NAME

6       mftrace - convert METAFONT format fonts into Type1 outline fonts
7

SYNOPSIS

9       mftrace [options] fontname
10

DESCRIPTION

12       mftrace  is  a  program  that  can convert a METAFONT font into a Type1
13       font.  It is simply called with the name of the font (without  a  `.mf'
14       suffix)  and  produces  a Type1 font file called either fontname.pfa or
15       fontname.pfb depending on the command line options.  With the  help  of
16       fontforge(1) it can produce other font formats too.
17
18       For  tracing the bitmap, mftrace either uses potrace(1) or autotrace(1)
19       (the former preferred) if available; this can be  overridden  with  the
20       --autotrace and --potrace command line options.
21

OPTIONS

23       This  program  follows  the  usual  GNU  command line syntax, with long
24       options starting with two dashes (`-').
25
26       -k, --keep
27              Keep all output in directory `mftrace.dir'.
28
29       --magnification=MAG
30              The magnification to use for the PFA file.  The default is 1000.
31              The larger the magnification, the more precise the PFA file will
32              be.  However, if the magnification is  too  large  METAFONT  can
33              crash with overflow errors.
34
35              Sadly, many MF fonts contain resolution checks
36
37                     if dots_per_inch * design_size > 1500:
38
39              This  check is susceptible to overflow errors.  Such code should
40              be reported as a bug, and changed to
41
42                     if dots_per_inch > (1500 / design_size):
43
44       --formats=FMT1,FMT2,...
45              Specify which formats to generate  (default  is  pfa).   Choices
46              are:  `afm',  `pfa',  `pfb',  `ttf', `svg'.  Note that fontforge
47              (formerly called pfaedit) must be installed to generate any for‐
48              mat except `pfa' or `pfb'.  For generating `afm' you need either
49              fontforge or ghostscript.
50
51       --simplify
52              This passes the created Type1 font to fontforge (formerly called
53              pfaedit) to simplify and autohint it.
54
55       --gffile=FILE
56              Use  generic font file FILE instead of running Metafont.  (GF is
57              the default output format of Metafont.)
58
59       -I DIR, --include=DIR
60              Add DIR to the current path for searching files.
61
62       --glyphs=LIST
63              Process only these glyphs.  LIST is a comma  separated  list  of
64              decimal numbers or ranges, for example `1-10,50,55,90-100'.
65
66       --tfmfile=FILE
67              Use   FILE   for   the   TFM  file.   (The  default  is  to  use
68              fontname.tfm).
69
70       -e ENC, --encoding=ENC
71              Use encoding file ENC.  Encoding files used by mftrace are basi‐
72              cally in the GhostScript/dvips format, but you may use a special
73              .notavail glyph name in order to tell mftrace not to  process  a
74              specific  glyph.  If this option is not specified, mftrace tries
75              to determine the encoding file automatically, from the  encoding
76              specified in the TFM file, the default being `tex256.enc'.
77
78       --keep-trying
79              Try to continue if external programs called by mftrace fail.  If
80              METAFONT crashes with overflow errors, but nevertheless  outputs
81              a  GF  file,  try  to  process its output as is (useful for some
82              buggy fonts, see above).  If potrace or autotrace fail to  trace
83              a  specific  character, first try it with a less smoothed curve,
84              and if that fails, skip  the  character.   By  default,  mftrace
85              leaves  a  file  `trace-bug-font-char.pbm' and stops the process
86              with a request to file a bugreport.
87
88       --dos-kpath
89              Try to use MikTeX's version of kpsewhich.
90
91       --potrace
92              Use potrace for tracing bitmaps.  The default is to use  potrace
93              if it is found, otherwise to use autotrace.
94
95       --autotrace
96              Use autotrace for tracing bitmaps.
97
98       --no-afm
99              Don't read the AFM file to find font information.
100
101       --noround
102              Do  not  round  coordinates  of control points to integer values
103              (use with --grid).  Disabled by default.
104
105       --grid=GRID
106              Set reciprocal grid size in em units multiplied by ratio  magni‐
107              fication/1000.   For  example,  `--grid 10 --magnification 1000'
108              rounds coordinates of control points to 1/10th of the  em  unit.
109              Useful  simultaneously  with the --noround option.  Default GRID
110              value is 1, i.e., round to integer.  This option  is  only  used
111              with potrace.
112
113       -D,--define=SYMBOL=VALUE
114              Set  the  font  info  SYMBOL  to  the given VALUE.  For example,
115              -DFamilyName=Foo sets the font  family  name  to  Foo.   mftrace
116              tries  to  fill  in  sensible default values for the `FontName',
117              `FamilyName', `FullName' and `Weight' fields.
118
119       -V, --verbose
120              Be verbose.
121
122       -h, --help
123              Show summary of options.
124
125       -v, --version
126              Show version of program.
127
128       -w, --warranty
129              Show warranty and copyright.
