Struct CrossfadeNode 

pub struct CrossfadeNode {
    pub factor: f32,
    pub to_rgba: Vec<u8>,
    pub to_width: u32,
    pub to_height: u32,
}

Linear crossfade between two RGBA frames.

• factor = 0.0 → output equals the input frame (inputs[0] / process_cpu argument).
• factor = 1.0 → output equals to_rgba.
• factor = 0.5 → arithmetic mean of both frames.

The “to” frame is stored in the node at construction time.

Fields

factor: f32

Blend factor: 0.0 (from) → 1.0 (to).

to_rgba: Vec<u8>

The “to” frame as RGBA bytes. Length must equal to_width × to_height × 4.

to_width: u32

Width of to_rgba.

to_height: u32

Height of to_rgba.

Implementations

impl CrossfadeNode

pub fn new(factor: f32, to_rgba: Vec<u8>, to_width: u32, to_height: u32) -> Self

Construct a crossfade node.

to_rgba is the “to” frame (second input). It must be to_width × to_height × 4 bytes of RGBA data.

Trait Implementations

impl RenderNodeCpu for CrossfadeNode

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

Process rgba in-place.
