Method and apparatus for generating two-dimensional circuit pattern

A two-dimensional circuit pattern generating method of developing a circuit pattern constituted by plane figure including at least one oblique side into an image memory in which plural pixels are respectively equidistantly disposed in length and breadth directions,

• the method comprising:
• a first step of inputting coordinate values and external form dimensions of the plane figure;
• a second step of dividing the coordinate values and the external form dimensions by sizes (dimensions) of respective pixels given in advance to normalize them;
• a third step of judging whether or not respective sides constituting the plane figure are included within the pixel sizes;
• a fourth step of determining distances between the central point and the respective sides and angles thereof in the pixels which have been judged that the respective sides of the plane figure are included to judge whether or not data of the distances and the angles have been determined with respect to all pixels within which the respective sides are included;
• a fifth step of determining density values of the pixels by using the result of the distances and the angles determined at the fourth step;
• and
• a sixth step of outputting the density values determined at the fifth step to the image memory to generate a two-dimensional pattern within the image memory.
