OpenType

The package provides a parser for OpenType fonts. It might be helpful to have a look at a higher-level parser called font, which internally relies on this package.

Example

extern crate opentype;
extern crate truetype;

use opentype::File;
use truetype::{FontHeader, HorizontalHeader, NamingTable};

macro_rules! ok(($result:expr) => ($result.unwrap()));

let path = "SourceSerifPro-Regular.otf";
let mut reader = ok!(std::fs::File::open(path));
let file = ok!(File::read(&mut reader));

assert_eq!(ok!(ok!(file[0].take::<_, FontHeader>(&mut reader))).units_per_em, 1000);
assert_eq!(ok!(ok!(file[0].take::<_, HorizontalHeader>(&mut reader))).ascender, 918);
let strings = match ok!(ok!(file[0].take::<_, NamingTable>(&mut reader))) {
    NamingTable::Format0(ref table) => ok!(table.strings()),
    _ => unreachable!(),
};
assert_eq!(&strings[1], "Source Serif Pro");
assert_eq!(&strings[9], "Frank Grießhammer");
