How hard would it be to check the color of a few different spots of a picture?

A clean image is important for many different reasons. If you have thousands of pictures if can be hard to figure out what needs to be cleaned and what doesn't. Is there an easy way to check a pixel to see if it is pure white or not in php?

Wow! Interesting...

$width = imagesx($resource);
$height = imagesy($resource);


for($x = 0; $x < $width; $x++) {
for($y = 0; $y < $height; $y++) {
// pixel color at (x, y)
$color = imagecolorat($resource, $x, $y);
}
}
