Animation

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

Add an Animation

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

static void AddAnimation()
{
    auto presentation = MakeObject<Presentation>();
    auto slide = presentation->get_Slide(0);

    auto shape = slide->get_Shapes()->AddAutoShape(ShapeType::Rectangle, 50, 50, 100, 100);

    // Fade effect.
    slide->get_Timeline()->get_MainSequence()->AddEffect(
        shape, EffectType::Fade, EffectSubtype::None, EffectTriggerType::OnClick);

    presentation->Dispose();
}

Access an Animation

Retrieve the first animation effect from the slide timeline.

static void AccessAnimation()
{
    auto presentation = MakeObject<Presentation>();
    auto slide = presentation->get_Slide(0);

    auto shape = slide->get_Shapes()->AddAutoShape(ShapeType::Rectangle, 50, 50, 100, 100);

    slide->get_Timeline()->get_MainSequence()->AddEffect(
        shape, EffectType::Fade, EffectSubtype::None, EffectTriggerType::OnClick);

    // Access the first animation effect.
    auto effect = slide->get_Timeline()->get_MainSequenceEffect(0);

    presentation->Dispose();
}

Remove an Animation

Remove an animation effect from the sequence.

static void RemoveAnimation()
{
    auto presentation = MakeObject<Presentation>();
    auto slide = presentation->get_Slide(0);

    auto shape = slide->get_Shapes()->AddAutoShape(ShapeType::Rectangle, 50, 50, 100, 100);

    auto effect = slide->get_Timeline()->get_MainSequence()->AddEffect(
        shape, EffectType::Fade, EffectSubtype::None, EffectTriggerType::OnClick);

    // Remove the effect.
    slide->get_Timeline()->get_MainSequence()->Remove(effect);

    presentation->Dispose();
}

Sequence Animations

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

static void SequenceAnimations()
{
    auto presentation = MakeObject<Presentation>();
    auto slide = presentation->get_Slide(0);

    auto shape1 = slide->get_Shapes()->AddAutoShape(ShapeType::Rectangle, 50, 50, 100, 100);
    auto shape2 = slide->get_Shapes()->AddAutoShape(ShapeType::Ellipse, 200, 50, 100, 100);

    auto sequence = slide->get_Timeline()->get_MainSequence();
    sequence->AddEffect(shape1, EffectType::Fly, EffectSubtype::Bottom, EffectTriggerType::OnClick);
    sequence->AddEffect(shape2, EffectType::Fly, EffectSubtype::Bottom, EffectTriggerType::OnClick);

    presentation->Dispose();
}
