PixelFont

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

“PixelFont” implements a subset of the OpenType specification, purely in Elixir 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.

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!)
