React-Color-Thief

🎨 A React component for grabbing the color palette from an image. See a Demo

It is based on Lokesh's color-thief.

How to use

可以把src/ColorThief.js文件拷贝到自己的项目下，直接使用。

Get the dominant color from an image

const colorThief = new ColorThief()
colorThief.getColor(imgDom) //需要在Image onload完成后调用
colorThief.getColorFromUrl(imgUrl).then(...) //异步方法，返回一个Promise

Build a color palette from an image

In this example, we build an 8 color palette.

const colorThief = new ColorThief()
colorThief.getPalette(imgDom, 8) //需要在Image onload完成后调用

ColorThief Methods

function	returns
getColor(imgDom[, quality])	[r, g, b]
getPalette(imgDom[, colorCount, quality])	[ [r, g, b], [r, g, b], ...]
getColorFromUrl(imgUrl[, quality])	[r, g, b]
getColorAsync(imgUrl[, quality])	[r, g, b]
convertColorRgb(rgbArray)	"rgb(r, g, b)"

colorCount determines the size of the palette, the number of colors returned. If not set, it defaults to 10.
quality is an optional argument. It needs to be an integer. 1 is the highest quality settings. 10 is the default. There is a trade-off between quality and speed. The bigger the number, the faster the palette generation but the greater the likelihood that colors will be missed.
