摘要： A method, apparatus, and information bearing medium for compressing color utilizes an expandable color palette for storing a pre-established number of n-bit color codes. Each of the n-bit color codes maps to an m-bit color value, where m is an integer greater than n. Up to the pre-established number of n-bit color codes are stored in a first palette table of the color palette. The color palette is expanded to include up to a specified number of palette tables for storing sets of the pre-established number of n-bit color codes. The pre-established number of n-bit color codes is characterized by 2n−1 color codes. The color palette is expanded to include up to (m/n)−1 palette tables for storing sets of 2n−1 color codes. Each of the palette tables is associated with a pixel table which stores a linking value for associating a particular palette table to a subsequently generated palette table.

摘要： Methods and systems herein provide for efficiently resolving how a rasterizer responds to out of memory conditions when attempting to write raster data to a solid state memory. In one embodiment, a print controller determines that the solid state memory is no longer available for storing raster data. The print controller determines that a process is utilizing the shared memory to complete an operation, where completing the operation frees up a portion of the solid state memory. The print controller suspends the rasterizer from writing raster data to a hard disk, and waits for the process to complete the operation. The print controller then instructs the rasterizer to resume writing raster data to the solid state memory.

摘要： Printing systems, print controllers, and associated methods of partitioning sheetside bitmaps are disclosed. A print controller in one embodiment connects to a plurality of printhead controllers that are operable to control a plurality of printhead arrays. The print controller includes an interpreter system operable to receive a print job, and to convert an image in the print job into a full sheetside bitmap comprised of an array of pixels. The print controller also includes a partitioning system operable to process the full sheetside bitmap to identify the pixels in the full sheetside bitmap designated for printing on each of the printhead arrays, and to generate a partitioned sheetside bitmap for each printhead array that contains essentially the pixels designated for printing on the printhead array. The print controller further includes an interface system operable to transmit the partitioned sheetside bitmaps to the printhead controllers associated with the printhead arrays.

摘要： Non integer scaling of images to reduce artifacts is presented herein. One embodiment includes determining a scaling resolution based on a pixel resolution of the image and a pixel resolution of an output device (i.e., factors of the scaling resolution). The image is converted to the scaling resolution to change (e.g., increase) the pixels of the image by the first factor. A grid is generated to scale the converted image. The grid has a number of sections defined according to the second factor times the pixel resolution of an output device. The converted image is sectioned according to the grid. Each section of the grid includes an integer number of pixels of the converted image. The color values of the pixels of the converted image are averaged within each section of the grid to compute a single color value for each section of the grid and scale the image.

摘要： Systems and methods are provided for processing a logical page in parallel with graphics for the sheet that are defined in a job ticket. The system includes multiple parallel Raster Image Processors (RIPs) and a control system. The control system receives print data and a job ticket, identifies a graphic that is associated with a logical page and defined in the job ticket, and transmits the logical page to a parallel RIP for processing. The parallel RIP determines page dimensions from the logical page, transmits the page dimensions, and rasterizes the logical page. The control system determines a location for the graphic based upon the transmitted page dimensions, and directs another RIP to rasterize the graphic in order to generate a rasterized graphic in parallel with the RIP that is rasterizing the logical page.

摘要： A command is provided as a means to instruct a printer to pre-rasterize and store presentation objects according to specified presentation parameters. The stored rasterized objects are available to the printer for use during printing when a print job is submitted to the printer which includes a presentation object already rasterized, saving significant processing at print time. The rasterized objects are stored with information identifying the object and the parameters used in the rasterization process and the printer is enabled to identify the appropriate rasterized object for inclusion in the print job. Objects may also be selected by a printer at print time as most closely matching the required parameters and then adjusted as needed at print time to completely conform with the requirements of inclusion in the job. This capability allows the printer to perform trimming-on-the-fly or other real-time operations while enjoying the time-saving benefits of a pre-rasterized object.
摘要翻译：提供命令作为指示打印机根据指定的呈现参数预光栅化和存储呈现对象的手段。当将打印作业提交到包括已经光栅化的演示对象的打印机时，存储的光栅化对象可供打印机使用以在打印期间使用，从而在打印时保存显着的处理。光栅化对象被存储有识别对象的信息和在光栅化过程中使用的参数，并且打印机被启用以识别包含在打印作业中的适当的光栅化对象。打印机也可以通过打印机在打印时选择对象，最符合要求的参数，然后在打印时根据需要进行调整，以完全符合包含在作业中的要求。该功能允许打印机在实现光栅化前的对象的同时享受节省时间的优势，即时执行修整或其他实时操作。

摘要： Systems and methods are provided for implementing adaptive rasterized print data management. The printing system is able to acquire a print job and instructions for printing multiple copies of the job. The control unit is also able to initiate processing of a first copy of the print job, to instruct a Raster Image Processor (RIP) to rasterize a data segment of the print job, and to determine a transfer time to transfer the rasterized data segment to a marking engine if it were stored at the first memory. Further, the control unit is able to determine a threshold value, and to facilitate storage of the rasterized data segment at the second memory if the transfer time is greater than the threshold value.
