Beschreibung
distance_srdistance_srDistanceSrDistanceSrDistanceSr berechnet den Abstand zwischen einer Strecke
und einer Region.
Als Eingabe werden die Anfangs- und Endpunkte der jeweiligen Strecke
(Row1Row1Row1Row1row1,Column1Column1Column1Column1column1,Row2Row2Row2Row2row2,Column2Column2Column2Column2column2)
und eine Region erwartet. Das entsprechende Ergebnis wird in den Parametern
DistanceMinDistanceMinDistanceMinDistanceMindistanceMin und DistanceMaxDistanceMaxDistanceMaxDistanceMaxdistanceMax übergeben.
Achtung
Aus Laufzeitgründen werden in distance_srdistance_srDistanceSrDistanceSrDistanceSr
Löcher der Region nicht berücksichtigt.
Ausführungsinformationen
- Multithreading-Typ: reentrant (läuft parallel zu nicht-exklusiven Operatoren).
- Multithreading-Bereich: global (kann von jedem Thread aufgerufen werden).
- Wird ohne Parallelisierung verarbeitet.
