Hey. How can I use PHP to take an image and walk through each pixel? I would also like to know if it is possible to check the color of each pixel?
What are the tools for this?

Learn pixel color (0,0):
<?php $im = imagecreatefrompng("image.png"); $rgb = imagecolorat($im, 0, 0); $colors = imagecolorsforindex($im, $rgb); var_dump($colors); ?> Manual: http://php.net/manual/ru/function.imagecolorat.php http://php.net/manual/ru/function.imagecolorsforindex.php

It is possible through GD2 (as in the next answer), but it is possible through ImageMagick
<?php $image = new Imagick('testimage.jpg'); $x = 1; $y = 1; $pixel = $image->getImagePixelColor($x, $y); ?>
