Over the next few weeks I plan to extend the documentation and stabilize the main parts of the API, however binaries are already provided for an initial 'beta’ version, which I hope you may find interesting and useful.</div><div class=""><br class=""></div><div class="">Finally, I’d like to say thanks to the OpenSlide developers for making their work available. It has been an enormous help in my own battles with analyzing huge images, and in creating QuPath.</div><div class=""><br class=""></div><div class="">Best wishes,</div><div class=""><br class=""></div><div class="">Pete</div></body></html>
