Olympus VSI layer information.

[wzajac]

Hello,

I was able to open and display Olympus VSI files that were supplied to me, using Bio-Formats with command line tools.
However, it seems not possible to get any information concerning relationship between IDF's in *.vsi (tiff I believe) file, that is: how different layers (like 2x, 20x, ...) are related to each other in terms of size and (i guess it's called origin in Olympus software) placement.

Is it possible to somehow extract that information from *.vsi or *.ets files with Bio-Formats?
If not, what does it take to implement it? (Olympus' specification?)

Best regards,
Wojtek

Hi Wojtek,

We are actually working on that for the next major release of Bio-Formats - you will then be able to see the relationship between the layers at different magnifications as well as the physical position of each layer. Please see also this ticket on our issue tracking system:
