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 met-
rics 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 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 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 deci-
mal 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.
