hayro-jbig2

Crates.io Documentation

A memory-safe, pure-Rust JBIG2 decoder.

hayro-jbig2 decodes JBIG2 images as specified in ITU-T T.88 (also known as ISO/IEC 14492). JBIG2 is a bi-level image compression standard commonly used in PDF documents for compressing scanned text documents.

Status

This crate is currently under development.

Safety

By default, the crate has the simd feature enabled, which uses the fearless_simd crate to accelerate decoding of JBIG2 images with halftoning. If you want to eliminate any usage of unsafe in this crate as well as its dependencies, you can simply disable this feature and still get very good performance in the vast majority of cases. Unsafe code is forbidden via a crate-level attribute.
