IDWriteFontCollectionLoader interface (dwrite.h)

  • Article

Used to construct a collection of fonts given a particular type of key.

Inheritance

The IDWriteFontCollectionLoader interface inherits from the IUnknown interface. IDWriteFontCollectionLoader also has these types of members:

Methods

The IDWriteFontCollectionLoader interface has these methods.

 
IDWriteFontCollectionLoader::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.

Remarks

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 unregistration 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.
