36、hat are members of ISO 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. ISO and IEC technical committees collaborate in fields of mutual interest. Other int

37、ernational organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of international technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC I. Draft International Standards adopted by the joint technical commit

40、face Part 3: Image Interchange Facility (IIF) Annex A forms an integral part of this part of ISO/IEC 12087. Annexes B to G are for information only. iv ISOIIEC 12087-3:1995(E) Introduction ISO/IEC 12087-1 establishes the conceptual and architectural framework for ISO/IEC 12087. In particular, it def

41、ines the types of all image data objects, image-related data objects, and attributes that may be interchanged by means of the IPI-lIF. ISO/IEC 12087-2 establishes the specification of the Programmers Imaging Kernel System (IPI-PIKS). ISO/IEC 12087-3 provides a data format specification and an applic

42、ation program interface specification. The lIF data format may be used for image data interchange in open, heterogeneous environments. It may also serve as a local file format for imaging applications, especially in conjunction with ISO/IEC 12087-2. In future, the IIF data format could be used by te

43、lecommunication standards. Examples are future versions of File Transfer, Access, and Management (FT AM), ISO/IEC 8571; the Message Oriented Text Interchange Systems (MOTIS), ISO/IEC 10021 (also known as Message Handling System (MHS), CCnT Recommendation X.400). Thus the IIF data format could become

44、 part of application-oriented OSI communications protocols. Within the IIF data format (IIF-DF), compressed images may be specified and interchanged. For this purpose, the following standards are referenced: CCITT Recs. T.4 and T.6 (Facsimile) ISO/IEC 11544 (JBIG) ISO/IEC 109 18 (JPEG) ISO/IEC I 1 1

45、72 (MPEG-I ) Image data streams that conform to the encoded representation of compressed image data specified by these standards may be included in the IIF-DF. For instance, a time series image can be represented as an array of time slices, each of which is encoded according to the JPEG Standard. Fu

46、rthermore, the IIF-DF allows images to be represented through the combination of compressed parts with uncompressed parts. It is also possible to use multiple compression methods within a single IIF-DF-conformant image. For instance, a colour image can be represented as tiled images whereby some til

47、es are encoded according to the lossy mode of the JPEG Standard and others according to the lossless mode. For detailed information concerning compressed data streams and compression/decompression functionality, refer to 5.3.3 and 7.1.6, respectively. There are various possibilities for interaction

48、and data exchange between the IPI-PIKS domain and the IPI IIF domain. Both domains are controlled by the application via application program interfaces (APIs). For a detailed description of the interworking between the IPI-PIKS and the IPI-IIF refer to clause 4 (the IPI IIF architecture) and clause

49、7 (the IPI-IIF Gateway functionality). For a description of the relation between the types of objects that may be interchanged by means of the IPI-IIF and those types of objects that may be processed by the IPI-PIKS, refer to clause 6 (the profiles for the IIF data format). Refer also to ISO/IEC 12087-1. v ISOIIEC 12087-3:1995(E) vi INTERNATIONAL STANDARD ISOIIEC ISOIIEC 12087-3:1995(E) Information technology - Computer graphics and image processing - Image Processing and Interchange (IPI) Functional specification Part 3: Image Interchange Facility (II
