Module samsung 

Samsung SRW compressions.

TIFF compression	name	layout
32770 + tag 40976	V0	per-row offsets; 16-sample blocks with a direction bit and four adaptive bit lengths; rows stored as 2x2-transposed pairs
32772	V1	single predictive Huffman stream (fixed 10-bit table), see crate::nikon_huffman
32773	V2	rows aligned to 16 bytes; 16-sample blocks with motion-compensated prediction from previous rows, adaptive bit lengths and a quantisation scale

V0 and V2 read bits MSB-first from little-endian 32-bit words, fetching a new word only when the buffered bits run out (Ph1Bits); V2 relies on this exact fetch pattern for its row alignment.

Structs

Ph1Bits

MSB-first reader over little-endian 32-bit words with lazy word fetches. Reading past the end yields all-ones words and is flagged.

Functions

decode_v0

Decode Samsung V0 (compression 32770 with a row offset table).

decode_v0_reference

Sequential reference implementation of Samsung V0 (see decode_v0); kept as the specification the two-phase decoder is tested against.

decode_v0_with

decode_v0 with explicit control over parallelism.

decode_v1

Decode Samsung V1 (compression 32772). Returns the row in which the data ran out (None when the stream was complete).

decode_v2

Decode Samsung V2 (compression 32773). src starts at the image data.
