  • Blank strip font compression method and device, and resulting stored, decompressible font
    Patent number: 5272768
    Abstract: The invented blank strip compression method recognizes that different font characters may have strips of blank data. For example, in the character ".sub.-- " the blank space above the character itself does not need to be stored in memory. The method identifies strips of blank and non-blank bit images that define characters and saves in memory only the bit images that are within the strips that include non-blank bit images resulting in a stored, decompressible font.
