Struct Encoder

pub struct Encoder<'a> { /* private fields */ }

An encoder for WebP images. It uses the default configuration of libwebp.

Implementations

impl<'a> Encoder<'a>

pub fn new( image: &'a [u8], layout: PixelLayout, width: u32, height: u32, ) -> Self

Creates a new encoder from the given image data. The image data must be in the pixel layout of the color parameter.

pub fn from_rgb(image: &'a [u8], width: u32, height: u32) -> Self

Creates a new encoder from the given image data in the RGB pixel layout.

pub fn from_rgba(image: &'a [u8], width: u32, height: u32) -> Self

Creates a new encoder from the given image data in the RGBA pixel layout.

pub fn encode(&self, quality: f32) -> WebPMemory

Encode the image with the given quality. The image quality must be between 0.0 and 100.0 inclusive for minimal and maximal quality respectively.

pub fn encode_lossless(&self) -> WebPMemory

Encode the image losslessly.

pub fn encode_simple( &self, lossless: bool, quality: f32, ) -> Result<WebPMemory, WebPEncodingError>

pub fn encode_advanced( &self, config: &WebPConfig, ) -> Result<WebPMemory, WebPEncodingError>

Trait Implementations

impl<'a> From<&'a AnimFrame<'a>> for Encoder<'a>

fn from(f: &'a AnimFrame<'_>) -> Self

Converts to this type from the input type.
