This will separate out the individual RGB channels and recombine them:



<?php

$im = new Imagick ("test.jpg");

$red = clone $im;

$red->separateImageChannel (imagick::CHANNEL_RED);

$green = clone $im;

$green->separateImageChannel (imagick::CHANNEL_GREEN);

$red->addImage ($green);

$green->destroy ();

$blue = clone $im;

$blue->separateImageChannel (imagick::CHANNEL_BLUE);

$red->addImage ($blue);

$blue->destroy();

$red->setFirstIterator ();

$im_new = $red->combineImages (imagick::CHANNEL_ALL);

$im_new->writeImage ("test_rebuilt.png");

echo "<img src=\"test_rebuilt.png\">\r\n";

?>
