man jpegorient (Commandes) - change the orientations of JPEG images
NAME
jpegorient - change the orientations of JPEG images
SYNOPSIS
jpegorient { -90 | -180 | -270 | -v | -h } image-file ...
DESCRIPTION
This is a simple utility for changing the orientations of one or more JPEG images. It is provided as part of the image conversion and transformation plugins for Konqueror.
A single option must be passed before any filenames to specify how the orientations of the images are to be changed. Each new image will be saved over the old one.
This utility makes use of orient.py(1), which is designed to work with certain types of digital camera image files. Instead of modifying the image data, it alters the EXIF tags stored with the image to reflect the new orientation. For this reason only images with the correct types of EXIF tags can be changed using this tool.
This utility is part of the official KDE add-ons module.
OPTIONS
- -90
- Rotate each image by 90 degrees clockwise.
- -180
- Rotate each image by a half turn (i.e., 180 degrees).
- -270
- Rotate each image by 270 degrees clockwise (i.e., 90 degrees counter-clockwise).
- -v
- Flip each image vertically.
- -h
- Flip each image horizontally.
