NAME
       pfsrotate - Rotate images 90 degrees.

SYNOPSIS
       pfsrotate [--r] [--help]

DESCRIPTION
       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.

OPTIONS
       --r, -r

	      Rotate the image counter-clockwise instead of clockwise.

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

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

NOTES
       To  rotate  an  image 180 degrees, use pfsflip(1) with both the --h and
       --v options specified.
