This National Standard of Canada is equivalent to International Standard ISO/IEC 8632-3:1999. 1 Scope This part of ISO/IEC 8632 specifies a binary encoding of the Computer Graphics Metafile. For each of the elements specified in ISO/IEC 8632-1, this part specifies an encoding in terms of data types. For each of these data types, an explicit representation in terms of bits, octets and words is specified. For some data types, the exact representation is a function of the precisions being used in the metafile, as recorded in the Metafile Descriptor. This encoding of the Computer Graphics Metafile will, in many cir cumstances, minimize the effort required to generate and interpret the metafile.

This National Standard of Canada is equivalent to International Standard ISO/IEC 8632-1:1999. 1 Scope ISO/IEC 8632 provides a file format suitable for the storage and retrieval of picture description information. The file format consists of an ordered set of elements that may be used to describe pictures in a way that is compatible between systems of different architectures, compatible with devices of differing capa bilities and design, and meaningful to application constituencies. This picture description includes the capability for describing static images. The elements specified provide for the representation of a wide range of pictures on a wide range of graphical devices. The elements are organized into groups that delimit major structures (metafiles, pictures, and application structures), that specify the representations used within the metafile, that control the display of the picture, that perform basic drawing actions, that control the attributes of the basic drawing actions, that allow application-specific structuring to be overlaid on the graphical content, and that provide access to non-standard device capabilities. The metafile is defined in such a way that, in addition to sequential access to the whole metafile, random access to individual pictures and individual context-independent application structures is well-defined. Applications which require random access to pictures and/or context-independent application structures within pictures may, within the metafile, define directories to these pictures and/or context-independent application structures. The metafile may then be opened and randomly accessed without interpreting the entire metafile. In addition to a functional specification, two standard encod ings of the metafile syntax are specified. These encodings address the needs of applications that require small metafile size plus minimum effort to generate and interpret, and maximum flexibility for a human reader or editor of the metafile. This part of ISO/IEC 8632 describes the format using an abstract syntax. The remaining parts of ISO 8632 specify standardized encodings that conform to this syntax: ISO/IEC 8632-3 specifies a binary encoding; ISO/IEC 8632-4 specifies a clear text encoding.

This National Standard of Canada is equivalent to International Standard ISO/IEC 8632-4:1999. 1 Scope This part of ISO/IEC 8632 specifies a clear text encoding of the Computer Graphics Metafile. For each of the elements specified in ISO/IEC 8632-1, a clear text encoding is specified. Allowed abbreviations are specified. The overall format of the metafile and the means by which comments may be interspersed in the me tafile is specified. This encoding of the CGM allows metafiles to be created and maintained in a form which is simple to type, easy to edit and convenient to read.

This National Standard of Canada is equivalent to International Standard ISO/IEC 12089:1997. 1 Scope This International Standard defines the encoding rules which shall apply to the representation of IPI-IIF image data. The IPI-IIF data format is defined in ISO/IEC 12087-3, called Image Interchange Facility (IIF). It is Part 3 of the Image Processing and Interchange International Standard, defined in ISO/IEC 12087. The IPI-IIF facilitates the interchange of digital images. It consists of two major Parts: (1) the IPI-IIF data format (IIF-DF) definition, whose syntax is described using ASN.1; (2) the IPI-IIF gateway definition, whose functionality is described by an application programmers interface. The IPI-IIF is based on the definition described in Part 1, Common Architecture for Imaging (CAI) of the ISO/IEC 12087. Due to the fact that the syntax of the IIF-DF is expressed using the Abstract Syntax Notation One (ASN.l), defined by ISO/IEC 8824, this Standard makes use of the Basic Encoding Rules (BER) for ASN.1, by referring to ISO/IEC 8825 for the definition of encoding rules. NOTE - A rationale for the introduction of new encoding rules in addition to those defined by the BER is given in clause 4. Reference shall be made to this International Standard, and its definitions shall be employed, whenever images are interchanged, according to the IIF-DF, defined in ISO/IEC 12087-3.

This National Standard of Canada is equivalent to International Standard ISO/IEC 12087-3:1995 (first edition, 1995-02-15). 1 Scope This part of ISO/IEC 12087 facilitates the interchange of digital images. For this purpose, conceptual, architectural, and functional definitions of the Image Interchange Facility (IPI- IIF) are established. ISO/IEC 12087-3 consists of two major parts, the: a) IIF data format (IIF-DF) definition (by means of a formal syntax, described according to the Abstract Syntax Notation One (ASN. 1) -- refer to clause 5), and the b) IIF Gateway definition (by means of a manual page description of the functionality of an Application Program Interface (API) - - refer to clause 7). An IPI-IIF-conformant implementation has to fulfill the functionality specification of the IIF Gateway, as outlined in clause 7. Besides the IIF Gateway, there may be information processing systems (software such as parsers, generators, etc.) which read and/or write the IIF-DF. The IPI-IIF is based on the definitions described in ISO/IEC 12087-1, the Common Architecture for Imaging. The IPI-IIF, as a whole, may be characterized briefly as follows: c) By means of the IIF data format and Gateway, image data objects and image-related data objects are transported to and from application environments. d) By means of the full PIKS Profile of the IPI-IIF data format (i.e., a format for data interchange between IPI-IIF and IPI- PIKS), image data objects and image-related data objects are imported to and exported from the Programmer's Imaging Kernel System (IPI-PIKS), defined in ISO/IEC 12087-2. e) The IPI-IIF facilitates the storage of image data objects and image-related data objects in a variety of pre-defined storage modalities, including different periodicity organizations, such as pixel-interleaving or band-interleaving. f) This part of ISO/IEC 12087 defines syntax of image data (and image-related data) streams. The encoding of IIF data types is defined in ISO/IEC 12089. See also 5.3.3. g) The IPI-IIF supports a concept of standardized conformance profiles. Initially, three conformance profiles are defined within ISO/IEC 12087. h) An IIF data stream may be stored in devices such as file systems. An IIF data stream may be interchanged and communicated in data networks (e.g., LANs and WANs) or in other data communication facilities. All low-level data storage and transfer is delegated, for instance, to the operating system of the target hardware. i) The IIF Gateway performs compression and decompression of image d ata objects using standardized compression and decompression techniques. These techniques are referenced in this part of ISO/IEC 12087. See 1.4.5 and 5.3.3 and 7.5 for further definition. j) The IIF Gateway is accessible via an API to perform image interchange functions. See clause 7 for a definition of IIF Gateway functionality. Reference shall be made to this part of ISO/IEC 12087, and its definitions shall be employed, whenever images are interchanged, according to the IPI-IIF, among different imaging applications environments or among imaging devices. The IPI-IIF is applicable t o scenarios requiring the interchange of digital images, as outlined in Annex C. The use of the IIF data format as a superset of the functionality of most of the existing image interchange formats solves the Problem of application-independent syntactical and semantical interpretation and understanding of image data. The IPI-IIF is applicable to image interchange in and among different application domains. The following application areas have been considered: - Medical imaging - Remote sensing - Publishing - Industrial vision - Computer graphics arts - Computer animation - Scientific visualization - Mission planning - Document processing - Outdoor scene surveillance The limiting of the IPI-IIF scope to certain application domains is a matter of profiling. This is treated in clause 6. NOTE - Whether an image interchange format may also be regarded as a device format, depends on the (local) processing power of the device itself. Thus a conceptually high-level format which has become an industrial standard page description language for desktop electronic publishing, can be regarded as a device format. The IPI-IIF may well be considered a device format if, for instance, there is an IPI-IIF-compatible printer which is abl e to receive, process, and hardcopy an image according to the IPI-IIF. In the same sense, it is reasonable to design IPI- IIF-compatible image sources, e.g. IPI-IIF camera systems.
