Description
The operator distance_srdistance_srDistanceSrDistanceSrDistanceSr calculates the distance between
a line segment and one region.
Row1Row1Row1Row1row1, Column1Column1Column1Column1column1, Row2Row2Row2Row2row2, Column2Column2Column2Column2column2
are the start and end coordinates of a line segment.
The parameters DistanceMinDistanceMinDistanceMinDistanceMindistanceMin and DistanceMaxDistanceMaxDistanceMaxDistanceMaxdistanceMax
contain the resulting distances.
Attention
To enhance distance_srdistance_srDistanceSrDistanceSrDistanceSr,
holes are ignored.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
