General

The Computer Graphics Metafile provides a file format suitable for the storage and retrieval of picture information. The file format consists of a set of elements that can be used to describe pictures in a way that is compatible between systems of different architectures and devices of differing capabilities and design.

The APV profile, described in this part of ISOLIEC 1207 1, defines a subset of CGM elements, sets limits and generation and interpretation behaviour according to the rules for profile definition defined in ISO/IEC 8632. The APV profile provides a CGM version 3 profile suitable for advanced presentation and visualization, such as imaging, scientific visualization.

Position within the taxonomy

APV is one of four core profiles defined within the taxonomy for CGM profiles These are shown in figure 1 in diagrammatic form the diagram uses the following conceptual framework to define profiles:

1) CGM version - this is a part of the standard and describes the group of elements available to the profile

2) complexity of the problem
