.SH DESCRIPTION |
| 17 |
.I Protate |
| 18 |
rotates a RADIANCE picture 90 degrees. |
| 19 |
This is useful for output on hardcopy devices with aspect ratios opposite |
| 20 |
to the input picture. |
| 21 |
By default, the image is rotated clockwise. |
| 22 |
The |
| 23 |
.I \-r |
| 24 |
option may be used to rotate the image counter-clockwise instead. |
| 25 |
.PP |
| 26 |
The |
| 27 |
.I \-c |
| 28 |
option indicates that the action is to correct an improper original |
| 29 |
image orientation, thus the recorded scanline ordering should not |
| 30 |
be changed. |
| 31 |
.SH NOTES |
| 32 |
To rotate an image 180 degrees, use |
| 33 |
.I pflip(1) |
| 34 |
with both the |
| 35 |
.I -h |
| 36 |
and |
| 37 |
.I -v |
| 38 |
options. |
