Opis

The Computer Graphics Metafile (CGM) is an international standard for the storage of graphical data. The CGM can be used for storing pictures from a wide range of applications. A workshop was held at the National Bureau of Standards, Maryland, USA in September 1987 to discuss this newly adopted standard. The workshop brought together experts in the field. The papers presented included those from people who had been involved in developing the standard; those who were implementing it; those who were using it; those who could see future uses for this important standard; and those who may be involved in testing implementations. The book includes revised papers and records the discussions which resulted from them. This book presents a wealth of experience of the implementation and use of the CGM and supplies pointers to the future of standards work in this field. It is valuable information for implementors and users of the CGM and those involved in a consideration of testing.
