       _P_r_o_t_a_t_e rotates a RADIANCE picture 90 degrees.  This is useful for out-
       put on hardcopy devices with aspect ratios opposite to the  input  pic-
       ture.   By  default, the image is rotated clockwise.  The _-_r option may
       be used to rotate the image counter-clockwise instead.

       The _-_c option indicates that the action is to correct an improper orig-
       inal  image orientation, thus the recorded scanline ordering should not
       be changed.

NNOOTTEESS
       To rotate an image 180 degrees, use _p_f_l_i_p_(_1_) with both the  _-_h  and  _-_v
       options.
