Computer Graphics Metafile (CGM)

It was little used outside these markets and is essentially obsolete today except insofar as it is the underlying API defining the Computer Graphics Metafile.

The critics state the standard should instead have referenced the platform neutral standard ISO/IEC 8632 "Computer Graphics Metafile".

Computer Graphics Metafile (CGM) (file format for 2D vector graphics, raster graphics, and text defined by ISO/IEC 8632)

In the original release the difference between this standard and others like it is that the graphics structures were exclusively defined as CCITT raster image and Computer Graphics Metafile (CGM - ISO 8632).
