lens correction not working as expected

The following line does a slight zoom on the image

img = img.lens_corr(strength=1.0, zoom = 1.0)

this is not expected. With machine vision we would expect the zoom of 1.0 not to zoom at all. I am using the global shutter camera.


It could be a rounding issue, we use floats. The algorithm is based on this:

And this is our code:


Ok, thanks. I can work with that.
