- Scope
- 1 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 AST 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 AST profile defines a version 2 CGM suitable for use in advanced scientific and technical graphics, for example CAD, mapping, earth sciences. 2 Position within the taxonomy AST 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: 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 The four core profiles (as indicated in Figure 1) are: Taxonomy Profile Name: identifier: 1 FCG-11 Basic Scientific and Technical graphics (BST) e.g. business presentation graphics, simple desk top publishing 2 FCG-23 Advanced Scientific and Technical graphics (AST) e.g. CAD, mapping, earth sciences 3 FCG-32 Basic Presentation and Visualization —the Model Profile from the CGM standard, e.g. graphics arts, high end desk top publishing 4 FCG-33 Advanced Presentation and Visualization (APV) e.g. imaging, scientific visualization. This part of ISO/IEC ISP 12071 defines the AST profile. 3 User requirements and scenario This part of ISO/IEC ISP 12071 provides a profile, AST, which is suitable for advanced scientific and technical graphics, for example CAD, mapping, earth sciences.
