Method and apparatus for moving control points in displaying digital typeface on raster output devices

Abstract

Abstract A method for manipulating the control points of a symbol image for improving digital typeface on raster output device, comprising the steps of: storing in a first memory means control points specifying the outlines of a symbol image, said first memory including addresses of a plurality of desired movement direction and desired measurement direction specifying a desired movement direction in which said control points should move; specifying a desired measurement direction by which said control points should be measured, said desired measurement direction forming a predetermined angle with said desired movement direction; moving said control points in said desired movement direction by using values specified for said desired movement direction; measuring said control points against said predetermined angle with said desired movement direction, said measurement producing a resulting movement direction; storing the results of outline manipulation in a second memory means; whereby a family of improved digital typeface is formed.
