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

pub extern "C" fn __wasm_bindgen_generated_desaturate_hsl(
    arg0: <PhotonImage as RefMutFromWasmAbi>::Abi, 
    arg1: <f32 as FromWasmAbi>::Abi
) -> <() as ReturnWasmAbi>::Abi

Desaturate the image by a specified amount in the HSL colour space.

Arguments

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

Example

// For example to desaturate an image by 10% in the LCh colour space:
use photon::color_spaces::desaturate_hsl;
 
// Open the image. A PhotonImage is returned.
let img: PhotonImage = open_image("images/flowers.PNG");
 
desaturate_hsl(&mut img, 0.1);
