static void HOperatorSet.DistancePr(HObject region, HTuple row, HTuple column, out HTuple distanceMin, out HTuple distanceMax)

void HRegion.DistancePr(HTuple row, HTuple column, out HTuple distanceMin, out HTuple distanceMax)

void HRegion.DistancePr(double row, double column, out double distanceMin, out double distanceMax)

Description

The operator distance_prdistance_prDistancePrDistancePrDistancePr calculates the distance between a point and one region. As input the coordinates of the points (RowRowRowRowrow,ColumnColumnColumnColumncolumn) and one region are expected. If a point is inside of the region, its minimum distance is zero. The parameters DistanceMinDistanceMinDistanceMinDistanceMindistanceMin and DistanceMaxDistanceMaxDistanceMaxDistanceMaxdistanceMax return the result of the calculation.
