  • Character multifont compression and restoration device
    Patent number: 5027304
    Abstract: A realtime generating system for generating printed Chinese characters with multifonts and multiresolutions, includes a Chinese character compression sub-system and a printed Chinese character realtime generating sub-system. The former sub-system is used to compress the dot matrix characters into a character vector, and to store the character vector in the ROM (read only memory) of the latter sub-system. The compressed character vector is retrieved from the ROM and converted into a character outline in accordance with a Chinese character code and the specific resolution. The character outline is then processed through the steps of enlarging or shrinking, and filling to form a printed Chinese character.
