Hi David, I would recommend to use the new io extension. You can find it here:
Let me know if the io_new solves your problems.

I understand that the res doesn't matter to the pixel content, but it *does* matter to some image processing chains. I know tiff tags support it, separately for x and y, and with different units, e.g. dpi, so I know I *could* descend to libtiff and do it there, but for me that would defeat the purpose of using GIL in the first place.
