ABSTRACT:
The invention provides a graphic form shaping apparatus which shapes, when a graphic form having certain symmetry with respect to a line and surrounded by a curved line is inputted, the input graphic form so as to be symmetrical with respect to a line. Apexes and maximal points and minimal points in horizontal and vertical directions of an input graphic form are determined as characteristic points, and the degree of symmetry with respect to a straight line interconnecting two of the characteristic points is measured. If the degree of symmetry satisfies a criterion determined in advance, then it is determined that the input graphic form is symmetrical with respect to the straight line, and the input graphic form is corrected based on the symmetry with respect of the straight line.
