NDPI File Format Support (produced by a Hamamatsu Nanozoomer Microscope)

As far as I know, there is no one working on NDPI support right now.

The format is mostly understood, and is ready to be implemented. The
issue is that it would take an experienced programmer about 1-2 months
to finish the work. Because NDPI is not-quite-TIFF, a full
not-quite-TIFF reader will need to be written for OpenSlide itself.
The beginnings of this is already in the code.

Inside of NDPI, you'll find not-quite-JPEG, for which you'll need to
write a custom jpeg_src_mgr in order to hack the compressed data into
a format that libjpeg will decode.

Other than that, it's relatively straightforward Hamamatsu VMS:

If anyone is able to provide programmer time, I would be happy to
review code, assist with questions, and provide guidance. I do not
have time to work on this myself, though I wish I did.
