Abstract
A technique for efficiently drawing wide lines in a graphics display system by method and apparatus which includes identifying a wide line to be drawn; drawing a first line of pixels of a wide line; determining if a next line in the wide line has a different first coordinate value from a first coordinate value of the first line; generating at least one additional pixel value for the next line if the first coordinate value of the next line is different from the first coordinate value of an immediately previously drawn line; repeating the steps until the wide line has been completely drawn.
