Crate glyphore_core 

Core MapLibre glyph PBF (SDF) generation for glyphore.

Pure logic only: no filesystem access, no clocks, no randomness, no wasm-bindgen. Output follows node-fontnik conventions (24px, 3px buffer, radius 8, cutoff 0.25).

Parse font bytes once with FontFace::parse, inspect the sorted range starts with FontFace::covered_ranges, and pass each start to generate_range.

Example

use glyphore_core::{FontFace, generate_range};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let bytes = std::fs::read("NotoSans-Regular.ttf")?;
    let face = FontFace::parse(&bytes)?;

    for start in face.covered_ranges() {
        let pbf = generate_range(&face, start)?;
        std::fs::write(format!("{start}-{}.pbf", start + 255), pbf)?;
    }
    Ok(())
}
