Disclosure Full
Description Encapsulated Postscript (EPS) is a page description format, developed by Adobe Systems Incorporated. Version 3, the third version of the format, was developed in 1992, and subsequently revised in 1999 to include a number of extensions and features of the PostScript language not previously documented. An EPS file comprises a header section followed by a PostScript document. The header can refer to version 3.0 or version 3.1. An EPS can optionally include a preview raster image, in which case a binary header is prepended to the header.
