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 memo-
	    rial_gc.hdr.

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

SEE ALSO
