Description

This functionality was developed in #791 and uses the JAI library for converting TIFF images to JPG. The JAI library is old and is no longer maintained. Starting with BASE 3.16 it will not be included in the BASE distribution (see ​http://base.thep.lu.se/ticket/2139). Luckily it seems like Java 11 has built-in support for TIFF files via the Image IO API. This has already been verified by the Thumbnails extension.

So, we could make this switch as soon as the production server is running on Java 11 but not later than the BASE 3.16 release.

The implementation has now been updated and it seems to work for images from the microscope.
