Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO 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. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. 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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
Amendment 1 to ISO/IEC 9541-3:1994 was prepared by Joint Technical Committee ISO/IEC JTC 1,
Information technology, Subcommittee SC 34, Document description and processing languages.
This Amendment specifies an additional shape representation technology and slight modification to
ISO/IEC 9541-3:1994.
The additional interchange format is described by SGML (Standard Generalized Markup Language)
conforming to ISO 8879:1986 and ISO 8879:1986/Cor. 2:1999 (Annex K: Web SGML Adaptations).

Part 3:
Glyph shape representation
AMENDMENT 1: Additional shape representation technology
Page 3
Replace the declaration in subclause 1.7.2 with the following:
Page 45
Add the following Section after Section 2:
Section 3: Type 2 glyph shape representation
3.1 Scope
This section specifies the architecture and interchange format of one standard Glyph Shape Representation:
ISO/IEC 9541 Standard TYPE 2. This representation technique is appropriate for presentation on raster
devices of low resolution or where simple processing or display time is essential, as required for example in
ISO/IEC 10036 registration authority. The representation technique is intended to provide a basic level of
shape definition facilities.

3.2 Definitions
The following definitions are specific to this section.
3.2.1
bitmap
The "picture" of the glyph image represented by a 2-dimensional grid of binary values — 0 (or off) represents
the background (usually, uninked) portion of the glyph image and 1 (or on) represents the foreground (usually
inked) portion of the glyph image.
3.2.2
bounding box
The imaginary box surrounding the bitmap.
NOTE It is equivalent to the imaginary box with lower left coordinates of (minx, miny) and upper right coordinates of
(maxx, maxy) as defined in ISO/IEC 9541-1 rou
