Here's a example of this function:





<?php


  $img = new Imagick();


  $img->readImage($image_file_name);


  // leave hue at 100%, drop saturation by 100%, leave brightness at 100%


  $img->modulateImage(100, 0, 100); 


  $img->writeImage($thumb_file_name);


  $img->clear();


  $img->destroy();


?>
