Expand description

Parameters for the noise watermark drawn over the composed sprite.

Fields§

§count: u32

Number of noise marks. Capped at 1_000_000. count multiplied by the pixels one mark covers (1, size, or size squared, by pattern) must not exceed 4_000_000.

§size: u32

Edge length of one mark, in pixels, for NoisePattern::Lines and NoisePattern::Grid. Capped at 64.

§blur_sigma: f32

Gaussian blur applied after the noise. Zero disables it. Capped at 32.0.

§alpha: u8

Opacity of each mark, 0 (invisible) to 255 (opaque). Marks are alpha-blended onto the sprite.

§color_range: (u8, u8)

Inclusive channel range each mark’s colour is drawn from. .0 must not exceed .1.
