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

It appears that the GRAVITY constants have an integer equivalent:
NORTHWEST = 1
NORTH = 2
NORTHEAST = 3
WEST = 4
CENTER = 5
EAST = 6
SOUTHWEST = 7
SOUTH = 8
SOUTHEAST = 9
