The Graphics System

A simple efficient graphics system (LG: the ``Light Graphics'' system) has been written to allow graphical output to X-11 displays and PostScript files. This replaces the previous commercial system.

LG is similar in concept to, but not the same as GKS (``The Graphics Kernel System''), an international standard for 2-D computer graphics. LG allows a device independent interface, but has extra functionality for more efficient use of the underlying hardware.

The system tries to be close to WYSIWYG (``What You See Is What You Get''), but the limitations of X-11 or the PostScript printer will lead to some differences.

The new system allows many advantages and allows similar appearance of the graphical output, but is quite different in some important aspects.
