Module photon_rs::colour_spaces

Mix image with a single color, supporting passing opacity. The algorithm comes from Jimp. See function mix and function colorFn at following link: https://github.com/oliver-moran/jimp/blob/29679faa597228ff2f20d34c5758e4d2257065a3/packages/plugin-color/src/index.js Specifically, result_value = (mix_color_value - origin_value) * opacity + origin_value = mix_color_value * opacity + (1 - opacity) * origin_value for each of RGB channel.

__wasm_bindgen_generated_saturate_hsl

Increase the image’s saturation by converting each pixel’s colour to the HSL colour space and increasing the colour’s saturation.

__wasm_bindgen_generated_saturate_hsluv

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

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