PROGRAM SYMGEN
C------------------------------------------------------------------------
C
C Interactive program for creating and modifying vector fonts.
C
C
C A font set is kept stored in a database file XXXX.FNT, which
C is read in when the program is invoked with
C
C % symgen XXXX
C
C The first line of XXXX.FNT is a list of the defined characters.
C Each subsequent line then defines one character in the list:
C
C ABCD...
C 21616 12168 13280 ... <- definition for "A"
C 21616 12280 14880 ... <- definition for "B"
C .
C .
C
C Each 5-digit number defines a vector node x,y location on a 96x96
C grid, with 16,16 being the lower-left "origin" of the character.
C See SUBR. SYMPLT header below for the encoding format.
C If the numbers are zero or missing, then the font character
C is not plotted (blank).
C
C Once the database has been edited, command "W" will generate
C a Fortran INCLUDE file XXXX.INC, with the vector font information
C placed in DATA statements. This is for use in a SYMBOL-type
C routine to allow plotting of the font. Four sample databases,
C include files, and routines already exist:
C
C CHAR.FNT CHAR.INC SUBR. PLCHAR (Upper,lower case letters)
C SLAN.FNT SLAN.INC SUBR. PLSLAN (Slanted version of CHAR )
C MATH.FNT MATH.INC SUBR. PLMATH (Latex-like Greek symbols)
C SYMB.FNT SYMB.INC SUBR. PLSYMB (Versatec plotting symbols)
C
C also available: SUBR. PLNUMB (Whole floating-point numbers)
C
C SUBR. PLCHAR, PLSLAN, and PLMATH (in ../plt_font.f) are identical
C except for their INCLUDE statements. One can generate analogous
C files and plot routines for any custom font, e.g.
C
C USER.FNT USER.INC SUBR. PLUSER
C
C
C SUBR. PLSYMB is nearly the same, except that it takes an integer
C argument ISYM = 0,1... to select the symbol defined on line ISYM+1:
C
C ABCD...
C 21616 12168 13280 ... <- definition for ISYM = 0
C 21616 12280 14880 ... <- definition for ISYM = 1
C .
C .
C The ASCII characters on the first line are ignored in PLSYMB.
C
C PLSYMB also shifts the symbol down and left by 1/2 the symbol
C size, so the symbol is centered on 0,0. This duplicates the
C Versatec SYMBOL routine. Note that PLSYMB can only plot one
C symbol at a time.
