protate - rotate a RADIANCE picture. |
protate [ -c ][ -r ] input [ output ] |
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. |
To rotate an image 180 degrees, use pflip(1) with both the -h and -v options. |
