The package provides a parser for OpenType fonts.
```rust use opentype::Font; use opentype::table::NamingTable; use std::fs::File;
let path = "SourceSerifPro-Regular.otf"; let mut file = File::open(path).unwrap(); let font = Font::read(&mut file).unwrap();
match font.fontheader { Some(ref table) => asserteq!(table.unitsPerEm, 1000), _ => unreachable!(), } match font.horizontalheader { Some(ref table) => asserteq!(table.Ascender, 918), _ => unreachable!(), } match font.namingtable { Some(NamingTable::Format0(ref table)) => { let strings = table.strings().unwrap(); asserteq!(&strings[1], "Source Serif Pro"); assert_eq!(&strings[9], "Frank Grießhammer"); }, _ => unreachable!(), } ```
