Struct JxlAnimation 

pub struct JxlAnimation {
    pub tps_numerator: u32,
    pub tps_denominator: u32,
    pub num_loops: u32,
    pub have_timecodes: bool,
}

JPEG-XL animation header (per ISO 18181-1, Section 7.1.3).

Defines the timing base for all frames in an animated JPEG-XL image. Frame durations are expressed as duration_ticks * tps_denominator / tps_numerator seconds.

Fields

tps_numerator: u32

Tick numerator for frame timing (tps_numerator). Together with tps_denominator, defines the time unit for frame durations. For example, tps_numerator = 1000 and tps_denominator = 1 gives millisecond-resolution timing.

tps_denominator: u32

Tick denominator for frame timing (tps_denominator).

num_loops: u32

Number of loops (0 = infinite loop).

have_timecodes: bool

Whether timecodes are present in frame headers.

Implementations

impl JxlAnimation

pub fn new(tps_numerator: u32, tps_denominator: u32) -> CodecResult<Self>

Create an animation header with the given tick rate.

Errors

Returns error if tps_numerator or tps_denominator is zero.

pub fn millisecond() -> Self

Create an animation header for millisecond-resolution timing (tps_numerator = 1000, tps_denominator = 1).

pub fn with_num_loops(self, num_loops: u32) -> Self

Set the number of loops (0 = infinite).

pub fn with_timecodes(self, have_timecodes: bool) -> Self

Enable timecodes in frame headers.

pub fn duration_seconds(&self, ticks: u32) -> f64

Calculate the frame duration in seconds for a given number of ticks.

Trait Implementations

impl Clone for JxlAnimation

fn clone(&self) -> JxlAnimation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JxlAnimation

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

Formats the value using the given formatter.

impl PartialEq for JxlAnimation

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