Abstract
A method for compressing font data wherein, for example, each byte of a font is provided with a compressing code. A bit map of the font is stored in a font file which is separated into a reference byte and a comparator byte. The two bytes are compared with each other. In response to the comparison a specific compression code is assigned and stored in the compression file. In the comparison, the present byte of a font to be compressed is compared with a byte which is positioned immediately before the present byte. When no byte is positioned immediately before the present byte, the byte is compared with OOH.
