Example #1 ImagickPixelIterator::resetIterator()

`<?php
function resetIterator($imagePath) {
$imagick = new \Imagick(realpath($imagePath));
$imageIterator = $imagick->getPixelIterator();
/* Loop trough pixel rows */
foreach ($imageIterator as $pixels) {
/* Loop through the pixels in the row (columns) */
foreach ($pixels as $column => $pixel) {
/** @var $pixel \ImagickPixel */
if ($column % 2) {
/* Make every second pixel 25% red*/
$pixel->setColorValue(\Imagick::COLOR_RED, 64);
}
}
/* Sync the iterator, this is important to do on each iteration */
$imageIterator->syncIterator();
}
$imageIterator->resetiterator();
/* Loop trough pixel rows */
foreach ($imageIterator as $pixels) {
