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 met-
       rics) 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 exam-
       ple, the AMFM file is MyriadMM.amfm and the AFM files are MyriadMM-LightCn.afm, MyriadMM-LightSemiEx.afm, MyriadMM-BlackCn.afm,	and  Myri-
       adMM-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  sup-
       ply  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  file-
       name, 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 num-
	    bers 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.
