Methode Beschreibung
CreateEnumeratorFromKey

Creates a font file enumerator object that encapsulates a collection of font files. The font system calls back to this interface to create a font collection.

 

Hinweise

The font collection loader interface is recommended to be implemented by a singleton object. Note that font collection loader implementations must not register themselves with DirectWrite factory inside their constructors and must not unregister themselves in their destructors, because registration and unregistraton operations increment and decrement the object reference count respectively. Instead, registration and unregistration of font file loaders with DirectWrite factory should be performed outside of the font file loader implementation as a separate step.
