| Abstract: | There are two methods to get the vector Chinese characters:Digitizing and Raster-to-vector Conversion.After a general view of these methods,a new Raster-to-vector Con-version method based on the Minimal First Conversion of 8-neighbor Adjacent Matrix is derived.In order to efficiently solve the boundary conversion of a dot Chinese character,the method of Enlarged Matrix is proposed.Some other Raster-to-vector Conversion methods(i.e.distance transformation,skeleton,border following,ect) are also discuss-ed.The formulas of geometric transformation for locating and directing the characters in a drawing is given by means of an azimuthal angle.Using above conclusions,the author and his colleagues have successfully designed the online and offline functions of |
