# Noto Emoji
|
|
Color and Black-and-White Noto emoji fonts, and tools for working with them.
|
|
|
|
## Building NotoColorEmoji
|
|
|
|
Building NotoColorEmoji currently requires a Python 2.x wide build. To build
|
|
the emoji font you will require a few files from nototools. Clone a copy from
|
|
https://github.com/googlei18n/nototools and either put it in your PYTHONPATH or
|
|
use 'python setup.py develop' ('install' currently won't fully install all the
|
|
data used by nototools). You will also need fontTools, get it from
|
|
https://github.com/behdad/fonttools.git.
|
|
|
|
Then run make. NotoColorEmoji is the default target. It's suggested to use -j,
|
|
especially if you are using zopflipng for compression. Intermediate products
|
|
(compressed image files, for example) will be put into a build subdirectory; the
|
|
font will be at the top level.
|
|
|
|
## Using NotoColorEmoji
|
|
|
|
NotoColorEmoji uses the CBDT/CBLC color font format, which is supported by Android
|
|
and Chrome/Chromium OS, but not macOS. Windows supports it starting with Windows 10
|
|
Anniversary Update. No Browser on macOS supports it, but Edge (on latest Windows)
|
|
does. Chrome on Linux will support it with some fontconfig tweaking, see
|
|
[issue #36](https://github.com/googlei18n/noto-emoji/issues/36). Currently we do
|
|
not build other color font formats.
|
|
|
|
## Color emoji assets
|
|
|
|
The assets provided in the repo are all those used to build the NotoColorEmoji
|
|
font. Note however that NotoColorEmoji often uses the same assets to represent
|
|
different character sequences-- notably, most gender-neutral characters or
|
|
sequences are represented using assets named after one of the gendered
|
|
sequences. This means that some sequences appear to be missing. Definitions of
|
|
the aliasing used appear in the emoji_aliases.txt file.
|
|
|
|
Also note that the images in the font might differ from the original assets. In
|
|
particular the flag images in the font are PNG images to which transforms have
|
|
been applied to standardize the size and generate the wave and border shadow. We
|
|
do not have SVG versions that reflect these transforms.
|
|
|
|
## B/W emoji font
|
|
|
|
The black-and-white emoji font is not under active development. Its repertoire of
|
|
emoji is now several years old, and the design does not reflect the current color
|
|
emoji design. Currently we have no plans to update this font.
