Commenti

Ogni due punti consecutivi nella matrice specificano un lato del poligono.Every two consecutive points in the array specify a side of the polygon. Inoltre, se l'ultimo punto e il primo punto non coincidono, specificano il lato di chiusura del poligono.In addition, if the last point and the first point do not coincide, they specify the closing side of the polygon.
