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 BST profile, described in this part of ISO/IEC 12071, 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 BST profile defines a version 1 CGM suitable for use in basic scientific and technical graphics applications, such as business graphics, simple desktop publishing.

Position within the taxonomy

BST is one of four core profiles defined within the taxonomy for CGM profiles. These are shown in Figure 1 in diagramatic form. The diagram uses the following conceptual framework to define profiles:

• CGM version — this is a part of the standard and describes the group of elements available to the profile
• complexity of the problem

The four core profiles (as indicated in Figure 1) are:

This part of ISO/IEC ISP 12071 defines the BST profile.

User requirements and scenario

This part of ISO/IEC ISP 12071 defines the BST profile.

This part of ISOLIEC ISP 12071 provides a profile, BST, which has limited capability and is suitable for basic scientific and technical graphics, e.g. business presentation graphics, simple desk top publishing.
