An antialias line generator has a line sequencer for performing axis interpolation, an intension interpolator for performing intension interpolation, and a write axis calculator for producing information about two pixels constituting opposite ends of a line during one machine clock on the basis of interpolation information obtained from the line interpolator and intension interpolator. With the above construction, axis interpolation is carried out by applying start and end points of the line to the line interpolator, intension interpolation is carried out by applying a pixel intensity to the intension interpolator, axes of two pixels constituting the opposite ends of the line are calculated by applying the line axis obtained from the line interpolator and a related axis obtained from the intension interpolator to the write axis calculator, and a smooth line can be drawn by writing an actual pixel on the basis of the drawing intensity data obtained from the intension interpolator and a drawing axis data signal obtained from the write axis calculator.
