Unit III: Graphics Algorithm – Computer Graphics and Multimedia Technology

The Line drawing algorithm is a graphical algorithm which is used to represent the line segment on discrete graphical media, i.e., printer and pixel-based media. A line contains two points. The point is an important element of a line.
