Name
distance_prdistance_prDistancePrDistancePrdistance_pr — Calculate the distance between a point and a region.
Signature
void DistancePr(const HObject& Region, const HTuple& Row, const HTuple& Column, HTuple* DistanceMin, HTuple* DistanceMax)
void HRegion::DistancePr(const HTuple& Row, const HTuple& Column, HTuple* DistanceMin, HTuple* DistanceMax) const
void HRegion::DistancePr(double Row, double Column, double* DistanceMin, double* DistanceMax) const
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)
def distance_pr(region: HObject, row: MaybeSequence[Union[float, int]], column: MaybeSequence[Union[float, int]]) -> Tuple[Sequence[float], Sequence[float]]
def distance_pr_s(region: HObject, row: MaybeSequence[Union[float, int]], column: MaybeSequence[Union[float, int]]) -> Tuple[float, float]
Description
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.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
