List of GRAVITY constants are given below:
- imagick::GRAVITY_NORTHWEST (1)
- imagick::GRAVITY_NORTH (2)
- imagick::GRAVITY_NORTHEAST (3)
- imagick::GRAVITY_WEST (4)
- imagick::GRAVITY_CENTER (5)
- imagick::GRAVITY_EAST (6)

- imagick::GRAVITY_SOUTHEAST (9)
Below programs illustrate the ImagickDraw::getGravity() function in PHP:
Program 1:
<?php // Create a new ImagickDraw object $draw = new ImagickDraw(); // Get the font Gravity $Gravity = $draw->getGravity(); echo $Gravity; ?> |
Output:
0 // Which is the default value.
Program 2:
<?php // Create a new ImagickDraw object $draw = new ImagickDraw(); // Set the font Gravity $draw->setGravity(8); // Get the font Gravity $Gravity = $draw->getGravity(); echo $Gravity; ?> |
Output:
8
Program 3:
<?php // Create a new imagick object $imagick = new Imagick(); // Create a image on imagick object $imagick->newImage(800, 250, 'black'); // Create a new ImagickDraw object $draw = new ImagickDraw(); // Set the fill color $draw->setFillColor('cyan'); // Set the font size $draw->setFontSize(20); // Annotate a text to (50, 100) $draw->annotation(50, 100, 'The gravity here is ' . $draw->getGravity()); // Set the gravity $draw->setGravity(3); // Annotate a text to (50, 100) $draw->annotation(50, 100, 'The gravity here is ' . $draw->getGravity()); // Render the draw commands $imagick->drawImage($draw); // Show the output $imagick->setImageFormat('png'); header("Content-Type: image/png"); echo $imagick->getImageBlob(); ?> |
Output:
