    I would suggest to use imagecolorat:

    
$img_ar = array();
$im = imagecreatefromjpeg('/path/to/image.jpg');
if (! $im) die("cant load image");
for ($x=0; $x<imagesx($im); $x++) {
  for ($y=0; $y<imagesy($im); $y++) {
    $img_ar[$x][$y] = imagecolorat($im, $x, $y);
  }
}

// process $img_ar
    Code (markup):
    But probably it is better to use imagecolorat directly.
