  • Method of modifying the fatness of characters to be output on a raster output device
    Patent number: 5673371
    Abstract: Font data which defines the shape of each character as an outline consisting of straight and curved line segments is transformed into bitmap representations of the individual characters such that the fatness of the character in the bitmap differs from that of the original font character by a predetermined fattening distance (f) by determining a modified outline on the basis of the font data and the fattening distance (f), and then compiling the bitmap representation by filling the modified outline with discrete pixels.
