* raw: decode Sony cRAW, Panasonic RW2 (RawFormat 5) and uncompressed Olympus ORF
- sony.rs: compressed ARW (SonyRawFileType 2): 32-pixel runs as two
16-byte blocks of 11-bit max/min, 4-bit positions and 7-bit deltas,
then the SonyToneCurve (0x7010) to 14 bits. From Dietz (EI 2016) and
the RawDigger write-up; bit order and curve scale by observation.
- rw2.rs: RawFormat 5 12/14-bit packing (10/9 pixels per 16-byte LE
block), stored in 0x4000-byte pages split at 0x1FF8 (observed), with
PanasonicRaw CFA, black, linearity limit, WB and sensor borders.
RawFormat 4 and older stay unsupported (preview fallback).
- orf.rs: uncompressed 16-bit ORF (E-1, E-400): left-justified
samples, EXIF CFAPattern, Olympus ImageProcessing black / WB /
ValidBits / crop; compressed ORF stays unsupported but its maker-note
preview (CameraSettings 0x0101/0x0102) is now found.
- testgen: cRAW, RW2 and ORF encoders/builders; vendor_codecs tests
round-trip each codec; hostile tests fuzz/truncate all three.

* raw: clean-room camera raw decoder and developer (photocraft-raw)
A new standalone crate (no workspace deps, wasm-safe, no unsafe) written
from TIFF 6.0, TIFF/EP, the DNG 1.7 spec, ITU-T T.81 Annex H and published
demosaicing papers:
- Lossless JPEG (LJ92) decoder: predictors 1-7, point transform, restart
intervals, combined Huffman+extra-bits fast table.
- DNG: uncompressed (8-16 bit, packed) and LJ92, strips and tiles, CFA and
LinearRaw, linearization, black level (repeat, deltas), white level,
active area, default crop, ColorMatrix/CameraCalibration/ForwardMatrix
interpolation by CCT, AnalogBalance, AsShotNeutral/WhiteXY,
BaselineExposure, orientation.
- CR2 (LJ92 slices, SensorInfo borders, ColorData as-shot WB, measured
black) and TIFF/EP raws (NEF/ARW/PEF uncompressed or LJ92, incl. Sony
lossless ARW tiles, Nikon/Sony documented black and WB tags).
- Develop: black/white scaling, WB with highlight clipping, bilinear /
Malvar-He-Cutler / AHD demosaic (rayon bands, sequential on wasm),
camera -> XYZ D50 -> ProPhoto, exposure, gamma 1.8, 16-bit, orientation.
- Embedded JPEG preview finder; clear Unsupported errors for CR3, RAF,
ORF, RW2, vendor-compressed NEF/ARW/PEF, lossy/JXL/float DNG, X-Trans.
- Limits checked before every allocation; testgen feature with an LJ92
encoder and DNG/CR2/TIFF-EP writers; round-trip, colour-reference,
truncation and corruption tests.
Registered as a standalone crate in xtask layers.

* io: open camera raws through photocraft-raw (16-bit ProPhoto), preview fallback
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* raw: DNG GainMap opcode, fuzz targets, stress tools; open raws from the apps
- Apply DNG OpcodeList2 GainMap (lens shading, e.g. phone DNGs); report other opcodes.
- cargo-fuzz targets (develop, ljpeg) and a mutation stress example.
- Raw extensions in the desktop/web open dialogs and the batch folder list.
- file.open returns the import notes (how a raw was developed, preview fallback).
- codecs: the camera raw refusal points at photocraft-raw.
