使用 **Aspose.Slides for Node.js via Java** 创建形状组、访问、取消分组和删除的示例。

## **添加组形状**

创建一个包含两个基本形状的组。

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

        let group = slide.getShapes().addGroupShape();
        group.getShapes().addAutoShape(aspose.slides.ShapeType.Rectangle, 0, 0, 50, 50);
        group.getShapes().addAutoShape(aspose.slides.ShapeType.Ellipse, 60, 0, 50, 50);

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

## **访问组形状**

从幻灯片中检索第一个组形状。

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

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

## **删除组形状**

从幻灯片中删除组形状。

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

        // 假设第一个形状是组形状。
        slide.getShapes().removeAt(0);

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

## **取消分组形状**

将形状从组容器中移出。

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

        // 假设第一个形状是组形状。
        let group = slide.getShapes().get_Item(0);

        for (let i = 0; i < group.getShapes().size(); i++) {
            let shape = group.getShapes().get_Item(i);
            // 从组中克隆每个形状到幻灯片。
            slide.getShapes().addClone(shape);
        }

        slide.getShapes().remove(group);

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