Abstract :
A new method of description of a straight line defined on a square grid is presented. The discrete equation of the straight line (desl) is introduced as an extension of the classical Cartesian equation, and applies to straight lines quantized on a grid by the grid intersect method. The desl includes a set of intercepts which can be scanned in proper order to generate the chain for the given straight line.
