TYPO3 Core

Moved to image generation category as it applies everywhere, not just in Fluid ViewHelpers.

Notice that this actually applies to every location which handles resources in TYPO3. If you upload images with EXIF orientation tags, they are processed without respecting this.

There are great examples in the following repository, simply upload them through the TYPO3 file module and you'll see that width/height is wrong and the thumbnails are generated accordingly:

To fix this we first need to decide how to handle this:

1. Read the orientation upon indexing and apply it physically: no change necessary in other locations of TYPO3 but this reduces image quality.
2. Store the image orientation in metadata or similar and fix all locations within TYPO3 to respect it for processing: obviously a lot more work but the best solution to leave images unchanged.

This is solved for version 9.5 and higher with #69274 - tested with "Text and Images" CE - therefore I close it.

If you think that this is the wrong decision (or experience the issue again), please reopen it or open a new issue with a reference to this one.

Thank you and best regards
