描述
The operator distance_srdistance_srDistanceSrDistanceSrDistanceSrdistance_sr calculates the distance between
a line segment and one region.
Row1Row1Row1Row1row1row_1, Column1Column1Column1Column1column1column_1, Row2Row2Row2Row2row2row_2, Column2Column2Column2Column2column2column_2
are the start and end coordinates of a line segment.
The parameters DistanceMinDistanceMinDistanceMinDistanceMindistanceMindistance_min and DistanceMaxDistanceMaxDistanceMaxDistanceMaxdistanceMaxdistance_max
contain the resulting distances.
注意
To enhance distance_srdistance_srDistanceSrDistanceSrDistanceSrdistance_sr,
holes are ignored.
