ANTIALIASING COMPOSITION IN GRAPHIC OBJECT RENDERING

摘要

PROBLEM TO BE SOLVED: To provide an applicable composition method when a computer resource for image reproduction and rendering is limited when performing antialiasing. SOLUTION: In the method for performing antialiasing during scanning line rendering of a graphic object image, sub-pixel resolution coverage bit-masks(A-buffer) corresponding to the limited number of scanning lines is generated at a time in order to input image information and to perform the rendering of pixels from the inputted image information.
