XREMARKS:  XThe attribute "spacing ratio" one has an effect when the value of the parameter "aspect ratio flag" in the attribute "image dimensions" is set to 'fixed'. 6.4XContent architecture class attributes 6.4.1XContent architecture class  XThe value of the attribute "content architecture class" of a basic component description that conforms to this Recommendation is an ASN.1 object identifier with one of the following values: X{28270} for the formatted content architecture class; X{28272} for the formatted processable content architecture class. 6.4.2XContent type  XThe formatted content architecture class can be specified by the attribute "content type" with the value 1.  XNote Use of the attribute "content type" as an alternative to use of the content architec ture class attribute "content architecture class" is permitted only for compatibility with Recommendation T.73 (1984). 7 X Definition of raster graphics content portion attributes  XAccording to Recommendation T.412, content portion attributes consist of four categories: X identification attributes; X common coding attributes; X coding attributes; X content information attributes. XThe identification attributes are completely defined in Recommendation T.412.  XThe common coding attributes are described in Recommendation T.412; attribute values that are specific to raster graphics content architectures are specified in 7.1.  XCoding attributes are defined in 7.2 and the format of the content information, i.e. the possible values of content information attributes, is specified in 7.3. 7.1XCommon coding attributes 7.1.1X type of coding XCLASSIFICATION: Defaultable  XAPPLICABILITY: "Formatted and formatted processable content architecture class XSTRUCTURE:p ASN.1 object identifier or nonnegative integer >0 Xp $%%p&Xp $%%p&XPERMISSIBLE VALUES: ASN.1 object identifier: X p {28370} for 'Rec.

XThe value of the attribute "type of coding" of a content portion description, that conforms to this Recommendation, is an ASN.1 object identifier or an integer. XREMARKS:  XFor bitmap encoding, the relationship between the order of the pels and the order of the bits within an octet is such that the first pel in the order of bits is allocated to the most significant bit of an octet. 7.2XCoding attributes  XThese attributes provide information required for encoding and decoding the content information, as well as other information that is intrinsic to the content portion and required by the content layout and imaging processes. 7.2.1X compression XCLASSIFICATION: Defaultable  XAPPLICABILITY: "Formatted and formatted processable content architecture class XPERMISSIBLE VALUES: 'Compressed', 'uncompressed' XDEFAULT VALUE: "'Compressed' XDEFINITION:  XThis attribute indicates if the code extension technique for uncompressed mode is present in the content portion. This attribute can have one of two values:  X 'compressed' indicates that the code extension technique for uncompressed mode is not used.;'  X 'uncompressed' indicates that the code extension technique for uncompressed mode may be used.'  XNote Basic mode (compressed) encoding is used initially for coding all such content portions. The occurrence of the code extension technique for uncompressed mode coding results in subsequent content being coded in uncompressed mode.

XThese data types are:  X the data type to represent raster graphics content architecture specific presentation attributes in basic layout components, presentation styles and default value lists;'  X the data type to represent raster graphics content architecture specific coding attributes in content portions;'  X the data type to represent nonbasic values of raster graphics content architecture presentation attributes in the document profile;'  X the data type to represent nonbasic values of raster graphics content architecture coding attributes in the document profile;'  X the data type to represent nonstandard default values of raster graphics content architecture presentation and coding attributes in the document profile.' 8.2XRepresentation of presentation attributes  XThe data type "RasterGraphicsAttributes" contains a set of subordinate data types that specify the raster graphics presentation attributes. Some of these subordinate data types are elementary but others are structured and are themselves made up of subordinate data types. The format of these data types is given below.  XThe subset of subordinate data types that may occur within a particular instance of the data type "RasterGraphicsAttributes" depends upon the particular raster graphics content architecture level that is specified.
