Ceci est pour convertir n'importe quelle image en format octet. Vous pouvez convertir le format jpg ou png au format octet et l’enregistrer éventuellement dans une base de données en utilisant Java. Ce script donne également des propriétés d'image telles que la largeur et la hauteur réelles de l'image en pixels. Yuu peut obtenir des propriétés d'image avec le format «largeur x hauteur» sous forme de chaîne.

Convertir une image en octet, obtenir la largeur et la hauteur d'une image à l'aide de Java
