Abstract

PURPOSE:To represent the inflection point information of a wide range and to attain a large data compression by defining a format setting block and a data block to be one unit and storing one contour information for plural units. CONSTITUTION:The format setting block and the data block are defined to be the one unit and respective units are set for respective formats A-Z to constitute so as to store the one contour information (Fig, I). In such a way, in the example of Fig. II, the coordinate range is X:0-639, Y:0-339, according to the conventional method, four bytes as the total of the respective two bytes of X, Y coordinates are required in order to represent the one coordinate and at the time of outputting Z coordinate values as the contour information, the quantity of the data is 4Z byte. However, in Fig. II, since all the contour information is situated within the range of X:0-255, Y:0-255, when a two byte absolute coordinate representing form is selected in the setting block, the quantity of the data is 2Z + 2 bytes and when Z is completely large, it is about half of the conventional method. According to the setting of the setting block, the range of X:0-639, Y:0-399 can be represented.
