ABSTRACT:
A method of controlling the intercharacter spacing between adjacent characters in automatic typography systems. The method ensures that the autohinter creates even spacing between two adjacent characters as the resolution and font size varies. The left and right sidebearings of each character are hinted to one of a plurality of numbers of pixels to produce a hinted left sidebearing and a hinted right sidebearing. Next, a predetermined number of pixels are subtracted from one of the hinted sidebearings and added to the other of the hinted sidebearings. At font sizes less than a predetermined threshold, the plurality of numbers of pixels are such that the left and right sidebearings are hinted to a nearest integer plus one-half pixel, and at all font sizes greater than the predetermined threshold, the left and right sidebearings are hinted to a nearest integer.
