Images stored upside down about imageio

[almarklein]

I find it /extremely/ unintuitive that imageio (through freeimage)
expects image arrays to be upside down to be saved correctly. Virtually
every other library does it the other way. There should be a big fat
warning in the imageio documentation that I have to flip my image.
Ideally though, imageio would do the flipping for me (when reading or
writing using freeimage). Or did I miss something fundamental? Btw, I'm
writing 16bit tiff files.

AFAIK imageio saves the images in the same "orientation" as e.g.
matplotlib and Matlab do. What is your experience with these?

I was not aware that most other toolkits do it differently. If this is
the case, or if indeed its confusing, we should add this information to
the docs.

Please have a look at scikit-image/scikit-image#1101 I think this is the same issue and really a bug.

Ah, I did not understand that this was specific to 16bits images. I backported Stefan's Fix. Can you try and see whether it works?

[letmaik]

Yep it's working.

Great!
