A portable OpenSlide viewer for Windows: Smart Zoom Viewer

[Josef Bauer]

Dear OpenSlide Community,

I am following this discussion very closely, because the file format of the
PreciPoint M8 SlideScanner (*.vmic) is based on DeepZoom image pyramids in
a zip container, too.
We see largely the same advantages mentioned by John Cupitt. Our customers
appreciate the quick and easy way to create static websites out of their
scans.
On the other hand, we test OME TIF (and similar tif file formats) how well
they work with openslide.
Is there a list of available OpenSlide Viewers (like the SmartZoomViewer)
for speed comparison?

Best regards

Josef
