Shape Animations Made Easy with Aspose.Slides

Introduction

In the world of dynamic presentations, adding animations to shapes can significantly enhance the visual appeal and engagement of your slides. Aspose.Slides for .NET provides a powerful toolkit to achieve this seamlessly. In this tutorial, we’ll guide you through the process of applying animations to shapes using Aspose.Slides, allowing you to create captivating presentations that leave a lasting impression.

Prerequisites

Before we dive into the tutorial, make sure you have the following in place:

1. Aspose.Slides for .NET: Ensure you have the library installed and ready to use. You can download it here.
2. Development Environment: Set up your preferred development environment with the necessary configurations.
3. Document Directory: Create a directory to store your presentation files.

Import Namespaces

In your .NET application, start by importing the required namespaces:

using System.IO;
using Aspose.Slides;
using Aspose.Slides.Export;
using Aspose.Slides.Animation;
using System.Drawing;

Step 1: Create a Presentation

Begin by creating a new presentation using the Presentation class:

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

Step 2: Add Animated Shape

Now, let’s add an animated shape to the first slide of your presentation:

ISlide sld = pres.Slides[0];
IAutoShape ashp = sld.Shapes.AddAutoShape(ShapeType.Rectangle, 150, 150, 250, 25);
ashp.AddTextFrame("Animated TextBox");

Step 3: Apply Animation Effect

Add the ‘PathFootball’ animation effect to the created shape:

pres.Slides[0].Timeline.MainSequence.AddEffect(ashp, EffectType.PathFootball, EffectSubtype.None, EffectTriggerType.AfterPrevious);

Step 4: Create Trigger Button

Create a button that will trigger the animation:

IShape shapeTrigger = pres.Slides[0].Shapes.AddAutoShape(ShapeType.Bevel, 10, 10, 20, 20);

Step 5: Define Custom User Path

Define a custom user path for the animation:

ISequence seqInter = pres.Slides[0].Timeline.InteractiveSequences.Add(shapeTrigger);
IEffect fxUserPath = seqInter.AddEffect(ashp, EffectType.PathUser, EffectSubtype.None, EffectTriggerType.OnClick);
IMotionEffect motionBhv = ((IMotionEffect)fxUserPath.Behaviors[0]);
PointF[] pts = new PointF[1];
pts[0] = new PointF(0.076f, 0.59f);
motionBhv.Path.Add(MotionCommandPathType.LineTo, pts, MotionPathPointsType.Auto, true);
pts[0] = new PointF(-0.076f, -0.59f);
motionBhv.Path.Add(MotionCommandPathType.LineTo, pts, MotionPathPointsType.Auto, false);
motionBhv.Path.Add(MotionCommandPathType.End, null, MotionPathPointsType.Auto, false);
// Save the presentation as PPTX to disk
pres.Save(dataDir + "AnimExample_out.pptx", SaveFormat.Pptx);

This completes the step-by-step guide for applying animations to shapes using Aspose.Slides for .NET.
