摘要： One embodiment comprises a system that stores a pre-defined color conversion table and a hash table. The system receives user-defined color conversions for a print job, stores them in first locations in the hash table, and marks the first locations as persistent. The system processes the print job utilizing the color conversion table to convert colors in the print job to the output color space, and responsive to encountering colors in the print job that do not have color conversions in the color conversion table, interpolates between color conversions in the color conversion table to generate new color conversions, stores the new color conversions in second locations in the hash table, and marks the second locations as non-persistent. The system determines that the hash table is to be re-initialized, allows reuse of the second locations in the hash table, and prevents reuse of the first locations in the hash table.

摘要： Embodiments described herein provide for the reuse of some locations in a hash table of color conversions during processing of a print job, while preventing the reuse of other locations. If a determination is made that the hash table is to be re-initialized, then the locations in the hash table that are marked as non-persistent are marked as saved to allow them to be reused, while the locations in the hash table that are marked as persistent are prevented from being reused. During processing of the print job subsequent to re-initialization of the hash table, if a color in the print job does not have a color conversion, then a location in the hash table is identified that is marked as saved. If the location stores the color conversion for the color, then the non-persistent mark is restored for the location to bypass performing a color conversion for the color.

摘要： A printer is described. The printer includes a processor. A memory is coupled to the processor. The memory contains instructions that when processed by the processor cause a method to be performed. The method includes presenting a list of printing substitutions on a display. The printing substitutions are each associated with a respective printer profile. The list of printing substitutions identify which ones of the printing substitutions are enabled and which ones of the printing substitutions are disabled. The list also identifies the printer profiles that the substitutions are associated with, wherein at least one printer profile that is not enabled for a current print job is included in the list.

摘要： A method and apparatus for managing complex presentation objects using globally-unique identifiers. Downloaded objects are identified by globally-unique identifiers to maintain object integrity and to facilitate capturing downloaded objects for reuse without additional download time overhead. An object may be referenced by selected indicia, such as a name, a globally-unique identifier or a globally-unique identifier and an object locator, The object is located by the selected indicia. Then, a decision is made whether to allow capture of the object based upon whether the selected indicia includes a globally-unique identifier and is secure.

摘要： A method of compressing pixel information is described. The pixel data is received in a data stream and compressed into a compressed data format by identifying a run of consecutive bytes of the data stream based on the similarity of the consecutive data bytes in the data stream. A mode bit of a compression byte is used to indicate whether a run of consecutive bytes is identified. Count bits of the compression byte are used to indicate the number of times the data bytes are repeated and zero counts may be used to indicate particular types of runs, for example, runs to the end of a scan line and the end of an object. Where a pixel byte is represented by 8 bits, the data stream may be compressed in multiples of four bytes at a time. If a pixel is represent by less than 8 bits, the compression method may look for repetitions of similar bytes one byte at a time.
摘要翻译： 描述压缩像素信息的方法。 基于数据流中的连续数据字节的相似度，通过识别数据流的连续字节的运行，将数据流中的像素数据接收并压缩为压缩数据格式。 压缩字节的模式位用于指示是否识别连续字节的运行。 压缩字节的计数位用于指示重复数据字节的次数，零计数可用于指示特定类型的运行，例如，运行到扫描线的末尾和对象的结尾。 在像素字节由8位表示的情况下，数据流可以一次被压缩成四个字节的倍数。 如果一个像素低于8位，则压缩方法可以一次查找一个字节的类似字节的重复。
