Description
The operator distance_lrdistance_lrDistanceLrDistanceLrDistanceLrdistance_lr calculates the orthogonal
distance between a line and one region.
As input the coordinates of two points on a line
(Row1Row1Row1Row1row1row_1,Column1Column1Column1Column1column1column_1,
Row2Row2Row2Row2row2row_2,Column2Column2Column2Column2column2column_2) and one region are expected.
The parameters DistanceMinDistanceMinDistanceMinDistanceMindistanceMindistance_min and DistanceMaxDistanceMaxDistanceMaxDistanceMaxdistanceMaxdistance_max
return the result of the calculation.
Attention
Due to efficiency of distance_lrdistance_lrDistanceLrDistanceLrDistanceLrdistance_lr
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.
