    You should use the PHP Imagick constants to correctly set the Image Units, as described here:

    http://www.php.net/manual/en/imagick.constants.php

    RESOLUTION constants

    imagick::RESOLUTION_UNDEFINED (integer)
    imagick::RESOLUTION_PIXELSPERINCH (integer)
    imagick::RESOLUTION_PIXELSPERCENTIMETER (integer)
