Face hide

Crops out the topmost part of an image if it contains a face.

func=facehide

If no faces are found or the image is too small for the face to be cropped out, a standard crop operation will be performed.

Face crop margins

To control the margin when cropping the face out, you can use the face_margin=Y operation. Y is in percent of the face height. Default value is 20. You can also use negative numbers if you would like to crop out only part of the face.
