Establishes those functions of the Computer Graphics Interface concerned with virtual device management, coordinate space control, and error control.

This part of ISO/IEC 9636 establishes those functions of the Computer Graphics Interface concerned with Virtual Device management, coordinate space control, and error control.

The functionality incorporated in this part of ISO/IEC 9636 is concerned with the management of the graphics image and the interrelationship of the graphical and non-graphical parts of the interface.

This part of ISO/IEC 9636 is part 2 of ISO/IEC 9636, and should be read in conjunction with ISO/IEC 9636-1 and other parts. The relationship of this part of ISO/IEC 9636 to the other parts of ISO/IEC 9636 is described in ISO/IEC 9636-1 and in clause 4.

The functionality described in this part of ISO/IEC 9636 pertains to all classes of CGI Virtual Device (i.e. INPUT, OUTPUT, and OUTIN).
