Openslide Usage

[Nikolay Kladt]

Hi everybody,

I have just started to use OpenSlide Python to look at Leica Slidescanner
images. While the basic usage is very simple, there is one question for
which I cannot seem to find the answer:

The scn file has multiple associated images (scanned ROIs) that have been
scanned with identical resolution. How do I access individual images or get
their bounds? It seems that the properties do not show the required
information but the file format description includes multiple images.

I think I can work-around easily by a first-pass, detecting background
pixels to obtain the ROIs on level zero using tiled reading, before
actually doing anything else but it seems that this information is
somewhere already... I am pretty sure I got confused somewhere..


If this is a problem of having test data, we can easily generate data sets
that can be shared.

Best (and thanks for writing a very promising tool),

Niko
