Have you checked if the image is correctly decoded ? I think that 32bit images are encoded with floating point numbers.

What is the value of the sampleFormat field for your ifds ?

targos commented 8 years ago

Actually would it be possible that you send us the tif file ? We could use it for tests

max-mapper commented 8 years ago

@targos ok I uploaded it here: https://github.com/maxogden/messages/releases/tag/untagged-ae092b0e70fd9a33e998. It's a rodent brain volume I got from a neuroscientist
