Features: Generally, the term "multimedia" refers to the use of media other than text to convey information, such as animation, images, audio, or video. If programmers are required to develop multimedia features and incorporate them into applications, it would be very time-consuming and inefficient. However, if multimedia features are integrated into the operating system, it can significantly improve the development efficiency of multimedia applications. Windows itself provides extensive support for multimedia applications, such as GDI+ and MCI. GDI+ is part of Windows XP or Windows .NET Server operating systems, designed to provide two-dimensional vector graphics, image, and printing technologies. GDI+ is an improved version of GDI (Graphics Device Interface), which was included in early versions of Windows. It not only optimizes the existing performance of GDI but also adds many new features. MCI (Media Control Interface, media control interface) provides standard commands for playing multimedia devices and recording multimedia resource files. These commands serve as a universal interface for almost all types of multimedia devices. Other multimedia technologies, such as MCIWnd, audio/video manager, and video capture, are mostly based on MCI at their core. Microsoft DirectX is a low-level application programming interface (API, Application Programming Interface) used to create games or other high-performance multimedia applications. DirectX supports two-dimensional and three-dimensional graphics, sound effects, music, input devices, and network applications (e.g., multiplayer games). The latest version of DirectX is currently 8.1. DirectX is an excellent tool for creating PC games and multimedia applications. Most C/C++ DirectX application development uses common programming techniques; however, certain aspects of DirectX programming may involve specialized techniques. When developing multimedia applications on the Windows platform, you can either use built-in Windows multimedia technologies or Microsoft's advanced multimedia technology, DirectX. The former is primarily used to add media support to conventional applications, while the latter is mainly used for game development. Windows also supports other multimedia development technologies, such as OpenGL, but due to space constraints, this book will primarily focus on the technologies provided by Microsoft.
