I asked a question about using the image operator to produce color images instead of grey scale. In the meantime I browsed the Adobe documents server (ps-file-server@adobe.com) and found a document called Color Extensions (dated 23-jan-1990) describing some new PostScript operators including colorimage and setcolortransfer The first is analagous to image but uses RGB or CMYK input, and the latter is an expansion of settransfer to four color components. Color PostScript printers are going to become more common, so will these operators be in NeWS? David Burgess ===== Astronomy Unit, QMW, University of London +44 71 975 5460

These operators are not very useful in the window system context since they deal in 24 and 32 bits per pixel to define the image. Thus they will not be in Version 2 of OpenWindows, but may appear in later releases as TrueColor framebuffers become more common. ______________________________________________________________________ Patrick J.
