Function trk_io::orientation::inverse_orientations_affine

pub fn inverse_orientations_affine(
    orientations: &Orientations,
    dim: [i16; 3]
) -> Affine4

Affine transform reversing transforms implied in orientations

Imagine you have an array arr of shape shape, and you apply the transforms implied by orientations, to get tarr. tarr may have a different shape shape_prime. This routine returns the affine that will take an array coordinate for tarr and give you the corresponding array coordinate in arr.
