Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies

(ISO member bodies). The work of preparing International Standards is normally carried out through ISO

technical committees. Each member body interested in a subject for which a technical committee has been

established has the right to be represented on that committee. International organizations, governmental and

non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the

International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards

adopted by the technical committees are circulated to the member bodies for voting. Publication as an

International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. ISO shall not be held responsible for identifying any or all such patent rights.

Amendment 1 to ISO 12639:2004 was prepared by Technical Committee ISO/TC 130, Graphic technology.

Annex L
(informative)
Incorporating JBIG2-Amd2 compressed data into TIFF/IT
L.1 Incorporating JBIG2-Amd2 compressed data into TIFF/IT

This annex defines JBIG2-Amd2 compressed data that may be included in TIFF/IT-BP and TIFF/IT-SD

images or files. The images described in this annex belong to TIFF/IT-BP or TIFF/IT-SD image types.

JBIG2-Amd2 compression may be used in TIFF/IT-BP and TIFF/IT-SD.

JBIG2-Amd2 compression shall not be used in TIFF/IT-BP/P1, -BP/P2, -SD/P1 or -SD/P2. JBIG2-Amd2

compression shall not be used in TIFF/IT-CT, -LW, -HC, -MP or -BL.

Unless other specifications are indicated in this annex, the compliant file, reader and writer for TIFF/IT-BP or

TIFF/IT-SD with JBIG2-Amd2 compressed data shall accept the conforming level for TIFF/IT-BP or TIFF/IT-

SD respectively.

In specifications of TIFF/IT-BP and TIFF/IT-SD for the JBIG2-Amd2 compressed data, classification marks

and values of TIFF/IT fields basically conform to those of TIFF/IT-BP or TIFF/IT-SD images or files (see

Tables 12 and 14).
L.2 Requirement for incorporating JBIG2-Amd2 compressed data into TIFF/IT-BP or
TIFF/IT-SD
L.2.1 General

JBIG2-Amd2 compressed data in this annex are based on Amendment 2 to JBIG2 (JBIG2-Amd2), described

in ISO/IEC 14492:2001/Amd.2:2003, which is a common text with ITU-T Rec. T.88/Amd.2. JBIG2-Amd2 may

be based on sequential coding of the image pixels using arithmetic coding, which is specified in Annex E of

ISO/IEC 14492:2001, which is a common text with ITU-T Rec. T.88, and a template to determine the coding

state. This technique was used in ISO/IEC 11544 (JBIG), which is a common text with ITU-T Rec. T.82.

JBIG2-Amd2 provides effective lossless compression for bi-level images, like the halftones used in printing.

A TIFF/IT-BP or TIFF/IT-SD image or file with the JBIG2-Amd2 compressed data shall have Compression

field with the value of 34715.
259 Compression SHORT = 34715

TIFF/IT JBIG2-Amd2 compression procedure may be applied to TIFF/IT-BP and TIFF/IT-SD images. TIFF/IT

JBIG2-Amd2 compression procedure shall not be applied to TIFF/IT images with the other compressed data.

NOTE JBIG2-Amd2 (ISO/IEC 14492:2001/Amd.2:2003, which is a common text with ITU-T Rec. T.88/Amd.2) was

developed by ISO/IEC JTC 1/SC 29/WG 1 and published in 2003.

L.2.2 Usage of JBIG2-Amd2 compressed codestream for TIFF/IT-BP

In a TIFF/IT-BP file with the JBIG2-Amd2 compressed data, the TIFF/IT tag fields that are related to the

JBIG2-Amd2 compressed data strip are StripOffsets and StripByteCounts (see Table 12). The counts of

StripOffsets and StripByteCounts shall be 1. Other tag fields are not related to the descriptions of compressed

strip format, and specify information related to the original (or uncompressed) TIFF/IT file format or image

types to be reconstructed from the compressed image.

A JBIG2-Amd2 compressed codestream for TIFF/IT-BP in this annex has the following restrictions.

NOTE The term “Codestream” in this annex corresponds to “compressed strip data”.

a) A JBIG2-Amd2 compressed codestream contains four types of segments; profiles segment, page-

information segment, immediate-lossless-generic-region segment, and end-of-page segment.

b) A JBIG2-Amd2 compressed codestream consists of at least five segments; a profiles segment, a page-

information segment, at least two immediate-lossless-generic-region segments, and an end-of-page

segment as shown in Figure L.1.

c) The referred-to-segment-count-and-retention-flags of the segment-headers of all segments shall be 0.

d) All segments have no referred-to-segment number fields in their segment-headers.

e) The segment-page-association in the segment-headers of all segments, except the profiles segment,

shall be 1.

f) The region-segment-bitmap-X-location in the all region-segment-information-fields shall be 0.

g) The first segment in the codestream shall be a profiles segment.
1) The segment-header-flags is 0x34.
2) The segment-page-association in the segment-header shall be 0.
3) The profiles-segment-data-part contains only one profile of 0x00000008.
h) The second segment shall be a page-information segment.
1) The segment-header-flags is 0x30.

2) A value contained in a page-bitmap-width field in the page-information segment shall be the smallest
