NAME

       ttfautohint - add new, auto-generated hints to a TrueType font

SYNOPSIS

       ttfautohint [OPTION]... [IN-FILE [OUT-FILE]]

DESCRIPTION

       Replace  hints  in  TrueType  font  IN-FILE  and write output to OUT-FILE.  If OUT-FILE is
       missing, standard output is used instead; if IN-FILE is missing also, standard  input  and
       output are used.

       The new hints are based on FreeType's auto-hinter.

       This program is a simple front-end to the `ttfautohint' library.

       Long  options can be given with one or two dashes, and with and without equal sign between
       option and argument.  This means that the  following  forms  are  acceptable:  `-foo=bar',
       `--foo=bar', `-foo bar', `--foo bar'.

       Mandatory arguments to long options are mandatory for short options too.

OPTIONS

       --debug
              print debugging information

       -c, --composites
              hint glyph composites also

       -d, --dehint
              remove all hints

       -f, --fallback-script=S
              set fallback script (default: dflt)

       -G, --hinting-limit=N
              switch off hinting above this PPEM value (default: 200); value 0 means no limit

       -h, --help
              display this help and exit

       -i, --ignore-restrictions
              override font license restrictions

       -l, --hinting-range-min=N
              the minimum PPEM value for hint sets (default: 8)

       -n, --no-info
              don't add ttfautohint info to the version string(s) in the `name' table

       -p, --pre-hinting
              apply original hints in advance

       -r, --hinting-range-max=N
              the maximum PPEM value for hint sets (default: 50)

       -s, --symbol
              input is symbol font

       -v, --verbose
              show progress information

       -V, --version
              print version information and exit

       -w, --strong-stem-width=S
              use  strong  stem  width  routine  for  modes S, where S is a string of up to three
              letters with possible values `g' for grayscale, `G' for GDI ClearType, and `D'  for
              DirectWrite ClearType (default: G)

       -W, --windows-compatibility
              add blue zones for `usWinAscent' and `usWinDescent' to avoid clipping

       -x, --increase-x-height=N
              increase  x  height  for  sizes  in the range 6<=PPEM<=N; value 0 switches off this
              feature (default: 14)

       -X, --x-height-snapping-exceptions=STRING
              specify a comma-separated list of x-height snapping exceptions,  for  example  "-9,
              13-17, 19" (default: "")

       The  program  accepts  both  TTF and TTC files as input.  Use option -i only if you have a
       legal permission to modify the font.  The used PPEM value for option -p is FUnits per  em,
       normally  2048.   With  option  -s, use default values for standard stem width and height,
       otherwise they are  derived  from  script-specific  characters  resembling  the  shape  of
       character `o'.

       A  hint set contains the optimal hinting for a certain PPEM value; the larger the hint set
       range, the more hint sets get computed, usually increasing the output  font  size.   Note,
       however,  that the `gasp' table of the output file enables grayscale hinting for all sizes
       (limited by option -G, which is handled in the bytecode).

       Option -f takes a four-letter string that identifies the script to be used as  a  fallback
       for glyphs that have character codes outside of known script ranges.  Possible values are

              cyrl (Cyrillic), dflt (no script), grek (Greek), hebr (Hebrew), latn (Latin).

       If no option -f is given, or if its value is `dflt', no fallback script is used.

       A GUI version of this program is called `ttfautohintGUI'.
