React Chameleon

React-chameleon is a HOC. With react-chameleon you can parse image colors and apply them how you want.


npm i react-chameleon


import React from 'react';
import ReactDOM from 'react-dom';
import Chameleon from 'react-chameleon';
const Text = props => {
    const {
        reactChameleonColors = []
    } = props;
    const defaultColors = {
        back: { r: 255, g: 255, b: 255, alpha: 1 },
        front: { r: 0, g: 0, b: 0, alpha: 1 }
    const [ 
        backColor = defaultColors.back,
        frontColor = defaultColors.front
    ] = reactChameleonColors;
    const getColor = c => `rgba(${c.r},${c.g},${c.b},${c.alpha})`;
    return <p
            backgroundColor: getColor(backColor),
            color: getColor(frontColor)
const ChameleonText = Chameleon(Text);

Name Type Required Default Description
img String Yes null Path to image. For example, './my/image/path.png'.
colorsCacheLimit Number No 100 In order not to do the same thing several times (image analysis), we cache the resulting colors for the images. Enter the number of entries in the cache here. The uniqueness of the set is determined by the settings.
adaptFrontColorsToBack Boolean No false Adapt the colors to the background color. The background color will be the first color after sorting, the other colors will adapt to it.
sortType String No 'count' What color characteristic will be used for sorting. Allowed values: "count", "alpha".
sortDir String No 'desc' Sorting direction. Allowed values: "desc", "asc".
colorsCount Number No undefined The number of colors used. It is necessary to specify to optimize the process of adapting colors to the background color.
colorDifference Number No 120 The minimum allowed difference in colors. For example, if we compare colors: rgb(0, 0, 0) and rgb(255, 255, 255), then "color_difference" of them is 765. Math.abs(0 - 255 + 0 - 255 + 0 - 255) = 765.
minColorAlpha Number No 0 The minimum acceptable alpha-channel level of color. All colors whose level will be lower will be ignored.
colorAlphaPrecision Number No 100 Precision of alpha-chanel value. For example, with a default value of 100, the precision will be 0.01.
