Allsorts Font Shaping Engine 0.15 Release

12 June 2024

Allsorts now supports variable fonts, CFF2, and can generate font specimen documents.

Allsorts is a Rust crate (library) that can parse OpenType, WOFF, and WOFF2 fonts, shape text, and subset fonts. We use it in Prince for all font parsing, shaping, and subsetting.

A lot has happened since we last wrote about Allsorts all the way back in 2021. There have been 14 releases since then. In that time Allsorts gained support for variable fonts, CFF2 outlines, and creating font specimen documents, as well as a few bug fixes and improvements.

Announcing the Allsorts Font Shaping Engine

20 November 2019

Today YesLogic is open-sourcing the Allsorts font parser, shaping engine, and subsetter for OpenType, WOFF, and WOFF2 under the Apache 2.0 license. Allsorts was extracted from the Prince HTML to PDF typesetting and layout tool and is implemented in Rust.

Prince is a tool that converts HTML and CSS into well laid out PDFs. Our customers use it to produce books, restaurant menus, invoices, business cards, and much more. Two years ago YesLogic set out to improve the font parsing and shaping in Prince.
