Hi Curtis,<br>
<br>
With Icy we were initially relying on the 8/16 bit color table
information of Bio-Formats but definitely almost time it's empty or
not filled according to the Channel Color field so now we check both
informations to provide default image channel color.<br>

<p dir="ltr">The ImageJ plugin does apply color tables from the
reader to the images; see ImageProcessorReader.</p>
<p dir="ltr">I think the question is more: does that Channel Color
property in the OME-XML get transformed into an 8-bit color

code last night I could not find any such logic, but may have
missed it.</p>

Hi Roger,<br>
<br>
Thank you, the Color property is exactly what I needed!
Somehow I missed<br>
that and I would never have guessed the encoding:) This was
super<br>
helpful! Do you know if bioformats, in ImageJ for example,
would pickup<br>
the stored lookup table and use it for visualization?<br>

<br>
Looking at the code in<br>
components/bio-formats-plugins/src/loci/plugins/in/ImportProcess.java<br>
it does get an 8-bit LUT, but then doesn't do anything with
it, so it<br>
looks like support on import into ImageJ is unfortunately
incomplete at<br>
present, limited to channel colour only.<br>
<br>
We do have a ticket for improving this here<br>
<a href="https://trac.openmicroscopy.org/ome/ticket/12168" target="_blank">https://trac.openmicroscopy.org/ome/ticket/12168</a><br>
as part of the model and code changes needed to improve
support for<br>
rendering.<br>
<br>
