CHARACTERISTICS

File extension .pdf Internet media type application/pdf Description: PDF is the
Portable Document Format developed by Adobe Systems. It was invented to
streamline the process of sharing and viewing files independent of any software,
OS or hardware. Individuals can use PDFs wherever and whenever they want on any
device. PDF files can contain textual and visual data as well as links, buttons
and more. PDFs can be also password protected and edited with special programs.
Technical Details: Graphics are represented in PDF very similarly to that of
PostScript. PDF graphics use a device-independent Cartesian coordinate system
which describes the surface of a page. The page description uses a matrix to
scale, rotate, or skew graphical elements. The graphics state is a collection of
graphical parameters that may be changed, saved, and restored by a page
description. Developed by ISO Initial Release: 15 June 1993 Useful links:
