Struct libavif::Encoder

pub struct Encoder { /* fields omitted */ }

AVIF image encoder

Implementations

impl Encoder

pub fn new() -> Self

Create a new encoder with default settings

Defaults

• max_threads -> 1
• quantizer -> 0
• quantizer_alpha -> 0
• speed -> 10

pub fn max_threads(&self) -> usize

Get the maximum allowed number of threads this Encoder can use

pub fn set_max_threads(&mut self, max_threads: usize) -> &mut Self

Set the maximum allowed number of threads this Encoder can use

pub fn quantizer(&self) -> u8

Get quantizer value for the YUV channels

pub fn set_quantizer(&mut self, quantizer: u8) -> &mut Self

Set the quantizer value for the YUV channels

Must be between 0 and 63.

• 0 - lossless
• 63 - lowest quality

pub fn quantizer_alpha(&self) -> u8

Get quantizer value for the alpha channel

pub fn set_quantizer_alpha(&mut self, quantizer_alpha: u8) -> &mut Self

Set the quantizer value for the alpha channel

Must be between 0 and 63.

• 0 - lossless
• 63 - lowest quality

pub fn speed(&self) -> u8

Get the speed of this Encoder

pub fn set_speed(&mut self, speed: u8) -> &mut Self

Set the speed of this Encoder

Must be between 0 and 10.

• 10 - fastest
• 0 - slowest

pub fn encode(&self, image: &AvifImage) -> Result<AvifData<'static>, Error>

Encode an AvifImage using the settings from this Encoder

Trait Implementations

impl Default for Encoder

fn default() -> Self

Returns the "default value" for a type.

impl Drop for Encoder

fn drop(&mut self)

Executes the destructor for this type.
