Struct GaussianBlurNode 

pub struct GaussianBlurNode {
    pub sigma: f32,
    /* private fields */
}

Two-pass separable Gaussian blur.

Fields

sigma: f32

Standard deviation in pixels. Effective range [0.5, 20.0] (values outside are clamped); a larger sigma is truncated to a 15-tap kernel.

Implementations

impl GaussianBlurNode

pub fn new(sigma: f32) -> Self

Creates a Gaussian blur node with the given standard deviation.

Trait Implementations

impl RenderNode for GaussianBlurNode

Available on crate feature wgpu only.

fn pass_count(&self) -> usize

Number of render passes (default: 1). Multi-pass nodes (e.g. gaussian blur) return 2 or more.

fn process( &self, inputs: &[&Texture], outputs: &[&Texture], ctx: &RenderContext, )

Run the GPU render pass.

fn input_count(&self) -> usize

Number of input textures required by this node (default: 1).

fn output_dimensions(&self, in_w: u32, in_h: u32) -> (u32, u32)

Output dimensions this node produces given its input dimensions.

fn set_param(&self, _param: NodeParam) -> bool

Applies param to this node in place, returning whether it was taken.

impl RenderNodeCpu for GaussianBlurNode

fn process_cpu(&self, rgba: &mut [u8], w: u32, h: u32)

Process rgba in-place.
