protate

PROTATE(1)						      General Commands Manual							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 output 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 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.
