11、 of ITU-T Recommendations I International Standard. Development of these Recornmendations I International Standard was originally in parallel with ECMA 101 : 1989, Open Document Architecture. This set of ITU-T Recommendations I International Standard replaces the CCITT T.4 1 O-Series of Recommendati

12、ons (1988) and IS0 8613: 1989. Significant technical changes are the inclusion in this Recommendation I International Standard of the following amendments as agreed by ITU-TS and ISO/IEC JTC 1 : - Tiled raster graphics; - Colour. In addition, a number of technical corrigenda have been applied to the

13、 Specification. This part contains three annexes: - Annex A (integral) contains a summary of the raster graphics content architecture classes; Annex B (non-integral) lists the ASN.1 object identifiers used by the raster graphics content architecture; Annex C (integral to ISO/IEC only) contains ODL,

14、the SGML representation of the attributes specific to raster graphics content architectures. - . Vlll ISO/IEC 8613-7 : 1994 (E) INTERNATIONAL STANDARD ITU-T RECOMMENDATION 1 INFORMATION TECHNOLOGY - OPEN DOCUMENT ARCHITECTURE (ODA) AND INTERCHANGE FORMAT: RASTER GRAPHICS CONTENT ARCHITECTURES Scope

15、The purpose of the ITU-T Rec. TAlO-Series I ISO/IEC 8613 is to facilitate the interchange of documents. In the context of these Recommendations I International Standards, documents are considered to be items such as memoranda, letters, invoices, forms and reports, which may include pictures and tabu

16、lar material. The content elements used within the documents may include graphic characters, geometric graphics elements and raster graphics elements, all potentially within one document. NOTE - These Recommendations I International Standards are designed to allow for extensions, including hypermedi

17、a features, spreadsheets and additional types of content such as audio and video. In addition to the content types defined in these specifications, ODA also provides for arbitrary content types to be included in documents. These Recommendations I International Standards apply to the interchange of d

18、ocuments by means of data communications or the exchange of storage media. These Recommendations I International Standards provide for the interchange of documents for either or both of the following purposes: - - to allow presentation as intended by the originator; to allow processing such as editi

19、ng and reformatting. The composition of a document in interchange can take several forms: formatted form, allowing presentation of the document; processable form, allowing processing of the document; formatted processable form, allowing both presentation and processing. - - - These Recommendations I

20、 International Standards also provide for the interchange of ODA information structures used for the processing of interchanged documents. This ITU-T Recommendation I International Standard defines: the raster graphics content architectures that can be used in conjunction with the document architect

21、ure defined in ITU-T Rec. T.412 I ISO/IEC 8613-2; the internaI structure of content portions that are structured according to a raster graphics content arcbi tecture ; those aspects of positioning and imaging applicable to the presentation of raster graphics contents in a basic layout object; a cont

22、ent layout process which, together with the document layout process defined in ITU-T Rec. T.412 I ISOAEC 8613-2, specifies the method for determining the dimensions of basic layout objects for raster graphics content portions; the presentation and content portion attributes applicable to raster grap

T.411 I IS0 8613-1 apply. 6 General principles 6.1 Content architecture classes This Specification def

35、ines two classes of raster graphics content architectures: - Formatted raster graphics content architecture class, which allows for document content to be presented as intended by the originator. Formatted form content can only be associated with basic layout components. - Formatted processable rast

36、er graphics content architecture class, which allows for document content to be processed and also to be presented as intended by the originator. Formatted processable content can be associated with any basic component. 6.1.1 Formatted content architecture class Formatted raster graphics content is

37、intended to be laid out, or imaged, by the recipient in accordance with the originators intent. It is not intended to be reformatted. This form of content may only be used in formatted form documents. For this form of content all the necessary information for positioning of pels has been specified.

38、The method of positioning is specified in clause 8. A particular feature of this form of content is that the position of the pel may can be offset relative to the position of the basic layout object. As a result, it is possible that not all of the area of the basic layout object is utilized for posi

39、tioning pels. A portion of the pel array may also be positioned such that it is outside the basic layout object. Such a portion, if any, is not imaged. 6.1.2 Formatted processable content architecture class Formatted processable raster graphics content is intended to be laid out, reformatted or imag

40、ed by the recipient in accordance with the originators intent. This form of content may be used in formatted, processable and formatted processable form documents. The originator may, when using this form of content, specify the precise requirements for the layout and imaging of the pel array. Alter

41、natively, the originator may specify various constraints concerning the intended layout and imaging of the pel array, i.e. the precise requirements are not specified and the layout is determined by the content layout process performed by the recipient. When the precise requirements for the layout ar

42、e specified, the fixed dimension layout method is used to layout and image the content. Otherwise, the content is laid out and imaged using the scalable dimension layout method. These layout methods are defined in clause 12. A particular feature of these layout methods is that in both cases the cont

43、ent is laid out such that the entire basic layout object is utilized. In addition it is possible to specify that only a portion of the pel array is to be laid out. ITU-T Rec. T.417 (1993 E) 3 ISO/IEC 8613-7 : 1994 (E) 6.2 Content There are two modes, named binary and colour, for determining the imag

44、e of a pel. Each encoding scheme defined in clause 11 corresponds to just one mode. 6.2.1 Binary mode In the binary mode, the data which determines the image of a pel specifies one of the two states, named set and unser. The set state indicates that the colour specified in the attribute “content for

45、eground colour” applying to the object to which the content is associated is to be used. The unset state indicates that the colour specified in the attribute “content background colour” applying to the object to which the content is associated is to be used. Both attributes are defined in ITU-T Rec.

46、 T.412 I ISO/IEC 8613-2. NOTE - According to ITU-T Rec. T.414 I ISOAEC 8613-4, all of the colour space types RGB, CMY(K), CIELUV, and CIELAB are permitted. 6.2.2 Colour mode In the colour mode, the colour of the image of a pel is specified in the pel encoding. The attribute “content background colou

47、r” applying to the object with which the content is associated is ignored. The attribute “content foreground colour” applying to the object with which the content is associated is used in some encoding schemes to derive the reference to the applying colour space and the colour tolerance specificatio

48、n (see clause 11). NOTE - According to ITU-T Rec. T.414 I ISOAEC 8613-4, all of the colour space types RGB, CMY(K), CIELUV, and CIELAB are permitted. 6.3 Presentation attributes Presentation attributes are applicable to basic components and specify information for laying out and imaging the content

49、of the basic component, and are defined in clause 7. This information cannot be modified within the content of the basic component to which it applies. All raster graphics content presentation attributes are: - - - non-mandatory when specified for presentation styles; non-mandatory when applied to object class descriptions; defaultable when applied to object descriptions. Presentation attributes are
