动画

展示如何使用 Aspose.Slides for PHP via Java 创建简单动画并管理其顺序。

添加动画

创建一个矩形形状，并应用在点击时触发的淡入效果。

function addAnimation() {
    $presentation = new Presentation();
    try {
        $slide = $presentation->getSlides()->get_Item(0);
        $shape = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 50, 50, 100, 100);

        // 淡入效果。
        $slide->getTimeline()->getMainSequence()->addEffect($shape, EffectType::Fade, EffectSubtype::None, EffectTriggerType::OnClick);

        $presentation->save("animation.pptx", SaveFormat::Pptx);
    } finally {
        $presentation->dispose();
    }
}

访问动画

从幻灯片时间轴中检索第一个动画效果。

function accessAnimation() {
    $presentation = new Presentation("animation.pptx");
    try {
        $slide = $presentation->getSlides()->get_Item(0);

        // 访问第一个动画效果。
        $effect = $slide->getTimeline()->getMainSequence()->get_Item(0);
    } finally {
        $presentation->dispose();
    }
}

移除动画

从序列中移除动画效果。

function removeAnimation() {
    $presentation = new Presentation("animation.pptx");
    try {
        $slide = $presentation->getSlides()->get_Item(0);
        $effect = $slide->getTimeline()->getMainSequence()->get_Item(0);

        // 删除效果。
        $slide->getTimeline()->getMainSequence()->remove($effect);

        $presentation->save("animation_removed.pptx", SaveFormat::Pptx);
    } finally {
        $presentation->dispose();
    }
}

动画顺序

添加多个效果并演示动画发生的顺序。

function sequenceAnimations() {
    $presentation = new Presentation();
    try {
        $slide = $presentation->getSlides()->get_Item(0);

        $shape1 = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 50, 50, 100, 100);
        $shape2 = $slide->getShapes()->addAutoShape(ShapeType::Ellipse, 200, 50, 100, 100);

        $sequence = $slide->getTimeline()->getMainSequence();
        $sequence->addEffect($shape1, EffectType::Fly, EffectSubtype::Bottom, EffectTriggerType::OnClick);
        $sequence->addEffect($shape2, EffectType::Fly, EffectSubtype::Bottom, EffectTriggerType::OnClick);

        $presentation->save("animation_sequence.pptx", SaveFormat::Pptx);
    } finally {
        $presentation->dispose();
    }
}
