NAME

protate - rotate a RADIANCE picture.

SYNOPSIS

protate [ -c ] input [ output ]

DESCRIPTION

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.

EXAMPLES

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
