Extract palette from pixels array, return pixels mapped to palette. Useful for organizing [palette-based encoding](https://ghub.io/image-encode), like GIF, or various limited colors renderers, like [gl-scatter2d](https://ghub.io/gl-scatter2d).

|
[](http://npmjs.org/package/image-palette)
|
|
|
|
```javascript
|
|
var palette = require('image-palette')
|
|
var pixels = require('image-pixels')
|
|
|
|
var {ids, colors} = palette(await pixels('./image.png'))
|
|
```
|
|
|
|
## API
|
|
|
|
### `var {ids, colors, amount} = palette(pixels, count=5)`
|
|
|
|
Extract palette from the input `pixels` array with `rgba` pixels sequence, whether flat or nested.
|
|
|
|
* `colors` is a list of extracted colors `[[r, g, b, a], [r, g, b, a], ...]`.
|
|
* `ids` is an array of input pixels mapped to extracted `colors`.
|
|
* `amount` is an array with amounts corresponding to the extracted colors, from `0..1` range.
|
|
* `count` is max number of colors to extract.
