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.
Chain encoding, discrete equation, discrete straight line, grid intersect, quantized line drawing.
