jezweb/traitement-image

Qu'est-ce que traitement-image ?

Cette compétence est conçue pour les développeurs web qui doivent manipuler des images directement depuis leur agent IA (comme Claude Code, Cursor, etc.). Elle permet d'effectuer des opérations courantes : redimensionnement, recadrage, suppression des espaces blancs, conversion entre PNG, WebP et JPG, optimisation de la taille des fichiers, génération de miniatures et création d'images Open Graph (OG). La compétence repose sur la bibliothèque Python Pillow, évitant ainsi la dépendance à ImageMagick. Elle s'active facilement grâce à des déclencheurs en langage naturel comme « redimensionner une image », « convertir en webp », « rogner le logo », « optimiser les images », « créer une miniature », « créer une image OG », « rogner les espaces blancs », « traiter l'image » ou « image trop grande », rendant l'interaction intuitive et rapide pour les workflows de développement.
