Bonjour,

Je me permets de poster une demande ici , car je suis en train de travailler sur un projet qui me demande de faire des captures d'image. J'ai visité un bon nombre de site et parcouru des forums dont celui-ci, mais je ne trouves pas de solution à ma problématique (cela est dû je pense à mon inexpérience en Java (2 mois de pratique en java ...).

Voici la totalité du script que j'ai suivi grâce à un tutoriel vidéo (sur la vidéo cela fonctionne bien, mais moi non...).

J'ai essayé diverses solutions, mais rien n'y fait :-(

Le but est de faire un .jar que des professionnels automobiles utiliseront pour faire des captures de véhicules via leurs tablettes.

Cordialement.
