rotate - Rotate, mirror, and transpose JPEG images (losslessly whenever possible)

rotate is distributed as a component of jigl, written by Jason Paul <jigl@xome.net>.  Its project page is
       located at http://xome.net/projects/jigl/.

       This manual page was adapted from the program help text by Nicholas Breen <nbreen@ofb.net> for the Debian
       project (but may be used by others).

rotate is a convenience frontend to jpegtran, allowing JPEG images to be rotated, mirrored, or transposed
       in  several  ways.  These operations are conducted losslessly (i.e., no image recompression) and keep all
       EXIF metadata intact.

-f,-flip,--flip{horizontal|vertical}
              horizontal: Mirror image horizontally (left-right).
              vertical  : Mirror image vertically (top-bottom).

       -r,-rotate,--rotate{90|180|270}
              90 : Rotate image 90 degrees clockwise.
              180: Rotate image 180 degrees.
              270: Rotate image 270 degrees clockwise (or 90 ccw).

       -tp,-transpose,--transpose
              Transpose image (across UL-to-LR axis).

       -tv,-transverse,--transverse]
              Transverse transpose (across UR-to-LL axis).
