libopenraw is an ongoing project to provide a free software implementation for camera RAW files decoding. One of the main reason is that dcraw is not suited for easy integration into applications, and there is a need for an easy to use API to build free software digital image processing application.

It also has the goal to address missing feature from dcraw like meta-data decoding and easy thumbnail extraction.


This is currently a work in progress. The currently unreleased code is available in git. See GettingTheCode.
