Viens rassembler les indices et bouts de code Python chaque jour de l'Avent ; sois parmi les premiers à passer l'une des portes pour gagner de superbes cadeaux de Noël !
Nouveauté par rapport à la version publique d'img2calc, ici la fonction draw_image() gère non seulement les facteurs de zoom entiers, mais également les facteurs négatifs pour les retournements.
