Invalid file signature error when using buffer from nut.js

[KolbySisk]

Hi all,

I'm utilizing nut.js in my project to capture the screen. I want to give the buffer from that operation to get-pixels. When I do though, I get this error:

Error: Invalid file signature
    at module.exports.Parser._parseSignature (/private/tmp/o/node_modules/get-pixels/node_modules/pngjs/lib/parser.js:53:18)

    at getPixels (/private/tmp/o/node_modules/get-pixels/node-pixels.js:140:5) undefined

This is my code:

const { screen } = require("@nut-tree/nut-js");
const getPixels = require("get-pixels");

(async () => {
  const screenCapture = await screen.grab();
  getPixels(screenCapture.data, 'image/png', async (error, pixels) => {
      console.log(error, pixels)
    });
})();

screenCapture.data is an image buffer, which when console logged looks like:

<Buffer d5 86 f5 ff d4 86 f5 ff d4 86 f5 ff d4 86 f5 ff d4 86 f5 ff d5 86 f5 ff d4 86 f5 ff d4 86 f5 ff d4 86 f5 ff d4 86 f5 ff d4 86 f6 ff d5 87 f5 ff d4 87 ... 8294350 more bytes>

Does anyone have any advice on how to make this work, or am I running into a bug? Thanks.
