Description

The operator distance_sldistance_slDistanceSlDistanceSlDistanceSldistance_sl calculates the minimum and maximum orthogonal distance between a line segment and a line. As input the coordinates of two points on the line segment (RowA1RowA1RowA1RowA1rowA1row_a1,ColumnA1ColumnA1ColumnA1ColumnA1columnA1column_a1,RowA2RowA2RowA2RowA2rowA2row_a2,ColumnA2ColumnA2ColumnA2ColumnA2columnA2column_a2) and on the line (RowB1RowB1RowB1RowB1rowB1row_b1,ColumnB1ColumnB1ColumnB1ColumnB1columnB1column_b1,RowB2RowB2RowB2RowB2rowB2row_b2,ColumnB2ColumnB2ColumnB2ColumnB2columnB2column_b2) are expected. The parameters DistanceMinDistanceMinDistanceMinDistanceMindistanceMindistance_min and DistanceMaxDistanceMaxDistanceMaxDistanceMaxdistanceMaxdistance_max return the result of the calculation. If the line segments are intersecting, DistanceMinDistanceMinDistanceMinDistanceMindistanceMindistance_min returns zero.
