The following programs illustrate the
Imagick::getImageGravity() functionin PHP:
Program 1:
// Create a new imagick object $imagick = new Imagick ( ’ https://media.engineerforengineer.org/wp-content/uploads/engineerforengineer-13.png ’ );
// Get gravity $gravity = $imagick -> getImageGravity(); echo $gravity ; ?> Output:0 // which corresponds to imagick::GRAVITY_NORTHWEST.
Program 2:
// Create new imagick object $imagick = new Imagick ( ’ https://media.engineerforengineer.org/wp-content/uploads/engineerforengineer-13.png ’ );
// Set gravity $imagick -> setImageGravity (4);
// Get gravity $gravity = $imagick -> getImageGravity(); echo $gravity ; ?> Output:4 // which corresponds to imagick::GRAVITY_CENTER.
