chromahash

Modern, high-quality image placeholder representation for professional formats (LQIP)

chromahash encodes an image into a compact, fixed 32-byte Low Quality Image Placeholder (LQIP) and decodes it back into a low-fidelity preview. Color is encoded in the perceptually-uniform OKLAB space with wide-gamut input support (sRGB, Display P3, Adobe RGB, BT.2020, ProPhoto RGB), an adaptive DCT grid, and alpha — all within the same fixed size.

This is the Rust implementation. It is part of a multi-language project whose implementations are validated bit-exact against a shared specification, so the same input produces the same placeholder in every language. The crate is zero-dependency.

[dependencies]
chromahash = "0.5"

See the project repository for the full format specification, the other language implementations, and usage examples.

Note: ChromaHash is a pre-1.0 Draft format — the bitstream is not yet guaranteed stable across versions.
