<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>
<p>Best</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>
