Description

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

          (r1,c1) <= (r2,c2) := r1 < r2 or r1 = r2 and c1 <= c2

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

Attention

Only one region may be passed.

Result

The operator get_region_pointsget_region_pointsGetRegionPointsget_region_pointsGetRegionPointsGetRegionPoints normally returns the value 2 (H_MSG_TRUE). If more than one connection component is passed an exception is raised. The behavior in case of empty input (no input regions available) is set via the operator set_system('no_object_result',<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>).
