Function saturate_lch 

pub fn saturate_lch(img: &mut PhotonImage, level: f32)

Increase the image’s saturation in the LCh colour space.

Arguments

• img - A PhotonImage.
• level - Float value from 0 to 1 representing the level to which to increase the saturation by. The level must be from 0 to 1 in floating-point, f32 format. Increasing saturation by 80% would be represented by a level of 0.8

Example

// For example to increase saturation by 40% in the Lch colour space:
use photon_rs::colour_spaces::saturate_lch;
use photon_rs::native::open_image;

// Open the image. A PhotonImage is returned.
let mut img = open_image("img.jpg").expect("File should open");
saturate_lch(&mut img, 0.4_f32);
