Maruti: PS - Post Script

What is PostScript?

PostScript (PS) is a dynamically typed concatenative programming language created by John Warnock and Charles Geschke in 1982. PostScript is best known for its use as a page description language in the electronic and desktop publishing areas.

PostScript is a page description language (PDL) developed by Adobe. In essence, it is a programming language for describing how a page is to be printed or displayed. Examples of other PDLs include Envoy, PDF, and PCL. PostScript consists of functions for describing and positioning lines, shapes, fills, and other graphical elements, and for placing and formatting text.

Since PostScript describes the nature of a file's contents rather than just specifying how they look, PostScript content can be scaled effectively to any size. For example, a postcard-sized PostScript file could be expanded to the size of a billboard without any loss in quality.

PostScript files often have the file extension .ps or .eps.
