Struct GaussianBlur 

pub struct GaussianBlur {
    pub std_deviation: f32,
    pub n_decimations: usize,
    pub kernel: [f32; 13],
    pub kernel_size: u8,
    pub edge_mode: EdgeMode,
}

A gaussian blur.

Fields

std_deviation: f32

The standard deviation.

n_decimations: usize

Number of 2× decimation levels to use (0 means no decimation, direct convolution).

kernel: [f32; 13]

Pre-computed Gaussian kernel weights for the reduced blur. Only the first kernel_size elements are valid.

kernel_size: u8

Actual length of the kernel (rest is padding up to MAX_KERNEL_SIZE).

edge_mode: EdgeMode

Edge mode for handling out-of-bounds sampling.

Implementations

impl GaussianBlur

pub fn new(std_deviation: f32, edge_mode: EdgeMode) -> Self

Create a new Gaussian blur filter with the specified standard deviation.

This precomputes the decimation plan, kernel, and radius for optimal performance.

Trait Implementations

impl Debug for GaussianBlur

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
