Mobile Paper Style (PDF), standard as ISO 32000, is a data layout created by Adobe in 1992 for existing papers, consisting of message format and photos independent of software, equipment, and running systems. Based on the PostScript language, each PDF document envelops a total summary of a fixed-layout level record, consisting of the message, typefaces, vector graphics, raster pictures, and other info required to present it. PDF originates in "The Camelot Job," started by Adobe founder John Warnock in 1991.
