Qt Options:¶

--reverse

set layout direction to right-to-left

--style=STYLE

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

--stylesheet=SHEET

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), 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), hmnp (Nyiakeng Puachue Hmong), 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), medf (Medefaidrin), mong (Mongolian), mymr (Myanmar), nkoo (N'Ko), olck (Ol Chiki), orkh (Old Turkic), osge (Osage), osma (Osmanya), rohg (Hanifi Rohingya), saur (Saurashtra), shaw (Shavian), sinh (Sinhala), sund (Sundanese), taml (Tamil), tavt (Tai Viet), telu (Telugu), tfng (Tifinagh), thai (Thai), vaii (Vai), yezi (Yezidi), none (no script).

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