This project consists of the following bits and pieces: * A proposed specification to add support for embedded color image glyphs in OpenType fonts, * A tool called emoji_builder.py, to embed a set of PNG images into an existing font, * Two sets of sample PNG images for ASCII characters and sample scripts to build them into test fonts: FruityGirl and Funkster. * Scripts to build a real color emoji font out of the Open Source PhantomOpenEmoji images. Discussions about this work happen at: https://groups.google.com/forum/#!forum/color-emoji Here is the version 1 of the spec: https://rawgit.com/behdad/color-emoji/master/specification/v1.html Here is the announcement: http://google-opensource.blogspot.com/2013/05/open-standard-color-font-fun-for.html Support for this format was included in FreeType in May 2013. Support has also been included in Fontconfig, as well Skia graphics library. A proof-of-concept patchset for the Cairo graphics library to use fallback software rendering for the Xlib backend with support for color glyphs is at https://github.com/behdad/cairo/tree/color-emoji Currently, Android, ChromeOS, Chrome Linux, as well as certain versions of Firefox support rendering fonts built using this format. This format is now part of OpenType specification, version 1.7: http://www.microsoft.com/typography/otspec/cbdt.htm http://www.microsoft.com/typography/otspec/cblc.htm
