ttf2mesh   Build Status Latest Version Docs Version

A high-level Rust wrapper API for fetisov's ttf2mesh library for generating a 2d/3d mesh (vertices, indices and normals [only for 3D]) from TrueType (.ttf) glyphs.

Installing

Prequisites:

apt-get install build-essential patch

Add to Cargo.toml:

[dependencies]
ttf2mesh = "*" # change to latest version

Examples

See examples -folder and crate docs.

Simple usage:

use ttf2mesh::{Quality, TTFFile, Value};

let mut font = TTFFile::from_file("fonts/FiraMono-Medium.ttf").unwrap();

for char in "Hello_World".chars() {
    let mut glyph = font.glyph_from_char(char).unwrap();
    let mesh = glyph.to_2d_mesh(Quality::Medium).unwrap();

    println!("Mesh data char {:?}", char);
    println!(
        "- vertices: [{}]",
        mesh.iter_vertices()
            .map(|v| {
                let v = v.val();
                format!("({:.3}, {:.2})", v.0, v.1)
            })
            .collect::<Vec<_>>()
            .join(", ")
    );
    println!(
        "- faces: [{}]",
        mesh.iter_faces()
            .map(|v| {
                let v = v.val();
                format!("({}, {}, {})", v.0, v.1, v.2)
            })
            .collect::<Vec<_>>()
            .join(", ")
    );
    println!("");
}
