Struct SharpenNode 

pub struct SharpenNode {
    pub radius: f32,
    pub strength: f32,
    /* private fields */
}

Unsharp-mask sharpen: orig + (orig - blurred) * strength.

Fields

radius: f32

Blur radius (as the Gaussian sigma) for the unsharp mask. Range [0.5, 5.0].

strength: f32

Sharpening strength (0.0 = no-op). Typical range [0.0, 3.0].

Implementations

impl SharpenNode

pub fn new(radius: f32, strength: f32) -> Self

Creates an unsharp-mask sharpen node.

Trait Implementations

impl RenderNode for SharpenNode

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 SharpenNode

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

Process rgba in-place.
