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 f 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 thh direction of color balancing.

摘要： The invention relates to methods, systems, and programming for producing and displaying subpixel-optimized images and digital content including such images. Some embodiments access digital content represented by a mark-up language and display it with its images scaled down in a subpixel-optimized manner in a format dictated by the mark-up language. Some embodiments produce subpixel-optimized images by calculating the luminosity of a subpixel in such an image as a function of the length of a plurality of coverage lines within a window in a source image corresponding to the subpixel that is covered by source image pixels having the subpixel's color. Some embodiments calculate the luminosity of a subpixel in a subpixel-optimized image as a function both of the average luminosity of pixels in the subpixel's source image window and as a function of any color balancing distribution between resulting subpixel luminosities necessary to reduce color imbalance.

摘要： The invention relates to methods, systems, and programming for displaying media in a scaled-down manner. In some embodiments one web page layout is displayed at different scales, with different pixel resolution bitmaps used for images and fonts at each different scale, and with the shape and pixel alignment of font bitmaps of the same character being varied to improve readability at each scale. In some embodiments a user can select text from one of multiple columns of a web page's display and have it re-laid out and displayed at a larger font size relative to a column width that fills at least 2/3 of the display's width. In some embodiments a web page can be selectively displayed in different layouts in which images and text have different sizes relative to the layout space and different pixel resolutions, and in which text flows differently across line boundaries.

摘要： An outline representation of a character or symbol is treated as being composed of a set of zones formed in both the horizontal and vertical directions. The zones are completely character-specific. Each zone defines the extent of some feature of the character. The boundaries of the zones are mapped to specific pixel locations in a bitmap em-square of selected resolution and size. Additional interpolation zones are defined which are used to map all the points on the outline representation of the character that are contained within the interpolation zone, but do not coincide with a control edge, from the positions in the high-resolution em-square to a corrresponding position in the low-resolution em-square. To maintain relationships between features, constraint functions may be defined which regulate the size of the control zones for a character at predetermined sizes. Control zones and interpolation zones are all derivatively linked to a basic set of horizontal and vertical control edges at the outline description level. Consequently, the number of computations needed is reduced and the speed with which a bitmap can be generated from the outline representation is increased.

摘要： Une représentation des contours d'un caractère ou d'un symbole est traitée comme étant composée d'une hiérarchie de zones dans les sens horizontal et vertical. Les zones sont tout à fait spécifiques aux caractères. Chaque zone définit l'étendue d'un trait particulier du caractère. Les limites des zones sont attribuées à des points spécifiques dans un cadratin en mode point ayant une résolution et des dimensions sélectionnées. Les points disponibles sont alors alloués aux zones. Une fois que chaque niveau de zone a reçu son allocation de point, les points ainsi assignés sont distribués parmi le prochain niveau inférieur de zone et le processus se répète itérativement jusqu'à ce que toutes les zones aient reçu leurs allocations de points ou qu'il ne soit plus possible d'allouer des points. Afin de maintenir des relations entre certains traits particuliers, les traits particuliers des caractères (aussi bien à l'intérieur de caractères individuels qu'entre différents caractères) peuvent être reliés de façon à être définis en termes des traits particuliers du même caractère ou d'autres caractères. Les traits particuliers sont reliés au niveau de la description des contours, de sorte que leur liaison ne doive être spécifiée qu'une seule fois et soit utile par la suite à chaque fois que l'on veut générer un graphique en mode point à partir du contour.

摘要： A computerized system receives characters (219), each having an associated font (217). For each character-font combination received it accesses a pre-defined font description (in 122) of that combination's shape (453) and then generates a new font description (in 126) of that shape. Preferably when the characters have different fonts, the system automatically creates new font descriptions for all of them. Preferably the received characters are part of an input text (116), and the system produces an output text (104) which includes not only corresponding characters (219A), but also the new font descriptions necessary to define those character's shape. Preferably the output text can be transferred to other computers by recording media (130) or computer network (132). Preferably the new font descriptions are independent of the manner in which pre-defined font descriptions define character-font shapes. Preferably the system can render an image (in 110) of the output text, either on the computer which created it (102A, 102B), or on another computer (108A, 108B).

摘要： An outline representation of a character or symbol is treated as being composed of a hierarchy of zones formed in both the horizontal and vertical directions. The zones are completely character-specific. Each zone defines the extent of some feature of the character. The boundaries of the zones are mapped to specific pixel locations in a bitmap em-square of selected resolution and size. The available pixels are then allocated to the zones. After each level of zone has received its pixel allocation, the pixels assigned thereto are then distributed among the next lower level of zones and the process is repeated iteratively until all zones have received their pixel allocations or it is no longer possible to make allocations. To maintain relationships between features, features of characters (both within individual characters and between different characters) may be linked so as to be defined in terms of the features of the same or other characters. The features are linked at the outline description level, so that the linking need be specified only once and will thereafter be useful any time a bitmap is to be generated from the outline.

摘要： A method of producing a sub pixel resolution representation of a shape suitable for display on a sub pixel addressed screen. The method comprises producing a scaled sub pixel optimized image of a bitmap image by associating a luminosity value with each sub pixel of the scaled image as a function of the percent of the area of the sub pixel's area in the image that is covered by the shape and a color balancing function designed to distribute a portion of a sub pixel's luminosity value that otherwise would cause color imbalance to nearby sub pixels of different colors. The percent of a sub pixel's luminosity values that is so distributed is a function of the percent of the sub pixel's luminosity value, which causes color imbalance. An advantage is that it reduces the amount of luminosity value distributed for color balance purposes to approximately only that amount which is necessary to achieve color balance, and increases the clarity of sub pixel optimized images.
