Struct ContinuousColorScale 

pub struct ContinuousColorScale { /* private fields */ }

A continuous color scale that linearly interpolates between color stops.

Unlike DiscreteColorScale, this scale produces smooth color gradients between control points. This is useful for products where smooth transitions are more informative than discrete steps.

Example

use nexrad_render::{ColorStop, ContinuousColorScale, Color};

let scale = ContinuousColorScale::new(vec![
    ColorStop::new(0.0, Color::rgb(0.0, 0.0, 1.0)),   // Blue at 0
    ColorStop::new(50.0, Color::rgb(0.0, 1.0, 0.0)),  // Green at 50
    ColorStop::new(100.0, Color::rgb(1.0, 0.0, 0.0)), // Red at 100
]);

// Value 25 produces a blue-green blend
let color = scale.color(25.0);

Implementations

impl ContinuousColorScale

pub fn new(stops: Vec<ColorStop>) -> Self

Creates a new continuous color scale from color stops.

Stops are automatically sorted by value (lowest to highest).

pub fn color(&self, value: f32) -> Color

Returns the linearly interpolated color for the given value.

Values below the lowest stop get the lowest stop’s color. Values above the highest stop get the highest stop’s color.

pub fn stops(&self) -> &[ColorStop]

Returns the stops in this color scale (sorted lowest to highest).
