Enum PostEffect 

pub enum PostEffect {
    Grain {
        intensity: f32,
        seed: u64,
        animated: bool,
    },
    Vignette {
        intensity: f32,
        radius: f32,
    },
    Pixelate {
        size: u32,
    },
    ProgressiveBlur {
        direction: BlurDirection,
        start: f32,
        max_radius: f32,
    },
}

A post-processing effect applied to the full frame buffer after Skia renders. Effects are pure Rust, deterministic, and applied in declaration order.

Variants

Grain

Film grain noise overlaid on every pixel.

Fields

intensity: f32

Noise strength clamped to 0..1. Default: 0.15.

seed: u64

Base seed for the noise hash. Default: 42.

animated: bool

When true, the pattern changes per frame (seed ^ frame_index). Default: true.

Vignette

Darken the frame edges towards the corners.

Fields

intensity: f32

Darkness strength clamped to 0..1. Default: 0.5.

radius: f32

Fraction of the half-diagonal where darkening starts. Default: 0.75.

Pixelate

Reduce spatial resolution by averaging square pixel blocks.

Fields

size: u32

Block size in pixels, clamped to 1..=256. Default: 8.

ProgressiveBlur

Blur that grows from zero at start to max_radius at the frame edge.

Fields

direction: BlurDirection

Which edge gets the maximum blur. Default: bottom.

start: f32

Fraction of the frame height where blur begins (0.0..1.0). Default: 0.5.

max_radius: f32

Maximum box-blur radius in pixels at the far edge. Default: 12.0.
