Foreword
IS0 (the International Organization for Standardization) and IEC (the Inter-
national Electrotechnical Commission) form the specialized system for worldwide
standardization. National bodies that are members of IS0 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.
IS0 and IEC technical committees collaborate in fields of mutual interest. Other
international organizations, governmental and non-governmental, in liaison with
IS0 and IEC, also take part in the work.
In the field of information technology, IS0 and IEC have established a joint
technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the
joint technical committee are circulated to national bodies for voting. Publication
as an International Standard requires approval by at least 75 % of the national
bodies casting a vote.
Amendment 2 to International Standard ISOLEC 8632- 1 : 1992 was prepared by
Joint Technical Committee ISOLEC JTC 1, Information technology,
Subcommittee SC 24, Computer graphics and image processing.

O Introduction
Subclause 0.9 Versions, page xiii:
Change the 4th sentence to read:
"The following versions are currently defined: Version 1 (one); Version 2 (two); Version 3 (three);
Version 4 (four)."
Change Note 1 by adding a sentence before the 1st sentence:
"A valid Version 3 metafile is also a valid Version 4 metafile."
Change Note 2 by adding a sentence @ter the finul period:
"Version 4 metafiies are defined by ISO/iEC 8632: 1992/Amd.2."
1 Scope
Clause 1, Page 1 :
Replace the 2ndsentence of the lstparagraph to read:
"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 capabilities and design, and meaningful to application constituencies."
Replace the 2nd sentence of the 2ndparagraph to read:
"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 graphic content,
and that provide access to non-standard device capabilities."
Replace the 3rdparagraph with:
"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."
3 Definitions
Subclause 3.1, page 9:
Add the following definition:
"3.1.105 application structure: A sequence of metafile elements delimited by the BEGIN
APPLICATION STRUCTURE and END APPLICATION STRUCTURE elements, containing
