A practical standard for portable computer graphics data A concise guide to the Computer Graphics Metafile, a device‑independent way to store and transfer picture descriptions across graphics systems and installations.

This American National Standard defines a basic set of graphics elements and rules that help graphics data move easily between devices, software, and hardware. It describes a presentation‑level interface for graphics systems and outlines how to describe primitives, attributes, and the parameters that control how graphics are drawn. The goal is to enable consistent interpretation of graphics data and encourage a shared external format for wide device compatibility. It also positions CGM as a bridge to higher level standards and related graphics work, with coordination across several committees and ISO processes.

- Learn how CGM supports device‑independent picture description and transfer.
- Understand the core elements, attributes, and conventions used to render graphics consistently.
- See how this standard fits with other graphics standards and evolving technology.
- Gain context for portability, interoperability, and long‑term archiving of graphics data.

Ideal for readers of information processing standards, graphics practitioners, and developers building cross‑device graphics workflows.
