描述
create_drawing_object_rectangle1create_drawing_object_rectangle1CreateDrawingObjectRectangle1CreateDrawingObjectRectangle1CreateDrawingObjectRectangle1create_drawing_object_rectangle1 创建一个沿坐标轴对齐的矩形，用户可在 HALCON 窗口中对其进行交互式修改。该矩形由其左上角和右下角的坐标 Row1Row1Row1Row1row1row_1、Column1Column1Column1Column1column1column_1、
Row2Row2Row2Row2row2row_2 和 Column2Column2Column2Column2column2column_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，用户可通过窗口交互编辑矩形。矩形对象支持两种变换操作：调整大小与位移。拖动矩形中部可移动对象，拖动角部控制柄可调整尺寸。
与 draw_rectangle1draw_rectangle1DrawRectangle1DrawRectangle1DrawRectangle1draw_rectangle1 算子不同，此交互操作不会阻塞调用线程。
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。
