描述
该算子 gen_rectangle1gen_rectangle1GenRectangle1GenRectangle1GenRectangle1gen_rectangle1 generates one or more rectangles parallel
to the coordinate axes which are described by the upper left corner
(Row1Row1Row1Row1row1row_1, Column1Column1Column1Column1column1column_1) and the lower right corner
(Row2Row2Row2Row2row2row_2, Column2Column2Column2Column2column2column_2).
More than one region can be created by passing a tuple of corner points.
The coordinate system runs from (0,0) (upper left corner) to
(Width-1,Height-1). See get_systemget_systemGetSystemGetSystemGetSystemget_system
and reset_obj_dbreset_obj_dbResetObjDbResetObjDbResetObjDbreset_obj_db in this context.
运行信息
- 多线程类型:可重入(与非独占操作符并行运行)。
- 多线程作用域:全局(可以从任何线程调用)。
- 未经并行化处理。

返回值 2 (
H_MSG_TRUE)
.
Otherwise an exception is raised.
The clipping according to the current image format is set via the
operator set_system('clip_region',<'true'/'false'>)set_system("clip_region",<"true"/"false">)SetSystem("clip_region",<"true"/"false">)SetSystem("clip_region",<"true"/"false">)SetSystem("clip_region",<"true"/"false">)set_system("clip_region",<"true"/"false">).
