[ome-devel] Loading electron microscopy MRC float-point images

[Sebastien Besson]

Dear Andrii,

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

Best regards,
Sebastien

Dear Andrii

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

Regards

Jmarie
