Introduction

Ge is an editor to build operator graphics in ProviewR. The editor is integrated in the
ProviewR development environment and started from the Configurator. The graphs are built of
base objects in shapes of rectangles, circles, lines and texts, and of subgraphs, i.e. a
kind of composed object. Ge contains a collection of subgraphs for some common components:
valves, motors, pumps etc. Other components, the constructor can easily draw himself. The
shapes are stored as vectors, which makes it possible to scale and rotate the objects. In
runtime, a graph is opened from the Xtt operator environment or from the web operator
environment.
