BS ISO/IEC 7942-1:1994

1   Scope This part of ISO/IEC 7942 specifies a set of functions for computer graphics programming, the Graphical Kernel System (GKS). It provides functions for two dimensional graphical output, the storage and dynamic modification of pictures , and operator input. GKS functions and datatypes are specified independently of programming languages. GKS establishes a system for device independent graphics programming by separating picture composition and interaction from the realization of the pictures on a specific output device and the input devices used by the operator. This International Standard is applicable to a wide range of applications that produce two dimensional pictures on vector or raster graphical devices in monochrome or colour. Operator interaction is allowed with these pictures .
