functional-paint
This is a JavaScript library for manipulating image buffers with pure functions. It's not the most efficient way of doing this, and you probably won't be able to use this library in a performance-critical project. It's just for practicing image processing algorithms and functional programming.
Installation
This module is distributed via npm:
npm install functional-paint
Usage
import FunPaint from 'functional-paint';
const canvas = FunPaint.createImageBuffer(16, 16);
const color = [0, 0, 0, 0];
FunPaint.drawRect(canvas, 16, true, 0, 0, 16, 16, color);
