Abstract

La présente invention concerne un procédé et un dispositif de réalisation d'une déformation d'image basée sur glissement sur un terminal, un appareil électronique et un support de stockage lisible par ordinateur. Le procédé de réalisation d'une déformation d'image basée sur glissement sur un terminal comprend les étapes consistant à : déterminer un point de glissement sur une image à déformer affichée sur un écran de terminal (S1) ; effectuer un glissement pour déformer l'image selon une opération de déclenchement par rapport au point de glissement ; et afficher l'image déformée sur l'écran de terminal (S3). Le procédé résout le problème technique de l'état de la technique dans lequel une déformation d'image est très peu maniable, et ainsi un utilisateur est incapable de manipuler librement une image pour obtenir l'effet de déformation souhaité.
