摘要
The invention relates to methods, systems, and programming for producing and drawing subpixel-optimized bitmap images of shapes, such as fonts, by using non-linear color balancing. Some embodiments associate a luminosity with each subpixel of such an image as a function of (a) the percent of the subpixel's area covered by the shape and (b) the distribution to nearby subpixels of portions of the subpixel's resulting coverage value that cause color imbalance. Some embodiments distribute a subpixel's coverage value as a function of its difference from coverage values of other subpixels in the same pixel. Some embodiments draw a image comprised of pure foreground and background color pixels, as well as intermediary pixels in which subpixels are determined as a function of both foreground and background colors and color balancing. The intermediary pixels can, but need not, separate the foreground and background pixels along the direction of color balancing.
