Radiance protate program

PROTATE(1)                                                          PROTATE(1)

NAME

       protate - rotate a RADIANCE picture.

SYNOPSIS

       protate [ -c ][ -r ] input [ output ]

DESCRIPTION

       Protate rotates a RADIANCE picture 90 degrees.  This is useful for out-
       put on hardcopy devices with aspect ratios opposite to the  input  pic-
       ture.   By  default, the image is rotated clockwise.  The -r option may
       be used to rotate the image counter-clockwise instead.

       The -c option indicates that the action is to correct an improper orig-
       inal  image orientation, thus the recorded scanline ordering should not
       be changed.

NOTES

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