<div>Dear Jake</div>
<div><br>
</div>
<div>We currently have a limit on the size of the image that can downloaded.</div>
<div>By ROI extraction, are you thinking of creating ROI on some of those large images and “cropping” to generate a new image then download that image?</div>
<div><br>
</div>
<div>A new script is available in OMERO 5.3, <a href="https://github.com/ome/scripts/pull/115">https://github.com/ome/scripts/pull/115</a> to generate tiles images from ROIs</div>
<div><br>
</div>
<div>We are considering a 5.2.7 release to add support for ice 3.6.3</div>
<div>So we could certainly back port the script mentioned above if it solved some of the issues.</div>
<div><br>
</div>
<div><br>
</div>
<div>Cheers</div>

<p class="MsoNormal"><span style="font-size:11.0pt">I was just wondering if there had been any consideration given to the 12k x 12k pixel limit on certain ROI Extraction/manipulation semantics in OMERO 5.3 for your road map? From what I can tell, in OMERO 5.2.x
series code, there still exists limitations on how large an extraction of an ROI can be, and the ability to manipulate data beyond 12k x 12k pixel wide dimensions.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">We’re now on a daily basis, getting significant requests/complaints from people ingesting very big things (100k x 100k pixel style stuff) who’d dearly love to work with their data – but can’t ROI extract,
nor work with it anymore, due to the fact that there seems to be a 12k x 12k limit on file format transforms (I assume it is a BIOFormats thing/BIgTIFF thing/OMETIFF limitation).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Would like to know if any progress had been made with this limitation – it’d kind of liberate OMERO for us in an amazing way/really make a lot of scientists smile…<o:p></o:p></span></p>
