<p>
Dessine une part de camembert (comme celles des histogrammes circulaires), le tout inclus dans un rectangle défini par <em>x</em>, <em>y</em>, <em>largeur</em>, et <em>hauteur</em>. Le centre du cercle ou de l’ellipse est le centre du rectangle. Les angles sont définis à partir de la position midi et dans le sens des aiguilles d'une montre en radian. l'arc est tracé depuis l'angle <em>angledepart</em> et l'arc fait un angle de <em>angleouverture</em>.
