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.
摘要翻译：一种产生适于在子像素寻址屏幕上显示的形状的子像素分辨率表示的方法。该方法包括通过将亮度值与缩放图像的每个子像素相关联来产生位图图像的缩放的子像素优化图像，作为被形状覆盖的图像中的子像素区域的百分比的函数以及设计用于分配子像素的亮度值的一部分的颜色平衡功能，否则将导致颜色不平衡到不同颜色的附近子像素。如此分布的子像素的亮度值的百分比是子像素的亮度值的百分比的函数，这导致颜色不平衡。一个优点是，它将色彩平衡目的分配的亮度值的量减少到仅实现色彩平衡所需的量，并且增加了子像素优化图像的清晰度。

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.

摘要： A computerized system inputs fonted text and outputs corresponding fonted text containing new, automatically created, font descriptions. The new font descriptions make the output a portable document which can be rendered at any magnification by a machine of any output resolution, even if that machine does do not have access to the pre-defined font descriptions associated with the original input text. The system creates the portable document by accessing the pre-defined font descriptions of each character-font shape in the input text and generating new font descriptions which describe those shapes in a new font description language. Preferably the system findspoints on the outlines of each character-font shape which are a function of the shape itself, rather than how its pre-defined description describes that shape. The system bases the segmentation of the new font description on such description-independent points. Once created, the portable document can be rendered on the computer or printer generating it or a computer or printer receiving the document over a network or on mass storage media. In some embodiments, the computer viewing the portable document determines whether can access and render the pre-defined font description of each character in the portable document. If so, it does so. If not, it interprets the shape of the character from its new font description in the portable document.

摘要： 2030533 9012386 PCTABS00002 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.
