Cette fonction est actuellement non documentée ; seule la liste des arguments est disponible.
Dessine une courbe de Bézier quadratique, en coordonnées relatives, par
rapport au point courant (x
,y
),
en utilisant le point (x1
,y1
) comme
point de contrôle. A la fin du dessin, le nouveau point courant
devient le point final (x
,y
)
utilisé par le polybezier.
x1
abscisse du point de contrôle
y1
ordonnée du point de contrôle
x
abscisse du point final
y
ordonnée du point final
