Whether to write SOP marker segments before packets.

write_eph: bool

Whether to write EPH markers after packet headers.

use_mct: bool

Whether to apply JPEG 2000 multi-component transform.

num_layers: u8

Number of cumulative quality layers.

quality_layer_byte_targets: Vec<u64>

tile_size: Option<(u32, u32)>

Optional tile size for multi-tile codestreams.

Trait Implementations

impl Clone for JpegToHtj2kEncodeOptions

fn clone(&self) -> JpegToHtj2kEncodeOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JpegToHtj2kEncodeOptions

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

Formats the value using the given formatter.

impl Default for JpegToHtj2kEncodeOptions

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for JpegToHtj2kEncodeOptions

fn eq(&self, other: &JpegToHtj2kEncodeOptions) -> 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.
