       mftrace - convert METAFONT format fonts into Type1 outline fonts


       mftrace [options] fontname


       mftrace  is  a  program  that can convert a METAFONT font into a Type1 font.  It is simply
       called with the name of the font (without a `.mf' suffix) and produces a Type1  font  file
       called  either  fontname.pfa  or fontname.pfb depending on the command line options.  With
       the help of fontforge(1) it can produce other font formats too.

       For tracing the bitmap,  mftrace  either  uses  potrace(1)  or  autotrace(1)  (the  former
       preferred) if available; this can be overridden with the --autotrace and --potrace command
       line options.


       This program follows the usual GNU command line syntax, with long  options  starting  with
       two dashes (`-').

       -k, --keep
              Keep all output in directory `mftrace.dir'.

              The  magnification  to  use for the PFA file.  The default is 1000.  The larger the
              magnification,  the  more  precise  the  PFA  file  will  be.   However,   if   the
              magnification is too large METAFONT can crash with overflow errors.

              Sadly, many MF fonts contain resolution checks

                     if dots_per_inch * design_size > 1500:

              This  check  is  susceptible to overflow errors.  Such code should be reported as a
              bug, and changed to

                     if dots_per_inch > (1500 / design_size):

              Specify which formats to generate (default is pfa).   Choices  are:  `afm',  `pfa',
              `pfb',  `ttf',  `svg'.   Note  that  fontforge  (formerly  called  pfaedit) must be
              installed to generate any format except `pfa' or `pfb'.  For generating  `afm'  you
              need either fontforge or ghostscript.

              This  passes  the  created  Type1  font  to  fontforge (formerly called pfaedit) to
              simplify and autohint it.

              Use generic font file FILE instead of running Metafont.  (GF is the default  output
              format of Metafont.)

       -I DIR, --include=DIR
              Add DIR to the current path for searching files.

              Process  only  these  glyphs.  LIST is a comma separated list of decimal numbers or
              ranges, for example `1-10,50,55,90-100'.

              Use FILE for the TFM file.  (The default is to use fontname.tfm).

       -e ENC, --encoding=ENC
              Use encoding file ENC.  Encoding  files  used  by  mftrace  are  basically  in  the
              GhostScript/dvips  format,  but you may use a special .notavail glyph name in order
              to tell mftrace not to process a specific glyph.  If this option is not  specified,
              mftrace  tries  to  determine  the  encoding  file automatically, from the encoding
              specified in the TFM file, the default being `tex256.enc'.

              Try to continue if external programs called by mftrace fail.  If  METAFONT  crashes
              with overflow errors, but nevertheless outputs a GF file, try to process its output
              as is (useful for some buggy fonts, see above).  If potrace or  autotrace  fail  to
              trace  a  specific  character, first try it with a less smoothed curve, and if that
              fails,   skip   the   character.    By   default,    mftrace    leaves    a    file
              `trace-bug-font-char.pbm' and stops the process with a request to file a bugreport.

              Try to use MikTeX's version of kpsewhich.

              Use  potrace  for  tracing  bitmaps.  The default is to use potrace if it is found,
              otherwise to use autotrace.

              Use autotrace for tracing bitmaps.

              Don't read the AFM file to find font information.

              Do not round coordinates of control points to integer  values  (use  with  --grid).
              Disabled by default.

              Set  reciprocal  grid size in em units multiplied by ratio magnification/1000.  For
              example, `--grid 10 --magnification 1000' rounds coordinates of control  points  to
              1/10th  of  the em unit.  Useful simultaneously with the --noround option.  Default
              GRID value is 1, i.e., round to integer.  This option is only used with potrace.

              Set the font info SYMBOL to the given VALUE.  For  example,  -DFamilyName=Foo  sets
              the  font family name to Foo.  mftrace tries to fill in sensible default values for
              the `FontName', `FamilyName', `FullName' and `Weight' fields.

       -V, --verbose
              Be verbose.

       -h, --help
              Show summary of options.

       -v, --version
              Show version of program.

       -w, --warranty
              Show warranty and copyright.
