fp-z Focal Point Zoom

The zoom or z-dimension value of a focal point of an image. Must be a float between 1 and 100, inclusive. The default value is 1, representing the original size of the image, and every full step is the equivalent of a 100% zoom (e.g. fp-z=2 is the same as viewing the image at 200%). The suggested range is 1–10. For the focal point to be set on an image, fit=crop and crop=focalpoint must be set as well.
