Beschreibung

distance_sldistance_slDistanceSlDistanceSlDistanceSl berechnet den minimalen und den maximalen orthogonalen Abstand zwischen einer Strecke und einer Geraden. Als Eingabe werden die Koordinaten der Strecke (RowA1RowA1RowA1RowA1rowA1,ColumnA1ColumnA1ColumnA1ColumnA1columnA1,RowA2RowA2RowA2RowA2rowA2,ColumnA2ColumnA2ColumnA2ColumnA2columnA2) und der Geraden (RowB1RowB1RowB1RowB1rowB1,ColumnB1ColumnB1ColumnB1ColumnB1columnB1,RowB2RowB2RowB2RowB2rowB2,ColumnB2ColumnB2ColumnB2ColumnB2columnB2) erwartet. Das Ergebnis, d.h. minimaler und maximaler Abstand, wird dann im Parameter DistanceMinDistanceMinDistanceMinDistanceMindistanceMin und DistanceMaxDistanceMaxDistanceMaxDistanceMaxdistanceMax übergeben. Falls sich die beiden Strecken schneiden, dann ist DistanceMinDistanceMinDistanceMinDistanceMindistanceMin gleich Null.
