ISO/IEC 8632的这一部分规定了计算机图形元文件的二进制编码。对于每个 ISO/IEC 8632-1中规定的元素，本部分规定了数据类型的编码。 对于这些数据类型中的每一种，都指定了位、八位字节和字的显式表示。对一些人来说 数据类型，精确表示是元文件中使用的精度的函数，如 元文件描述符。 在许多情况下，对计算机图形图元文件的这种编码将最大限度地减少生成图形所需的工作量 生成并解释图元文件。

This part of ISO/IEC 8632 specifies a binary encoding of the Computer Graphics Metafile. For each of the elements specified in ISO/IEC 8632-1, 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.
