NAME

       protate - rotate a RADIANCE picture.

SYNOPSIS

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

DESCRIPTION

       Protate rotates a RADIANCE picture 90 degrees.  This is useful for output on hardcopy devices with aspect
       ratios opposite to the input picture.  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 original 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.
