DWRITE_BREAK_CONDITION
alias DWRITE_BREAK_CONDITION = int

<summary> Condition at the edges of inline object or text used to determine line-breaking behavior. </summary>

DWRITE_FACTORY_TYPE
alias DWRITE_FACTORY_TYPE = int

<summary> Specifies the type of DirectWrite factory object. DirectWrite factory contains internal state such as font loader registration and cached font data. In most cases it is recommended to use the shared factory object, because it allows multiple components that use DirectWrite to share internal DirectWrite state and reduce memory usage. However, there are cases when it is desirable to reduce the impact of a component, such as a plug-in from an untrusted source, on the rest of the process by sandboxing and isolating it from the rest of the process components. In such cases, it is recommended to use an isolated factory for the sandboxed component. </summary>

IDWriteFontCollectionLoader
interface IDWriteFontCollectionLoader

<summary> The font collection loader interface is used to construct a collection of fonts given a particular type of key. The font collection loader interface is recommended to be implemented by a singleton object. IMPORTANT: font collection loader implementations must not register themselves with a 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. </summary>

IDWriteFontFileLoader

<summary> Font file loader interface handles loading font file resources of a particular type from a key. The font file loader interface is recommended to be implemented by a singleton object. IMPORTANT: 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. </summary>
