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.
