plottery_fonts

65 single-line fonts for pen plotters, laser cutters, CNC engravers and anything else that draws strokes instead of filling shapes. All of them are free to redistribute, the licences and credits ship with the crate.

The crate is pure data with no dependencies: every font is embedded with include_bytes! and exposed through the BundledFont enum. It is made for Plottery, but nothing in it depends on Plottery.

Usage with Plottery

plottery_lib re-exports this crate and turns the fonts into geometry:

use plottery_lib::*;

let font = Font::bundled(BundledFont::HersheySans);
let layer = Text::new("Hello plotter", &font)
    .size(2.0) // em height in cm
    .to_layer(SampleSettings::default())?;
layer.write_svg("hello.svg".into(), 10.0)?;

Usage without Plottery

Pick a font and feed the bytes to your own parser. kind() tells you what the bytes are:

use plottery_fonts::{BundledFont, FontKind};

let font = BundledFont::ReliefSingleLine;
let bytes: &[u8] = font.bytes();

match font.kind() {
    FontKind::Stroke => {}     // SVG 1.1 font: <glyph d="..."> strokes, plus <hkern> pairs
    FontKind::SingleLine => {} // TrueType whose contours are strokes: do not close them
    FontKind::Outline => {}    // TTF/OTF, the strokes live in its OpenType `SVG ` table
}

for font in BundledFont::ALL {
    let credit = font.credit();
    println!("{} by {} ({})", font.family(), credit.author, credit.licence.name());
}

file_name() gives the original file name, credit() the author, source URL and licence, and Licence::text() the full licence text for your "about" screen.

Licences

Everything is under the SIL Open Font License 1.1 or the Hershey font licence. Both allow commercial use and bundling. The Hershey licence asks that its acknowledgement travels with the data, so keep LICENSES/ (or Licence::Hershey.text()) in anything you ship. Per-font credits are in LICENSES/CREDITS.md.
