Character generation under grid constraints
An original and fast filling algorithm based on vertical scan line sweep and contour tracking of a presorted shape description allows filling of character shapes with real subpixel resolution. Identical parts of a character lying at a different phase in respect to the grid will have a dissimilar discrete look. Grid constraints are applied in order to force given parts of a character (stems, serifs) to attain identical phasing. So that several constraints may be applied, degrees of freedom are provided in the form of stretchable null-segments inserted at particular locations in the character outline description.
