protate - rotate a RADIANCE picture.
protate [ -c ] input [ output ]
Protate rotates a RADIANCE picture 90 degrees clockwise.
This is useful for output on hardcopy devices with aspect
ratios opposite to the input picture.
The -c option indicates that the action is to correct an
improper original image orientation, thus the recorded
scanline ordering should not be changed.
To rotate an image 90 degrees counterclockwise, use pflip(1)
first to rotate the image 180 degrees:
pflip -h -v input temp
protate temp output
rm temp
