Subject: Re: Diacritics, orthography, type design, font format
I have delved some more into PostScript's specifications for kerning
and composing, and would like to share the things I have found,
continuing the thread which Charles Bigelow had started in [Linguist
List, Vol. 2, No. 0295] from Mon, 10 Jun 91 22:16:36 PDT.
1/ The basic rendering mechanism takes a character, abbreviated c ,
and performs the following transformation:
 c --> code(c) --> name(c) --> glyph(c) (1)
 code(c) is the character code value for c ;
 name(c) is the PostScript name (from the Encoding dictionary);
 glyph(c) is the rendering of c (from the CharStrings dictionary).
2/ The Adobe Font Metric (AFM) file for each font specifies kerning and
composite font information so that, for a given set of characters (two
characters in this example), we get:
 c1 c2 --> ... ? ... --> kerned_glyph(c1,c2) (2)
 c1 c2 --> ... ? ... --> composite_glyph(c1,c2) (3)
through some internal [?] transformation, where:
 kerned_glyph(c1,c2) "kerns" c1 and c2 ;
 composite_glyph(c1,c2) "composes" c1 and c2 .
It turns out that relative positions in x- and y-directions can be
specified in both kerning and composing, according to the AFM 3.0 specs.
Relative sizes may *not* be specified, however.
3/ Finally -- this is the crucial point why character encoding in
precomposed or separable architectures really does *depend* on
rendering technology, but does *not* matter for PostScript -- the AFM
file allows ligatures to be specified, so that:
 c1 c2 --> ... ? ... --> ligature_name(c1,c2) (4)
and thus can be fed into the latter part of formula (1). This
methodology allows for high fidelity in rendering, especially when
relative positioning of the components is inadequate.
I hope that the above does not contain any glaring error(s), because it
is based only on a reading of PostScript documentation, and not on any
real implementation. I would, therefore, really appreciate any
correction(s) and/or clarification(s) to this posting.

14. Pidgins and creoles
15. The history of linguistics
16. Methodology (data collection, corpora gathering and processing,
 experimentation, etc.)
17. Other (language and women, sign language, etc.)
The Program Committee hopes that linguists of all theoretical persuasions
and in all branches of the discipline will participate. If the sections do
not include a title which accomodates the subject you would like to
present, please send your abstract nevertheless, indicating section 17.
Conference papers may take the form of oral presentations or poster
sessions. Oral presentations and discussion are scheduled to last
thirty minutes. Each poster session will last two hours. The schedule
of papers will be announced in the third circular.
Participants wishing to present a paper are requested to send an
abstract before October 1, 1991. Abstracts (maximum one page,
i.e. 400 words) should conform to following specifications:
- Proposals should be submitted on a 8 1/2 x 11" (21.6 x
 27.9 cm) or A4 typewritten single-spaced page;
- An electric typewriter or good quality printer with black
 ribbon should be used;
- Any special character that cannot be typed or printed
 should be inserted in black ink;
- Five copies are required;
- Abstracts should contain:
. title and section for which the paper is intended;
. name of author;
. a clear and explicit statement of the theory or hypothesis
 to be examined;
. an indication of the main arguments or studies involved,
 including key examples, if applicable;
. a statement of conclusions reached and an assessment of
 their significance.
Abstracts which, on account of their subject matter, cannot
conform to above requirements must contain a clear statement
of the subject to be discussed, its relationship to previous
studies in the same discipline, and its general relevance.
If the material is more appropriate for poster display than
oral presentation, please indicate this both in the abstract
and on the Abstract submission form (form # 2). However, the
final decision concerning the type of presentation will be
made by the Program Committee.
Furthermore, participants are asked to provide a condensed version
of their abstract in photo-ready copy within the frame on the middle
page of this circular. It is this version which will be included in
the abstracts to be distributed to congress participants.
