# Quantize

🎨 Simple color palette quantization using MMCQ

## Installing

You can fetch this library by running the following

    go get -u github.com/joshdk/quantize

## Usage

```go

import (

	"image/color"

	"image/jpeg"

	"net/http"

	"github.com/joshdk/preview"

	"github.com/joshdk/quantize"

)

// Fetch the source image

resp, err := http.Get("https://blog.golang.org/gopher/plush.jpg")

if err != nil {

	panic(err.Error())

}

// Decode jpeg contents

img, err := jpeg.Decode(resp.Body)

if err != nil {

	panic(err.Error())

}

// Reduce image into a palette of 8 colors

colors := quantize.Image(img, 3)

palette := make([]color.Color, len(colors))

for index, clr := range colors {

	palette[index] = clr

}

// Display our new palette

preview.Show(palette)

```

As an example, we can reduce a photo of the Go Gopher ([source](https://blog.golang.org/gopher)) into a color palette.
