NAME
rotate - Rotate, mirror, and transpose JPEG images (losslessly whenever
possible)
SYNOPSIS
rotate { options } file [ file ... ]
DESCRIPTION
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.

horizontal: Mirror image horizontally (left-right).
vertical : Mirror image vertically (top-bottom).
-r, -rotate, --rotate {90 | 180 | 270}
