41、 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 collaborate in fields of mutual int

42、erest. 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 Standards adopted by the joint te

43、chnical committee are circulated to national bodies for voting. Publication as an International Standard requires approvaI by at least 75 % of the national bodies casting a vote. International Standard ISO/IEC 12087- 1 was prepared by Joint Technical Committee ISODEC JTC 1, Information technology, S

44、ubcommittee SC 24, Computer graphics and image processing. ISOAEC 12087 consists of the following parts, under the general title Information technology - Computer graphics and image processing - Image processing and interchange (IPI) - Functional specification: - Part 1: Common architecture for imag

45、ing - Part 2: Programmers imaging kernel system application programme interface - Part 3: Image Interchange Facility (IIF) Annexes A to D form an integral part of this part of ISO/IEC 12087. Annex E is for information only. vi ISOAEC ISOAEC 12087-1 :I 995 (E Introduction The processing of images is

46、a requirement of many application areas of information processing. Early work in these areas led to the development of many application program interfaces and a large number of image representations for interchange. The purpose of ISOAEC 12087 is to provide an application program interface and an im

47、age interchange representation in order to increase the portability of application software. ISOflEC 12087 provides an architectural model for the representation and manipulation of images in a digital form. Based on this model, it defines an application program interface and an image interchange fo

48、rmat. It is applicable to all application areas that involve the processing, manipulation, or transfer of image data. ISOAEC 12087 includes notes and exemplary material. Such material is non-normative: it is included solely to aid understanding and does not form part of ISOAEC 22087. ISOAEC 12087 in

49、itially comprises three parts: 1 Common architecture for imaging, which describes the common architectural material on which the entire Standard is based; 2 Programmers imaging kernel system application program inferface, which defines processing opera- tions to be carried out on image data; 3 Image Interchange Facility (IIF), which defines how images may be interchanged between application programs. Information may be interchanged between the application program, Programmers Imaging Kernel System (IPI-PIKS), and Image Interchange Facility (IPI-IF) (see figure ).
