Insight does not correctly view indexed image data

Reported by: rleigh Owned by: jburel
Priority: critical Milestone: Unscheduled
Component: Insight Version: 5.0.8
Keywords: n.a. Cc: mlinkert, wmoore, jburel

Insight (and webclient) do not correctly view indexed images using FS.

Example: Amira images, which are uint8 indexed with a 24bit RGB palette. These display incorrectly as greyscale with a 2 bit range! i.e. we are viewing the index, not the true RGB representation.

For these images, they must be converted to the proper RGB values. Chris said that the ChannelSeparator? ReaderWrapper? should be used for this type of image.

This also affects the webclient. See also: #9773 for screenshots of the bug in Insight and web.

See http://trac.openmicroscopy.org.uk/ome/ticket/9773#comment:4. I don't know that this qualifies as a bug necessarily, as what is happening now is completely expected.

It does bear discussion though how we want to handle indexed images going forward, so let's maybe take some time to go over this as a group when Josh and I are in Dundee.

  • Keywords FS removed
  • Milestone changed from OMERO-4.5 to Unscheduled

In discussion with Melissa, this will take some architecting and isn't FS-related.
