Abstract: Methods disclosed permit the identification of frame buffer pixels for trapping. In some embodiments, flags associated with pixels in the frame buffer may be used to provide an indication of pixels for trapping. A first bit in a flag associated with a pixel may be set when the pixel is painted. In some embodiments, the method discloses a process for setting the value of a second bit in the flag to determine if the pixel associated with the flag lies on an object boundary. The pixel is identified as a candidate for trapping based on the value of the at least one flag.

Abstract: Systems and methods consistent with some embodiments of the present invention provide data structures and methods for the automatic storing, manipulating and processing of a intermediate printable data generated from a first printable data are presented. In some embodiments, the first printable data may take the form of a PDL description of a document and the intermediate printable data may take the form of a display list of objects generated from the PDL description. In some embodiments, a data structure for storing a intermediate printable data generated from a first printable data may comprise at least one memory pool, which may further comprise a plurality of uniformly sized segments to store the intermediate printable data; at least one global structure for storing information related to the one or more memory pools; and buffers for performing operations on the first printable data and the intermediate printable data.

Abstract: Systems and methods are provided for generating at least one look-up table, wherein the look-up table holds at least one luminance value in a second color space. In some embodiments, the luminance value can be computed for distinct combinations of color component values corresponding to a plurality of color components in a first color space. The method comprises computing at least one luminance value in the second color space based on a portion of the color component value combination; deriving an address in a look-up table based on the portion of the color component combination; and storing the computed luminance value in the look-up table at the derived address.

Abstract translation: 提供了用于生成至少一个查找表的系统和方法，其中查找表保存第二颜色空间中的至少一个亮度值。 在一些实施例中，可以针对对应于第一颜色空间中的多个颜色分量的颜色分量值的不同组合来计算亮度值。 该方法包括基于颜色分量值组合的一部分计算第二颜色空间中的至少一个亮度值; 基于颜色分量组合的部分在查找表中导出地址; 以及将所计算的亮度值存储在所述导出地址的所述查找表中。
