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 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. |
