TTFAUTOHINTGUI(1)

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

SYNOPSIS
ttfautohintGUI [OPTION]...

DESCRIPTION
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.

OPTIONS

-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)

--help-all
    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:

--graphicssystem=SYSTEM
    select a different graphics system backend instead of the default one (possible values: `raster', `opengl')

--reverse
    set layout direction to right-to-left

--session=ID
    restore the application for the given ID

--style=STYLE
    set application GUI style (possible values: motif, windows, platinum)

--stylesheet=SHEET
    apply the given Qt stylesheet to the application widgets

  X11 options:

--background=COLOR
    set the default background color and an application palette (light and dark shades are calculated)

--bg=COLOR
    same as --background

--btn=COLOR
    set the default button color

--button=COLOR
    same as --btn

--cmap
    use a private color map on an 8-bit display

--display=NAME
    use the given X-server display

--fg=COLOR
    set the default foreground color

--fn=FONTNAME
    set the application font

--font=FONTNAME
    same as --fn

--foreground=COLOR
    same as --fg

--geometry=GEOMETRY
    set the client geometry of first window

--im=SERVER
    set the X Input Method (XIM) server

--inputstyle=STYLE
    set X Input Method input style (possible values: onthespot, overthespot, offthespot, root)

--name=NAME
    set the application name

--ncols=COUNT
    limit the number of colors allocated in the color cube on an 8-bit display, if the application is using the QApplication::ManyColor color specification

--title=TITLE
    set the application title (caption)

--visual=VISUAL
    force the application to use the given visual on an 8-bit display (only possible value: TrueColor)

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), cher (Cherokee), copt (Coptic), cprt (Cypriot), cyrl (Cyrillic), deva (Devanagari), 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 (N'Ko), olck (Ol Chiki), orkh (Old Turkic), osge (Osage), osma (Osmanya), saur (Saurashtra), shaw (Shavian), sinh (Sinhala), sund (Sundanese), taml (Tamil), tavt (Tai Viet), telu (Telugu), tfng (Tifinagh), thai (Thai), vaii (Vai), none (no script).

A command-line version of this program is called `ttfautohint'.
