ABSTRACT:
A kerning method for adjusting a position of an object character relative to an immediately preceding character acting as a reference character, in arranging at least two characters in a predetermined arranging direction based on character frames, i.e. imaginary bodies, including character patterns or faces therein. The method comprises the steps of designating a desired space as a designated facing space between the faces, adding, as part of the faces, correction lines extending in a direction perpendicular to the arranging direction to the respective imaginary bodies of the reference character and the object character, computing a minimum facing space between the reference character and the object character to which the correction lines have been added, computing a space reduction amount for the added object character with respect to the added reference character to bring the minimum facing space into agreement with the designated facing space, and moving the object character toward the reference character by the space reduction amount computed.
