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



For example: 

$draw->setGravity (Imagick::GRAVITY_CENTER);

$image->annotateImage($draw, 0, 0, 0, 'The quick brown fox jumps over the lazy dog');



Will horizontally and vertically center the text string.



Note, there are several gravity constants available. See, Constants — Imagick class constants
