BRESENHAM'S LINE DRAWING ALGORITHM...

Bresenham’s Line Algorithm :

Ø  Read (Xa , Ya) and (Xb , Yb)

      dY = Yb – Ya

      dX = Xb – Xa

      P = 2dY – dX

      X = Xa, Y = Ya

Ø  While(X <= Xb)

      {

              plotpoint(X,Y)

              X++

              if(P<0)

              P=P + 2dY

              else

              {

                      Y++

                      P = P+2(dY - dX)

              }

         }

Ø     End
