For example, if you are using a graphics application and want to duplicate a part of an illustration, you will probably select the required area with your mouse and use a copy/paste function. To display your modified illustration, the graphics controller will locate the pixel data representing the area to be copied (in the video memory) and duplicate it in another part of the video memory.

Many operations performed by your graphics controller involve the
manipulation of pixel data stored in the video memory. For example, if
you are using a graphics application and want to duplicate a part of an
illustration, you will probably select the required area with your mouse
and use a copy/paste function. To display your modified illustration, the
graphics controller will locate the pixel data representing the area to be
copied (in the video memory) and duplicate it in another part of the
video memory.
To speed up the manipulation of pixel data, the graphics controller on
your Millennium Video Adapter provides a number of graphic
acceleration features. These features allow the graphics controller to
map areas of video memory to other areas of video memory using
simple algorithms. If you copy, rotate, stretch or transform a graphic
item on your display, you will be making use of these features.
