Google Lens For Ubuntu

For those who use Google Lens on Android as an OCR to capture text from images, screenshots, etc.. here is a bash script that does the same on Ubuntu.

Sometimes we need to copy a telephone number in an APP where there isn't a copy to clipboard feature enabled or maybe to copy texts from an picture.

This can be done with a OCR, this script does that allowing to drag&drop select a region of the screen and copy to clipboard the text parsed from the image.

#!/bin/bash

	'use strict';
	exports.handler = (event, context, callback) => {

	// Get request and request headers
	const request = event.Records[0].cf.request;
	const headers = request.headers;

	// Configure authentication
	const authUser = 'user';
	const authPass = 'pass';

	var ring = 1;
	var max = 9;
	while (max < location)
	{
	ring += 1;
	max += (((ring + 1) * 2) - 2) * 4;
