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. The new hints are based on FreeType's autohinter. 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¶

-f, --latin-fallback

set fallback script to latin

-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

-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

The program accepts both TTF and TTC files as input. Use option -i only if you have a legal permission to modify the font. If option -f is not set, glyphs not in the latin range stay unhinted. 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 latin 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). A GUI version of this program is called `ttfautohintGUI'.
