Details

I have svslide from scanner, that have different format from http://openslide.org/formats/sakura/
It was sqlite3 as old, but have another tables:

sqlite> .tables
gigapixel_image_contents  settings                  slides
gigapixel_images          slide_annotations         teachinprofiles
hr_scans                  slide_contexts            users
scanned_images            slide_histories
search_slidedata          slide_snapshots

What can I do here? Is any chance to read this file?

@bgilbert Hello!)

Example slide can be used with public domain license

Thanks for the report and sample! This seems to be a different flavor of Sakura slide, and OpenSlide will need to be extended to support it.
