Embodiment Construction

[0049] The specific embodiments of the present invention will be described below in conjunction with the drawings.

[0050] The present invention aims at the technical defects existing in the existing single-machine RIP system, and aims to provide a method for improving the performance of the single-machine RIP system. The method can dynamically support the parallel operation of multiple RIP process instances according to the current computer's single-machine hardware configuration, and ensure that the CPU that supports multitasking on the computer can allocate multiple RIP process instances to run. Maximize the overall operating performance of the stand-alone RIP system.

[0051] figure 1 It is a schematic flow diagram of the implementation principle of the present invention. As shown in the figure, after the print job data is input, several RIP instance processes are controlled to be processed in parallel. After the processing is completed, the rasterized dot matrix data is un...

Abstract

The invention discloses a parallel raster image processing method and system under a CPU supporting multi-task in graphic image printing processing, comprising: starting a plurality of raster image processing processes according to the detected number of tasks supported by the CPU; Distribute print jobs; each raster image processing process stores the raster dot matrix data interpreted by the job into the raster data area; and outputs the raster dot matrix data in the raster data area uniformly. The invention has great flexibility, and can flexibly configure the grating image processing process along with the upgrading of new computer hardware. At the same time, the invention is applicable to a stand-alone raster image processing system with any hardware configuration, so as to improve the performance of the stand-alone raster image processing system.

Description

Technical field [0001] The invention relates to a parallel raster image processing method and system, in particular to a parallel raster image processing method and system under a CPU supporting multiple tasks in graphic image printing processing. Background technique [0002] RIP (Raster Image Processing), the full name of raster image processing. The role of RIP in the color desktop publishing system is very important. It is related to the output quality and speed, and even the operating environment of the entire system. It can be said to be the core of the color desktop publishing system. The main function of RIP is to interpret the various images, graphics and text in the computer-made layout into dot matrix information that can be recorded by a printer or imagesetter, and then control the printer or imagesetter to record the image dot matrix information on paper or film. [0003] RIP is usually divided into hardware RIP (hard RIP) and software RIP (soft RIP), and there are a...
