Module nikon_packed 

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

Many Nikon, Pentax and Samsung uncompressed raws are described by a handful of “load flags” rather than by standard TIFF packing:

flag bits	meaning
1	one padding byte after every 10 samples (Nikon D100 “compressed”)
2	rows stored as two interlaced fields (even rows, then odd rows)
4	the second field starts at a separate offset
8 | 16	bits are gathered in little-endian units of 16/24/32 bits, MSB first
64	swap each pair of output columns
128	rows are padded to an even number of bytes

PackedSpec::fast_layout maps the common combinations onto crate::packed (parallel, SIMD); everything else uses the exact sequential path in decode, which is the specification.

Structs

PackedSpec

A load-flags packed raster description.

Functions

decode

Decode src into out (rows of stride samples). Truncated input is an error (decoding aborts at the first row that starts past EOF) unless lenient (recovering truncated data): then every complete sample is decoded and the rest are left zero (out must be zeroed).

decode_exact

Exact sequential decode of any load-flags layout (the specification).
