Скачать или смотреть Raster image processor

A raster image processor is a component used in a printing system which produces a raster image also known as a bitmap. Such a bitmap is used by later stage of the printing system to produce the printed output. The input may be a page description in a high-level page description language such as PostScript, Portable Document Format, XPS or another bitmap of higher or lower resolution than the output device. In the latter case, the RIP applies either smoothing or interpolation algorithms to the input bitmap to generate the output bitmap.
Originally RIPs were a rack of electronic hardware which received the page description via some interface and generated a "hardware bitmap output" which was used to enable or disable each pixel on a real-time output device such as an optical film recorder.
