ISO/IEC 9636-2:1991 pdf download.Information technology — Computer graphics — Interfacing techniques for dialogues with graphical devices (CGI) — Functional specification — Part 2: Control.
ISO/IEC 9636-2:1991 describes the functions of the computer Graphics Inace concerned with Virtual Device management, coordinate space control, and error control.
The functionality incoporated in this part of ISO/ 936 is concemed with the management of the graphics image and the interrelationship of the graphical and non-graphical parts of the interface.
The functionality e d n his pa of ISO E 3 e ins to all classes of GI Viral Device.
This part of ISO/TEC 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 pan of ISO/IEC 9636 is concerned with the management of the graphics image and the interrelationship of the graphical arid nongraphical pans of the interface.
This part of ISOIIEC 9636 is part 2 of ISO/IEC 9636, and should be read in conjunction with ISO/EEC 9636-1 and other pans.
The relationship of this part of ISO/IEC 9636 to the other parts of ISO/EEC 9636 is described in ISO/EEC 9636-1 and in clause4.
The functionality described in this part of ISO/EEC 9636 pertains to all classes of CGI Virtual Device (i.e. INPUT, OUTPUT, and OUTIN).
This part of ISOIIEC 9636 defines those functions of the Computer Graphics Interface concerned with Virtual Device rnanagernenL, coordinate space control, and error control. The functionality incorporated iii this past of ISO/IEC 9636 is concerned with the management of the graphics image and the interrelationship of the graphical and non-graphical pans of the interface. This functionality is divided into the following areas:
— Virtual Device management functions, which allows the CGI client to initiate and terminate sessions of dialogue and to manage the graphics image on the Virtual Device.
— Coordinate space control functions, for the establishment of coordinate information, placement of the picture on the drawing surface, and for the management of drawing surface clipping.
— Error control functions, which involves the detection of errors both at and subsequent to the transmission of parameters through the CGI.
— Miscellaneous control functions, for the establishment of data stream numeric precisions, the accessing of implementation specific functionality, and the accessing of CGI external functions.
— Control inquiry functions, which provide access to the description tables and state lists concerned with function and Profile support, device description, and CGI control information.ISO/IEC 9636-2:1991 pdf download.
