Grating processing method and device

Abstract

The present invention discloses a raster processing method and a device to improve data processing capacity of intelligent print data stream IPDS and make full use of processing capacity of the device. The method includes steps below: Receiving IPDS data, decomposing content data of the IPSD data into a plurality of IPDS data blocks and fulfilling raster operation to these IPDS data blocks. The present invention also discloses a raster processor.

Description

technical field [0001] The invention relates to the technical fields of computers and electronics, in particular to a rasterization processing method and device. Background technique [0002] Intelligent Printing Data Stream (Intelligent Printer Data Stream, IPDS) data is a printing protocol and description language based on the IBM mainframe, and is a streaming printing data. Different from other printing description languages, the IPDS host needs to establish a direct connection with the printing device at the beginning of the printing operation, and obtain the corresponding processing capability and corresponding physical characteristics from the printing device, and send the corresponding processing capability and physical characteristics to the printing device according to the obtained processing capability and physical characteristics. Send IPDS data to be processed for printing. [0003] IPDS RIP is a software for rasterizing IPDS data. It generates print-related ra...

Problems solved by technology

Only a part of IPDS data can be processed at a time. When the hardware equipment of the device running IPDS RIP has very high processing capacity, such as including multiple CPUs, the device still uses one CPU to process the part of IPDS data, and other CPUs may appear idle, resulting in waste of resources

[0005] Currently, the printing of IPDS data is generally used in black and white printing. At this time, the amount of IPDS data accounts for a small proportion of the overall throughput of the system. The serial processing method can meet the speed throughput requirements of most black and white printing equipment, but As the production process has more and more requirements for color, when supporting color IPDS data, the amount of corresponding color data will increase significantly compared with the amount of black and white data

At this time, the serial processing capability of IPDS RIP will not be able to meet the throughput requirements of the back-end high-speed equipment, especially when the medium of these high-speed output equipment is a roll medium, because the equipment cannot be stopped or started at any moment, this requirement is even more serious. obvious
