<entry>Rotates the image by specified angle. Common angles are 90,
|
||||||
|
270 and 180. Rotating the image to 90 and 270 will reverse the height
|
||||||
|
and width of the display window. It is necessary to set the new height and
|
||||||
|
width of the picture using the &VIDIOC-S-FMT; ioctl according to
|
||||||
|
the rotation angle selected.</entry>
