Abstract:
A method for rendering the middle of a line using a matrix of pixels, wherein the line extends in the positive-x direction and positive-y direction or extends in the negative-x direction and positive-y direction, wherein the line has an absolute value of its slope between 0 and 1 and a current pixel has been defined, the method including:for each column containing a portion of the middle of the line: plotting a first pixel, the first pixel being a pixel which best represents the location of the line in the column; plotting a second pixel above the first pixel; assigning a normalized intensity value between 0 and 1.0 to the first pixel according to the amount of area above the line in the first pixel; assigning a normalized intensity value for the second pixel equal to 1.0 minus the normalized intensity value of the first pixel; and shading the first and second pixels according to the normalized intensity values.
