Pour obtenir des informations sp\u00e9cifiques \u00e0 un fichier PDF, vous devez cr\u00e9er un objet de la classe PdfFileInfo<\/a>. Apr\u00e8s cela, vous pouvez obtenir les valeurs des propri\u00e9t\u00e9s individuelles telles que Sujet, Titre, Mots-cl\u00e9s et Cr\u00e9ateur, etc.<\/p>\n

Le fragment de code suivant vous montre comment obtenir des informations sur un fichier PDF.<\/p>\n

La classe PdfFileInfo<\/a> vous permet de d\u00e9finir des informations sp\u00e9cifiques au fichier d’un document PDF. Vous devez cr\u00e9er un objet de la classe PdfFileInfo<\/a> puis d\u00e9finir diff\u00e9rentes propri\u00e9t\u00e9s sp\u00e9cifiques au fichier telles que l’Auteur, le Titre, les Mots-cl\u00e9s et le Cr\u00e9ateur, etc. Enfin, enregistrez le fichier PDF mis \u00e0 jour en utilisant la m\u00e9thode saveNewInfo(..)<\/a> de l’objet PdfFileInfo<\/a>.<\/p>\n
