Flutter LibRaw

The Flutter LibRaw package aims to provide the ability to read camera RAW files to Dart/Flutter applications.

This package is a wrapper around the C/C++ LibRaw library using Dart FFI.

Note that this project is still in its early stages and so may not yet provide complete/full functionality. We will be building up functionality over the next few months through numerous small iterative releases.

About The Project

The Flutter LibRaw library provides a simple and unified interface for extracting the following out of RAW files generated by digital photo cameras:

  • RAW data (pixel values)
  • Metadata necessary for processing RAW (geometry, CFA / Bayer pattern, black level, white balance, etc.)
  • Embedded preview / thumbnail.

The library is intended for use with programs that work with RAW files, such as:

  • RAW viewers
  • RAW converters
  • RAW data analyzers

Using the Flutter LibRaw library allows one to focus on the substantive part of processing the data contained in RAW files, without getting distracted by the wide variety of RAW file and metadata formats, compression algorithms, etc.

Features

  • Support for RAW files from a wide variety of cameras.
