Hi Mathieu:

That would be great, if you could provide something for me.

Benjamin: As far as I understood, there is not possibility to integrate
VSI into Openslide because of proprietary format, right?
The scanner is really great for cytology. If you want to have a look,
you can go to that site:

Then go to the viewer and click on the 3rd or 4th image, which are
cytology images.

Best regards
