超链接

演示如何在形状上使用 Aspose.Slides for PHP via Java 添加、访问、删除和更新超链接。

添加超链接

创建一个矩形形状，并为其添加指向外部网站的超链接。

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

        $shape = $slide->getShapes()->addAutoShape(ShapeType::Rectangle, 50, 50, 150, 50);
        $shape->getTextFrame()->setText("Aspose");

        $paragraph = $shape->getTextFrame()->getParagraphs()->get_Item(0);
        $portion = $paragraph->getPortions()->get_Item(0);
        $portion->getPortionFormat()->setHyperlinkClick(new Hyperlink("https://www.aspose.com"));

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

访问超链接

从形状的文本部分读取超链接信息。

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

        // 假设第一个形状包含超链接。
        $shape = $slide->getShapes()->get_Item(0);

        $paragraph = $shape->getTextFrame()->getParagraphs()->get_Item(0);
        $portion = $paragraph->getPortions()->get_Item(0);
        $hyperlink = $portion->getPortionFormat()->getHyperlinkClick();
    } finally {
        $presentation->dispose();
    }
}

删除超链接

从形状的文本中清除超链接。

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

        // 假设第一个形状包含超链接。
        $shape = $slide->getShapes()->get_Item(0);

        $paragraph = $shape->getTextFrame()->getParagraphs()->get_Item(0);
        $portion = $paragraph->getPortions()->get_Item(0);
        $portion->getPortionFormat()->setHyperlinkClick(null);

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

更新超链接

更改现有超链接的目标。使用 HyperlinkManager 修改已包含超链接的文本，这模拟了 PowerPoint 安全更新超链接的方式。

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

        // 假设第一个形状包含超链接。
        $shape = $slide->getShapes()->get_Item(0);

        $paragraph = $shape->getTextFrame()->getParagraphs()->get_Item(0);
        $portion = $paragraph->getPortions()->get_Item(0);

        // 在已有文本中更改超链接应通过
        // HyperlinkManager 而不是直接设置属性来完成。
        // 这模仿了 PowerPoint 安全更新超链接的方式。
        $portion->getPortionFormat()->getHyperlinkManager()->setExternalHyperlinkClick("https://new.example.com");

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