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


       ttfautohintGUI [OPTION]...


       A GUI application to replace hints in a TrueType font.

       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 not
       related to Qt or X11 set default values.


       -a, --stem-width-mode=S
              select stem width mode for grayscale, GDI ClearType, and DW ClearType, where S is a
              string  of  three  letters with possible values `n' for natural, `q' for quantized,
              and `s' for strong (default: qsq)

       -c, --composites
              hint glyph composites also

       -d, --dehint
              remove all hints

       -D, --default-script=S
              set default OpenType script (default: latn)

       -f, --fallback-script=S
              set fallback script (default: none)

       -F, --family-suffix=S
              append suffix to the family name string(s) in the `name' table

       -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

       -H, --fallback-stem-width=N
              set fallback stem width (default: 50 font units at 2048 UPEM)

              show Qt and X11 specific options also

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

       -I, --detailed-info
              add detailed ttfautohint info to the version string(s) in the `name' table

       -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, --adjust-subglyphs
              handle subglyph adjustments in exotic fonts

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

       -s, --symbol
              input is symbol font

       -S, --fallback-scaling
              use fallback scaling, not hinting

       -t, --ttfa-table
              add TTFA information table

       -v, --verbose
              show progress information

       -V, --version
              print version information and exit

       -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: "")

   Qt Options:
              set layout direction to right-to-left

              set application GUI style (available values like `windows' or `gtk'  depend  on  Qt
              version and installed plug-ins)

              apply the given Qt stylesheet to the application widgets

       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 (as given by options -l and -r), the more hint sets get computed, usually increasing
       the  output  font  size.   The  `gasp'  table  of the output file always enables grayscale
       hinting for all  sizes  (limited  by  option  -G,  which  is  handled  in  the  bytecode).
       Increasing the value of -G does not increase the output font size.

       Options  -f and -D take a four-letter string that identifies a script.  Option -f sets the
       script used as a fallback for glyphs that can't be associated with  a  known  script.   By
       default,  such  glyphs  are  hinted;  if  option  -S is set, they are scaled only instead.
       Option -D sets the default script for handling OpenType features.

       Possible four-letter string values are

              adlm (Adlam), arab (Arabic), armn (Armenian), avst (Avestan),  bamu  (Bamum),  beng
              (Bengali),  buhd  (Buhid), cakm (Chakma), cans (Canadian Syllabics), cari (Carian),

              dsrt  (Deseret),  ethi  (Ethiopic),  geor  (Georgian  (Mkhedruli)),  geok (Georgian
              (Khutsuri)), glag (Glagolitic), goth (Gothic), grek (Greek), gujr (Gujarati),  guru
              (Gurmukhi),  hebr  (Hebrew),  kali  (Kayah Li), khmr (Khmer), khms (Khmer Symbols),
              knda (Kannada), lao (Lao), latn (Latin),  latb  (Latin  Subscript  Fallback),  latp
              (Latin  Superscript  Fallback), lisu (Lisu), mlym (Malayalam), mymr (Myanmar), nkoo
