|
|
Use this script to customize one or more Input font files.
|
|
Requires TTX/FontTools: <http://sourceforge.net/projects/fonttools/>
|
|
|
|
If INPUT is missing, it will customize all fonts in the Current Working Directory.
|
|
If OUTPUT is missing, it will overwrite the INPUT files.
|
|
|
|
Options:
|
|
-h, --help Print this help text, and exit.
|
|
--lineHeight=<float> A multiplier for the font's built-in line-height.
|
|
--fourStyleFamily Only works when four INPUT files are provided.
|
|
Assigns Regular, Italic, Bold, and Bold Italic names to the
|
|
INPUT fonts in the order provided.
|
|
--suffix=<string> Append a suffix to the font names. Takes a string with no spaces.
|
|
--a=ss Swaps alternate single-story 'a' for the default double-story 'a'
|
|
--g=ss Swaps alternate single-story 'g' for the default double-story 'a'
|
|
--i=serif Swaps one of the alternate 'i' for the default in Sans/Mono
|
|
serifs
|
|
serifs_round
|
|
topserif
|
|
--l=serif Swaps one of the alternate 'l' for the default in Sans/Mono
|
|
serifs
|
|
serifs_round
|
|
topserif
|
|
--zero=slash Swaps the slashed zero for the default dotted zero
|
|
nodot Swaps a dotless zero for the default dotted zero
|
|
--asterisk=height Swaps the mid-height asterisk for the default superscripted asterisk
|
|
--braces=straight Swaps tamer straight-sided braces for the default super-curly braces
|
