Answer 1

You can take the screenshot and try the following.

<?php 
    $image = new Imagick('testimage.jpg'); 
    $x = 1;  
    $y = 1; 
    $pixel = $image->getImagePixelColor($x, $y); 
?> 

You can also check this Libraryphp docs for other options.

Answer 2

This task can be done using java.awt.Robot | I haven't tried any for PHP

Robot r = new Robot();
r.getPixelColor(923, 87);
