## 项目历史与用法

LibRaw is a RAW photo decoding library created to turn Dave Coffin's dcraw codebase into an embeddable, thread-safer library with expanded metadata and camera-format support.

### 项目历史

The LibRaw project states that it launched in 2008 based on Dave Coffin's dcraw.c utility. Its goals were to convert dcraw into a library usable by other programs, remove global-variable style constraints, improve thread safety, import dcraw changes, and expand metadata extraction.

LibRaw's history is inseparable from dcraw. The project notes that dcraw support was reduced to a minimum in 2015 and ceased in 2018; after that, new camera and format support was handled by the LibRaw team. The rendering path inherited from dcraw remained important, while LibRaw moved contributor demosaic and post-processing experiments into separate projects when they became hard to maintain in the core library.

### 采用历史

LibRaw was adopted broadly because camera vendors produce many undocumented or semi-documented RAW formats and applications need a maintained decoding layer. Its official documentation describes embedding in RAW converters, data analyzers, and other programs that use RAW files as input, and its supported-camera list spans phone cameras, drones, cinema cameras, DSLRs, and mirrorless systems.

### 使用方式

Homebrew installs the library and sample utilities such as dcraw_emu, raw-identify, simple_dcraw, and postprocessing_benchmark. Developers use the API when they need to identify cameras, read RAW metadata, unpack sensor data, or feed image data to a separate conversion pipeline.

### 为什么软件包爱好者会关心

LibRaw is one of the cleaner examples of turning a famous single-file Unix utility into a library package. It matters to maintainers because many graphics applications can share one camera-support substrate instead of vendoring dcraw snapshots or maintaining format decoders independently.

### 时间线

- 1997: Dave Coffin's dcraw copyright lineage begins, later forming LibRaw's base.
- 2008: LibRaw project launched from dcraw.c.
- 2015: LibRaw records dcraw support being reduced to a minimum.
- 2018: LibRaw records dcraw support ceasing, with camera-format support handled by the LibRaw team thereafter.
- 2026: LibRaw documentation and supported-camera pages described the 0.22 camera support generation.

### Related projects

- LibRaw is related to dcraw, RawDigger, FastRawViewer, RAW converter applications, camera-specific RAW formats such as CRW, CR2, NEF, RAF, DNG, MOS, KDC, and DCR, and the LibRaw demosaic pack projects.
