Struct WebpEncoder 

pub struct WebpEncoder { /* private fields */ }

Encodes 8-bit RGB images to WebP.

Construct with WebpEncoder::new (lossless), WebpEncoder::lossless, or WebpEncoder::lossy, then encode via the EncodeImage trait.

Implementations

impl WebpEncoder

pub fn new() -> Self

Creates an encoder with the default configuration (lossless VP8L).

pub fn lossless() -> Self

Creates an encoder that produces a lossless VP8L bitstream.

pub fn lossy(quality: u8) -> Self

Creates an encoder that produces a lossy VP8 bitstream at the given quality (0..=100).

pub fn config(&self) -> WebpConfig

Returns the encoder’s configuration.

Trait Implementations

impl Clone for WebpEncoder

fn clone(&self) -> WebpEncoder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WebpEncoder

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

Formats the value using the given formatter.

impl Default for WebpEncoder

fn default() -> WebpEncoder

Returns the “default value” for a type.

impl EncodeImage<Rgb8> for WebpEncoder

fn encode_image( &self, image: ImageRef<'_, Rgb8>, out: &mut Vec<u8>, ) -> Result<usize>

Encode image into out (appended), returning the number of bytes written.

impl EncodeImage<Rgba8> for WebpEncoder

fn encode_image( &self, image: ImageRef<'_, Rgba8>, out: &mut Vec<u8>, ) -> Result<usize>

Encode image into out (appended), returning the number of bytes written.
