Hello XnTriq,
again thanks for your detailed answers.
And Yes I performed some more tests as you described in your last post.
Also the following part of your first answer is now clear to me:
I works as expected:
- In case of "keep date/time" is unchecked, XnViewMP does not perform a lossless rotation by itself.
- You can also perform a rotation with only exif:orientation changed.
But the problem is the following reading of metadata:
Because file creation-date of file in filesystem and "exif:data/time original" is different,
XnViewMP always displays exif:date taken with value 1=normal=topleft
(Exiftool display the correct value after a rotation)
So I agree: in this case alsways a lossless rotation should be performed by user.
Question: Is the above described problem a known issue or do we have to open another topic?
Thanks again and
Best regards
Herb
