Windows GDI


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 message-driven architecture is required.
