ABSTRACT:
A line symmetrical graphic arrangement device comprises a characteristic quantity computing unit for computing characteristic quantity depending on the shape of an input graphic and selecting a characteristic point used for the graphic arrangement, a proposed symmetry axis computing unit and a symmetry judging unit for requiring proposed symmetry axes of the input graphic based on the characteristic of the shape and the quality of the symmetry axes in the input graphic, a base point computing unit and an axis angle deciding unit for modifying the proposed symmetry axes on the basis of the quality of the symmetry axes, so as to obtain the symmetry axes of the input graphic, and a characteristic point position computing unit for relocating the characteristic points selected by the characteristic quantity computing means with the obtained symmetry axes as reference, so as to create a symmetrical graphic with respect to the symmetry axes.
