Lets say you want to reduce the resolution of uploaded images for the web.
The following will load a image at whatever resolution and resample it down to 72 dpi and save as a
different file.
The dpi for setImageResolution() and resampleImage() should be whatever dpi your resampling too.
<?php
$image = new Imagick();
$image->readImage('image.jpg');
$image->setImageResolution(72,72);
$image->resampleImage(72,72,imagick::FILTER_UNDEFINED,0);
$image->writeImage('image72.jpg');
?>
