15、or worldwide standardization. National bodies that are members of IS0 or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. IS0 and IEC technical committees collab
16、orate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work. In the field of information technology, IS0 and IEC have established a joint technical committee ISO/IEC JTC 1. Draft International Stand
17、ards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75% of the national bodies casting a vote. International Standard ISO/IEC 9973 was prepared by Joint Technical Committee ISOAEC JTC 1, In
18、formation technology, Subcommittee SC 24, Computer graphics and image processing. This first edition cancels and replaces ISO/TR 9973: 1990. Annex A forms an integral part of this International Standard. Annexes B to E are for information only. . 111 ISO/IEC 9973:1994 (E) 0 ISO/IEC Introduction This
19、 International Standard has been published to provide a set of procedures for the registration of graphical items. In this context graphical items refers to all registered graphical items defined within the standards developed by ISO/IEC JTCUSC24. These procedures were originally processed by IS0 TC
20、97/SC21/WG2 (now ISO/IEC JTCUSC24) as a Technical Report. Although it was originally published as a Technical Report because its prompt availability was critical to the utilization of existing International Standards, it is now recognized that the importance of this material merits its publication a
21、s an International Standard. Responsibility for preparing standards for interchange of information involving computer graphics is assigned to subcommittee ISO/IEC JTCl/SC24 - Computer Graphics and Image Processing. All proposed and anticipated standards in this area share certain classes of graphica
22、l items that are allowed to vary across implementations of the standard: linetype is an example of such a class. Nevertheless, there is a strong incentive for implementations using the same graphical items to reference them in the same way. Each standard developed by ISO/IEC JTCl/SC24, therefore, pr
23、ovides for registration of certain graphical items. For example, in the Graphical Kernel System, linetype values 1,2,3, and 4 are defined in the International Standard; linetype values 5 and greater are reserved for registration, and negative values are used for implementation dependent linetypes. T
24、his International Standard specifies procedures to be followed in preparing, maintaining and publishing the ISO/IEC International Register of Graphical Items, containing the identifiers and meanings assigned to particular items. The purpose of the register is to inform all concerned of items already
25、 registered and of the specific identifiers assigned to them. The register includes current classes of graphical items and registered graphical items for relevant International Standards developed by ISO/IEC JTCUSC24. It will be updated as necessary for future computer graphic standards developed by
26、 ISO/IEC JTCUSC24. Publication of the register promotes compatibility of international information exchange and avoids duplication of effort in development of application-oriented graphical items. Registration provides identification for a graphical item but should not be regarded as a standardizati
27、on procedure. However, as a matter apart from registration, the graphical items may, but need not, be the subject of an international, national, or other standard. In these cases the register will reference the applicable standard. When such a standard is prepared subsequent to registration of a gra
28、phical item, it would be appropriate for the registered identifier of the graphical item to be indicated in the standard. iv INTERNATIONAL STANDARD 0 ISO/IEC ISO/IEC 9973: 1994(E) Information technology - Computer graphics and image processing - Procedures for registration of graphical items 1 Scope
29、 This International Standard specifies procedures to be followed in preparing, maintaining, and publishing a register of identifiers and meanings that, under the direction of ISO/IEC JTCUSC24, are assigned to graphical items. Registration procedures will not assign values of identifiers for graphica
30、l items that are defined as being workstation- or implementation-dependent by specific graphics standards. The register of font appearance in the ISO/IEC JTCUSC24 register of graphical items is not intended to address the broader issues of general purpose font registration as provided by ISO/IEC JTC
31、l/SC18. The procedures apply to registration of individual items within classes of graphical items as reserved for registration in the International Standards developed by ISO/IEC JTCUSC24. 1 ISO/IEC 9973:1994 (E) 0 ISO/IEC 2 Normative references The following standards contain provisions which, thr
