描述
The operator distance_prdistance_prDistancePrDistancePrDistancePrdistance_pr calculates the distance
between a point and one region.
As input the coordinates of the points
(RowRowRowRowrowrow,ColumnColumnColumnColumncolumncolumn) and one
region are expected.
If a point is inside of the region, its minimum distance is zero.
The parameters
DistanceMinDistanceMinDistanceMinDistanceMindistanceMindistance_min and DistanceMaxDistanceMaxDistanceMaxDistanceMaxdistanceMaxdistance_max return
the result of the calculation.
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.
