Annex B (informative) - Clear text encoding example

Specifies a clear text encoding of the Computer Graphics Metafile (CGM). This CGM encoding allows metafiles to be created and maintained in a form which is easy to edit, simple to type and convenient to read. Also specifies the overall format of the metafile and the means by which the comments may be interspersed in the metafile.

This part of ISO/IEC8632 specifies a clear text encoding of the Computer Graphics Metafile. For each of the elements specified in ISO/IEC8632-1, a clear text encoding is specified. Allowed abbreviations are specified. The overall format of the metafile and the means by which comments may be interspersed in the metafile is specified.

This encoding of the CGM allows metafiles to be created and maintained in a form which is simple to type, easy to edit and convenient to read.
