Specifies a binary encoding of the Computer Graphics Metafile.

This part of ISO/IEC8632 specifies a binary encoding of the Computer Graphics Metafile. For each of the elements specified in ISO/IEC8632-1, this part specifies an encoding in terms of data types.

For each of these data types, an explicit representation in terms of bits, octets and words is specified. For some data types, the exact representation is a function of the precisions being used in the metafile, as recorded in the Metafile Descriptor.

This encoding of the Computer Graphics Metafile will, in many circumstances, minimize the effort required to generate and interpret the metafile.
