Python and 16 Bit Tiff

Question

How can I convert and save a 16 bit single-channel TIF in Python?

I can load a 16 and 32 bit image without an issue, and see that the 32 bit image is mode F

Answer 1

You appear to have stumbled into a PIL bug, or a corner case that was unimplemented.

Here's a workaround:

i16.mode = 'I'
i16.point(lambda i:i*(1./256)).convert('L').save('foo.png')
