Source

pub struct ColorGenerator { /* private fields */ }

Expand description

A type that can generate distinct 8-bit colors.

Implementations§

Source §

impl ColorGenerator

Source

pub fn from_state(state: [u16; 3], min_brightness: f32) -> Self

Create a new ColorGenerator with the given pre-chosen state.

The minimum brightness can be used to control the colour brightness (0.0 - 1.0). The default is 0.5.

Source

pub fn new() -> Self

Create a new ColorGenerator with the default state.
