Windows GDI Purpose The Microsoft® Windows® graphics device interface (GDI) enables applications to use graphics and formatted text on both the video display and the printer. Windows-based applications do not access the graphics hardware directly. Instead, GDI interacts with device drivers on behalf of applications. Where Applicable GDI can be used in all Windows-based applications. Developer Audience This API is designed for use by C/C++ programmers. Familiarity with the Windows graphical user interface and message-driven architecture is required. Run-time Requirements For information on which operating systems are required to use a particular function, see the Requirements section of the documentation for the function.
