描述

算子 get_region_pointsget_region_pointsGetRegionPointsGetRegionPointsGetRegionPointsget_region_points returns the region data in the form of coordinate lists. The coordinates are sorted in the following order:

get_region_pointsget_region_pointsGetRegionPointsGetRegionPointsGetRegionPointsget_region_points returns the coordinates in the form of tuples. An empty region is passed as empty tuple.

注意

Only one region may be passed.

This region is accessed.

RowsRowsRowsRowsrowsrows (输出控制)  coordinates.y-array HTupleSequence[int]HTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Line numbers of the pixels in the region

Column numbers of the pixels in the region.

元素数量: Columns == Rows

结果

算子 get_region_pointsget_region_pointsGetRegionPointsGetRegionPointsGetRegionPointsget_region_points normally returns the value 2 ( H_MSG_TRUE )。 If more than one connection component is passed an exception is raised. 当输入为空(无可用输入区域)时,可设置行为通过算子 set_system('no_object_result',<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>)
