投影片轉場

示範如何使用 Aspose.Slides for PHP via Java 套用投影片轉場效果與時間設定。

新增投影片轉場

將淡入轉場效果套用至第一張投影片。

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

        // 套用淡入轉場.
        $slide->getSlideShowTransition()->setType(TransitionType::Fade);

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

取得投影片轉場

讀取指派給投影片的轉場類型。

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

        // 取得轉場類型.
        $type = $slide->getSlideShowTransition()->getType();
    } finally {
        $presentation->dispose();
    }
}

移除投影片轉場

將類型設為 None 以清除所有轉場效果。

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

        // 移除轉場，將類型設為無.
        $slide->getSlideShowTransition()->setType(TransitionType::None);

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

設定轉場持續時間

指定投影片在自動前進前顯示的持續時間。

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

        $slide->getSlideShowTransition()->setAdvanceOnClick(true);
        $slide->getSlideShowTransition()->setAdvanceAfterTime(2000); // 以毫秒為單位.

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