Associated thumbnails image vs Slide image

[David De Mena García]

Thanks Angelos and David: 

As you mention, Angelos, OpenSlide has
not tiles but I use deepzoom utility to compose the pyramid image. 

Off
course I can use smaller layer (and probably i will do it) but all
proprietary viewer (Ventana, Aperio and 3DH) use the thumbnails to
indicate the area where it showed so I suppose that in the proprietary
format necessary it has to be the correspondence between the thumbnails
and base image.  

Any idea where it supposes to be?

Yeah I have had the same experience. I think it's easier to just grab
the thumbnail/smallest layer, but for example if you are embedded it in
a webpage, you can just specify style="width:300px" or something similar
and constrain the width of the actual thumbnail

to have a universal solution for this. Many slide formats contain a
thumbnail that is not just a scaled down version of the original image,
but also a trimmed one. Furthermore, OpenSlide does not expose the
concept of tiles anyway, so your best bet would be to read the lowest
resolution level and scale it down further to fit your needs.

a correspondence between the associated image thumbnails and the Slide
image to compose "navigator image", so some pixel of the thumbnails will
link to some tiles of the slide base image. But I need some
correspondence between both image: is it possible to know the starting
and end point of the slide inside the thumbnails or the real size of the
thumbnails or even the mpp of the thumbnails image of any vendors?
