Hi <span style="font-size: 12pt;">Benjamin</span><span style="font-size: 12pt;">​,</span></p>

Thanks for the help.
<p><span style="font-size: 12pt;">I'm using a NDPI </span>format (Hamamatsu format)<span style="font-size: 12pt;"> image. Does OpenSlide </span><span style="font-size: 12pt;">creates extra </span><span style="font-size: 12pt;">slide levels for this format?</span></p>
<p><span style="font-size: 12pt;">If so, do you know how does libjpeg do image downsampling? Gaussian pyramid?</span></p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p><span style="font-size: 12pt;">Thanks</span></p>
