NAME
orient.py - change the orientation of a digital camera image file
SYNOPSIS
orient.py
image-file
orient.py
[1-8]
image-file
DESCRIPTION
This is a small script for changing the orientation of certain types
of digital camera image files. The image data is not modified, but
rather the EXIF tags stored with the image are altered to reflect the
new orientation. For this reason only images with the correct types of
EXIF tags can be changed using this script.
When called with with a numeric argument from 1 to 8, the orientation
will be changed as described in the options section below. When called
with only a filename, the current orientation will be written to the
console (also as a number from 1 to 8).
If the image contains no EXIF information or if the EXIF information is not
of the correct type, an error will be displayed and this script will
exit immediately.
This script is provided with the image conversion and transformation
plugins for Konqueror. For a more general-purpose JPEG rotation/reflection
tool, see
jpegorient(1)
which is also a part of this same set of plugins.
This utility is part of the official KDE add-ons module.
OPTIONS
The possible orientations are represented by the numbers 1 to 8 as
follows.
1
No change of orientation.
3
Rotate by a half turn (i.e., 180 degrees).
5
Transpose image (i.e., reflect across the upper-left to lower-right
diagonal axis).
6
Rotate by 90 degrees clockwise.
7
Transverse transpose image (i.e., reflect across the upper-right to
lower-left diagonal axis).
8
Rotate by 270 degrees clockwise (i.e., 90 degrees counter-clockwise).
