This is the original documentation, which I found with the distribution
of the Hershey font at comp.source.unix/volume5/hersh.tar.Z.
This relates only to the font data, and has nothing to do with any of
the code and program included in the TPHersh package.
------------------------------------------------------------------------------
This distribution is made possible through the collective encouragement
of the Usenet Font Consortium, a mailing list that sprang to life to get
this accomplished and that will now most likely disappear into the mists
of time... Thanks are especially due to Jim Hurt, who provided the packed
font data for the distribution, along with a lot of other help.
This file describes the Hershey Fonts in general, along with a description of
the other files in this distribution and a simple re-distribution restriction.
USE RESTRICTION:
This distribution of the Hershey Fonts may be used by anyone for
any purpose, commercial or otherwise, providing that:
1. The following acknowledgements must be distributed with
the font data:
- The Hershey Fonts were originally created by Dr.
A. V. Hershey while working at the U. S.
National Bureau of Standards.
- The format of the Font data in this distribution
was originally created by
James Hurt
Cognition, Inc.
900 Technology Park Drive
Billerica, MA 01821
(mit-eddie!ci-dandelion!hurt)
2. The font data in this distribution may be converted into
any other format *EXCEPT* the format distributed by
the U.S. NTIS (which organization holds the rights
to the distribution and use of the font data in that
particular format). Not that anybody would really
*want* to use their format... each point is described
in eight bytes as "xxx yyy:", where xxx and yyy are
the coordinate values as ASCII numbers.
*PLEASE* be reassured: The legal implications of NTIS' attempt to control
a particular form of the Hershey Fonts *are* troubling. HOWEVER: We have
been endlessly and repeatedly assured by NTIS that they do not care what
we do with our version of the font data, they do not want to know about it,
they understand that we are distributing this information all over the world,
etc etc etc... but because it isn't in their *exact* distribution format, they
just don't care!!! So go ahead and use the data with a clear conscience! (If
you feel bad about it, take a smaller deduction for something on your taxes
next week...)
The Hershey Fonts:
- are a set of more than 2000 glyph (symbol) descriptions in vector
( <x,y> point-to-point ) format
- can be grouped as almost 20 'occidental' (english, greek,
cyrillic) fonts, 3 or more 'oriental' (Kanji, Hiragana,
and Katakana) fonts, and a few hundred miscellaneous
symbols (mathematical, musical, cartographic, etc etc)
- are suitable for typographic quality output on a vector device
(such as a plotter) when used at an appropriate scale.
- were digitized by Dr. A. V. Hershey while working for the U.S.
Government National Bureau of Standards (NBS).
- are in the public domain, with a few caveats:
- They are available from NTIS (National Technical Info.
Service) in a computer-readable from which is *not*
in the public domain. This format is described in
a hardcopy publication "Tables of Coordinates for
Hershey's Repertory of Occidental Type Fonts and
Graphic Symbols" available from NTIS for less than
$20 US (phone number +1 703 487 4763).
- NTIS does not care about and doesn't want to know about
what happens to Hershey Font data that is not
distributed in their exact format.
- This distribution is not in the NTIS format, and thus is
only subject to the simple restriction described
at the top of this file.
Hard Copy samples of the Hershey Fonts are best obtained by purchasing the
book described above from NTIS. It contains a sample of all of the Occidental
symbols (but none of the Oriental symbols).
-------------------------------------------------------------------------------
This file provides a brief description of the contents of the Occidental
Hershey Font Files. For a complete listing of the fonts in hard copy, order
NBS Special Publication 424, "A contribution to computer typesetting
techniques: Tables of Coordinates for Hershey's Repertory of Occidental
Type Fonts and Graphic Symbols". You can get it from NTIS (phone number is
+1 703 487 4763) for less than twenty dollars US.
Basic Glyph (symbol) data:
hersh.oc1 - numbers 1 to 1199
hersh.oc2 - numbers 1200 to 2499
hersh.oc3 - numbers 2500 to 3199
hersh.oc4 - numbers 3200 to 3999
These four files contain approximately 19 different fonts in
the A-Z alphabet plus greek and cyrillic, along with hundreds of special
symbols, described generically below.
There are also four files of Oriental fonts (hersh.or[1-4]). These
files contain symbols from three Japanese alphabets (Kanji, Hiragana, and
Katakana). It is unknown what other symbols may be contained therein, nor
is it known what order the symbols are in (I don't know Japanese!).

ASCII sequence translation files:
The Hershey glyphs, while in a particular order, are not in an
ASCII sequence. I have provided translation files that give the
sequence of glyph numbers that will most closely approximate the
ASCII printing sequence (from space through ~, with the degree
circle tacked on at the end) for each of the above fonts:
File names are made up of fffffftt.hmp,
where ffffff is the font style, one of:
roman Roman
greek Greek
italic Italic
script Script
cyril Cyrillic (some characters not placed in
the ASCII sequence)
gothgr Gothic German
gothgb Gothic English
gothit Gothic Italian
and tt is the font type, one of:
p Plain (very small, no lower case)
s Simplex (plain, normal size, no serifs)
d Duplex (normal size, no serifs, doubled lines)
c Complex (normal size, serifs, doubled lines)
t Triplex (normal size, serifs, tripled lines)
cs Complex Small (Complex, smaller than normal size)
The three sizes are coded with particular base line (bottom of a capital
letter) and cap line (top of a capital letter) values for 'y':
