IDWriteFontFileLoader interface (dwrite.h)

Handles loading font file resources of a particular type from a font file reference key into a font file stream object.

Inheritance

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

Methods

The IDWriteFontFileLoader interface has these methods.

Remarks

The font file loader interface is recommended to be implemented by a singleton object. Note that font file 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.
