A portable OpenSlide viewer for Windows: Smart Zoom Viewer

[Priv.-Doz. Dr. M. Weihrauch]

Thanks for the fruitful discussion! And yes, for us the requirements (as
in one of my last mails) were serving static images for educational
purposes (no image analysis) for thousands of customers out of single
files. Our apps Smart Histology, Smart Hematology, Smart Microscope have
been downloaded >200,000 times (mostly the free test version
unfortunately :), also we have many Universities and some learning
platforms connected to our services and the tile-servers still look
pretty bored.

Best regards

Martin
