procreate-swatches

Read and create Procreate .swatches palette files.

Usage

npm install procreate-swatches

import { readSwatchesFile, createSwatchesFile } from 'procreate-swatches';

// Node.js
import { promises as fs } from 'fs';
(async () => {
  const data = await fs.readFile('path/to/palette.swatches');
  const swatches = readSwatchesFile(data);
})();

// Browser
(async () => {
  const response = await fetch('path/to/palette.swatches');
  const data = await response.arrayBuffer();
  const swatches = readSwatchesFile(data);
})();

// Creating a .swatches file
(async () => {
  const swatchesFile = createSwatchesFile('My Palette', [
    ['rgb', [255,0,0]],
    ['rgb', [0,255,0]],
    ['rgb', [0,0,255]]
  ]);
  console.log(swatchesFile); // ArrayBuffer
})();

This module is also available as commonjs:

const { readSwatchesFile, createSwatchesFile } = require('procreate-swatches/cjs');

API

readSwatchesFile(data[, colorSpace = 'hsv'])

Reads the contents of a Procreate .swatches file and optionally converts the parsed colors to a different color space.

Arguments:

• data - required, the file to be parsed. Supported formats: base64, text, binarystring, array, uint8array, arraybuffer, blob, nodebuffer
• colorSpace - string - optional, the color space to convert the parsed colors to, defaults to hsv. Procreate stores swatches in HSB (an alias of HSV), so if you leave the second argument blank they will stay that way. Supported color spaces: rgb, hsl, hsv, hwb, xyz, lab, lch.

Returns:

• object - a plain object containing two properties:
  • name - string - the name of the parsed palette
  • colors - array - containing colors from the palette as arrays in the format [[...colorValues], colorSpace], i.e. ['rgb', [255,255,255]]. Some elements of the colors array may be null, indicating an empty spot in the palette.

Throws:

• ProcreateSwatchesError - if the file is not a valid .swatches file, or if the requested color space is not supported

createSwatchesFile(name, colors, format = 'uint8array')

Creates a new Procreate .swatches file.

Arguments:

• name - string - the name of the palette
• colors - array - containing the colors to be included in the palette, in the format [colorSpace, [...colorValues]], i.e. ['rgb', [255,255,255]] (spaces other than hsv will be converted). You may also include null to create an empty spot in the palette. A Procreate palette may only contain 30 colors, any more will be ignored.
• format - string - the format to return the created file in. Supported formats: base64, text, binarystring, array, uint8array, arraybuffer, blob, nodebuffer

Returns:

• arraybuffer - raw contents of the created .swatches file

Throws:

• TypeError - if the provided name is not a string, or if colors are not an array following the format [[...colorValues], colorSpace]
• ProcreateSwatchesError - if the color space of a color is not supported, or if the color is not valid
