Below programs illustrate the Imagick::getGravity() function in PHP:
Program 1:
<?php // Create a new imagick object $imagick = new Imagick(); // Get the Gravity $gravity = $imagick->getGravity(); echo $gravity; ?> |
Output:
0 // Which means gravity is not set.
Program 2:
<?php // Create a new imagick object $imagick = new Imagick( // Set the Gravity $imagick->setGravity(3); // Get the Gravity $gravity = $imagick->getGravity(); echo $gravity; ?> |
Output:
3 // Which corresponds to imagick::GRAVITY_NORTHEAST.
