@unpic/pixels

ascorbic/get-pixels

Load and decode the pixels for a PNG or JPEG image in Node

This module will take the raw data or URL of a PNG or JPEG image and return the decoded pixels and dimensions of the image.

Installation

Install the module from npm.

Terminal window
npm install @unpic/pixels

Usage

import { getPixels } from "@unpic/pixels";


// From a URL
const { width, height, data } = await getPixels(
  "http://placekitten.com/100/100",
);


// From a file


const file = await fs.readFile("kitten.png");


const { width, height, data } = await getPixels(file);

There is also a getFormat function that will return the format of the image data. This is detected by the first magic bytes at the start of the data.

import { getFormat } from "@unpic/pixels";


const file = await fs.readFile("kitten.png");
const format = getFormat(file);
// format === "png"
