PHP | Imagick setImageGravity() Function

The Imagick::setImageGravity() function is an inbuilt function in PHP which is used to set the gravity property of an image. Difference between setGravity() and setImageGravity() is that the former applies for the whole Imagick object whereas the latter sets the gravity of the current image (in case of multiple images) in the sequence. Syntax:

bool Imagick::setImageGravity( int $gravity )

Parameters: This function accepts single parameter $gravity which holds an integer value. List of GRAVITY constants are given below:

• imagick::GRAVITY_NORTHWEST (0)
• imagick::GRAVITY_NORTH (1)
• imagick::GRAVITY_NORTHEAST (2)
• imagick::GRAVITY_WEST (3)
• imagick::GRAVITY_CENTER (4)
• imagick::GRAVITY_EAST (5)
• imagick::GRAVITY_SOUTHWEST (6)
• imagick::GRAVITY_SOUTH (7)
