ABSTRACT:
A video graphics system and method for creating variable width lines such that the lines may be easily edited. As a line image is created, a center point of that image along its length is temporarily established having width information at various points. This width information is used to create an outline of image of the desired shape, the outline having point data spaced at intervals. This point data can then be edited by a user to create different shapes. In situations where a pressure sensitive stylus is used to create the variable length line, a look-back technique is employed to insure that the line remains wide at the end point even though the user is reducing pressure as the system is removed from the pad.
