Animation

This article demonstrates how to create simple animations and manage their sequence using Aspose.Slides for .NET.

Add an Animation

Create a rectangle shape and apply a fade effect triggered on click.

static void AddAnimation()
{
    using var presentation = new Presentation();
    var slide = presentation.Slides[0];

    var shape = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 50, 50, 100, 100);

    // Fade effect.
    slide.Timeline.MainSequence.AddEffect(shape, EffectType.Fade, EffectSubtype.None, EffectTriggerType.OnClick);
}

Access an Animation

Retrieve the first animation effect from the slide timeline.

static void AccessAnimation()
{
    using var presentation = new Presentation();
    var slide = presentation.Slides[0];

    var shape = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 50, 50, 100, 100);
    slide.Timeline.MainSequence.AddEffect(shape, EffectType.Fade, EffectSubtype.None, EffectTriggerType.OnClick);

    // Access the first animation effect.
    var effect = slide.Timeline.MainSequence[0];
}

Remove an Animation

Remove an animation effect from the sequence.

static void RemoveAnimation()
{
    using var presentation = new Presentation();
    var slide = presentation.Slides[0];

    var shape = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 50, 50, 100, 100);
    var effect = slide.Timeline.MainSequence.AddEffect(shape, EffectType.Fade, EffectSubtype.None, EffectTriggerType.OnClick);

    // Remove the effect.
    slide.Timeline.MainSequence.Remove(effect);
}

Sequence Animations

Add multiple effects and demonstrate the order in which animations occur.

static void SequenceAnimations()
{
    using var presentation = new Presentation();
    var slide = presentation.Slides[0];

    var shape1 = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 50, 50, 100, 100);
    var shape2 = slide.Shapes.AddAutoShape(ShapeType.Ellipse, 200, 50, 100, 100);

    var sequence = slide.Timeline.MainSequence;
    sequence.AddEffect(shape1, EffectType.Fly, EffectSubtype.Bottom, EffectTriggerType.OnClick);
    sequence.AddEffect(shape2, EffectType.Fly, EffectSubtype.Bottom, EffectTriggerType.OnClick);
}
