  • Patent number: 4314244
    Abstract: A system and method for generating properly proportioned alphanumeric characters and symbols in two vertical heights with a single character generator and a minimum of associated circuitry. The bits of video data stored in the character generator are stored such that the vertical segments of diagonal portions of the characters and symbols include no more than two bits per vertical segment of the diagonal portion. The video data bits representative of the pels of circular portions of the symbols are stored in an arrangement to generate a horizontally elongated elliptical shape when the character or symbol is displayed in the shorter of the two heights. Whenever possible, the diagonal portions of characters include no more than two diagonally disposed pels in the single high character size.
