Module scale_kernel 

GPU scaling kernels (CPU simulation via Rayon).

Provides parallel image scaling operations that simulate GPU compute shader dispatch. Supports packed RGBA and planar YUV formats.

Supported filters

Filter	Quality	Speed
ScaleFilter::Nearest	Low	Fastest
ScaleFilter::Bilinear	Medium	Fast
ScaleFilter::Bicubic	High	Medium
ScaleFilter::Area	High (downscale)	Medium

Example

use oximedia_gpu::scale_kernel::{ScaleKernel, ScaleFilter};

let src = vec![0u8; 8 * 8 * 4]; // 8×8 RGBA
let mut dst = vec![0u8; 4 * 4 * 4]; // scale to 4×4
ScaleKernel::scale_rgba(&src, 8, 8, &mut dst, 4, 4, ScaleFilter::Bilinear)
    .expect("scale failed");

Structs
