NAME

       mmafm - creates AFM font metrics for multiple master fonts

SYNOPSIS

       mmafm [OPTIONS...]  font

DESCRIPTION

       Mmafm  creates AFM font metrics for PostScript multiple master fonts by interpolation. You
       pass it an AMFM file (multiple master font metrics)  and  options  specifying  the  design
       point you want, and it writes the resulting AFM file to the standard output.

       Each  font  argument  is  either  the  filename  of an AFM or AMFM font metrics file, or a
       PostScript font name. If you give a font name, mmafm will look up the actual font  metrics
       file  using the PSRESOURCEPATH environment variable. This colon-separated path is searched
       for `PSres.upr' files, an Adobe method for indexing PostScript resources.

       You  can   also   give   the   name   of   a   multiple   master   font   instance,   like
       `MinionMM_367_400_12_'.   Mmafm will parse the font name and create that instance for you.
       `PSres.upr' files must be set up for this to work.

       Any multiple master font should be distributed with a single AMFM  file  and  several  AFM
       files  (one  for each master). For Myriad, for example, the AMFM file is MyriadMM.amfm and
       the AFM files are  MyriadMM-LightCn.afm,  MyriadMM-LightSemiEx.afm,  MyriadMM-BlackCn.afm,
       and  MyriadMM-BlackSemiEx.afm.  Mmafm needs to find all these files to function. For fonts
       in   the   Adobe   type   library,   you   can   download   the   necessary   files   from
       <http://www.lcdf.org/type>; look for the mm-metrics package.

       You  must  always  supply  the AMFM file (or its font name) on the command line, but mmafm
       will  look  for  any  required  AFM  files  you  don't  supply  yourself.  It  tries   the
       PSRESOURCEPATH  environment  variable,  and  also  looks for files named `FontName.afm' or
       `FontName.AFM' in the directory that contained the AMFM file. (The Myriad filenames  given
       above fit this pattern.)

       Mmafm  supports  fonts  with  intermediate  masters, like Adobe Jenson and Kepler. If your
       PSRESOURCEPATH environment variable is set up, it will handle these  fonts  automatically.
       Otherwise,  you  must  first  run  `mmpfb --amcp-info' on the font outline files to create
       auxiliary AMCP files for these fonts.  Each AMCP file should be in the same  directory  as
       its  corresponding  AMFM  file  and should have the same root filename, but with a `.amcp'
       extension instead of `.amfm'. See mmpfb(1) for more information.

EXAMPLE

       % mmafm --weight=400 --width=600 MyriadMM.amfm > MyriadMM_400_600_.afm

OPTIONS

       Long options may be abbreviated to their unique prefixes.

       --output=file, -o file
            Send output to file instead of standard output.

       --weight=N, -w N
            Set the weight axis to N.

       --width=N, -W N
            Set the width axis to N.

       --optical-size=N, -O N
            Set the optical size axis to N.

       --style=N
            Set the style axis to N.

       --1=N (--2=N, --3=N, --4=N)
            Set the first (second, third, fourth) axis to N.

       --precision=N, -p N
            Round output numbers so they have at most N digits after the decimal  point.  Smaller
            numbers  are  less  precise;  `-p  0'  rounds  all  numbers  to integers. The default
            precision is 3.

       --min-kern=N, -k N
            Only output kerning pairs whose absolute value is N or larger. Smaller minimum  kerns
            make kerning more precise and the output AFM file bigger. The default minimum kern is
            2.0.

TROUBLESHOOTING

       Some programs, such as TeX's fontinst, can choke on  AFM  files  that  include  fractional
       numbers.  Therefore,  if  you  have trouble with an AFM file, try rerunning mmafm with the
       --precision=0 option.

DIAGNOSTICS

       Font requires intermediate master conversion programs
            You haven't yet created an AMCP file for Font.
