Remarques

La XpsFont classe n’a pas de constructeur public.

Utilisez la AddFont méthode pour ajouter une police et obtenir une référence à celle-ci dans un nouveau document.

Utilisez la GetFont méthode pour obtenir une référence de police dans un document existant.

En fonction des paramètres etXpsSerializationManagerXpsPackagingPolicy, par FontSubsetterCommitPoliciesPackageInterleavingOrder exemple, l’opération de vidage de la méthode de la CommitXpsFont classe peut être retardée jusqu’à ce que l’ensemble XpsDocument soit fermé.
