本文演示如何使用 **Aspose.Slides for Node.js via Java** 添加 SmartArt 图形、访问它们、删除它们以及更改布局。

## **添加 SmartArt**

使用内置布局之一插入 SmartArt 图形。

```js
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();
    }
}
```

## **访问 SmartArt**

检索幻灯片上的第一个 SmartArt 对象。

```js
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();
    }
}
```

## **删除 SmartArt**

从幻灯片中删除 SmartArt 形状。

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

        // 假设第一个形状是 SmartArt.
        let smartArt = slide.getShapes().get_Item(0);

        slide.getShapes().remove(smartArt);

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

## **更改 SmartArt 布局**

更新现有 SmartArt 图形的布局类型。

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

        // 假设第一个形状是 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();
    }
}
```
