# LibRaw: RAW image decoding/processing library

LibRaw is a library for reading RAW files from digital photo cameras (CRW/CR2, NEF, RAF, DNG, MOS, KDC, DCR, etc.; virtually all RAW formats are supported). It pays special attention to correct retrieval of data required for subsequent RAW conversion.

The library is intended for embedding in RAW converters, data analyzers, and other programs using RAW files as the initial data.
