This directory contains programs and routines for creating,
modifying, and using vector fonts.
PROGRAM SYMGEN is an interactive program for creating or modifying
font description files XXXX.FNT, and is invoked with
% make symgen (requires ../libPlt.a)
% symgen XXXX
The header of symgen.f has a description of the format of
a XXXX.FNT file, although this is of no concern to the user.
SYMGEN can create an include file XXXX.INC which has the
font encoding placed into Fortran DATA statements. XXXX.INC
is then compiled with a Versaplot SYMBOL-type routine which
is used in applications.
Four sample databases, include files, and application routines
already exist. The application routines are in ../plt_font.f:
CHAR.FNT CHAR.INC SUBR. PLCHAR (Upper,lower case letters, WYSIWYG)
SLAN.FNT SLAN.INC SUBR. PLSLAN (Upper,lower case slanted letters)
MATH.FNT MATH.INC SUBR. PLMATH (Latex-like Greek symbols, exponents)
SYMB.FNT SYMB.INC SUBR. PLSYMB (Versaplot plotting symbols)
also available: SUBR. PLNUMB (Whole floating-point numbers)
One can generate analogous files and plot routines for any
custom font, e.g.
USER.FNT USER.INC SUBR. PLUSER
PROGRAM TEST plots the complete CHAR, SLAN, MATH, and SYMB fonts,
and also plots sample character strings for examination.
% make test
% test
