Project to create a COLR/CPAL-based color OpenType font from the EmojiOne collection of emoji images.
Note that the resulting font will only be useful on systems that support layered color TrueType fonts; this includes Windows 8.1 and later, as well as Mozilla Firefox and other Gecko-based applications running on any platform.
Systems that do not support such color fonts will show blank glyphs if they try to use this font.
This project makes use of grunt-webfont and an additional node.js script. Therefore, installation of Node.js (and its package manager npm) is a prerequisite. Grunt will be installed as a package dependency — no need to install it globally.
The necessary tools can be installed via npm:
# install dependencies from packages.json, including `grunt-webfont`. npm install
Both FontForge and font-tools can be installed via
homebrew on OS X, or package managers on Linux:
# OS X brew install fonttools fontforge # Ubuntu, for example sudo apt-get install fonttools fontforge
Building the font
Once the necessary build tools are all in place, simply running
should build the color-emoji font
build/EmojiOne Mozilla.ttf from the source SVG files found in
e1-svg.zip file and
