--- Comment #8 from Sergejs <s...@inbox.lv> ---
Hello,
Despite this report being marked as resolved, from a new user perspective it
looks like digiKam 7.2 does not support lossless JPG rotation at all?
I have read through lots of documentation and could not find a definitive
answer IF and when DigiKam 7.2 uses lossless Jpeg rotation. Furthermore when I
rotate a JPG file, it all the time changes file size, so it probably is NOT
lossless?
Also DigiKam is not on the list here: http://jpegclub.org/losslessapps.html
so to clarify:
1 - is normal "Rotate Left/Right" lossless for JPG files?
2 - is "Auto Rotate/Flip Using Exif information" lossless?
I would like to use "Auto Rotate/Flip Using Exif information", but if DigiKam
can not do it losslessly, then there should be a confirmation dialog to stop
people from messing up their photos.
+ not a bug, but still:
I also noticed that after DigiKam writes metadata to JPEG files from Panasonic
camera, the file becomes a few KB smaller. This is very strange as DigiKam
presumable wrote more metadata to it than Windows Photo Gallery and yet the
file becomes smaller... Scary stuff.
