Questo metodo disegna una spline Cardinal chiusa che passa attraverso ogni punto della matrice.This method draws a closed cardinal spline that passes through each point in the array. Se l'ultimo punto non corrisponde al primo punto, viene aggiunto un segmento di curva aggiuntivo dall'ultimo punto al primo punto per chiuderlo.If the last point does not match the first point, an additional curve segment is added from the last point to the first point to close it.

La matrice di punti deve contenere almeno quattro Point strutture.The array of points must contain at least four Point structures.

Il tension parametro determina la forma della spline.The tension parameter determines the shape of the spline. Se il valore del tension parametro è 0,0 f, questo metodo disegna segmenti di linea retta per la connessione dei punti.If the value of the tension parameter is 0.0F, this method draws straight line segments to connect the points. In genere, tension il parametro è minore o uguale a 1,0 f.Usually, the tension parameter is less than or equal to 1.0F. I valori superiori a 1,0 F producono risultati insoliti.Values over 1.0F produce unusual results.

Questo metodo disegna una spline Cardinal chiusa che passa attraverso ogni punto della matrice.This method draws a closed cardinal spline that passes through each point in the array. Se l'ultimo punto non corrisponde al primo punto, viene aggiunto un segmento di curva aggiuntivo dall'ultimo punto al primo punto per chiuderlo.If the last point does not match the first point, an additional curve segment is added from the last point to the first point to close it.

La matrice di punti deve contenere almeno quattro PointF strutture.The array of points must contain at least four PointF structures.

Questo metodo usa una tensione predefinita di 0,5.This method uses a default tension of 0.5.
