Abstract

L'invention porte sur un système donné à titre d'exemple qui comprend un lecteur d'identifiant pour lire un identifiant progressif, une partie de modification d'espace blanc et un dispositif de commande. L'identifiant progressif comprend un espace blanc et un espace non blanc. Le dispositif de commande est destiné à sélectionner des parties de l'espace blanc à changer en un espace non blanc, et à amener la partie de modification d'espace blanc à changer les parties sélectionnées de l'espace blanc en un espace non blanc. La quantité d'espace blanc sélectionné pour être changée en espace non blanc est constante pour tous les stades de la progression.
