RegisterFontCollectionLoader Method

In This Topic

Registers a custom font collection loader with the factory object.

Syntax

Visual Basic
C#

'Declaration
 
Public Sub RegisterFontCollectionLoader( _
   ByVal fontCollectionLoader As FontCollectionLoader _
)

public void RegisterFontCollectionLoader( 
   FontCollectionLoader fontCollectionLoader
)

Parameters

fontCollectionLoader: Reference to a FontCollectionLoader object to be registered.

Return Value

If the method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

This function registers a font collection loader with DirectWrite. The font collection loader interface, which should be implemented by a singleton object, handles enumerating font files in a font collection given a particular type of key. A given instance can only be registered once. Succeeding attempts will return an error, indicating that it has already been registered. Note that font file loader implementations must not register themselves with DirectWrite inside their constructors, and must not unregister themselves inside their destructors, because registration and unregistraton operations increment and decrement the object reference count respectively. Instead, registration and unregistration with DirectWrite of font file loaders should be performed outside of the font file loader implementation.
