Struct GradientColorMap 

pub struct GradientColorMap { /* private fields */ }

A color map built from sorted RGB stops, interpolated linearly in RGB space.

Implementations

impl GradientColorMap

pub fn new(stops: Vec<(f64, RGBColor)>) -> Self

Build from explicit (position, color) stops. Positions are clamped to [0, 1] and sorted; at least one stop is required (an empty list falls back to mid-gray).

pub fn color(&self, t: f64) -> RGBColor

The color at t (clamped to [0, 1]).

pub fn viridis() -> Self

The viridis perceptually-uniform sequential map (matplotlib).

pub fn magma() -> Self

The magma sequential map (matplotlib).

pub fn blues() -> Self

ColorBrewer sequential Blues.

pub fn reds() -> Self

ColorBrewer sequential Reds.

pub fn rd_bu() -> Self

ColorBrewer diverging RdBu (red → white → blue). Pairs with Normalization::Symmetric for correlation matrices.

pub fn coolwarm() -> Self

A blue → light → red diverging map (matplotlib coolwarm style).

pub fn grayscale() -> Self

Simple white → black grayscale.
