JPEG-Autorotate
NOTE: This repository contains the source code of JPEG Autorotate 2, which has been superceded by JPEG Autorotate 3. See https://jpegrotate.com
Adds Windows right click menu items to folders and photo files (.jpg, .jpeg) for lossless rotation of JPEG files according to EXIF orientation metadata.
(Developer details below added July 22, 2016)
All JPEG autorotate literally does is call jhead with the path given by explorer and a couple of parameters. The entire command line window that opens is called in accordance with registry keys like this
WriteRegStr HKEY_CLASSES_ROOT "Folder\shell\JPEG-EXIF_autorotate_folder\command" "" '"$INSTDIR\autooperatedir.bat" "$INSTDIR\jhead" "%l" "$INSTDIR" -autorot $setPauseAfterDone'
(https://github.com/savolai/JPEG-Autorotate/blob/master/autorotate.nsi )
Which calls the bat file ( https://github.com/savolai/JPEG-Autorotate/blob/master/autooperatedir.bat (
which pretty much only calls jhead and nothing else.
%1 %4 %2\*.jpg
%1 = $INSTDIR\jhead
%4 = -autorot
%2 = directory path
If you want me to add any parameters of jhead, I can add parameters of course. Or if you can send a patch on github, that would be great. I don't really have much time to work on JPEG autorotate and would love someone to take its maintenance over on github.
