    This method uses the ImageMagick "-density {$x_resolution}x{$y_resolution}" parameter

    Note that any changes to the resolution (-density option) must be made before specifying the file, so construct the object with no file path and then use $object->readImage('path/to/file'); otherwise the density won't change.
    Also see Imagick::setResolution.
