Installation

npm install maptoimage

Usage

const { mapToImage } = require("maptoimage");
const fs = require("fs");

(async () => {
	const img = mapToImage({
		"image": {
			"dimensions": {
				"width": 1280,
				"height": 720
			}
		},
		"map": {
			"center": {
				"lat": 39.67321,
				"lng": -104.95140
			},
			"zoom": 5,
			"layers": [
				"https://tile.openstreetmap.org/{z}/{x}/{y}.png",
				// https://mesonet.agron.iastate.edu/GIS/ridge.phtml
				"https://mesonet.agron.iastate.edu/cache/tile.py/1.0.0/ridge::USCOMP-N0Q-0/{z}/{x}/{y}.png",
				async (z, x, y) => {
					const buffer = await fs.promises.readFile("tile.png");
					return buffer;
				}
			]
		}
	});
	fs.writeFileSync("map.png", img.png().toBuffer());
})();
