Expand description

A CSS-like filter: each field is one filter function, mirroring CSS naming. Every field is optional; unset means identity (no effect). Amounts follow the CSS convention: brightness/contrast/saturate are multipliers (1.0 = identity), grayscale/sepia/invert are 0.0..=1.0 blends (0 = identity), blur is a radius (a Length in px), and hueRotate is an Angle. The functions are applied in a fixed canonical order (blur → brightness → contrast → saturate → grayscale → sepia → invert → hueRotate), not the declared order, so listing the same function twice is not supported. See [crate::filter].

Fields§

§blur: Option<Length>

Gaussian blur radius (a Length, px). 0/absent → no blur.

§brightness: Option<f32>

Brightness multiplier (1.0 = identity, 0.0 = black, >1 brighter).

§contrast: Option<f32>

Contrast multiplier about mid-grey (1.0 = identity).

§saturate: Option<f32>

Saturation multiplier (1.0 = identity, 0.0 = grayscale, >1 more vivid).

§grayscale: Option<f32>

Grayscale amount (0.0 = identity, 1.0 = fully desaturated).

§sepia: Option<f32>

Sepia amount (0.0 = identity, 1.0 = full sepia tone).

§invert: Option<f32>

Invert amount (0.0 = identity, 1.0 = fully inverted colors).

§hue_rotate: Option<Angle>

Hue rotation (an Angle; number = degrees). 0/absent → no rotation.
