📜 SYNOPSIS

jpegexiforient [switches] jpegfile

📖 DESCRIPTION

This utility program reads and writes 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 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:
