Struct NikonMeta 

pub struct NikonMeta {
    pub version: [u8; 2],
    pub vpred: [[u16; 2]; 2],
    pub tree: usize,
    pub split_row: usize,
    pub curve: Vec<u16>,
}

Decoded Nikon compression metadata (makernote tag 0x96 “NEFLinearizationTable”).

Fields

version: [u8; 2]

Version bytes (0x44 0x10/0x20/0x40 lossy, 0x46 0x30 lossless, …).

vpred: [[u16; 2]; 2]

tree: usize

Index into NIKON_TREES.

split_row: usize

Row at which the “after split” tree takes over (0 = none).

curve: Vec<u16>

Linearisation curve indexed by the clamped predictor value (0x4000 entries).

Implementations

impl NikonMeta

pub fn parse(meta: &[u8], order: ByteOrder, bits: u32) -> Result<Self>

Parse the blob at makernote tag 0x96 (or 0x8C). meta starts at the tag’s value and may extend to the end of the file (parsing may read beyond the tag).

pub fn is_lossless(&self) -> bool

Whether this is a lossless stream (no curve, identity mapping).

pub fn curve_max(&self) -> u16

Largest value the curve produces (the effective white level of lossy files).

Trait Implementations

impl Clone for NikonMeta

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NikonMeta

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
