       This is a utility program to get and set the Exif Orientation Tag.  It can be used together with jpegtran
       in scripts for automatic orientation correction of digital camera pictures.

       The  Exif  orientation value gives the orientation of the camera relative to the scene when the image was
       captured.  The relation of the '0th row' and '0th column' to visual position is shown as below.

              Value | 0th Row     | 0th Column
              ------+-------------+-----------
                1   | top         | left side
                2   | top         | right side
                3   | bottom      | right side
                4   | bottom      | left side
                5   | left side   | top
                6   | right side  | top
                7   | right side  | bottom
                8   | left side   | bottom

       For convenience, here is what the letter F would look like if it were tagged correctly and displayed by a
       program that ignores the orientation tag:

       jpegexiforient output the Exif Orientation Tag in a JPEG Exif file.  With the options -1 ..  -8,  it  can
       also be used to set the tag.
