ARCHIVED: What is PostScript?
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 files often have the file
.eps, and consist of
functions for describing and positioning lines, shapes, fills, and
other graphical elements, as well as 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, postcard-sized content in a PostScript file could be expanded to the size of a billboard without any loss in quality.
