The broad X-ray iron line observed in many active galactic nuclei spectra is thought to originate from the accretion disc surrounding the central supermassive black hole. We show how to perform the analytic integration of the geodesic equations that describe the photon trajectories in the general case of a rotating black hole (Kerr metric) by using Jacobian elliptic functions. We present a fast and efficient numerical code for modelling emission line profiles from accretion discs. Applications to observed iron line profiles are presented.
