A method for studying continuum radiative transfer in the presence of the super-strong magnetic fields inferred to exist in the accretion columns of X-ray pulsars is described. Solution of the transfer equation involves convergent iteration of coupled Feautrier and moment equations including generalized Eddington factor moments of the scattering and absorption cross sections. The full angular dependence of the cross sections and emergent intensity, including azimuthal dependence, is included to allow for cases where the magnetic field is not normal to the surface of the plasma, modeled here as a series of one-dimensional slabs. The general solution technique applied to coherent scattering is described. Two benchmark calculations for uniform slabs with cold plasma coherent scattering are presented for comparison with previous studies.
