The script works best as a bookmarklet. Create a new bookmark on your browser's bookmark bar and set the bookmark's location or url as the script above. Example images: https://www.mv.helsinki.fi/home/mckilkki/omero/

Omero ROI extraction works in Omero.iviewer. The script is only slightly modified to work as a bookmarklet. Original creator is @Yu-AnChen
