26、oreword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technic
27、al committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part
28、in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approva
29、l by at least75% of the national bodies casting a vote. International Standard ISO/IEC12087-2was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 24, Computer graphics and image processing. ISO/IEC12087consists of the following parts, under the general tit
30、le Information technology Computer graphics and image processing Image processing and interchange (IPI) Functional specification: Part 1: Common architecture for imaging; Part 2: Programmers imaging kernel system application program interface; Part 3: Image Interchange Facility. Annex A, Annex G, An
31、nex H and Annex J form an integral part of this part of ISO/IEC 12087. Annex B, Annex C, Annex D, Annex E, Annex F, Annex K and Annex L are for information only.vi blankISO/IEC12087-2:1994(E) BSI 05-2000 1 1 Scope This part of ISO/IEC12087establishes the specification of the application program inte
32、rface (API), called the Programmers Imaging Kernel System (PIKS). ISO/IEC 12087-1 establishes the conceptual and architectural definitions of the Common Architecture for Imaging (CAI. ISO/IEC 12087-3 establishes the specification of the Image Interchange Facility (IIF). PIKS is intended to provide a
33、 rich set of both low-level and high-level services on image and image-derived data objects. These services can be used as building blocks for a broad range of common imaging applications. A conscious effort has been made by the developers of PIKS to create a standard that does not favor any particu
34、lar computing system. Implementations of PIKS should be possible on computing systems ranging in architecture from general purpose computers to specialised hardware accelerators, ranging in size from personal computers to mainframe supercomputers, and ranging in connectivity from stand-alone machine
35、s to distributed computing networks. Where applicable, PIKS relies on other APIs and data format standards to provide capabilities that are not unique to imaging. The following lists contain a summary of technological capabilities provided by PIKS and not provided by PIKS. However, it should be note
36、d that PIKS functionality may be useful as a pre-processor or co-processor for many of the technologies in the “Not provided by PIKS” list. NOTEThe Image Interchange Facility of ISO/IEC 12087-3 specifies image compression and decompression functionality and image transport between applications and b
