Documentation

Overview

Package gradient provides color gradient interpolation shared by the style and fx packages. It lives under internal/ so that fx subpackages can use gradient math without importing the style package.

Functions

func Interpolate

func Interpolate(t float64, stops []ColorStop) colorful.Color

Interpolate computes the color at position t (0.0-1.0) along the given gradient stops using CIE-LCh blending for perceptually uniform transitions. Edge cases: empty -> white, single stop -> that color, t outside range -> clamp to nearest stop.

Types

type ColorStop

type ColorStop struct {
	Position float64        // 0.0-1.0
	Color    colorful.Color // from github.com/lucasb-eyer/go-colorful
}

ColorStop defines a color at a specific position along a gradient. Position is in the range 0.0-1.0.
