Image
This is a Rust image processing library designed for encoding and decoding various image file formats and manipulating pixels. It provides a digital image manipulation toolkit and a set of image format codecs to read data from files and write memory buffers into standard formats.
The library features a pure-Rust processing pipeline to ensure memory safety and cross-platform compatibility. It includes a pluggable hook system for dynamic format registration, allowing external crates to register custom decoders and encoders at runtime.
The capability surface covers geometry manipulation for resizing, cropping, and rotating images, as well as color management for space conversions and gradient generation. It includes tools for extracting and embedding metadata such as Exif and ICC profiles, and provides functions for visual filter application and appearance adjustments.
Quality assurance is handled through fuzz testing, using randomized input generation to identify vulnerabilities in binary file parsing.
