Item An All-integer Algorithm for Drawing Anti-aliased Straight Lines(Blackwell Science Ltd and the Eurographics Association, 1994) Kui, Liu YongAn algorithm for drawing anti-aliased straight lines based on Bresenharn sline algorithm is presented in this paper. Only integer calculations are required. Multiplications or divisions are not needed (only simple addition/subtraction and sign testing are used). The algorithm can be used to choose between 2n intermediate grey levels between black and white.
