Hymir is a Java based IIIF Server. It is based on "IIIF Image API Java Libraries" and "IIIF Presentation API Java Libraries" projects (see https://github.com/dbmdz)
Currently, Hymir will do rotation during decoding if the ImageIO plugin supports it (e.g. with the Turbojpeg-Plugin).
This is very brittle and has a lot of corner-cases that fail, it would be best to just disable it alltogether and do rotation on the decoded image in all cases.
