Struct image::codecs::webp::WebPQuality

impl WebPQuality

pub const MIN: u8 = 0u8

Minimum lossy quality value (0).

pub const MAX: u8 = 100u8

Maximum lossy quality value (100).

pub const DEFAULT: u8 = 80u8

Default lossy quality (80), providing a balance of quality and file size.

pub fn lossless() -> Self

Lossless encoding.

pub fn lossy(quality: u8) -> Self

👎Deprecated: Lossy encoding will be removed in a future version. See: https://github.com/image-rs/image/issues/1984

Lossy encoding. 0 = low quality, small size; 100 = high quality, large size.

Values are clamped from 0 to 100.
