En m'inspirant d'exemples existants , j'ai un script qui crée un
nouveau dossier, et à partir d'une sélection d'images dans Iphoto,
les copie dans ce dossier, auquel le script attache un "folder action
script" pratiquement identique à un script Apple de traitement
d'images, et qui produit une version comprimée et réduite des images.
Voir ci dessous.
Or cela ne fonctionne pas de façon fiable. J'ai très fréquemment une
erreur qui provient du "folder action script":
L'opération n'a pu être effectuée, car certains éléments ont été
ignorés. "Nom_image" -15266
Je n'arrive pas à comprendre quelle est cette erreur -15266 et
comment l'éviter. Je n'ai pas trouvé ce numéro d'erreur dans les
listes d'erreurs. Pour contourner le problème, faudrait il intégrer
les éléments et actions du "folder action script" dans mon script
principal? Je précise que certains des fichiers originaux sont très
volumineux, mais ceci ne semble pas lié à l'apparition de l'erreur...
Merci
