Abstract

This paper investigates aliasing along straight line segments or edges and its origin, and how it is affected by the orientation or slope of the segment. A method for anti-aliasing or smoothing the straight line segments by modifying the intensity of the pixels is presented and this paper proposes a line drawing scheme to draw a line by calculating deflection-angle and error to draw the next possible pixel more accurately both starting from co-ordinate point (x1,y1) (x2,y2) to meet mid (m), so that there will be a pattern of pixels nearer to the imaginary line. The basis of the algorithm is to draw pairs of pixels from both the end points straddling the line.
