IDWriteInMemoryFontFileLoader interface (dwrite_3.h)

Represents a font file loader that can access in-memory fonts. The IDWriteFactory5::CreateInMemoryFontFileLoader method returns an instance of this interface, which the client can use to load in-memory fonts without having to implement a custom loader. A client can also create its own custom implementation, however. In either case, the client is responsible for registering and unregistering the loader using IDWriteFactory::RegisterFontFileLoader and IDWriteFactory::UnregisterFontFileLoader.
