Radiance protate program
PROTATE(1) 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 out-
put 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 orig-
inal 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.
