If ImagickDraw::setGravity ( int $gravity ) has been set, e,g; with $gravity= imagick::GRAVITY_CENTER.

Then, the x and y values offset the text from where the gravity setting would have placed it.

If the example included: $draw->setGravity (Imagick::GRAVITY_CENTER);
$image->annotateImage($draw, 10, 45, 0, 'The quick brown fox jumps over the lazy dog');

The text would be rendered to the right 10px and down 45px from the center. 

Gravity constants are very useful as they can save having to calculate the placement of variable text strings and font sizes.
