Définit la classe SoLeResource qui contient des informations sur un calque d’objet intelligent dans un fichier PSD. Est utilisé pour prendre en charge les calques d’objet intelligent avec des liens de fichiers externes dans les images Adobe® Photoshop®.
Le code suivant illustre la prise en charge des ressources SoLEResource, SmartObjectResource et PlacedResource.
