    摘要: An application programming interface is provided by an operating system that includes a direct composition engine. The composition engine maintains a data structure that represents the display objects to be rendered on a desktop display. The application programming interface allows an application to write data to the data structure to update the display object, such as a window, for the application. Thus, multiple applications can update their respective display objects in this data structure. The direct composition engine is an operating system level process, presented to user-level processes as a service of the operating system. By having an operating system level process, performance standards can be maintained. The application programming interface also allows applications to provide display information that can be rendered more efficiently by the operating system than by the application.

    摘要翻译: 应用编程接口由包括直接组合引擎的操作系统提供。 组合引擎维护表示在桌面显示器上呈现的显示对象的数据结构。 应用程序编程接口允许应用程序将数据写入数据结构,以更新应用程序的显示对象(如窗口)。 因此,多个应用可以在该数据结构中更新它们各自的显示对象。 直接组合引擎是操作系统级进程,作为操作系统的服务呈现给用户级进程。 通过操作系统级流程,可以保持性能标准。 应用程序编程接口还允许应用程序提供可由操作系统比应用程序更高效地呈现的显示信息。
