发明名称 ANTI-ALIAS FONT GENERATION
摘要 A method of generating a second, substantially anti-aliased, representation of a character from a first representation. The second representation is comprised of horizontal lines of dots that are shifted horizontally relative to dots of the first representation, each dot of the first representation having a value DOT1 associated therewith. The method include a step of, for each horizontal line (1-m) within the first representation of a character and for each dot (1-j) within a horizontal line, (a) determining a modifying value (DOT1k) associated with a dot (k) of the first representation, DOT1k being a function of DOT1 of the dot(k). The method includes another step of determining a value (DOT2k) of a corresponding dot for the second representation, the value of the corresponding dot being determined in accordance with the expression DOT2k = (( DOT1 - DOT1k ) + DOT1(k-1) ), where DOT1(k-1) is a modifying value of an adjacent dot on the horizontal line. The modifying value is preferably determined by a table lookup procedure within a table of previously generated values.
