readme.txt describes in some detail the six file images provided here. There are three CGMs (Computer Graphics Metafiles) in this collection.

allprims.cgm

This CGM file is interesting for two reasons: it contains at least one instance of 18 of the 19 graphical primitives of Version 1 metafiles of CGM:1992--Polyline, Polymarker, Text, Polygon Set, Cell Array, Elliptical Arc Close, etc.--plus a good sampling of the 35 attribute elements; and, it is in the Clear Text encoding so you can read the contents and see what CGM structure and elements look like.

corvette.cgm

This file is a good example of typical CGM use in graphic arts applications. This file is a Binary-encoded CGM. It is drawn entirely using color filled polygons, rectangles, circles, and ellipses, plus lines and text (and associated attributes). Extensive use is made of color.

techdraw.cgm

This file is a good example of the typical use of CGM in electronic documents, comprising SGML for revisable text, and CGM for revisable vector and raster graphics. The picture is a typical technical illustration from an aircraft maintenance manual.

allprims.sum
corvette.sum
techdraw.sum

The above three files are summary reports produced by the MetaCheck (TM) product, indicating at a summary level what each file contains and whether it is a valid metafile.
