Package Exports
- colorscale-interpolate
- colorscale-interpolate/dist/index.js
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (colorscale-interpolate) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
Color Scale Interpolate
Takes a color scale such as the legend of a heat map and allows calculating the color at any point along the scale.
Usage
import { ColorScale, interpolateColorScale } from "colorscale-interpolate";
const scale: ColorScale = [
{ color: "#FFFFFF", opacity: 1, threshold: 0.0 },
{ color: "#EEEEEE", opacity: 0.9, threshold: 0.1 },
{ color: "#DDDDDD", opacity: 0.8, threshold: 0.2 },
{ color: "#CCCCCC", opacity: 0.7, threshold: 0.3 },
{ color: "#BBBBBB", opacity: 0.6, threshold: 0.4 },
{ color: "#AAAAAA", opacity: 0.5, threshold: 0.5 },
{ color: "#999999", opacity: 0.4, threshold: 0.6 },
{ color: "#888888", opacity: 0.3, threshold: 0.7 },
{ color: "#777777", opacity: 0.2, threshold: 0.8 },
{ color: "#666666", opacity: 0.1, threshold: 0.9 },
{ color: "#555555", opacity: 0, threshold: 1.0 },
];
const colorValue = interpolateColorScale(scale, 0.55); // { color: '#a2a2a2', opacity: 0.45 }
