Struct ScaleNode 

pub struct ScaleNode {
    pub width: u32,
    pub height: u32,
    pub algorithm: ScaleAlgorithm,
    /* private fields */
}

Resample a frame to a target resolution.

In Phase 1 the GPU path renders into the output texture at whatever size it was allocated — the graph allocates same-size textures, so ScaleNode acts as a bilinear blit pass. Full dimension-changing support (variable output texture size) is a Phase 2 addition.

The CPU path is a no-op; use an offline scaler (e.g. image crate) for CPU-side resizing.

Fields

width: u32

Target width in pixels (used as metadata; output size depends on the graph).

height: u32

Target height in pixels.

algorithm: ScaleAlgorithm

Sampling algorithm.

Implementations

impl ScaleNode

pub fn new(width: u32, height: u32, algorithm: ScaleAlgorithm) -> Self

Trait Implementations

impl Default for ScaleNode

fn default() -> Self

Returns the “default value” for a type.

impl RenderNode for ScaleNode

Available on crate feature wgpu only.

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 pass_count(&self) -> usize

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

impl RenderNodeCpu for ScaleNode

fn process_cpu(&self, _rgba: &mut [u8], _w: u32, _h: u32)

Process rgba in-place.
