Struct ColorInterpolator 

pub struct ColorInterpolator;

Interpolates Color values per ARGB channel.

Implementations

impl ColorInterpolator

pub fn lerp_rgb(to: Color, from: Color, progress: f32) -> Color

Interpolates each of the alpha, red, green and blue channels linearly.

impl ColorInterpolator

pub fn instance() -> &'static ColorInterpolator

The shared instance.

impl ColorInterpolator

pub fn lerp_hsl(from: Color, to: Color, progress: f32) -> Color

Interpolates in the HSL colour space, giving from at progress 0 and to at progress 1 (the expression function ColorLerpHSL and the Hsl colour space of a colour animation). Saturation, lightness and alpha are interpolated linearly; the hue takes the shorter way around the colour wheel, and the hue of an achromatic colour (black, white, greys) is that of the other colour, so a grey turns into a colour without passing through other hues.

pub fn lerp_rgb_linear(from: Color, to: Color, progress: f32) -> Color

Interpolates the red, green and blue channels in linear light (the RgbLinear colour space): the channels are decoded with the sRGB transfer function, interpolated, and encoded again. Alpha is interpolated linearly.

pub fn lerp_hsl_linear(from: Color, to: Color, progress: f32) -> Color

Interpolates in the HSL colour space of the linear-light colour (the HslLinear colour space): the channels are decoded with the sRGB transfer function, the colour is interpolated in HSL as lerp_hsl does, and the result is encoded again.
