PROBLEM TO BE SOLVED: To provide a method for generating drawing data for drawing a desired figure with a thick line having a predetermined width without generating pixels to be drawn twice, and to provide a data processor. SOLUTION: When drawing data of a circle A having a line thickness n is generated, a drawing coordinate generating program (13A) controls a computing process (S1) for the upper end yA and the lower end yB of the y-coordinates of pixels forming a first circle (21) and processes (S3, S5) for registering x-coordinates of the pixels that locate at the outermost position among the pixels forming the first circle and x-coordinates of the pixels that locate at the innermost position among the pixels forming a second circle (22) into a corresponding horizontal line drawing information buffer (11) for each y-coordinate from the upper end to the lower end. Using two registered x-coordinates as one pair, a pixel drawing program (14A) controls a process (S8) for generating drawing data from the coordinate point data from one coordinate point to the other included in the pair.
