Fields

dimensions: (u32, u32)

Reference-grid image dimensions derived from SIZ.

components: u16

Number of codestream components.

bit_depth: u8

Maximum component precision in bits.

tile_size: (u32, u32)

Reference tile width and height.

tile_count: (u32, u32)

Number of reference tiles horizontally and vertically.

component_info: Vec<J2kCodestreamComponentHeader>

Per-component SIZ precision and sampling metadata.

resolution_levels: u8

Number of resolution levels from COD.

has_mct: bool

Whether COD enables a multi-component transform.

reversible: bool

Whether COD selects the reversible 5/3 transform.

high_throughput: bool

Whether the codestream advertises high-throughput block coding.

Trait Implementations

impl Clone for J2kCodestreamHeaderMetadata

fn clone(&self) -> J2kCodestreamHeaderMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for J2kCodestreamHeaderMetadata

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

Formats the value using the given formatter.

impl Eq for J2kCodestreamHeaderMetadata

impl PartialEq for J2kCodestreamHeaderMetadata

fn eq(&self, other: &J2kCodestreamHeaderMetadata) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
