count colours, pixel by pixel

 

<?php
$im = imagecreatefrompng('myfile.png');

$ccount = array();
for ($x=0, $w = imagesx($im); $x < $w; $x++)
{
    for ($y=0, $h = imagesy($im); $y < $h; $y++)
    {
        $c = imagecolorat($im, $x, $y);
        $a = imagecolorsforindex($im, $c);
        $ccount[vsprintf('%02X%02X%02X', $a)]++;
    }
}
$max = max($ccount);
$sum = array_sum($ccount);
$mostused = array_search($max, $ccount);
$pcent = $max*100/$sum;
printf ('Most used #%s : %0.2f%%', $mostused, $pcent);
?>
