Postscript level 1 color correction |
摘要 |
A PostScript-compatible printer accepts PostScript language commands that indicate both device-dependent and device-independent color specifications. Such a printer in accordance with the invention has a PostScript interpreter that implements Level 1 and Level 2 color rendering pipelines. In the Level 1 color rendering pipeline, the interpreter converts device-dependent color specifications to internal color specifications using a calibrated n-dimensional operation. In the Level 2 color rendering pipeline, the interpreter converts device-independent color specifications to device-dependent color specifications using a standard PostScript color rendering dictionary, and then passes such device-dependent color specifications into the Level 1 pipeline for further processing.
