Rust PBF Font Tools

This crate contains tools for working with SDF font glyphs in PBF format for use in renderers like Mapbox GL.

Features

• Combine multiple glyphs from multiple fonts into a single stack.
• Generate glyphs from a TrueType/OpenType font.

If you're looking for a CLI tool to generate PBF ranges en masse like node-fontnik), but faster, check out build_pbf_glyphs.

NOTE: This has been developed and tested against FreeType 2.10. It will work against older versions, but the glyph generation tests may not pass as the rendering evolves over time.
