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 also be set.
