描述
create_drawing_object_rectangle2create_drawing_object_rectangle2CreateDrawingObjectRectangle2CreateDrawingObjectRectangle2CreateDrawingObjectRectangle2create_drawing_object_rectangle2 创建一个定向矩形（旋转矩形），用户可在 HALCON 窗口中对其进行交互式修改。该矩形由其中心坐标 RowRowRowRowrowrow 和 ColumnColumnColumnColumncolumncolumn、方向角 PhiPhiPhiPhiphiphi 以及两半轴长度
Length1Length1Length1Length1length1length_1 和 Length2Length2Length2Length2length2length_2 定义。创建的矩形通过句柄 DrawIDDrawIDDrawIDDrawIDdrawIDdraw_id 返回。
这些参数可随时通过 get_drawing_object_paramsget_drawing_object_paramsGetDrawingObjectParamsGetDrawingObjectParamsGetDrawingObjectParamsget_drawing_object_params 进行查询，其对应的 HALCON 对象也可通过 get_drawing_object_iconicget_drawing_object_iconicGetDrawingObjectIconicGetDrawingObjectIconicGetDrawingObjectIconicget_drawing_object_iconic 获取。
除上述参数外，每个绘图对象还包含若干决定其在 HALCON 窗口中外观的参数。具体参数数量及含义详见 set_drawing_object_paramsset_drawing_object_paramsSetDrawingObjectParamsSetDrawingObjectParamsSetDrawingObjectParamsset_drawing_object_params 说明。
为启用绘图对象的交互式修改功能，该对象必须附加到现有窗口。有关详细信息，请参阅 attach_drawing_object_to_windowattach_drawing_object_to_windowAttachDrawingObjectToWindowAttachDrawingObjectToWindowAttachDrawingObjectToWindowattach_drawing_object_to_window。附加后，用户可通过与窗口交互来编辑矩形。矩形 2 对象支持三种变换操作：尺寸调整、位移和旋转。拖动中心点可移动矩形，拖动边框控制柄可调整尺寸，仅当拖动与第一半轴垂直的边框时才能改变矩形方向。
与 draw_rectangle2draw_rectangle2DrawRectangle2DrawRectangle2DrawRectangle2draw_rectangle2 算子不同，此交互过程不会阻塞调用线程。
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
此算子返回一个句柄。请注意，即使该句柄被用作特定算子的输入参数，这些算子仍可能改变此句柄类型的实例状态。
