Color-convert is a color conversion library for JavaScript and node.
|
||
|
|
It converts all ways between `rgb`, `hsl`, `hsv`, `hwb`, `cmyk`, `ansi`, `ansi16`, `hex` strings, and CSS `keyword`s (will round to closest):
|
||
|
|
|
||
|
|
```js
|
||
|
|
var convert = require('color-convert');
|
||
|
|
|
||
|
|
convert.rgb.hsl(140, 200, 100); // [96, 48, 59]
|
||
|
|
convert.keyword.rgb('blue'); // [0, 0, 255]
|
||
|
|
|
||
|
|
var rgbChannels = convert.rgb.channels; // 3
|
||
|
|
var cmykChannels = convert.cmyk.channels; // 4
|
||
|
|
var ansiChannels = convert.ansi16.channels; // 1
|
||
|
|
```
|
||
|
|
|
||
|
|
# Install
|
||
|
|
|
||
|
|
```console
|
||
|
|
$ npm install color-convert
|
||
|
|
```
|
||
|
|
|
||
|
|
# API
|
||
|
|
|
||
|
|
Simply get the property of the _from_ and _to_ conversion that you're looking for.
|
||
|
|
|
||
|
|
All functions have a rounded and unrounded variant. By default, return values are rounded. To get the unrounded (raw) results, simply tack on `.raw` to the function.
|
||
|
|
|
||
|
|
All 'from' functions have a hidden property called `.channels` that indicates the number of channels the function expects (not including alpha).
|
||
|
|
|
||
|
|
```js
|
||
|
|
var convert = require('color-convert');
|
||
|
|
|
||
|
|
// Hex to LAB
|
||
|
|
convert.hex.lab('DEADBF'); // [ 76, 21, -2 ]
|
||
|
|
convert.hex.lab.raw('DEADBF'); // [ 75.56213190997677, 20.653827952644754, -2.290532499330533 ]
|
||
|
|
|
||
|
|
// RGB to CMYK
|
||
|
|
convert.rgb.cmyk(167, 255, 4); // [ 35, 0, 98, 0 ]
|
||
|
|
convert.rgb.cmyk.raw(167, 255, 4); // [ 34.509803921568626, 0, 98.43137254901961, 0 ]
|
||
|
|
```
|
||
|
|
|
||
|
|
### Arrays
|
||
|
|
All functions that accept multiple arguments also support passing an array.
|
||
|
|
|
||
|
|
Note that this does **not** apply to functions that convert from a color that only requires one value (e.g. `keyword`, `ansi256`, `hex`, etc.)
|
||
|
|
|
||
|
|
```js
|
||
|
|
var convert = require('color-convert');
|
||
|
|
|
||
|
|
convert.rgb.hex(123, 45, 67); // '7B2D43'
|
||
|
|
convert.rgb.hex([123, 45, 67]); // '7B2D43'
|
||
|
|
```
|
||
|
|
|
||
|
|
## Routing
|
||
|
|
|
||
|
|
Conversions that don't have an _explicitly_ defined conversion (in [conversions.js](conversions.js)), but can be converted by means of sub-conversions (e.g. XYZ -> **RGB** -> CMYK), are automatically routed together. This allows just about any color model supported by `color-convert` to be converted to any other model, so long as a sub-conversion path exists. This is also true for conversions requiring more than one step in between (e.g. LCH -> **LAB** -> **XYZ** -> **RGB** -> Hex).
|
||
|
|
|
||
|
|
Keep in mind that extensive conversions _may_ result in a loss of precision, and exist only to be complete. For a list of "direct" (single-step) conversions, see [conversions.js](conversions.js).
