Per-band decode parameters.

Fields

start: [usize; 3]

Region start (brick-local).

end: [usize; 3]

Region end (exclusive).

class: usize

Context class.

parent: Option<usize>

Parent band index.

pshift: [u32; 3]

Parent-position shift per axis (1 if the parent level splits it).

npass: usize

Number of passes.

pkey: [usize; 8]

Predictor key per pass.

m: i32

Dequantization step mantissa.

sh: u32

Dequantization step shift.

w: f64

Synthesis-basis weight.

org: [usize; 3]

Origin of the subband this region belongs to (parent mapping); equal to start for whole bands, the band start for a code-block.

raster: bool

Raster order inside the region (one lane, every earlier line visible) instead of parity passes.

ax: bool

Axis-grouped value taps: the three line taps (and the learned model’s line values) sum z-axis / y-axis / diagonal lines instead of face / diagonal / far lines.

nl: usize

Lanes this region’s lines are dealt to (0 = all of the coder’s lanes).

Trait Implementations

impl Clone for BandInfo

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 BandInfo

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

Formats the value using the given formatter.
