1. A line symmetrical figure shaping apparatus, comprising:

  • inputting means for reading an input figure and generating a sequence of coordinate points thereof;

    storing means for storing the input figure and the sequence of coordinate points;

    feature point detecting means for detecting the coordinates of vertexes of the input figure, the maximum point values and the minimum point values in the horizontal direction and the vertical direction thereof with the sequence of coordinate points that are input by said inputting means and storing the coordinates of vertexes to said storing means;

    alternative symmetrical axis detecting means for detecting an alternative symmetrical axis for determining a symmetry of the input figure with the feature points;

    symmetry determining means for determining whether or not the input figure is symmetrical to the alternative symmetrical axis; and

    shaping means for shaping the input figure so that the input figure becomes symmetrical to the alternative symmetrical axis that has been determined to be symmetrical to the input figure by said symmetry determining means.
