Landmark Zycor Graphics File (ZGF) Reader

Licensing options for this format begin with FME Professional Edition.

The Landmark Zycor Graphics File (ZGF) Reader allows FME to read Zycor Graphics Files (ZGFs). The ZGF format is used by Zycor programs to store 2D graphics information.

Overview

ZGF is a two-dimensional (2D) system with no provision for storing user-defined attributes for the geometric data. A ZGF file has the following file name extension:

File Name Extension

Contents

.zgf

Vector geometric data

The extension is added to the basename of the ZGF file.

A ZGF contains one or more Major Graphics Units (MGUs), also called pictures. A picture is typically a basemap or contour map, although nothing prevents other types of pictures from being stored. Each picture is composed of one or more Logical Graphics Blocks (LGBs), also called segments. LGBs contain things such the map border, a title block, a contour, a posted well, etc. LGBs contain one or more graphic elements. There are six kinds of graphic elements: polyline, polygon, text, marker, clip window, and application data elements.
