For 1, both points mentioned are limitation of the client, “broken” lines will be saved as polyline.</div>
<div style="font-size: 14px; color: rgb(0, 0, 0); font-family: Calibri, sans-serif;">
We are not planning to adjust the behaviours, since from version 5.3.0 (due at the end of the month), omero.insight will be in maintenance mode.</div>

is not required to be pixel-aligned.</span></div>
<div style="font-size: 14px;">In practise, for masks, this is probably not the case , so we could consider adjusting the model.</div>
<div style="font-size: 14px;">This will require further investigation</div>

<div style="font-size: 14px;">That will be great if you could give an update at the group meeting. I will contact you off list to schedule a date.</div>

LOCI, and I have been working on adding ROI support to ImageJ-OMERO – which has entailed adding OMERO equivalent ROIs to ImgLib2. I have a couple of questions regarding OMERO’s handling of ROIs:</span></p>

curvature is lost. Additionally, changing the curvature of the line does not change the line measurements (i.e. line profile, histogram, length, etc.), despite what is implied by the documentation (</span><a href="http://help.openmicroscopy.org/measurement-tool.html" style="text-decoration:none"><span style="font-size:11pt;background-color:transparent;text-decoration:underline;vertical-align:baseline;white-space:pre-wrap">http://help.openmicroscopy.org/measurement-tool.html</span></a><span style="font-size:11pt;background-color:transparent;vertical-align:baseline;white-space:pre-wrap">).
