    • A raster image processing system and method that can keep up with the fastest high resolution printers now available can process images "on the fly"--that is, generate images from compact input representations so rapidly that printing can occur substantially in the same real time as raster image processing of input data. This system is capable of automatically "screening" data relating to the images so that the various gray scales or color levels are correct for a contone printing process. Different print engine control modules can be replaceably plugged into and out of the system to allow it to be used with different types of print engines/intelligent imaging systems--including high speed, high resolution color printing engines. A high speed data cache and associated array disk drive provide high speed throughput of data into the system. The disk array may, for example, store a library of high resolution graphics that can be accessed "on the fly" as needed in response to the input data stream. A graphics accelerator can generate, on the fly, many "primitive" or simple graphics (e.g, angles, lines, boxes, etc.) at the same time that the remainder of the print image is being generated.
    • 可以跟上目前可用的最快的高分辨率打印机的光栅图像处理系统和方法可以“即时”处理图像,即,快速地从紧凑的输入表示生成图像,使得打印可以基本上以相同的实时发生 输入数据的光栅图像处理。 该系统能够自动地“筛选”与图像相关的数据,使得各种灰度级或颜色级别对于连续色调打印处理是正确的。 不同的打印引擎控制模块可以可替换地插入和退出系统,以允许它与不同类型的打印引擎/智能成像系统(包括高速,高分辨率彩色打印引擎)一起使用。 高速数据缓存和相关的阵列磁盘驱动器可将数据的高速吞吐量提供给系统。 例如,磁盘阵列可以存储可响应于输入数据流根据需要“快速”访问的高分辨率图形库。 在生成打印图像的其余部分的同时,图形加速器可以生成许多“原始”或简单图形(例如,角度,线条,框等)。
