An energy-dependent amplitude analysis of {pi}{sup {plus_minus}}-{sup 12}C elastic-scattering data in the pion energy range from 486 to 870 MeV was carried out. Using a careful treatment of Coulomb effects to describe the Coulomb nuclear interference together with the constraints from the {pi}{sup {plus_minus}}-{sup 12}C forward amplitude f{sub 0} by dispersion relations allows a stringent consistency check of the data. In general a satisfactory description of the data was achieved, but recent {pi}{sup {minus}}-{sup 12}C elastic-scattering data need considerable normalization factors to fit into the framework. The still not measured {pi}{sup +}-{sup 12}C data as well as the {pi}{sup {plus_minus}}-{sup 12}C data at 870 MeV are predicted. Phase shifts are calculated by partial wave projection of the amplitudes. The partial waves are summed up to obtain the total, total-elastic and total-inelastic cross sections. {copyright} {ital 1997} {ital The American Physical Society}
