Abstract
A simple method of anti-aliasing for edges near the fast scan direction is to replace the pixels on both sides of the transition in a scan with pixels of varying intermediate color. Thus, if there is an edge between red and blue areas, instead of there being an abrupt change from red to blue at the edge, there will be a number of pixels that slowly vary from mostly red to mostly blue, which will tend to make the jagged edge less obvious.
