Function photon::colour_spaces::hsl

pub fn hsl(photon_image: &mut PhotonImage, mode: &str, amt: f32)

Image manipulation effects in the HSL colour space.

Effects include:

• saturate - Saturation increase.
• desaturate - Desaturate the image.
• shift_hue - Hue rotation by a specified number of degrees.
• darken - Decrease the brightness.
• lighten - Increase the brightness.

Arguments

• photon_image - A PhotonImage.
• mode - The effect desired to be applied. Choose from: saturate, desaturate, shift_hue, darken, lighten
• amt - A float value from 0 to 1 which represents the amount the effect should be increased by.

Example

// For example to increase the saturation by 10%:
use photon::color_spaces::hsl;
 
// Open the image. A PhotonImage is returned.
let img: PhotonImage = open_image("images/flowers.PNG");
 
hsl(&mut img, "saturate", 0.1);
