Des pointeurs pour les graphes et images de graphes

by Roland Levillain

Je viens de boucler la migration des dernières classes concernant les graphes et images de graphes ce soir. J'ai mis à jour la page du Trac qui référence les fichiers concernés : https://trac.lrde.org/olena/wiki/Olena/GraphBasedImages Ça peut t'être utile pour retrouver l'information nécessaire à ton travail. La plupart des tests passent, sauf ceux qui utilisent la morpho élémentaire (à cause du nouveau dispatcher dynamique de l'érosion et de la dilatation, mais c'est un autre sujet). Ne pas hésiter à me solliciter en cas de doute. Je vais continuer mon travail sur les complexes, en suivant/poursuivant un chemin parallèle au tient vis-à-vis des graphes : tu peux y jeter un oeil pour t'en inspirer. Bon courage !
