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： A method is described that includes defining a window of one or more consecutive pixel values in a linear array of pixel values of an image. The defining includes adding a pixel value in the linear array to the window so long as the pixel value does not deviate from the pixel values that exist within the window to a degree that causes a threshold value to be exceeded, and, wherein the threshold value decreases as the size of the window increases. The method also includes encoding the window of pixel values with a value determined from pixel values within the window and the number of pixel values within the window.

The code is preferably Unicode, and the complex text data is preferably Unicode complex text. The printer includes a font, a text parser, and a layout engine. The font includes a plurality of glyphs. The text parser parses the data stream to determine the section of complex text data in the data stream. The layout engine is coupled to the text parser and with the font. The layout engine receives the section of complex text data from the text parser and determines at least one of the plurality of glyphs and glyph positions corresponding to the section of complex text data.

摘要： Methods and apparatus for using meta-data structures to represent portions of a bitmap memory when generating the sheetside image and when generating a compressed representation of the sheetside image. A table of meta-data structures is maintained with each structure corresponding to a portion of the bitmap memory. Data objects representing a sheetside image are processed by determining which portions the data object would affect, by updating the meta-data structures corresponding to affected portions to indicate whether the affect generates a “compact” type of data or a “non-compact” type of data, and for the “non-compact” types of data writing data to the bitmap memory. For portions having “compact” type of data, the corresponding meta-data structures alone describes the bitmap portion of data. A compressed-bitmap generator then uses the meta-data structures and the portions of the bitmap memory containing “non-compact” data to generate a compressed representation of the sheetside image.

摘要： A system, method, and processor-readable medium provide for compressing color data involves a number of pixels defining a region of a display area. The pixel data for each of the pixels includes color data and control data. The control data of particular pixels, having color data not used to contribute to a color of an object in a display area region, is set to a transparent setting. The color data of the particular pixels is set to a selected color code for the entire region and subject to compression. In another embodiment, the particular pixels may include color data not used to contribute to a color of a first object or a second object in the display area region. The color data of particular pixels defining the first object is set to a first color code. The color data of particular pixels defining the second object is set to a second color code. The color data is switched between the first and second color codes at a selected pixel position. The color data of the particular pixels for the first and second display areas is compressed using the respective first and second color codes. Color compression may involve merging the second object of the second color with the first object of the first color.
