We present a special two-energy-two-angle amplitude which can be rigorously derived for the pion-proton bremsstrahlung ({pi}{sup +}{ital p}{gamma}) process near the {Delta}{sup ++}(1232) resonance and report the magnetic dipole moment of the {Delta}{sup ++},{mu}{sub {Delta}}, extracted from existing data. The extracted value of {mu}{sub {Delta}} are 3.7--4.2 {ital e}/2{ital m}{sub {ital p}} from one set of data and 4.6--4.9 {ital e}/2{ital m}{sub {ital p}} from another. Here, {ital m}{sub {ital p}} is the proton mass. The overall agreement between the theortical predictions calculated with the extracted {mu}{sub {Delta}} and the experimental measurements is excellent.
