Application Summary AI generated

This standard specifies a clear text encoding method for the Computer Graphics Metafile (CGM), allowing picture description information to be stored and transferred in a human-readable text format. It is applied in software development and data exchange contexts where graphical data needs to be manually inspected, edited, or debugged, such as in CAD, technical illustration, and graphic design systems. The encoding facilitates interoperability between different computer graphics applications by providing a non-binary, character-based representation of vector images and associated metadata.
