動畫

本文示範如何使用 Aspose.Slides for C++ 建立簡單的動畫並管理其序列。

新增動畫

建立一個矩形形狀，並套用在點擊時觸發的淡入效果。

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);

    // 淡入效果。
    slide->get_Timeline()->get_MainSequence()->AddEffect(
        shape, EffectType::Fade, EffectSubtype::None, EffectTriggerType::OnClick);

    presentation->Dispose();
}

存取動畫

從投影片時間軸擷取第一個動畫效果。

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);

    // 取得第一個動畫效果。
    auto effect = slide->get_Timeline()->get_MainSequenceEffect(0);

    presentation->Dispose();
}

移除動畫

從序列中移除動畫效果。

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);

    // 移除效果。
    slide->get_Timeline()->get_MainSequence()->Remove(effect);

    presentation->Dispose();
}

動畫排序

新增多個效果，並示範動畫發生的順序。

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();
}
