Abstract

This article describes a method of kerning on character box, raster scan CRT displays. Kerning is the placing of characters on a line such that they overlap into the adjacent character box. Character arrangements such as this are frequently seen where the shapes of the characters interfit, for example, a capital "T" followed by a lower case "o" wherein the lower case "o" is, in effect, displaced a half character to the left so as to appear under a portion of the capital "T". Another example is seen when a capital "A" following a capital "V" is displaced partly to the left so as to interfit with the capital "V".
