The GDI is a layer between the application and the graphics hardware. It ensures device-independence and frees the programmer from having to deal with hardware details of individual devices. The device context, mentioned previously, is one of the fundamental mechanisms used by the GDI to implement device-independent graphics. The GDI is a two-dimensional interface, which contains no 3D graphics primitives or transformations. It is also a static system, with very little support for animation. Therefore, the GDI is not capable of doing everything that a graphics programmer may desire, but within these limitations, it provides an easy and convenient toolkit of fundamental functions.

The software program monitors the mouse movement and modifies the position and shape of the cursor accordingly. In response to the movement of the mouse, no complicated calculations are made. We combine the prepared patterns and display them by using the regular Windows API, namely, the GDI functions BitBlt() and AlphaBlend(). Rendering is not involved in this procedure; therefore, the delay time is essentially small.
