adobe-aco
Read and create Adobe .aco color swatches. Implemented according to official Adobe specs.
Usage
npm install adobe-acoCreate an .aco file
import { createAcoFile } from 'adobe-aco';
import { saveAs } from 'file-saver';
const myAcoFile = createAcoFile([
[[212, 30, 42], 'rgb', 'Hearty Red'],
[[255, 140, 203], 'rgb', 'Luscious Pink'],
[[40, 80, 148], 'rgb', 'Deep Navy'],
]);
saveAs(new Blob([myAcoFile]), 'MySwatches.aco')Read an .aco file
import { readAcoFile } from 'adobe-aco';
(async () => {
const myAcoFile = await fetch('MySwatches.aco').then(response => response.arrayBuffer());
const swatches = readAcoFile(myAcoFile);
console.log(swatches[0]); // [[212, 30, 42], 'rgb', 'Hearty Red']
console.log(swatches[1]); // [[255, 140, 203], 'rgb', 'Luscious Pink']
console.log(swatches[2]); // [[40, 80, 148], 'rgb', 'Deep Navy']
})();API
Types
Swatch-[number[], string, string]-[values, space, name]
createAcoFile(swatches: Swatch[], preserve = false): ArrayBuffer
Creates a new .aco file from the given swatches. Returns an ArrayBuffer;
By default, this function will assume that the swatches given to it are in standard ranges (i.e. 0÷255 for RGB, see Color ranges) and normalize them to the 16-bit integer range used by .aco files. Optionally you may pass true as the second argument to disable this behavior.
readAcoFile(data: ArrayBuffer, preserve = false): Swatch[]
Reads an .aco file, in the form of an ArrayBuffer. Returns an array of Swatches.
By default, this function will normalize the extracted colors to a standard range (i.e. 0÷255 for RGB, see Color ranges), as within .aco files they are stored as 16-bit integers. Optionally you may pass true as the second argument to disable this behavior.
Color ranges
If you're not planning on using the preserve option then you only need the Standardized range.
| Color space | Standardized range | .aco range |
|---|---|---|
| RGB | 0÷255 | 0÷65535 |
| HSB | 0÷360/0÷100 | 0÷65535 |
| CMYK | 0÷1 | 0÷65535 |
| LAB | 0÷100/-128÷127 | 0÷10000/-12800÷12700 |
| Grayscale | 0÷1 | 0÷10000 |
