# OpenType [![Package][package-img]][package-url] [![Documentation][documentation-img]][documentation-url] [![Build][build-img]][build-url]

The package provides a builder and parser of OpenType fonts. It might be helpful

to have a look at a higher-level abstraction called [`font`][font], which

internally relies on this package.

## Example

```rust

use opentype::truetype::tables::names::{Names, NameID};

use opentype::truetype::tables::{FontHeader, HorizontalHeader};

use opentype::File;

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

let path = "SourceSerifPro-Regular.otf";

let mut tape = ok!(std::fs::File::open(path));

let File { mut fonts } = ok!(File::read(&mut tape));

let font_header: FontHeader = ok!(ok!(fonts[0].take(&mut tape)));

assert_eq!(font_header.units_per_em, 1000);

let horizontal_header: HorizontalHeader = ok!(ok!(fonts[0].take(&mut tape)));

assert_eq!(horizontal_header.ascender, 918);

let names: Names = ok!(ok!(fonts[0].take(&mut tape)));

let names = names

    .iter()

    .map(|((_, _, _, name_id), value)| (name_id, value))

    .collect::>();

assert_eq!(ok!(names[&NameID::FullFontName].as_ref()), "Source Serif Pro");

assert_eq!(ok!(names[&NameID::DesignerName].as_ref()), "Frank Grießhammer");

```
