Struct GammaLut 

pub struct GammaLut { /* private fields */ }

Pre-computed gamma correction lookup table.

Caches the gamma curve for efficient repeated application. Use this when applying the same gamma to multiple images.

Example

let lut = GammaLut::new(2.2);
lut.apply(&mut image1);
lut.apply(&mut image2); // Reuses the same LUT

Implementations

impl GammaLut

pub fn new(gamma: f32) -> Self

Create a new gamma lookup table.

Arguments

• gamma - Gamma value (typically 2.2 for sRGB)

pub fn gamma(&self) -> f32

Get the gamma value this LUT was created with.

pub fn apply(&self, image: &mut RgbImage)

Apply gamma correction using the cached lookup table.
