This file accompanied the original distribution of the Hershey fonts,
|
|
via the Usenet:
|
|
|
|
***************************************************************************
|
|
|
|
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 distribution:
|
|
- contains
|
|
* a complete copy of the Font data using the original
|
|
glyph-numbering sequence
|
|
* a set of translation tables that could be used to generate
|
|
ASCII-sequence fonts in various typestyles
|
|
* a couple of sample programs in C and Fortran that are
|
|
capable of parsing the font data and displaying it
|
|
on a graphic device (we recommend that if you
|
|
wish to write programs using the fonts, you should
|
|
hack up one of these until it works on your system)
|
|
|
|
- consists of the following files...
|
|
hershey.doc - details of the font data format, typestyles and
|
|
symbols included, etc.
|
|
hersh.oc[1-4] - The Occidental font data (these files can
|
|
be catenated into one large database)
|
|
hersh.or[1-4] - The Oriental font data (likewise here)
|
|
*.hmp - Occidental font map files. Each file is a translation
|
|
table from Hershey glyph numbers to ASCII
|
|
sequence for a particular typestyle.
|
|
hershey.f77 - A fortran program that reads and displays all
|
|
of the glyphs in a Hershey font file.
|
|
hershey.c - The same, in C, using GKS, for MS-DOS and the
|
|
PC-Color Graphics Adaptor.
|
|
|
|
Additional Work To Be Done (volunteers welcome!):
|
|
|
|
- Integrate this complete set of data with the hershey font typesetting
|
|
program recently distributed to mod.sources
|
|
- Come up with an integrated data structure and supporting routines
|
|
that make use of the ASCII translation tables
|
|
- Digitize additional characters for the few places where non-ideal
|
|
symbol substitutions were made in the ASCII translation tables.
|
|
- Make a version of the demo program (hershey.c or hershey.f77) that
|
|
uses the standard Un*x plot routines.
|
|
- Write a banner-style program using Hershey Fonts for input and
|
|
non-graphic terminals or printers for output.
|
|
- Anything else you'd like!
