Abstract:
In a computer implemented video display system, a method for generating an output character represented by bitmapped output scan lines from a corresponding input character represented by bitmapped input scan lines which have a different number of bits than the output scan lines, comprising the steps of:(a) providing a conversion table including entries which are addressable by at least a portion of an input scan line and contain a corresponding at least a portion of an output scan line; and(b) accessing the conversion table with the input scan lines to obtain corresponding output scan lines,wherein each input scan line includes one bit per pixel, and each output scan line includes two bits per pixel in which the two bits representing each pixel of the output character for which the input pixel has a first binary value have the first binary value, and the two bits representing each pixel of the output character for which the input pixel has a second binary value have a selected one of the second binary value, a third binary value and a fourth binary value.
