【国外标准】 Information Technology ?Computer Graphics ?Interfacing Techniques for Dialogues with Graphical Devices (CGI) ?Functional Specification ?Part 1: Overview, Profiles and Conformance

ISO/IEC 9636 established the conceptual model, functional capability, and minimum conformance requirements of the Computer Graphics Interface (CGI). It specifies design requirements for encodings of the CGI. This part of ISO/IEC 9636 gives an overview of ISO/IEC 9636, explains the relationship between its parts and their relation to other standards, describes a reference model for graphics systems, and defines certain Foundation Constituency Profiles. ISO/IEC 9636-2, ISO/IEC 9636-3, ISO/IEC 9636-4, ISO/IEC 9636-5 and ISO/IEC 9636-6 specify the CGI functions for different functional areas using an abstract notation.
