<p>Das <b>Computer Graphics Metafile</b>-Format (CGM) ist ein <a href="Offenes_Format" title="Offenes Format">freies</a>, <a href="Offener_Standard" title="Offener Standard">offenes</a> und <a href="Internationale_Organisation_f%C3%BCr_Normung" title="Internationale Organisation für Normung">international standardisiertes</a> Datei-Format für 2D-Grafiken, welches definiert und genormt ist nach <b><a href="International_Organization_for_Standardization" class="mw-redirect" title="International Organization for Standardization">ISO</a>/<a href="International_Electrotechnical_Commission" title="International Electrotechnical Commission">IEC</a> 8632</b>.<sup id="cite_ref-ISO-8632_3-0" class="reference"><a href="#cite_note-ISO-8632-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> CGM wird in vielen verschiedenen <a href="Industrie" title="Industrie">Industriezweigen</a> als Standard-Format für geräteunabhängige, zweidimensionale <a href="Grafikformat" title="Grafikformat">Grafik-Daten</a> verwendet. Es handelt sich um ein <a href="Vektorgrafik" title="Vektorgrafik">vektorbasiertes Grafikformat</a>. Es enthält typischerweise Informationen über <a href="Polygon" title="Polygon">Polygone</a>, <a href="Kurve_(Mathematik)" title="Kurve (Mathematik)">Linien</a> und <a href="Text" title="Text">Text</a> mit Eigenschaften wie <a href="Farbe" title="Farbe">Farbe</a> und <a href="Quantit%C3%A4t" title="Quantität">Größe</a>.

<div class="mw-heading mw-heading2"><h2 id="Versionen">Versionen</h2></div>
<ul><li>Version 1: (1987)</li></ul>
<dl><dd>Standardisierung durch <a href="American_National_Standards_Institute" title="American National Standards Institute">ANSI</a> und <a href="International_Organization_for_Standardization" class="mw-redirect" title="International Organization for Standardization">ISO</a> als Norm ISO/IEC 8632-1.</dd></dl>
<ul><li>Version 2: (1990)</li></ul>
<dl><dd>Einführung von Segmenten und wiederverwendbaren Gruppen.</dd></dl>
<ul><li>Version 3: (1992)</li></ul>
<dl><dd>Erweiterung durch Polybézier-Kurven und Rastergrafik-Elemente. Einführung von <i>Application Profiles</i>.</dd></dl>
<ul><li>Version 4: (1995)</li></ul>
<dl><dd>Erweiterung um <i>Application Structures</i>, Hotspots, Hyperlinks etc.</dd></dl>
<p>Durch die letzten Erweiterungen erhalten CGM-Dateien eine wachsende Bedeutung in Web-Umgebungen. Dort wird das WebCGM-Format z. B. dazu verwendet, Grafiken in interaktiven elektronischen <a href="Verzeichnis" title="Verzeichnis">Katalogen</a> und <a href="Handbuch" title="Handbuch">Handbüchern</a> darzustellen.

<div class="mw-heading mw-heading2"><h2 id="Software">Software</h2></div>
<p>In der Regel werden die Illustrationen nach bestimmten Regeln (z. B. wie in der <a href="S1000D" title="S1000D">S1000D</a> beschrieben) in einer Grafik-Software erstellt. Anschließend werden sie dort heraus in das Format CGM exportiert. Der Illustrator erhält dazu vom Auftraggeber der Illustration die Exportdetails, wie etwa das Profil (z. B. S1000D V 4.2) und die CGM-Version (z. B. Version 4).
