Annex E

Specifies a language independent standard interface between device-independent and device-dependent parts of a graphics system. Coverage includes: events and event report lists; client program environment; implementation and host independencies. Also gives type definitions, table and annexes.

The Computer Graphics Interface (CGD (ISO/EEC 9636), specifies a language independent standard interface between device-independent and device-dependent parts of a graphics system. For integration into a programming language, CGI is embedded in a language dependent layer obeying the particular conventions of that language. This part of ISO/IEC 9638 specifies such a language dependent layer for the Ada programming language.
