Module blend_kernel 

GPU blend kernels (CPU simulation via Rayon).

Provides parallel image compositing and blending operations that simulate GPU compute-shader dispatch semantics.

Supported blend modes

Mode	Description
BlendMode::AlphaComposite	Porter-Duff “over” compositing
BlendMode::Additive	src + dst, clamped to 255
BlendMode::Multiply	src * dst / 255
BlendMode::Screen	1 - (1-src)*(1-dst)
BlendMode::Overlay	Photoshop-style overlay
BlendMode::SoftLight	Pegtop soft light formula
BlendMode::Difference	abs(src - dst)
BlendMode::Dissolve	Random per-pixel src/dst selection by opacity

Example

use oximedia_gpu::blend_kernel::{BlendKernel, BlendMode};

let src = vec![200u8, 100, 50, 255];   // opaque orange
let mut dst = vec![0u8, 128, 255, 255]; // opaque blue
BlendKernel::blend(&src, &mut dst, 1, 1, BlendMode::AlphaComposite, 255)
    .expect("blend failed");
