What is a CGM made of?

CGM files typically contain elements like polygons, lines, and text with properties attributed to elements such as color, and size.

Binary CGM efficiently combines text, vector graphics, raster cells and industry specific extensions at an arbitrary or specific scale.

CGM History & Profiles

CGM version 1 developed by ANSI and ISO in 1986 (ISO 8632:1987). Designed as a graphical file exchange and printing format for CAD systems.

CGM version 3 defined in 1992 (ISO 8632:1992). Enhances CGM with advanced primitives such as splines and polybezier curves, & tiled raster for image data.

CGM version 4 defined in 1999 (ISO 8632:1999). Adds application structuring so that a CGM file can contain non-graphical information such as part numbers, descriptions, signatures, notes, etc. This gives CGM files intelligence, so that you can drill into a graphic for more detailed information. Ideal for Web publications.
