This CSS3 Font Converter is a shell script that allows developers, using a
command line, to convert a set of TTF and OTF fonts into all the other
currently used CSS3 @font-face formats (i.e. EOT, SVG, WOFF, WOFF2).
Syntax:
convertFonts.sh <filelist>
For example, if you wanted to convert all the .ttf files in the directory you are in, you could type in the command:
$ convertFonts.sh *.ttf
The fonts will then be converted to the .eot, .woff, and .svg formats. It will also generate a stylesheet, stylesheet.css, that will produce the @font-face rules using The New Bulletproof @Font-Face Syntax.
If you are converting .otf fonts, a .ttf font will be generated first before the other fonts.
Usage: /Users/zhawry/bin/convertFonts.sh [-options] [fontfilelist]
Where: - [fontfilelist] is a space separated list of True Type (.ttf) or Open Type (.otf) fonts.
- [-options] are one of the following:
--use-font-weight: This option will merge all font-weights and
styles under the same font name. This option will likely crash
Apple Mobile Safari running under iOS versions less than 4.0.
Also note that only the first four weights and styles
will be recognized under IE7 and 8.
--use-font-stretch: This option will merge all condensed and
expanded fonts under the same font name as the normal font.
It is recommended *not* to use this method currently, since at
the time of this writing, font-stretch is only supported by
Firefox => 9 and IE => 9.
--autohint: This option will hint/re-hint fonts (using ttfautohint
by default, or Adobe Font Development Kit for OpenType if using
the --autohint=adobe option ). Note that this option will create
a bunch of files prefixed with 'hinted-'. Attempting to use this
option on files already prefixed with 'hinted-' will result in an
error.
--use-font-prefix=xxx: This option will prepend the name of all the
fonts with the string xxx. This is useful when you are generating
different stylesheets using the converter with the same font
but with different options.
--output=xxx: This option will produce the resultant @font-face
stylesheet to the file xxx. By default, xxx is set to stylesheet.css
--show-features: Presents the user with a list of OpenType feature
tags a font supports which can be used inside a style sheet using
the CSS3 font-feature-settings property. The font can be in either
be OpenType or TrueType.
--help: This help menu.
