群組圖形

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。

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。

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。

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。

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();
}
