SmartArt

本文示範如何使用 Aspose.Slides for Node.js via Java 新增 SmartArt 圖形、存取它們、刪除它們，以及變更版面配置。

新增 SmartArt

使用內建版面配置之一插入 SmartArt 圖形。

function addSmartArt() {
    let presentation = new aspose.slides.Presentation();
    try {
        let slide = presentation.getSlides().get_Item(0);

        let smartArt = slide.getShapes().addSmartArt(50, 50, 400, 300, aspose.slides.SmartArtLayoutType.BasicProcess);

        presentation.save("smartart.pptx", aspose.slides.SaveFormat.Pptx);
    } finally {
        presentation.dispose();
    }
}

存取 SmartArt

取得投影片上的第一個 SmartArt 物件。

function accessSmartArt() {
    let presentation = new aspose.slides.Presentation("smartart.pptx");
    try {
        let slide = presentation.getSlides().get_Item(0);

        let firstSmartArt = null;
        for (let i = 0; i < slide.getShapes().size(); i++) {
            let shape = slide.getShapes().get_Item(i);
            if (java.instanceOf(shape, "com.aspose.slides.ISmartArt")) {
                firstSmartArt = shape;
                break;
            }
        }
    } finally {
        presentation.dispose();
    }
}

移除 SmartArt

從投影片中刪除 SmartArt 形狀。

function removeSmartArt() {
    let presentation = new aspose.slides.Presentation("smartart.pptx");
    try {
        let slide = presentation.getSlides().get_Item(0);

        // 假設第一個形狀是 SmartArt.
        let smartArt = slide.getShapes().get_Item(0);

        slide.getShapes().remove(smartArt);

        presentation.save("smartart_removed.pptx", aspose.slides.SaveFormat.Pptx);
    } finally {
        presentation.dispose();
    }
}

變更 SmartArt 版面配置

更新現有 SmartArt 圖形的版面配置類型。

function changeSmartArtLayout() {
    let presentation = new aspose.slides.Presentation("smartart.pptx");
    try {
        let slide = presentation.getSlides().get_Item(0);

        // 假設第一個形狀是 SmartArt.
        let smartArt = slide.getShapes().get_Item(0);

        smartArt.setLayout(aspose.slides.SmartArtLayoutType.VerticalPictureList);

        presentation.save("smartart_layout_changed.pptx", aspose.slides.SaveFormat.Pptx);
    } finally {
        presentation.dispose();
    }
}
