[ome-users] Black image with BigTif and Bio-Formats

[David Gault (Staff)]

Hi Stephane,

Thank you for submitting the bug report and providing a sample file. I have been able to reproduce the issue as you described and have discovered that the problem was introduced with Bio-Formats 5.7.1 and onwards.

I have opened a Trello card on the Bio-Formats inbox to track the issue:

With Thanks,
David Gault

Dear Bio-Formats developers,

Recently we started to experience an issue while opening some big TIF images with Bio-Formats where returned pixels are all set to 0.
We used to open these images normally with older version of Bio-format (5.6.0 is ok).

I uploaded an image sample here to reproduce the issue :

As the image size is over > 2GPixels i used to open a sub resolution or just a region of the image but in both cases all returned pixels are 0. Hope it can help you in fixed the problem :)

Best,
