what is postscript
PostScript (PS) is a computer language for creating vector graphics. It is a dynamically typed, concatenative programming language and was created by John Warnock, Charles Geschke, Doug Brotz, Ed Taft and Bill Paxton in 1982. It is used as a page description language in the electronic and desktop publishing areas.lmost as complex as PostScript itself is its handling of fonts. The font system uses the PS graphics primitives to draw glyphs as line art, which can then be rendered at any resolution.
