## プロジェクトの歴史と使われ方

dcraw is Dave Coffin's portable ANSI C decoder for raw digital camera photos. The official site describes its goal as decoding raw images from any digital camera on any operating system, and calls it a standard tool inside and outside open source.

### プロジェクトの歴史

The official dcraw page says the RCS history of dcraw.c begins with its conception on February 23, 1997. Instead of using a public forge as its primary home, dcraw has long been distributed from Coffin's own site as source files, an RCS file, tarballs, translations, and an official manpage.

### 採用の歴史

dcraw became important because camera vendors shipped proprietary Windows and Mac tools while Unix and open-source users needed a portable way to process raw files. The official page lists many applications and plugins that used dcraw, copied parts of dcraw.c, or treated the source as practical documentation for camera formats.

### 使われ方

The manpage documents dcraw as a command-line decoder that can decode raw photos, display metadata, and extract thumbnails. Its options cover identifying files, outputting to stdout, controlling white balance, extracting embedded thumbnails, and producing image formats suitable for further processing.

### パッケージ好きにとっての重要性

dcraw is package-manager folklore because it compressed a sprawling compatibility problem into one portable C program. For distributions, graphics stacks, and photo tools, it served as both an executable utility and a reference implementation for raw camera formats.

### タイムライン

- 1997: dcraw.c history begins according to the official RCS file note
- 2003: Official page links Dave Coffin's Digital Outback Photo essay
- 2005: Official page links press and interview coverage around raw-photo decoding
- 2015: Official manpage updated March 3, 2015
