pfsrotate(1)		    General Commands Manual		  pfsrotate(1)

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.
