Printful PNG

To use Printful with PNG images, you can utilize the fast-png library, which is a PNG image decoder and encoder written entirely in JavaScript.

Here's a brief snippet to get you started:

const fastPng = require('fast-png');

// Load or generate a PNG image
const pngImage = await fastPng.load('image.png');

// Encode the PNG image
const encodedImage = await fastPng.encode(pngImage, 100); // 100 is the quality level (0-100)

// Send the encoded image to Printful for printing

Note that you'll need to replace 'image.png' with your actual PNG image file path or generate a new PNG image using fast-png. Additionally, adjust the quality level (100) according to your needs.
