Crate flashraw_codecs 

flashraw-codecs

Reusable RAW compression codecs. Each codec decodes into caller-provided buffers (or row sinks) and never allocates full-image intermediates.

Codecs are independent of container formats so they can be fuzzed, benchmarked and tested in isolation (see fuzz/ and benches/).

Modules

canon_cr2

Canon CR2 lossless-JPEG payload with vertical slicing.

canon_crw

Canon CRW (“CIFF”) compressed raw codec, used by the PowerShot G1..G6, Pro1, S30..S70 and EOS D30/D60/10D/300D generation of cameras.

canon_crx

Canon CRX: the raw codec of CR3 files (EOS R/M/D series since 2018, PowerShots).

canon_sraw

Canon sRAW / mRAW (CR2 “small raw”) decoding.

dct12

12-bit DCT tiles used by early Blackmagic cinema DNGs (compression 7 with an SOF1 frame instead of SOF3).

deflate

Deflate (zlib) payloads and TIFF/DNG predictors.

dng_opcodes

DNG opcode lists (OpcodeList1/2/3, DNG spec 1.3+ chapter 7).

fuji_compressed

Fujifilm compressed RAF codec (lossless and lossy, X-Trans and Bayer).

hasselblad

Hasselblad lossless JPEG variant (3FR/FFF, Imacon/Flexcolor, H/X/CFV backs).

jpeg

Baseline (lossy) JPEG decoding for lossy DNG tiles and preview conversion.

kodak

Kodak entropy coders and pixel transforms.

leaf

Restart-interval parallel lossless JPEG, as written by Leaf (and Phase One-era Leaf/Mamiya backs) for MOS files.

ljpeg

Lossless JPEG (ITU T.81 process 14, SOF3) decoder.

misc_packed

Packings used by headerless sensor dumps (CHDK, phone/action-camera dumps, Raspberry Pi, old compacts).

nikon_huffman

Nikon NEF Huffman compression, plus the predictive Huffman engine it shares with Pentax PEF and Samsung SRW (compression 32772).

nikon_packed

The “load flags” family of bit-packed layouts.

olympus

Olympus / OM System ORF lossless compression.

packed

Unpacking of uncompressed, bit-packed sensor data.
