       Use  this  command  to  rotate images from a stream of pfs. This command is useful for output on hardcopy
       devices with aspect ratios opposite to the input image.  By default, the image is rotated clockwise.  The
       --r option may be used to rotate the image counter-clockwise instead.

       pfsin memorial.hdr | pfsrotate -r | pfsout memorial_gc.hdr

              Rotate memorial image 90 degrees counter-clockwise and save to memorial_gc.hdr.
