inku
An RGBA Color
backed by a u32
.
Examples
type RGBA = inku::Color<inku::RGBA>;
let color = RGBA::new(0x000000ff);
let new_color = color
// Lighten the color by 10%
.lighten(0.1)
// Saturate the color by 30%
.saturate(0.3);
assert_eq!(new_color.to_u32(), 0x201111ff);
// 4 bytes
assert_eq!(4, std::mem::size_of::<RGBA>());
Storage Formats
An RGBA color backed by a u32
.
There are multiple storage formats to choose from, ZRGB
and RGBA
. These determine how
the underlying u32
is laid out.
type RGBA = inku::Color<inku::RGBA>;
type ZRGB = inku::Color<inku::ZRGB>;
assert_eq!(RGBA::new(0xfacadeff).to_u32(), 0xfacadeff);
// NOTE: The high byte is zeroed out
assert_eq!(ZRGB::new(0xfffacade).to_u32(), 0x00facade);
Manipulations are lossy
Because we're representing the colour with a u32
, manipulations are not reversible.
Consider the following:
type RGBA = inku::Color<inku::RGBA>;
let color = RGBA::new(0xfacadeff);
// We convert the RGB values to HSL and desaturated the color
let desaturated_color = color.desaturate(0.1);
assert_eq!(0xf7ccdeff, desaturated_color.to_u32());
// We don't know what our original hue was, so we can't get back to the original color
let resaturated_color = desaturated_color.saturate(0.1);
assert_eq!(0xf9c9ddff, resaturated_color.to_u32());
