1. A method of filling an inner region of a graphic with traces of an imaging spot having a predetermined spot size, on an image plane of said graphic, said method comprising the steps of:

  • (a) preparing graphic data which define border lines of said graphic,(b) on the basis of said graphic data, dividing said graphic into convex loops only along lines which are parallel to a predetermined direction,(c) detecting respective longitudinal directions of said convex loops,(d) with respect to each of said convex loops, generating an array of vectors convering an inner region of each such convex loop, with vectors belonging to said array having components in a longitudinal direction of said convex loop and being spacedly arrayed in a direction transverse to said vectors, the spacing between said vectors corresponding to said spot size, and(e) serially moving said imaging spot on said image plane along said vectors to thereby fill said inner region of said graphic.
