ABSTRACT:
A coordinate address is generated which specifies the position in a square original tile area where pattern data is to be written for each pixel, and a check is made to determine if the coordinate address is adjacent any one of sides of the original tile area. When the written pixel is adjacent any one of sides of the original tile area, the position of a pixel is calculated which is adjacent the written pixel on another tile area adjacent the original tile area along that side, and the position of the adjacent pixel when the adjacent tile area is laid on the original tile area is calculated as a shifted position of the adjacent pixel. The positions of the written pixel and the shifted position are rotated predetermined angle about the center of a polygon at least once to obtain rotational positions. Pixel values are additionally written at these shift and rotational positions.
