[L. postscriptus, (assumed) p. p. of postscribere to write after; post after scribere to write: cf. F. postscriptum. See {Post-}, and {Scribe}.] A paragraph added to a letter after it is concluded and signed by the writer; an addition made to a book or composition after the main body of the work has been finished, containing something omitted, or something new occurring to the writer. [Abbrev. P. S.] [1913 Webster] 53 Moby Thesaurus words for "postscript": PS, Parthian shot, addendum, affix, afterthought, allonge, appendix, back matter, chorus, coda, codicil, colophon, commentary, conclusion, consequence, continuance, continuation, double take, dying words, enclitic, envoi, epilogue, follow-through, follow-up, infix, interlineation, interpolation, last words, marginalia, note, parting shot, peroration, postface, postfix, postlude, prefix, proclitic, refrain, rider, scholia, second thought, sequel, sequela, sequelae, sequelant, sequent, sequitur, subscript, suffix, supplement, swan song, tag, tail on work originally done by John Gaffney at Evans and Sutherland in 1976, evolving through "JaM" ("John and Martin", Martin Newell) at {XEROX PARC}, and finally implemented in its current form by John Warnock et al. after he and Chuck Geschke founded {Adobe Systems, Inc.} in 1982. PostScript is an {interpreted}, {stack-based language} (like {FORTH}). It was used as a page description language by the {Apple LaserWriter}, and now many {laser printers} and on-screen graphics systems. Its primary application is to describe the appearance of text, graphical shapes, and sampled {images} on printed or displayed pages. A program in PostScript can communicate a document description from a composition system to a printing system in a device-independent way. PostScript is an unusually powerful printer language because it is a full programming language, rather than a series of low-level escape sequences. (In this it parallels {Emacs}, which exploited a similar insight about editing tasks). It is also noteworthy for implementing on-the fly {rasterisation}, from {Bezier curve} descriptions, of high-quality {fonts} at low (e.g. 300 dpi) resolution (it was formerly believed that hand-tuned {bitmap fonts} were required for this task). PostScript's combination of technical merits and widespread availability made it the language of choice for graphical output until {PDF} appeared. The {Postscript point}, 1/72 inch, is slightly different from other {point} units. {An introduction (http://cs.indiana.edu/docproject/programming/postscript/postscript.html)}. ["PostScript Language Reference Manual" ("The Red Book"), Adobe Systems, A-W 1985]. [{Jargon File}] (2002-03-11) PostScript: n. A page description language, based on work originally done by John
Gaffney at Evans and Sutherland in 1976, evolving through ‘JaM’ (‘John and Martin’, Martin Newell) at XEROX PARC, and finally implemented in its current form by John Warnock et al. after he and Chuck Geschke founded Adobe Systems Incorporated in 1982. PostScript gets its leverage by using a full programming language, rather than a series of low-level escape sequences, to describe an image to be printed on a laser printer or other output device (in this it parallels EMACS, which exploited a similar insight about editing tasks). It is also noteworthy for implementing on-the fly rasterization, from Bezier curve descriptions, of high-quality fonts at low (e.g. 300 dpi) resolution (it was formerly believed that hand-tuned bitmap fonts were required for this task). Hackers consider PostScript to be among the most elegant hacks of all time, and the combination of technical merits and widespread availability has made PostScript the language of choice for graphical output.
