[−][src]Function photon_rs::colour_spaces::saturate_hsv

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

Increase the image's saturation in the HSV colour space.

Arguments

  • img - A PhotonImage.
  • level - Float value from 0 to 1 representing the level by 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 30% in the HSV colour space:
use photon::color_spaces::saturate_hsv;
 
// Open the image. A PhotonImage is returned.
let img: PhotonImage = open_image("images/flowers.PNG");
 
saturate_hsv(&mut img, 0.3);
