# SVGinOT Color Font Builder
*Create color fonts from SVGs on the command line*
`scfbuild` creates *SVG in OpenType* color fonts directly from a set of source
SVG files greatly simplifying the process of creating a custom color font.
Regular color and standard character [glyphs][glyph] are named by
[Unicode][unicode] code point (e.g. `1f60e.svg`). [Ligatures][ligature] are
named by code points separated by a hyphen `-` (e.g.`1f441-1f5e8.svg`). Note:
Color glyphs cannot exist alone, they must replace existing standard glyphs.
The generated fonts work in all operating systems, but will *currently* only
show color glyphs in supported applications. This is not a limitation of the
generated fonts, but of the operating systems and applications. The primary
offender at this time is Chromium, therefore Chrome/NewEdge. [Why doesn't it
work on Chrome?][why-not-chrome]
Only the *SVG in OpenType* color font format is supported. The Apple, Google,
and Microsoft color font formats are not supported at this time.

* [Gradiently][gradiently] - [[source][gradiently-src]]
* [Multicoloure][multicoloure] - [[source][multicoloure-src]]
* [Freizer][freizer] - [[source][freizer-src]]

## What is SVGinOT?
*SVG in Open Type* is a standard by Adobe and Mozilla for color OpenType
and Open Font Format fonts. It allows font creators to embed complete SVG files
within a font enabling full color and even animations. There are more details in
the [SVGinOT proposal][8] and the [OpenType SVG table specifications][9].

## Other Tools
`scfbuild` softens the learning curve for font creation, but cannot replace more
advanced tools. Here are some starting points if you need more features,
although none support color fonts at this time:
