Struct webp::Encoder

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

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_image(image: &'a DynamicImage) -> Result<Self, &str>

Creates a new encoder from the given image.

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

Emcode 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

Emcode the image losslessly.
