Raw

jpgfromraw-lib

Library fork of Chris Down's jpgfromraw, published under a separate crate name because jpgfromraw already belongs to upstream on crates.io.

This fork keeps the fast embedded JPEG extraction code and exposes it as a Rust library for apps that need RAW previews without shelling out to the CLI.

Usage

use jpgfromraw_lib::{process_file_bytes, FindJpegType};

let jpeg = process_file_bytes(path, FindJpegType::Largest).await?;

FindJpegType::Largest usually returns the full-size embedded preview. FindJpegType::Smallest usually returns the thumbnail.

The crate also exports:

  • process_file to write an extracted JPEG to disk.
  • SUPPORTED_EXTENSIONS for the supported RAW/camera extension list.

Notes

  • License: MIT, preserving upstream attribution.
  • Repository: https://github.com/ioma8/jpgfromrawlib
  • Some RAW fallbacks build vendored C/C++ tools, so consumers may need a C compiler and CMake available during builds.
