[SOLVED] Reading Pixels

[cs1h]

Hi,

 

Does anyone know a way to read each pixel from an image so that each individual pixel can be put through a program one at a time using php?

 

Thanks,

Something like this?

<?php
$image  = imagecreatefrompng("/path/to/file.png");
$width  = imagesx($image);
$height = imagesy($image);
for($y=0; $y<$height; $y++) {
    for($x=0; $x<$width; $x++) {
        $rgb = imagecolorat($image,$x,$y);
        echo "Pixel $x , $y colour: $rgb\n";
    }
}
?>
