描述
create_drawing_object_xldcreate_drawing_object_xldCreateDrawingObjectXldCreateDrawingObjectXldCreateDrawingObjectXldcreate_drawing_object_xld 创建一个 XLD 轮廓，用户可在 HALCON 窗口中对其进行交互式修改。该轮廓由其各点的坐标 RowRowRowRowrowrow 和 ColumnColumnColumnColumncolumncolumn 定义。
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编辑轮廓。在窗口中左键单击可添加新点。单击两个连续点之间的轮廓线段时，将在该区间插入新点。拖动各轮廓点的控制柄可移动该点。将单个轮廓点拖至与其直接相邻的相邻轮廓点上即可删除该点。将终点拖至起点可闭合轮廓。拖动中心控制柄可整体移动轮廓。此外，可通过
set_drawing_object_xldset_drawing_object_xldSetDrawingObjectXldSetDrawingObjectXldSetDrawingObjectXldset_drawing_object_xld 将新轮廓赋予绘图对象。
与 draw_xlddraw_xldDrawXldDrawXldDrawXlddraw_xld 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。
参数
RowRowRowRowrowrow (输入控制) coordinates.y-array → HTupleSequence[Union[float, int]]HTupleHtuple (real / integer) (double / int / long) (double / Hlong) (double / Hlong)
多边形的行坐标。
默认值：
[100,200,200,100]
建议值：
0, 10, 20, 50, 100, 200, 500
ColumnColumnColumnColumncolumncolumn (输入控制) coordinates.x-array → HTupleSequence[Union[float, int]]HTupleHtuple (real / integer) (double / int / long) (double / Hlong) (double / Hlong)
多边形的列坐标。
默认值：
[100,100,200,200]
建议值：
0, 10, 20, 50, 100, 200, 500
DrawIDDrawIDDrawIDDrawIDdrawIDdraw_id (输出控制) drawing_object → HDrawingObject, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)
绘图对象的句柄。
结果
如果参数值正确，算子 create_drawing_object_xldcreate_drawing_object_xldCreateDrawingObjectXldCreateDrawingObjectXldCreateDrawingObjectXldcreate_drawing_object_xld 返回值 2 (H_MSG_TRUE)。否则将抛出异常。
