# 群組圖形

> 在 Aspose.Slides for C++ 中管理群組圖形：建立、巢狀、對齊、重新排序及樣式化群組圖形，並提供 PPT、PPTX 與 ODP 簡報的 C++ 範例。

使用 **Aspose.Slides for C++** 建立圖形群組、存取、取消群組及移除的範例。

## **新增群組圖形**

建立一個包含兩個基本圖形的群組。

```cpp
static void AddGroupShape()
{
    auto presentation = MakeObject<Presentation>();
    auto slide = presentation->get_Slide(0);

    auto group = slide->get_Shapes()->AddGroupShape();
    group->get_Shapes()->AddAutoShape(ShapeType::Rectangle, 0, 0, 50, 50);
    group->get_Shapes()->AddAutoShape(ShapeType::Ellipse, 60, 0, 50, 50);

    presentation->Dispose();
}
```

## **存取群組圖形**

從投影片中取得第一個群組圖形。

```cpp
static void AccessGroupShape()
{
    auto presentation = MakeObject<Presentation>();
    auto slide = presentation->get_Slide(0);

    auto group = slide->get_Shapes()->AddGroupShape();
    group->get_Shapes()->AddAutoShape(ShapeType::Rectangle, 0, 0, 50, 50);

    auto firstGroup = SharedPtr<IGroupShape>();
    for (auto&& shape : slide->get_Shapes())
    {
        if (ObjectExt::Is<IGroupShape>(shape))
        {
            firstGroup = ExplicitCast<IGroupShape>(shape);
            break;
        }
    }

    presentation->Dispose();
}
```

## **移除群組圖形**

從投影片中刪除群組圖形。

```cpp
static void RemoveGroupShape()
{
    auto presentation = MakeObject<Presentation>();
    auto slide = presentation->get_Slide(0);

    auto group = slide->get_Shapes()->AddGroupShape();

    slide->get_Shapes()->Remove(group);

    presentation->Dispose();
}
```

## **取消圖形群組**

將圖形從群組容器中移出。

```cpp
static void UngroupShapes()
{
    auto presentation = MakeObject<Presentation>();
    auto slide = presentation->get_Slide(0);

    auto group = slide->get_Shapes()->AddGroupShape();
    auto rect = group->get_Shapes()->AddAutoShape(ShapeType::Rectangle, 0, 0, 50, 50);

    // 將圖形移出群組。
    slide->get_Shapes()->AddClone(rect);
    group->get_Shapes()->Remove(rect);

    presentation->Dispose();
}
```
