Dear Jean-Marie and Sebastian,<br>
<br>
Thank you for the prompt reply! We are currently using the
development version and for now our service will remain in
development. Checks were made on both the downloaded pre-build 5.1.0
and on the one built locally from Github source.<br>
<br>
The problem we have is that EM images are often very large, even
greater than 4096x4096 and often float. Please could you point me to
the code where one can turn the pyramid generation off for such
images? Is it, perhaps, possible to render only a part of a large
image, say 1024x1024 slice out of 4096x4096?<br>
<br>
Best regards,<br>
Andrii<br>
<br>

Dear Andrii,<br>
<br>
as a side-note, OMERO 5.1.0 is not released yet as the OME team is
actively working<br>
on it. As a matter of fact, it is still in development and should
not be used in production.<br>
Just to make sure we are not shipping non-production versions, was
your sever built<br>
from the source code?<br>
<br>
Best regards,<br>
Sebastien

When the size of plane is greater than 4kx4k, a pyramid is
generated.<br>
The fact that you end up with a black square is a result of
JPEG-2000 not<br>
supporting floating point images at all.<br>
We are investigating options, no candidate library found
yet, we might<br>
have to turn the pyramid generation off<br>
for such images.<br>
Unfortunately in the current implementation not a parameter
you can switch<br>
off.<br>
An alternative could be to increase the limit of the plane
size before<br>
generating a pyramid.<br>
The image will be slower to load but you will be able to
view it.<br>
<br>
