In this paper, we propose a parameter extensible typeface definition method and its application to a font designing system. With this method, a user can easily define typefaces. In addition, two applications are developed for helping font definition. The former is the typeface designing tool to design the typeface, by which a user can easily make the definition graphically. The latter is the Open Type Font(OTF) creating system, which converts the typeface definition to OTF format file. The proposed method has the following four advantages. First, the cost for designing fonts is reduced from the conventional method. Second, by employing font parameters, it can express font transformations such as weight variations. Third, it can be easily defined graphically by using the tool. Fourth, a user can create OTF format file, which is standard format for font. Finally, we apply this method to a font designing system. According to the experimental results, we confirmed that the applied system excels the conventional one in respect of the quality, reflection of desired impression and the variety of the created fonts.
