The SignWriting 2010 Fonts


Version 2.0.1
September 13th, 2016

SignWriting 2010 is a typeface for written sign languages which makes the entire International SignWriting Alphabet 2010 symbol set available in TrueType fonts.

The Sutton SignWriting fonts are an updates revision of the SignWriting 2010 fonts which fixes the appearance and size for some of the symbols. The fonts are built with the SignWriting 2010 Tools. The Sutton SignWriting Fonts are used in the Sutton SignWriting Project.

TrueType Fonts

The Sutton SignWriting fonts are fully functional and production ready.

  • Sutton SignWriting - the positive space of the symbol glyphs on plane 4
  • Sutton SignWriting Fill - the negative space of the symbol glyphs on plane 16

Installation

The TrueType Fonts can be installed on Linux, Windows, Mac, and iOS.

Fonts packaged for iOS: SignWriting 2010 Configuration Profile

CSS Font-Face

The CSS Font-Face declaration works with all systems, regardless if the fonts are installed or not. Use the CSS below with any HTML page to access the TrueType fonts.

When the TrueType fonts are not installed, the CSS Font-Face declaration will cause the browser to automatically download and install the fonts in the browser cache. The fonts are about 10 MB combined so the first page view will experience a slight delay while the fonts are downloaded and installed. All subsequent page views, regardless of domain, will use the fonts that have already been installed in the browser cache without any additional delay.

When the TrueType fonts are installed on a system, the CSS Font-Face declaration will cause the browser to use the already installed local fonts and will not download the fonts from the URL. When the fonts are installed, the CSS Font-Face isn't required but neither will it negatively affect performance.

@font-face {
  font-family: "SuttonSignWriting";
  src: 
    local('SuttonSignWriting'),
    url('https://cdn.rawgit.com/Slevinski/signwriting_2010_fonts/master/fonts/SuttonSignWriting.ttf') format('truetype');
}
@font-face {
  font-family: "SuttonSignWritingFill";
  src: 
    local('SuttonSignWritingFill'),
    url('https://cdn.rawgit.com/Slevinski/signwriting_2010_fonts/master/fonts/SuttonSignWritingFill.ttf') format('truetype');
}

Source SVG

The source SVG required to build the TrueType fonts is available in 2 data files. These files were created with the SignWriting 2010 Tools by retracing the SVG Refinement. These files can be unpacked with the SignWriting 2010 Tools. Each symbol has an explicit size listed in the symsize.txt file.


Historical Formats

The original font was created by Valerie Sutton as individual PNG files. The SVG Refinement was a partnership of hand crafted SVGs by Adam Frost with automation tools by Stephen E Slevinski Jr.

These files can be unpacked with the SignWriting 2010 Tools.
