Definition of GDI

By David Bolton, About.com

Definition: GDI is short for Graphical device Interface and is the part of the Win 32 and .NET that controls output to the computer screen and printers.

Through a rich API, the programmer can change fonts, pens, colours and draw lines and other shapes, including graphical images.

The GDI is not the same as the DirectX or XNA APIs which are used for writing games and fast screen updates.
