Floating point render error back(?) in 5.2.2

[pmcarlton]

Hello,
I previously reported a problem with rendering of floating point Deltavision files (bug# 12912) which was fixed, but it seems to be back in 5.2.2.
I uploaded a new file to qa (ID: 17052) giving this problem in the OMERO.web viewer.

The same problems happen as before: bright pixels suddenly becoming black or vice-versa upon small shifts of the scaling parameters.

Thanks,
Pete

(ps. 5.2.2 renders everything much faster than 5.1.4, which is great.)

hi Pete

Thanks for reporting the problem and uploading the file.
Did you notice the problem only when doing small shifts of the scaling parameters?

We have not recently worked on this section of the code.
We will investigate the issue and hopefully have a fix in the next release
Cheers

Thanks—the problem seems exactly the same as the one that was fixed once already in June 2015 (http://www.openmicroscopy.org/community/viewtopic.php?f=4&t=7825) — thanks for fixing again and I am looking forward to the next release.
