Struct PyColormap 

pub struct PyColormap {
    pub kind: ColormapKind,
    pub vmin: f64,
    pub vmax: f64,
    pub alpha: f64,
}

A colormap that maps scalar values in [0, 1] to RGBA colors.

Fields

kind: ColormapKind

The colormap kind.

vmin: f64

Minimum scalar value (maps to t=0).

vmax: f64

Maximum scalar value (maps to t=1).

alpha: f64

Alpha value for all colors (0=transparent, 1=opaque).

Implementations

impl PyColormap

pub fn new(kind: ColormapKind, vmin: f64, vmax: f64) -> Self

Create a new colormap with explicit range.

pub fn viridis() -> Self

Create a Viridis colormap over [0, 1].

pub fn plasma() -> Self

Create a Plasma colormap over [0, 1].

pub fn jet() -> Self

Create a Jet colormap over [0, 1].

pub fn normalize(&self, value: f64) -> f64

Normalize a raw scalar value to t ∈ [0, 1].

pub fn map_value(&self, t: f64) -> [f64; 4]

Map a normalized value t ∈ [0, 1] to RGBA [r, g, b, a].

pub fn map_scalar(&self, value: f64) -> [f64; 4]

Map a raw scalar value directly.
