Here goes an exaple how to resize GIF-s.



<?php

$imagick = new Imagick("original.gif");



$format = $imagick->getImageFormat();

if ($format == 'GIF') {

  $imagick = $imagick->coalesceImages();

  do {

     $imagick->resizeImage(120, 120, Imagick::FILTER_BOX, 1);

  } while ($imagick->nextImage());

  $imagick = $imagick->deconstructImages();

  $imagick->writeImages('new_120x120.gif', true);



  // can be added some more gifs

  $imagick = $imagick->coalesceImages();

  do {

     $imagick->resizeImage(100, 100, Imagick::FILTER_BOX, 1);

  } while ($imagick->nextImage());

  $imagick = $imagick->deconstructImages();

  $imagick->writeImages('new_100x100.gif', true);

}



$imagick->clear();

$imagick->destroy();

?>



You can use any resize method (resizeImage) with this example.



This example works fine with *imagick module version 2.2.1-dev*, but doesn't work correctly with *imagick module version 3.0.1*.
