CGM: Computer Graphics Metafile



CGM files are vector graphic files useful as clipart. They scale well, and have the distinction of being the only ANSI standard graphic format. There are many flavors of CGM files; ThumbsPlus supports the most popular for PCs (binary encoding), with the following limitations:


Embedded cell arrays (bitmaps) are not supported.
New (version 3) extensions, such as Bézier curves, are not supported.
Font support is improved yet still incomplete.
Rotated (non-orthogonal) ellipses and elliptical arcs are not correctly rendered.
Hatches are rendered with the closest hatching format available from Windows.
