Struct BlendModeNode 

pub struct BlendModeNode {
    pub mode: BlendMode,
    pub opacity: f32,
    pub overlay_rgba: Vec<u8>,
    pub overlay_width: u32,
    pub overlay_height: u32,
    /* private fields */
}

Apply a Photoshop-compatible blend mode to two input textures.

input_count() = 2 — inputs[0] is the base layer, inputs[1] is the overlay. The opacity field attenuates the overlay’s contribution.

For the CPU path the overlay data must be stored in overlay_rgba.

Fields

mode: BlendMode

Blend algorithm.

opacity: f32

Overlay opacity (0.0 = invisible, 1.0 = fully applied).

overlay_rgba: Vec<u8>

Overlay frame as RGBA bytes (required for CPU path).

overlay_width: u32

Width of overlay_rgba.

overlay_height: u32

Height of overlay_rgba.

Implementations

impl BlendModeNode

pub fn new( mode: BlendMode, opacity: f32, overlay_rgba: Vec<u8>, overlay_width: u32, overlay_height: u32, ) -> Self

Trait Implementations

impl RenderNode for BlendModeNode

Available on crate feature wgpu only.

fn input_count(&self) -> usize

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

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

Run the GPU render pass.

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 BlendModeNode

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

Process rgba in-place.
