get_region_pointsT_get_region_pointsGetRegionPointsGetRegionPointsget_region_points — Access the pixels of a region.

参数签名

描述

The operator 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.

运行信息

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

参数表

结果

The operator 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. 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>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>).
