ix

The integer factor by which the image is decimated in x-dimension, i.e., every ix'th point is selected.(required)

iy

The integer factor by which the image is decimated in y-dimension.(optional: default=1)

iz

The integer factor by which the image is decimated in z-dimension.(optional: default=1)
