To see a sample of one font on a Datadisk terminal, R DDFONT and give it
the name of the font (e.g. "NGR30"). Say HELP DDFONT for more info.
To print a sample of a particular font on the XGP, say
R FCOPY;<file name>/INFO/SAMPLE. Say HELP FCOPY to learn more of its
To print a sample text on the XGP in a number of different fonts for
comparison, say R FSAMPL.
To make a .TFX file for an existing font (needed if and only if you want
to use this font with the old XGPTEX document compiler), say R TFXGEN.
To edit .TFX files, use TFXPR and TFDRD. Say READ TFX for more info.
To make a .TFM file for an existing font (needed if and only if you want
to use this font with the new TEX document compiler), see TFM.TXT[tex,sys].
To edit .TFM files, use TFTOPL and PLTOTF.
To examine or edit characters in an existing font, use EDFONT, described
To edit the characters of a font using E, use FMUNGE, described in
FMUNGE.REF[UP,DOC] or FNTCHR/CHRFNT, described in FNTCHR.MAI[UP,DOC].
FMUNGE is probably easier to use; FNTCHR/CHRFNT were designed for use
with the METAFONT system.
To create a new font use TVFONT, described in TVFONT.BGB[UP,DOC], or
PIX, described briefly via HELP PIX.
To scale the size of a font use FSCALE, described in FSCALE.DON[UP,DOC].
To combine selected characters from two fonts, use COMBIN (say HELP
COMBIN for description).
To compile a font, RUN UFC[XGP,SYS]. UFC.REG[UP,DOC] explains what
compiling a font means, and why it's good for you.
To poke at all sorts of mystic parameters in a font file (not recommended
unless you know what you're doing!), R FONT. FONT.BH[UP,DOC] is the
documentation file for this program. One warning in particular: Using
FONT to find out the height or width of a few characters (using the
"modify chars" option) will cause the file's last-written date to
change, obsoleting the CFT (compiled font) file for that font. Make a
copy of the file and look at that instead.
To learn about the format of font files, see FORMAT.DOC[XGP,SYS].
Some of the above programs append the ".FNT[XGP,SYS]" if you leave it
out, but all of them (I think) will accept the complete file name if
you type it all.
To create an XGP font using Knuth's Metafont program, see
MANUAL.TEX[MF,DEK]. Hardcopy documentation is available in the TeX and
Metafont manual available from Digital Press, or HELP MF.
