Description
Summary of the bug:
I would like to use a 16 bit gray pixel format in tiff. I see gray8 but if I want 16 bit I need to use an rgb64 pixel format (which is a bit larger than necessary). Here's a command that attempted to create a 16 bit gray tiff image (ffmpeg uses rgb64le).
How to reproduce:
