Hi David,<br>
<br>
like I said, every vendor does it's own and you have to study each
format separately in order to figure out such mappings. I seriously
doubt there is a catch all solution for what you are looking after.<br>

<p>Thanks Angelos and David:</p>
<p>As you mention, Angelos, OpenSlide has not tiles but I use
deepzoom utility to compose the pyramid image.</p>
<p>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. </p>
<p>Any idea where it supposes to be? </p>

<div dir="ltr">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</div>

<p class="MsoNormal"><span>To my experience it will be
very hard if not impossible 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.<span style="text-decoration:underline"></span><span style="text-decoration:underline"></span></span></p>

<p>Hi:</p>
<p>I'm looking to find 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?</p>
