PURPOSE: To store a font in a large data size into a font cache memory without using a lot of memories.
CONSTITUTION: A font which data size is less than a prescribed value (≤2 kilobytes, for example,) are stored with bit map data in the case of storing the data of the font in the font cache memory and the font which data size is larger than the prescribed value, are stored with intermediate data. Since the amount of intermediate data is small even in the case of the font of large size, a lot of fonts can be stored, Then, time for obtaining the bit map data from the intermediate data is shorter in comparison with time for obtaining the bit map data from outline data. Therefore, a lot of fonts can be provided at high speed in comparison with a conventional font cache control system for storing only with the bit map data.
