6 ttfautohintGUI - add new, auto-generated hints to a TrueType font
7
9 ttfautohintGUI [OPTION]...
10
12 A GUI application to replace hints in a TrueType font.
13 The new hints are based on FreeType's auto-hinter.
15 This program is a simple front-end to the `ttfautohint' library.
17 Long options can be given with one or two dashes, and with and without
19 equal sign between option and argument. This means that the following
20 forms are acceptable: `-foo=bar', `--foo=bar', `-foo bar', `--foo bar'.
21 Mandatory arguments to long options are mandatory for short options
23 too. Options not related to Qt or X11 set default values.
24
26 -a, --stem-width-mode=S
27 select stem width mode for grayscale, GDI ClearType, and DW
28 ClearType, where S is a string of three letters with possible
29 values `n' for natural, `q' for quantized, and `s' for strong
30 (default: qsq)
31 -c, --composites
33 hint glyph composites also
34 -d, --dehint
36 remove all hints
37 -D, --default-script=S
39 set default OpenType script (default: latn)
40 -f, --fallback-script=S
42 set fallback script (default: none)
43 -F, --family-suffix=S
45 append suffix to the family name string(s) in the `name' table
46 -G, --hinting-limit=N
48 switch off hinting above this PPEM value (default: 200); value 0
49 means no limit
50 -h, --help
52 display this help and exit
53 -H, --fallback-stem-width=N
55 set fallback stem width (default: 50 font units at 2048 UPEM)
56 --help-all
58 show Qt and X11 specific options also
59 -i, --ignore-restrictions
61 override font license restrictions
62 -I, --detailed-info
64 add detailed ttfautohint info to the version string(s) in the
65 `name' table
66 -l, --hinting-range-min=N
68 the minimum PPEM value for hint sets (default: 8)
69 -n, --no-info
71 don't add ttfautohint info to the version string(s) in the
72 `name' table
73 -p, --adjust-subglyphs
75 handle subglyph adjustments in exotic fonts
76 -r, --hinting-range-max=N
78 the maximum PPEM value for hint sets (default: 50)
79 -s, --symbol
81 input is symbol font
82 -S, --fallback-scaling
84 use fallback scaling, not hinting
85 -t, --ttfa-table
87 add TTFA information table
88 -v, --verbose
90 show progress information
91 -V, --version
93 print version information and exit
94 -W, --windows-compatibility
96 add blue zones for `usWinAscent' and `usWinDescent' to avoid
97 clipping
98 -x, --increase-x-height=N
100 increase x height for sizes in the range 6<=PPEM<=N; value 0
101 switches off this feature (default: 14)
102 -X, --x-height-snapping-exceptions=STRING
104 specify a comma-separated list of x-height snapping exceptions,
105 for example "-9, 13-17, 19" (default: "")
106 Qt Options:
108 --reverse
109 set layout direction to right-to-left
110 --style=STYLE
112 set application GUI style (available values like `windows' or
113 `gtk' depend on Qt version and installed plug-ins)
114 --stylesheet=SHEET
116 apply the given Qt stylesheet to the application widgets
117 The program accepts both TTF and TTC files as input. Use option -i
119 only if you have a legal permission to modify the font. The used PPEM
120 value for option -p is FUnits per em, normally 2048. With option -s,
121 use default values for standard stem width and height, otherwise they
122 are derived from script-specific characters resembling the shape of
123 character `o'.
124 A hint set contains the optimal hinting for a certain PPEM value; the
126 larger the hint set range (as given by options -l and -r), the more
127 hint sets get computed, usually increasing the output font size. The
128 `gasp' table of the output file always enables grayscale hinting for
129 all sizes (limited by option -G, which is handled in the bytecode).
130 Increasing the value of -G does not increase the output font size.
131 Options -f and -D take a four-letter string that identifies a script.
133 Option -f sets the script used as a fallback for glyphs that can't be
134 associated with a known script. By default, such glyphs are hinted; if
135 option -S is set, they are scaled only instead. Option -D sets the de‐
136 fault script for handling OpenType features.
137 Possible four-letter string values are
139 adlm (Adlam), arab (Arabic), armn (Armenian), avst (Avestan),
141 bamu (Bamum), beng (Bengali), buhd (Buhid), cakm (Chakma), cans
