The Computer Graphics Metafile (CGM) standard is used
in printing and graphics art applications that are either developed or acquired
for government use. It is strongly recommended when one or more of the
following situations exist. Graphics metafile is maintained at a central
facility for a decentralized system that employs graphics devices of different
makes and models that must utilize the data. Graphics metafile is required to
preserve picture data when conversion or migration from one graphics system to
another is necessary and the two systems are not necessarily compatible.
Graphics metafile is intended for information interchange between a source
system and a target system that are not necessarily compatible.
CGM provides portability of graphics data among
different software systems, graphical devices, and computer graphics
installations. Data interchange standard that defines a neutral
computer-interpretable representation of 2D graphical (pictorial) information
in a manner that is independent from any particular application or system.
The four parts of the standard are: Part 1,
Functional specification; Part 2, Character encoding; Part 3, Binary encoding;
and Part 4, Clear text encoding.
