Abstract
A method and apparatus for drawing high quality lines on color matrix displays wherein a line segment is created by activating a series of linear elements substantially centered about the predetermined line segment position and providing for various intensities for each element, the notion of a pixel group is completely discarded and each individual display element is individually addressed and individually assigned an intensity depending upon the predetermined line segment to be displayed and the orientation of that line segment wherein the method comprises generating element intensity, position and line slope information for a given line segment; inverting and registering the element intensity information; centering an array of elements around the element position information; determining the color of elements in the array of elements; determining the proper intensity for each element in the array of elements in order to produce the predetermined position of the line; and providing the proper intensity for each element and the array of elements in order to provide the proper line color.
