[Fix] Add an additional/alternative auto-image-rotate option - #91
Conversation
- On our system, for a so far unknown reason, the exif data is somehow in cases of 6 and 8 not correctly processed with the core "auto_orient" checkbox option - This commit intoduces a seperate, additional handling, which basically "inverts" the image-orientation in exif data cases 6 and 8. - Background info: it should work like this: https://jdhao.github.io/2019/07/31/image_rotation_exif_info/ (and thats also how it is handled so far) but -> - that seems somehow not always reliable, see also this study here: https://www.daveperrett.com/articles/2012/07/28/exif-orientation-handling-is-a-ghetto/ - And therefore, this "workaround"-option introduced hereby

=> Use a LLL:EXT (XLIFF) label
Furthermore, I'd suggest to add a description field with some further details, such as a (textual) link explaining the problematic with some pieces of software.

Yes, can be done, i leave that up to you :-)

Please drop all those useless line breaks between cases, they do not bring anything and are not used either in the rest of the codebase.

Since this is fully related to auto_orient, I'd suggest to group both "auto autorientation" options in a single palette instead

This is more like a workaround for now. Background details:
Overall:
It seems somehow not always reliable how to act on the EXIF data. In theory i would totally agree and say that the approach described and explained here (https://jdhao.github.io/2019/07/31/image_rotation_exif_info/) and also currently taken in the core of the extension should be correct, but, under some (sadly not yet absolutely clear) circumstances, the auto-orient feature does not work - at least on our new server. And i could imagine that the same happens for the user (https://github.com/DTM-TYPO3)´s usecase in this issue #60
Also, the problem has been reported and studied already by others like:
....so thats why i introduced in this branch the additional option. Of course, in best case it would not be needed at all but so far at least it provides a workaround for us and maybe its helpfull for others ... :-)
