ABSTRACT:
A method and apparatus for processing a character for anti-aliased display on a raster output device. A set of density values is computed for a set of raster positions to represent the character and the density values of the set are scaled to extend their range upward toward a maximum density value, whereby generally at least one of the density values of the set becomes the maximum density value. In one embodiment, the set of density values is computed from a rendering of the character at resolution higher than the resolution of the output device. In another embodiment, the character is created by a font having font metrics including a reference dimension, and the density values are scaled by computing adjusted values as a non-decreasing function of the original values, the function being defined to compute a maximum adjusted density value for at least one non-maximum density value.
