boost 1.47.0, os/x 10.6.8, gcc-4.2.1 apple build, 64bit

I can read a tiff, get its raw buffer, fool around with it and write it back out as tiff, no problem, but is it possible to get/write the resolution?  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.

thx
