flashraw-cli

FlashRaw is a fast, memory-safe camera RAW decoder written in Rust, with Rust, C, C++, Python and JavaScript (WebAssembly) bindings. It decodes about 40 RAW formats (CR2, CR3, NEF, ARW, RAF, DNG, RW2, ORF, PEF and more) with SIMD kernels, multithreading and an optional GPU backend, converts to display-ready RGB with ICC colour management, and runs in the browser.

The flashraw command-line tool of FlashRaw: inspect, decode, convert and benchmark camera RAW files.

cargo install flashraw-cli                       # CPU only
cargo install flashraw-cli --features gpu,jpegxl # + GPU backend and JPEG XL DNG

The default build has neither the gpu nor the jpegxl feature: --backend gpu and JPEG XL compressed DNG need the second command.

flashraw info photo.CR3                          # metadata summary (--json for scripts)
flashraw preview photo.CR3 preview.jpg           # embedded JPEG, no sensor decode
flashraw decode photo.CR3 out.tif --output rgb16 # develop to a 16-bit TIFF
flashraw supported                               # formats and the status of each mode
flashraw --help                                  # every command and option
