Tiff plugin doesn't support in between bit depths about oiio HOT 8 CLOSED

I don't suppose you can supply a small example image? I bet this is easy to track down and fix.

Absolutely!

Let me know if you need more information.

Cheers!

I have a fix for this. I'm not sure how to link this ticket with a specific pull request. Does anybody else know?

from oiio.

By the way, even after implementing the fix, I am not seeing the images match. Should I infer from the names of your files that the DCDM one is in "xyz" space and therefore is not expected to be a visual match for the Rec709 one?

Hey Larry,

You are correct, the image data won't match as the second (12-bit) image is in xyz space. I can try and find a 12 bit tiff that hasn't had that transform applied.

Cheers!

No problem, I have other test images (including many from libtiff's official test collection). I just wanted to be extra sure that any remaining difference between the two example images you sent were intentional, and not indicating that there were still bugs.

Thanks for the examples and filing the issue -- I actually appreciate the opportunity to beef up our handling of the oddball bit depths.
