Embodiment Construction

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

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

[0051] Fig. 1 is a schematic flow chart 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 process them in parallel, and after the processing is completed, the dot matrix data obtained by rasterizat...

Abstract

The invention discloses a parallel-raster image processing method and system when a CPU supports multi-tasks during the course of image print processing; the method includes the steps that a plurality of courses of raster image processing can start according to the detected number of the tasks supported by the CPU; printing work is handed out to each course of raster image processing; the printing work is explained into spot-array raster data, and then be stored in the raster data field by each course of raster image processing; spot-array raster data stored in the raster data field can be output as a whole; with great flexibility, the invention can allocate the courses of raster image processing flexibly with the upgrade of the new hardware of computers; in addition, the invention is applicable to raster image processing system of single chip computer with any configuration to improve the performance of raster image processing system of single chip computer.

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 multitasking 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 quality and speed of the output, and even the operating environment of the entire system. It can be said that it is the core of the color desktop publishing system. The main function of RIP is to interpret various images, graphics and texts 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), an...
