, begin by importing the necessary namespaces to leverage the functionalities provided by Aspose.Slides:

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

Step 1: Set Up the Project

Create a new directory for your project and instantiate the Presentation class to represent the presentation file.

string dataDir = "Your Document Directory";
bool IsExists = System.IO.Directory.Exists(dataDir);
if (!IsExists)
    System.IO.Directory.CreateDirectory(dataDir);
using (Presentation pres = new Presentation(dataDir + "AnimationOnSlide.pptx"))
{
    // Your code goes here
}

Step 2: Access Effects Sequence

Retrieve the effects sequence for the first slide using the MainSequence property.

ISequence effectsSequence = pres.Slides[0].Timeline.MainSequence;

Step 3: Access the First Effect

Obtain the first effect of the main sequence to manipulate its properties.

IEffect effect = effectsSequence[0];

Step 4: Modify Repeat Settings

Change the effect’s Timing/Repeat property to “Until End of Slide.”

effect.Timing.RepeatUntilEndSlide = true;

Step 5: Save the Presentation

Save the modified presentation to visualize the changes.

pres.Save(RunExamples.OutPath + "AnimationOnSlide-out.pptx", Aspose.Slides.Export.SaveFormat.Pptx);

Repeat these steps for additional effects or customize them according to your presentation requirements.
