Struct BlendOps 

pub struct BlendOps<S: SimdOps> { /* private fields */ }

Blending operations using SIMD.

Implementations

impl<S: SimdOps> BlendOps<S>

pub const fn new(simd: S) -> Self

Create a new blending operations instance.

pub const fn simd(&self) -> &S

Get the underlying SIMD implementation.

pub fn lerp_u8(&self, a: u8, b: u8, weight: u8) -> u8

Linear interpolation between two values.

Returns: a + (b - a) * weight / 256

Weight is in range [0, 256] where:

• 0 = 100% a
• 256 = 100% b
• 128 = 50% each

pub fn lerp_i16x8(&self, a: I16x8, b: I16x8, weight: i16) -> I16x8

Linear interpolation for i16x8 vectors.

Returns: a + (b - a) * weight / 256

pub fn weighted_avg_u8x16(&self, a: U8x16, b: U8x16, weight: u8) -> U8x16

Weighted average of two u8x16 vectors.

Returns: (a * (256 - weight) + b * weight + 128) / 256

pub fn bilinear_blend_u8( &self, tl: u8, tr: u8, bl: u8, br: u8, hweight: u8, vweight: u8, ) -> u8

Bilinear blend for motion compensation.

Blends 4 samples using horizontal and vertical weights. Used for sub-pixel motion estimation.

Layout:

tl --- tr
|      |
bl --- br

Returns: blend of all 4 based on (hweight, vweight)

pub fn bilinear_blend_row_8( &self, tl: &[u8], tr: &[u8], bl: &[u8], br: &[u8], hweight: u8, vweight: u8, dst: &mut [u8], )

Bilinear blend for a row of 8 pixels.

Takes 4 input rows and blends them bilinearly.

impl<S: SimdOps + SimdOpsExt> BlendOps<S>

pub fn bilinear_blend_row_8_simd( &self, tl: &[u8], tr: &[u8], bl: &[u8], br: &[u8], hweight: u8, vweight: u8, dst: &mut [u8], )

Bilinear blend using SIMD for a row of 8 pixels.

Trait Implementations

impl<S: SimdOps + Default> Default for BlendOps<S>

fn default() -> Self

Returns the “default value” for a type.
