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.
