Notes

Les objets Transform comporte un opérateur * (multiplication) personnalisé. resultat = tA * tB est équivalent à result = tA:clone():apply(tB). Il agit sur l'opération de multiplication de matrices qu’exécute Transform:apply.

L'opérateur * créé un nouvel objet Transform, il n'est donc pas recommandé de l'utilisé en trop grande quantité sur du code image par image.
