# PixelFont

[![GitHub Workflow Status](https://github.com/Dalgona/pixel_font/actions/workflows/run_tests.yml/badge.svg)](https://github.com/Dalgona/pixel_font/actions/workflows/run_tests.yml) [![Coverage Status](https://coveralls.io/repos/github/Dalgona/pixel_font/badge.svg?branch=main)](https://coveralls.io/github/Dalgona/pixel_font?branch=main)

"PixelFont" is an all-in-one tool for creating TrueType outline fonts from bitmap glyph data.

"PixelFont" implements a subset of the [OpenType specification](https://docs.microsoft.com/en-us/typography/opentype/spec/), purely in [Elixir](https://elixir-lang.org) programming language.

## Features

- Builds full-featured font files which can be used in serious places.

- Generates optimal pixelated TrueType outlines based on 1bpp bitmap images.

- Supports creating fonts with OpenType advanced typographic features, namely GPOS and GSUB.

- Provides DSL and data structures for defining...

  - Font metadata,

  - TrueType outline glyphs based on bitmap image,

  - Composite glyphs (maximum depth of 1 for now),

  - And a subset of GPOS and GSUB lookups.

If you are in doubt, see [The NeoDunggeunmo Project](https://github.com/Dalgona/neodgm).

## Future Goals

- Write some documentations and tests.

- Implement more GPOS and GSUB lookup subtables.

- Wrap all the struct craziness with Elixir DSL. Specifically, provide user experience somewhat similar to using GUI-based font development software... via Elixir DSL. (Good luck!)
