@mapka/sprites-generate

This is fork of spritezero library. This is JS based solution using mapnik library for image generation.

Alternatively you can use spreet library which is written in Rust.

Usage

import { readFileSync, writeFileSync } from 'node:fs';
import { generateLayout, generateImage } from '@mapka/sprites-generate';

const layout = await generateLayout({
  imgs: [
    { svg: readFileSync('aerialway-24.svg'), id: 'aerialway-24' },
    { svg: readFileSync('aerialway-24-copy.svg'), id: 'aerialway-24-copy' },
    { svg: readFileSync('aerialway-24-alternate.svg'), id: 'aerialway-24-alternate' },
  ],
  pixelRatio: 2,
  format: false,
});

const spriteImage = await generateImage(layout);
writeFileSync('sprite.png', spriteImage);
