EmojiOne font in COLR/CPAL layered format
JavaScript CSS Makefile HTML Python



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.

Getting started

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

The build process also requires fontforge and the TTX script from the font-tools package to be installed, and assumes standard Perl and Python are available.

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 extras, overrides directories.
